Electric, 2×2 and riding UBCO’s utility bike

ubconz3-1

Are we ready for electric motos? Probably not, but I did a twitterpoll  and it looks like we certainly want them.

2025: UBCO goes bust

Ruckus

I’ve always liked utility bikes (‘ag bikes’, ‘farm bikes’) where functionality is measured in terms of load carrying and off-road agility, rather than tarmac-creasing acceleration or foot-long suspension travel. They even get their own section in AMH8, left. For the right sort of gnarly adventure, or with a recalibrated attitude towards pace, bikes like Honda’s AG190 (left) could make a tough little travel bike.
Ag bikes possess that do-anything, go-anywhere appeal, which must also be behind the adventure motorcycling phenomenon. Yamaha’s TW-inspired Ryoku concept of a few years ago (below right) seemed to bridge both segments.

Whether intended or not, UBCO’s 2×2 electric utility ‘moped’ may also benefit from this ‘I-could-if-I-wanted-to’ conceit. People need personal mobility, sure, but many like to be feel cool while doing so, be it in a RAV 4 or on a GS12 or Raleigh Chopper.
While staying in an affluent suburb of Sydney recently, along with skimpy urban scoots like the Sachs (above left), Chinese urban retros similar to the Mash Roadster as well as a few XSR7s outnumbered anything else I saw on two wheels there. In fact it’s said bikes like these are now beginning to outsell adventure-styled bikes. Expect Bike Shed franchises to start popping up like Pizza Huts.

The Ryoku never got off the drawing board, but Honda’s recent X-ADV adventure scooter sought to capitalise on that urban adventure cachet. But after riding one – and even though I now have DCT out of my system – I felt something more akin to the current Ruckus moped (left; not sold in the UK) would have been more fun.
In Australasia and South Africa, ag bikes have been on the scene for ever, but have changed little since the 1980s. What you want is an ag bike’s utility with scooter-like ease of getting on and off – a mini X-ADV. But do you also need 2WD and would you choose electric?

2WD motorcycles

2wdsYou can be sure that one long winter some obscure engineer-farmer has experimented with front-wheel drive long before most of us were born. The vid below is one of many crazy-arsed compilations on youtube. And a couple of years ago Visordown dedicated one of their Top Tens to 2×2 motos, some pictured right.

At that time Visordown said: ... a modern generation of batteries.[…] and hub-mounted electric motors mean that … this must surely be the future of two-wheel drive – allowing almost any bike to be adapted to drive both wheels.

Such predictions proved to be on the money. If AWD is seen to be as desirable as it was when Audi introduced the Quattro road car in the 1980s, then the advent of hub-mounted electric motors is by far the least complicated and most elegant way of doing it. Ask Nasa (above) or even Ferdinand Porsche.
The mechanical or hydraulic solutions powered by an ICE (internal combustion engine), as in the vid above, are mostly just too clumsy, expensive, complex or otherwise lacking in real-world commercial potential.

Off-road the benefits of AWD traction is obvious. I can think of many sandy pistes in the Sahara (above; Algeria) which would have been a whole lot easier and therefore safer to ride with the addition of front-wheel drive. Just like in a 4×4, AWD means you can tackle loose terrain like sandy ruts or dunes without resorting to momentum (aka; speed) which will catch you out (right). And in my experience in the desert, a 4×4 with an automatic gearbox is an unbeatable combination, especially on slow rocky climbs or in soft sand. Just the right amount of torque is fed to all the wheels to give traction, and on rocky trails there is no risk of stalling, again allowing you to concentrate on precise wheel positioning and clearance issues.

Automatic scooters are common, proper motorbikes less so, but do you even need 2×2 on a road bike? The answer is: not really. While road tests affirm that Yamaha’s recent ‘2FW’ Niken (above) delivers eye-opening improvements in front-end grip, on the road 2×2 would only benefit acceleration, by spreading the torque to both wheels and so  limiting wheel spin (just as front and rear brakes improve braking all round).
But advances in electronic traction control and tyres to match have proved just as able in optionally eliminating wheel spin. Combined as it is with ABS sensors, TA probably adds just a few ounces to a bike’s weight. Any front-wheel drive system would add several kilos while drawing overall power.
All up, the US-built 200-cc Rokon below is the only successful production 2WD motorcycle – a two-wheeled tractor that looks even less comfortable to drive on anything easier than a wooded hillside and for most people has has probably been superseded by AWD ATVs, even if the latest model features the miracle of front suspension.

UBCO: Electro Glide in White

ktmmacina

UBCO stands for Utility Bike Company, founded in 2015 when the work of a couple of creative Kiwi engineers got picked up by entrepreneur, Tim Allan (riding, below).
In 2018, after the original off-road only model had spent a couple of years in development with Kiwi farmers, a fully road-legal, version was released for global export. It’s the world’s first production 2×2 electric motorcycle aimed at farmers, rangers and forestry, while also being bought for urban deliveries and just plain off-road fun. Being restricted to 50kph, it’s classified as a moped which in many territories means it can be ridden on just a provisional licence.
You can add luggage or wider racks and run power tools off it. To recharge the 16-kilo battery takes 6-8 hours. The bike is made in China and in NZ and Australia costs $8000, (about £4200) in the US it’s more. That’s about the same price as a KTM full-suspension e-bike (above right) I saw in an NZ shop window.

Wisely, UBCO dodges competing with the likes of recently folded Alta or Zero who produce(d) full-sized electric road-legal motorcycles. Instead, it’s aiming squarely at the utility market where the benefits of a light, rugged, easy-to-ride and near-silent all-terrain bike outdo its limitations in range and performance.

Weight is 65kg and with 2.4kw (3.2hp) via the 48-Ah, 50-V Lithium-ion battery, power is less than an ICE moped. But 90Nm or 66 ft lbs of torque across two wheel is a figure equivalent an 800cc bike, and all that torque is delivered instantly to each wheel so both will spin as you pull away on loose dirt. Electrotoque is not really comparable with ICE torque: old but interesting article.
Very few electric motorcycles have motors in the wheel hubs. Once you get beyond a moped power level, they become too heavy and bulky so need to return to the typically central ICE location. Above (the two sides of a hub motor), the number and size of copper windings correlate to the power, and these motors are designed to spin fast, hence the three reduction gears on the left. The UBCO’s motors are about as small and low powered as they get on an e-moto, so hub fitting is not a problem. There’s just the low, centrally positioned battery with a power cable reaching out to each hub. Simple.


Tim, myself and his mate JB set off along an overgrown MTB trail at the TECT Trail Park close to Tauranga where UBCO are based. No clutch or gears, no heat, drive chains or belts and virtually noise, plus hydraulic MTB brakes, speed-calibrated regenerative braking and low CoG and seat all make the UBCO effortless to ride. Along with the cleated footrests, it all means you can concentrate on fern-dodging and where to put the front wheel.

Unlike an ICE moto, terrain permitting an electic bike is most efficient with the throttle at the stop and hard acceleration doesn’t consume power like it does on an ICE. Despite its optimal traction and light weight, the low power rating means it’ll only climb 1:4 at which point the short-action throttle is pinned. If you run out of go it’s dead easy to hop off and push. Even with my weight, I found what looks like basic suspension well suited to the bike’s speed potential and the terrain we rode. It’s operation never intruded on my ride and it never bottomed out.


I can’t say I noticed the 2WD, apart from wheel-spinning when pulling away on loose dirt, but it rode as on rails despite the Kenda trials-pattern tyres being at road pressures. The 2×2 has no negative effect on the steering, probably quite the opposite, but you barely notice it. Just like I found myself pressing air for the foot brake, it probably takes a while to believe and then fully exploit the front end’s drive. And no, it won’t be more efficient in one-wheel drive (like old-school 4x4s could be) – the small motors are designed to work most efficiently together. As you can see below, the air-cooled hub motors (the only part of the bike which gets hot) aren’t fazed by shallow water crossings either.

Sure, the MTB handlebars were way too low when standing up, and there was nothing to brace the legs against. But the UBCO is so light and power levels so manageable it didn’t really matter. When sitting down I found my knees banged against the frame, but some trousers or pipe lagging would fix that.
Just like a DCT Honda, the lack of gear changing or fear of stalling really frees the mind to deal with other things, meaning you can ride more smoothly and have more fun doing so. Before I got my current Himalayan I considered adapting a DCT NC750X into something akin to the Rally Raid CB500X. To me this is one of the greatest benefits of electric bikes. Doing the same ninety minutes riding on any sort of ICE dirt bike would have left me comparatively worn out.
The fast-paced off-roading we did would give you about 40 miles range – you’ll get nearly twice that on a flat road at 20mph. And the regen braking means coming down a long pass actually adds a bit of charge. The dash info is basic and includes the temperature of each motor, but you can change or monitor various functions with the bike bluetoothed (or some such) to a smartphone app. Lights are LEDs up to a very bright 2200 lumens.

At the end of the ride I was able to nose the front wheel against the back of the trailer, turn the handle and let it climb up. But even without the 2×2 or even the utility element, like the Sachs moped above, the UBCO can also pass as a cool-looking urban runabout. In the right setting it would be a great way of nipping around without frightening the horses.

milkfloatIn 1967 the Electric Vehicle Association claimed that Britain had more battery-electric vehicles on its roads than the rest of the world put together. Almost all were milk floats (right) rated at around 8-10Kw and with a range of 50-60 miles.
Even then, the first Golden Age of electric vehicles can be dated back to the start of the 20th century when, in the US for example, 40% of cars were steam-powered, 38% were electric (about 34,000 in total), and just 22% were dirty, smelly, noisy, rough-running ICEs. Then major oil fields were discovered around the world and before domestic air travel became the norm, the interstate road network went on to outstrip the railroads
. Now there are well over a billion ICE road vehicles in the world, about 20% of which are bikes. The total number of EVs surpassed 3 million in 2018, a 50% increase over 2016.

Electric Bikes

The future will be electric, again. That may well be the case in urban settings or for other short-range applications. In 2008, alongside the more common pushbikes I was amazed to see electric scooters (right) whooshing around the streets of Kashgar, western China. And in Auckland last week I was equally intrigued to see dock-free e-scooters (left) either left on the pavement or whizzing about between pedestrians.

But any form of trans-continental overlanding in the less-rich AMZone will probably be the last place to see e-motos. The world is just too divided between rich and poor, urban or rural. Just as with fast internet or mobile phone masts, the cost of installing the necessary infrastructure everywhere is too great. It’s an overlanding quandary which has become analogous with diesel cars. Low-emission engines designed to run the low-sulphur fuel sold in rich countries will play up on the old, high-sulphur stuff sold in some parts of South America, Africa and Asia where emission regs are less strict and ‘Euro 5’ is a football tournament. So while in the next decade you might be able to ride your e-moto across Europe or North America, as things stand Cairo to Cape or Prudhoe Bay to Ushuaia will be a challenge for a long while.

Visualising a sunshine-powered, off-road coast-to-coast traverse of Australia, similar to their World Solar Challenge race, I asked the UBCO tech guy would the necessary 400-w solar trailer (about two panels on the left) do the job? No. A battery can’t be charged and discharged at the same time, but a spare battery could be charged. Broome to Adelaide at 30mph max would sure give you plenty of time to get a nice sun tan.
Some say the specific problem with electric motorcycles (as opposed to e-bikes, cars or trams) is that, price apart, with the available technology the weight vs power or range doesn’t add up with current perceived expectations of what a motorcycle can do. It ends up either too heavy, too slow or runs out of charge too soon. But even Harley’s turbine-smooth Livewire (above) only weighs 210kg, does 0-60 like a 701 and might last 100 miles. We’ll know more (or not) when the Long Way Up comes out this autumn. Other electric bikes will do better. As we approach the fabled Tipping Point you’d hope things can only get better.

Himalayan 411: improving the seat

Himalayan Index Page
a44

Just back from my first long ride on the REH; a chilly 130 miles up to Simon’s near Bromsgrove to get some work done while I’m away. After what feels like weeks of dawn-to-dusk clouds, I picked a bright sunny day with a very cold northwest headwind. Wiring up the heated jacket would have been too obvious; instead I settled for my old onesie which did pretty well considering it was 2-4°C. I did lessen the windchill by spinning off the M40 at Oxford onto the lovely A44 through the Cotswolds, instead of slabbing all the way up the M40/42/5. So a good road test: weaving across busy London, dual carriageway then motorway, A roads and finishing off on B and C roads. All that was missing was some piste. That will come later.

a444

I have to say I am really quite impressed with the Him. Or should that be relief it’s not anywhere near half as crap as I feared. It starts from near freezing with a bit of cold-start lever and settles readily down to an efi-steady tickover; it manoeuvres through town easily, then spins up to an indicated 65mph with no effort and with what feels like a little in reserve.
Things may change but there’s something about the wide, 5-speed gear ratios allied with a long-stroke and low-compression motor which makes the Himalayan satisfying to ride not very fast. Maybe it’s the high torque-to-power ratio – an engine characteristic that’s always appealed to me but rare these days. You’re never in a rush to change up a gear to avoid annoying buzziness because there isn’t any. The speed range in each gear is broad so you can chug through villages without changing. It’s something I’ve not felt on a bike for years – a ride to Cornwall on an SR500 in 1980 comes to mind. And I suspect the weight with a low centre of gravity is a factor too, aiding the planted feeling. Whatever, it works for me for the moment.
In the city it felt manoeuvrable, slim and adequately responsive and on the motorway I didn’t feel unduly vulnerable. Once warmed up the fuelling feels spot on and the gearbox is fine as long as you don’t rush it. With long shadows all day, the country roads stayed wet with dew or melted frost, but the Pirelli MT60 tyres gave no moments. The brakes are OK for the speed potential, with one ‘ABS moment’ which unnerved the hard-braking car in front more than me.
The shock preload is on the lowest setting but suspension is firm and might even be classified as harsh. Better that than the opposite, although I presume it will soften up and eventually go off. I’m wondering if the YSS shock will even be needed for Morocco.
So, my first impressions pretty much match those of my short test ride a few months ago. Some of the negatives I’ve got used to or have proved not to be deal breakers.
End of February I look forward to picking up a much transformed machine, ready for the desert.

• Feels easy to ride and manoeuvre, despite the 194-kg kerb weight
• Low seat height (800mm; 31.5″)
• Indian build quality looks solid
• Torquey efi motor starts and fuels smoothly
• Pirelli MT60 tyres (as opposed to some obscure brand)
• Suspension surprisingly firm
• No vibration at up to 65-70
• Oxford grips pack out some heat
• It’s different!
• Soft seat foam (for my weight)
• Screen too small (for my height)
• LED display could be larger and tidier

Quick seat bodge
A 50-mile round trip to Crawley revealed the need for some urgent attention to the seat, just as I  noted on the original test ride. The seat sets my back off, like the WR250 did two years ago. That led to months off games – don’t want that again.
I couldn’t put my finger on what’s wrong but assume it’s a combination of dead upright seating position on to soft foam + cramped shuffle space due to the seat step + low seat height for my stature (too much knee bend).
Unlike the WR, the Him has loads of seat height to spare for my height, so the simplest  fix is more padding. I snipped out a couple of layers of cheap 10mm closed-cell sleeping pad (‘karrimat’) kept in place by my Aerostich Sheepskin Saddle pad. You can buy something similar on ebay.uk for £22 but they look rather ‘nice-to-stroke’ furry rather than the tight, woolly curls of the Aeropad which is presumably what provides the required spring and ventilation. The foam sits against the bike’s grippy seat, and the underside of the Aero also has a non-slip texture (right).
Came the day I set off up the A44 and… for the 10-minutes of bodging the ride comfort was a slight improvement, but not night-and-day. I did the 3-hour run non-stop and didn’t feel crippled on arrival which must say something, but I was too cold to feel anything much. Any height gain felt negligible but the step did feel a little reduced so I can move back a bit from time to time.
The cheapo foam I fitted was way too soft, but now the idea’s proven, I found some firmer slabs of rubber foam, trimmed and rounded them off to profile the seat, then fixed it under Aeropad. It looks a bit rubbish and the wool of course prone to getting- and staying wet. I later fitted the foam slabs under a Cool Cover and it worked well.

Rubber foam slabs cut to shape. Not sure it’s rubber? Stick a lighter to it; you’ll recognise the smell.
Under the Aeropad – it helped level off the 2-part seat but looks a bit crap.

In mid-summer 2018 I rode my XSR Scrambler from Wales via Ireland to Tarbert on the Kintyre peninsula of southwest Scotland got published in RIDE magazine.
Here is the rest of the story and the missing photos.

WITour

West of Tarbert a single-track road wraps round the Knapdale peninsula to face the isle of Jura where a dying George Orwell wrote 1984 in the late 1940s. Riding along the B8024, I passed the huge and sinister-named Landcatch Natural Selection fish farm towards Loch Caolisport. 

The B8024 leads back to the east coast of the Kintyre peninsula, while on the north side of Loch Caolisport, a side road ends within a couple of miles at Ellary. However, study an OS map and you will see an intriguing hill track which leads up and over the spur to join up with the backroad on the west side. It’s a shame that green laning as we know it in England and Wales is outlawed in Scotland. Walkers, mountain bikers and kayakers can roam and camp freely, but estate landowners and locked gates exclude motorised vehicles. Actually, as someone who enjoys all those recreational activities as much as I do trail biking, I support the restriction. Open to one and you must open to all, including irresponsible twats – in the Covid staycation summer of 2020, this right to roam rule was pushed to the limit in Scotland by motorhomers and the like. This track was closed but some private roads can be used with permission. 

Yes there is if you ask nicely.

Contacting Ellary estate office a few days earlier, I’d got permission to take the 3-mile hill track over to Kilmory Chapel. The part-eroded road was do-able on the semi-scrambled XSR and as always, it sure is fun to get off a regular road, park up and enjoy the views.

Coast road to Ellary
On the hill track; not so exciting.

Heading on towards Oban along on the A816, I took a detour to Seil Island over the elegantly hump-backed Clachan Bridge. Built well over two centuries ago to help access the islands’ slate quarries, it’s grandly known as the original ‘Bridge over the Atlantic’ Scotland has gained a few more of them since then.

Crossing the Crinan canal.

Later that evening the Calmac ferry nudged into the harbour at Tiree. Said to be among Britain’s sunniest places, it’s also one of the windiest, giving clouds little chance to hang about. Only ten miles long and half as wide, you could ride the entire road network in less than an hour, but of course that’s not the point of visiting such places. One of the Hebridean ‘machair islands’, the fine, wind-proof grass thrives alongside azure sandy bays.

Next day I did another sunny lap of the island then caught the once-weekly ferry to Barra at the southern end of the Outer Hebridean archipelago and once ashore wiggled my way down south over a causeway to Vatersay. Evoking the former Nordic occupation of what they’d called Havbredey, the ‘Isles on the Edge of the Sea’, I parked up and scrambled up to the trig point on Heiseabhal Mor, the westernmost hill in Britain accessible by road and scheduled ferry services. Formed of three-billion-year-old Lewisian gneiss (the oldest rock in Britain) eons of Atlantic gales had shorn the rounded summit into a bald dome.

They call that island Dutchman’s Cap. Treshnish islands, halfway to Mull.

North of here I was on familiar ground, scooting across the archipelago linked by causeways and ferries to Lewis and my last ferry: Stornoway bound for Ullapool.  Whether you get here by bike or on the end of a cormorant’s beak as Norse legends recall, it’s always a thrill to visit such wild places, even if they’re just a couple of days ride away.

TPMS – a good idea

Updated Summer 2023

Tubeless Conversion Index Page
Michelin TPMS review

flat

It’s not impossible to get a bit cynical about the flood of gimmicky gadgets, products or optional features which modern technology has enabled, not least when associated with ‘adventure’ + ‘motorcycling’. But I believe that for the:
• price
• ease of fitting and
• non-interfering redundancy
a wireless Tyre Pressure Monitoring System is a worthwhile addition to your bike, whatever you do with it. 

For as long as I’ve been on the road, tyre makers and road safety tsars have harped on about the importance of maintaining correct tyre pressures. They’re right of course: doing so is a major contribution to road safety for the reasons illustrated vividly in the videos below. But modern bike tyres are so good that I’ve often inadvertently ridden on drastically under-inflated tyres for weeks and not even noticed. 

nureyev

Add the fact that on some bikes the valves can be awkward to access with tyre gauges which themselves are hard to read or flakey in les developed countries. Plus it’s all grubby down there and your knees/back are no longer like Nureyev in his prime. Unless you’re a certain type of ATGATT swot, for day-to-day riding it’s all a bit of a faff to check tyre pressures as regularly as they advise. And yet your bike’s other vital signs: oil pressure, battery charge, temperature, lights and even which gear you’re in – are all conveniently lit up right there on the dash.

Tyre Pressure Monitoring System
The problem has always been how to read the pressure inside a tyre that’s spinning around at 1050rpm. Solution: inexpensive wireless technology. A TPMS is ingeniously composed of two replacement valve caps fitted with centrifugally activated pressure sensors.

They pair wirelessly with a watch-sized display mounted where you can see it (or beamed to your indispensable smartphone; right). The TPMS display is either powered off the bike’s battery or is rechargeable in some way, so it’ll work on anything else with a regular Schrader valve, even a pushbike.
Result: real-time tyre pressure and even temperature monitoring (right). And best of all, the USB rechargeable ones like the Michelin-branded one I tried, don’t interfere with the bike’s systems in any way. If the caps play up, just refit the old ones. They weigh as little as 8 grams so are unlikely to cause tyre-balancing issues at normal road speeds.
Over the years I’ve found DIY, as well as other tubeless conversions like Tubliss and BARTubeless, have gradually lost air pressure faster than a regular tyre, tubed or OEM tubeless. And this is even when not run at very low psi where the tyre could conceivably ‘burp’ out some air over a bump. With any sort of DIY tubeless conversion, I highly recommend fitting a TPMS; certainly in the early days until you know how good the seal is.

Tyre pressures increase with elevation as ambient pressure falls, but they also drop as temperatures fall. For every 2000 feet (600m) you climb, the pressure will increase by 1 psi and will fall by the same amount for every drop of 4°C (10°F). But as temperatures naturally drop with elevation, things kind of balance themselves out.

82~up-creek

Riding Off-Road
As we all know, lowering tyre pressures greatly improves traction on loose surfaces and can transform a bike from a mindless shopping trolley into a hyper-sapient roller blade. But when you lower tyre pressures, temperatures in the tyre carcass soar as it flexes and influxes much more on each rotation, just as you get hot exercising because your muscle tissue is rubbing. And as tyres heat up pressure readings climb. (This is why cold tyre pressures should be your baseline). In this hot, rubber-softened state a tyre is much more prone to punctures and other woes.

Off-road I tend to keep pressures as low as necessary but as high as possible. Usually erring on the high side at the cost of a comfy ride, so weary am I of repairing flats on tubed tyres in the middle of nowhere (left).
A TPMS won’t stop punctures but at least you’re able to observe how pressures climb from a cold start and what they’re actually doing on the dirt, so helping eliminate the guesswork of ‘press valve for 2-3 seconds’ or the nagging feeling of ‘should I stop and inflate a bit?’

You can buy obscure-brand TPMS kits for your bike off ebay from £30 for the smartphone-only ones. About £50 seems a good price for a decent one. Here’s an Advpulse review on a hardwire Cyclops TPMS (above left) which sells in the US for $130. Cyclops aren’t tyre specialists, they just sell gadgets and a near-identical looking kit can be bought on ebay UK for about half that price (above right).

A TPMS is one gadget I wish I’d had on my Tenere back in 2007, if not all my desert bikes over the years. I fitted Michelin’s one to my all-tubeless Himalayan and semi-tubeless Africa Twin in 2020. Read the review.

Adventurising the RE Himalayan

Himalayan Index Page
himalio

For what you pay and compared to vaguely similar bikes, Royal Enfield’s 2018 BS4 Himalayan comes very well equipped: centre stand; small tail rack plus tank sideracks; small screen; 15-litre tank giving a 400-km range; a small bashplate plus suspension that need not be instantly written off.
Most of those items won’t need improving, but when did that ever stop anyone? Below, I throw out some ideas to help turn the Himalayan into a functional overlander. As with all my project bikes dating right back to the XT500 of 1982, I like to experiment with new stuff and new ways of doing things, much like Enfield’s Himalayan itself.
It’s all part of the adventure and if nothing else, it’s good for the book.

MT60

Wheels & Tyres
Out of the showroom REH’s come shod with Brazilian Pirelli MT60s (right; mine stamped ‘2012’…). The spoked rims are steel: 21 front, 17 on the back. The Pirellis would have been OK for a regular Moroccan ride, but because I’ll be heading into the sands this time, tread becomes a little more critical. Below, some tyres of interestMotoz Tractionator Adventure; Anlas Capra X and Michelin Anakee Wild.

unsprungweight
him-17-18
Confirmed: 17 is smaller than 18!
him-swingspace

One thing I’ve quickly discovered is that none of the above tyres come in the stock 120/90 17 size. The only similar tyre I know of is Mitas’ E-09 which I tried on the XR400 in Algeria; a great desert tyre. Generally 17s tend to be low profile tubeless-ready adventure tyres suited to bigger, more powerful machines, and 18s are for traditional dirt bikes with taller profiles giving more sidewall ‘suspension’ or ‘footprint’ at low pressures. The above trio come no smaller than 130/80 17. There’s probably only a few mil in it, but I’d rather not go overboard with a ‘bigger-must-be-better’ rear tyre. Too much rubber to rotate will make the Him even more sluggish.
Swingarm space with the stock MT60s (left) shows plenty of room to the sides but about an inch at the front, so for a replacement, actual dimensions may matter. The MT60 is 122mm wide and currently 93mm high from the edge of the rim. The swingarm gap will increase a little as the tyre wears and the chain stretches. Ratio-wise, 120 x 90% technically = 108mm tyre height, while 130 x 80% = only 104mm, so a 130 ought to have a lower profile or height. So even a 10mm wider 130/80 17 tyre will easily fit the Himalayan. Interestingly, an Anakee Wild 130/80-17 M/C 65R TL weighs nearly 50% more than a Wild in 120/80-18 M/C 62S TT (5kg) because the former is tubeless and aimed at heavier 17-rear bikes. An  Anlas CapraX 130/80 B17 weighs 6.1kg. Motoz don’t know yet.
Fitting an 18-inch rim might expand tyre choice at the slim 120/90-ish end. But with half an inch more radius in the rim, taller 18s could become a squeeze against the front of the swingarm unless a chain link is added to move the wheel back a bit.
An additional incentive to move to an 18 is a chance to replace the stock steel rim with an alloy rim which will be a bit lighter. Suspension and steering, as well as acceleration/braking all react more readily if the unsprung weight red, below – is kept to a minimum.

I read on the internet that the effects of unsprung weight includes the rotational mass of the gyroscoping wheel, plus – at non-rallying speeds – the less critical up-and-down mass the suspension has to control (image below). Additional unsprung weight takes more power to turn that mass, more brakes to slow it and better suspension to control it. This mass can be reduced by carefully considering tyre weight, not just the size, tread and price, going tubeless (eliminating heavy-duty inner tubes), as well as lighter rims, chain, rear sprocket materials; forks/swing arms and braking components.
I’ve always thought this is a much overlooked area of weight saving on bikes, where changing a pipe is often used as an excuse to save weight. I remember the alloy front wheel on my XT660Z weighed a ton, partly because of the OTT twin discs when one good disc was all that was needed. Cheap stuff can be heavy, even in alloy.
The image below illustrates how much greater the reaction forces are with heavier wheels. Put another way, it’s why your trainers weigh only 320g. ‘Add lightness’ as the old racing adage goes.

And if I’m messing about with rims it would be a shame not to go tubeless, for all the usual reasons. See the link, but basically it’s: DIY mastic as on my 660 Tenere, Outex tape (~£70, never tried), BARTubeless (~£320, as on the 500X RR) and Tubliss (~£180 a pair; as on my GS500R), or a suitable rim (rare/expensive).
If I go to an 18 I’m thinking of giving the 2nd generation Tubliss (right) another go as it’s an easy and inexpensive fit, but they only come in 21, 19 and 18 inch, not 17.

Is this all going a bit far with a humble Himalayan, or making the most of its potential? Will I or the bike notice the difference of a lighter wheelset, once all the other junk is added? Unfortunately I don’t have enough time to get a solid riding impression of the stock bike before setting off.

Load Carrying
One of the REH’s distinctive features are the tank racks which some mistake for tank protectors. They’ll do that too but to me they’re clearly a handy place to lash items or bags. The previous owner had a similar set-up using Kriega drypacks and helpfully wrapped the Royal Enfield badge in string to stop it getting worn away.

rigg
Lomobags

Kriega is one way of doing it, so is Lomo who’ve sent me a pair of their PVC roll-top crash bar dry bags to try (£39 pair). At around 6 litres each they look ideally suited to the racks. I plan to mount them semi-permanently and will use Lomo’s same-sized orange ultralight dry bags (£3) to lift everything out easily when lodging. In the US the more boxy, 3L Rigg fender bags (right) look like a neat fit too.

Then, once I zip on my Giant Loop tank bag, most of my daytime needs will be in view and at arm’s reach, meaning what’s behind can be left strapped in place. It may even mean I can do without a daypack on my back, plus the crash bags will keep the wind and rain off my creaking knees.

him-rak

For the back an Enfield pannier rack is has just turned from India for under 80 quid. Looks like a hefty set up – it weighs over 5kg. You’ll find them sold on ebay, or at twice the price from UK sellers. I’ve not decided what bags I’ll use on the side. At the simplest I can just lash on a couple of rugged PVC dry bags, as I did with the Rally Raid 500X a couple of years back.

him-tail

And right at the back the narrow tail rack has taken my long-suffering Touratech tail bag – one of my all-time travel luggage favourites.
Having all these bags spread around the bike is handy for access, compartmentalisation and weight distribution but at, quite literally, the end of a day, it does mean more faffing about to get it all indoors when the parking is less than secure.

barkbt06

Comfort: handlebars; screen; saddle
The bike came with Oxford heated grips – luvlay juvlay. My old Barkbuster Storms will also get their nth outing on an AMW project bike, but it looks like they’ll require BTC 06 curved adaptor clamps (right) to get under the brake lines and so on (they didn’t fit).

him-bars

Talking of which, with this ABS model (brake line goes under tank to the pump, not straight down to the wheel) I’m not sure there’s enough slack to get much more than an inch of lift on the bars, which means my 50mm Rox Risers may have to sit this one out (they didn’t). Non-ABS Hims ought not have this problem. As it is the stoop for me isn’t too bad and the general position is of course much better than the XSR. I only tend to stand when I must, but that’s partly because I rarely ride a bike where prolonged standing off road is comfortable. One way to dodge the stoop is to lower my height by removing footpeg rubbers. Wearing very thin socks also helps. Fyi: ABS switch hack.

him-screen
mra_x-creen_sport_xcsa_spoiler_animation

The screen is better than nothing and has a tiny bit of fore and aft adjustment. It’ll be all that’s needed off-road; less so for a long cross-country ride. You can get those clip-  or bolt-on deflectors like the adjustable MRA Xcreen (below right) which I had on a recent Tiger (we don’t talk about that bike) and which worked well for what it was. Or Hitchcocks Enfield specialists do a taller version, but only by 60cm. Changing a fixed screen is a gamble while others have found chopping it right down greatly reduces buffeting. Much depends on your helmet, height and attitude to discomfort. You’ll never get it right all the time and it’s all part of the biking experience, so unless you know what works for you, by far the best screen is something adjustable like the Xcreen or the Palmer I had on the CB-X.

aerosheepad
coolcover

It doesn’t feel like the seat will sustain my post Xmas mass, sprung or otherwise, for more than an hour or two. Nothing new there.
I’m getting a mesh Cool Cover to test. One good thing with fitted covers like this, as opposed to airbag seat bags, is that you can securely stuff added padding underneath without having to do a reupholstery job. I’ve got an old Aerostich lambs wool seatpad (left) which used alone may have had its day, but under the Cool Cover may add a bit more cushioning. One good thing on the REH is the two-part seat; it makes any foam-hacking job a bit less terminal.

Suspension
I’ve often wondered how much more it costs in time and money to make stock suspension which works out of the crate. There must be no shortage of data and algorithms, so maybe it’s the time in fine tuning an individual model where the costs pile up. We’re so used to regular bikes coming with great engines which can sing and dance in four time zones, but have adequate suspension which presumably is expected to work for most riders at moderate speeds. Crank up the speed or reduce the surface quality and composure soon slips away as suspension travel gets eaten up, as I found on my CB500X and XSR700. But on my BMW XCountry I discovered what decent suspension actually meant: not that obvious on road, but a whole new world of control as dirt turns gnarly. Problem is that’ll be no change from €1000 and trip to Holland, please.

him-shock
yss himalayan
hypershock

Many reviews say the Himalayan’s suspension is pretty good for what it is, which is all the more surprising when you look at the seemingly spring-bound stock shock above. I read it’s not trying to be progressive but a dual rate spring and in fact there is a 2mm gap between the closely set coils.
Currently the only outfits offering shocks are Hyperpro (right; €500) and YSS (left; made in Thailand). Unusually, both come with rebound damping but the YSS also has adjustable height and was just £270 from Wemoto on special. For that price it’ll be worth a shot and the option of dialling in a bit of extra height will be handy. As it is, the bike tends to sit a little too upright on the sidestand and adding a sandfoot won’t help. And also if I do go for an 18-inch rim where the tyre range is taller, a bit more space will be handy

him-fkprl

For the fork YSS also make a kit (above left) costing not much less than the shock. It includes valve emulators (available separately for around £80), something I’ve read of but never tried. For the moment there’s nothing to be lost by starting with some Chinese ebay fork pre-loaders (£10; left; as tried on the XSR). After that I may move up to a firmer K-Tech spring if they’ll make me one. Firmer springs may be enough to bring the front end back up if an 18-inch rear rim is fitted.

Ancillaries
I’ll hard wire the trusty Montana in and fit a RAM mount on the bars. I’ll also add a PTO for the Powerlet heated vest and type pump. The claimed 220w alternator output is nothing special, but some wattage has been freed up with dinky LED indicators and there’s a spare LED headlamp which came with the bike. Otherwise I plan to add a switch so the lights aren’t on 24/7. There are times when you don’t want to be seen too easily.
Last but not least, the Trail Tech engine temperature gauge from last year’s XR will get wired on to some very hot part of the Enfield’s engine. With an oil and air-cooled motor, even a low output one like the REH, it’s all the more important know how hot things are getting down in the engine room.
