The '''[[BMW]] R100R Mystic''' was a two cylinder boxer, [[four-stroke]] Naked [[motorcycle]] produced by [[BMW]] between 1991 and 1996. It could reach a top speed of 112 mph (181 km/h). Max [[torque]] was 53.55 ft/lbs (72.6 Nm) @ 3500 RPM. Claimed [[horsepower]] was 58.74 HP (43.8 KW) @ 6500 RPM. 
 
==Engine==
The engine was a [[air cooled]] two cylinder boxer, four-stroke. A 94.0mm [[bore]] x 94.0mm [[stroke]] result in a [[displacement]] of just 980.0 cubic centimeters. Fuel was supplied via a overhead valves (ohv). 
 
==Drive==
The bike has a 5-speed transmission. Power was moderated via the dry, single plate, diaphragm spring. 
 
==Chassis==
It came with a 110/80 V18 front [[tire]] and a 140/80 V17 rear tire. Stopping was achieved via dual disc in the front and a single disc in the rear. The front suspension was a  41mm Showa telescopic fork while the rear was equipped with a BMW Motorrad Paralever, Showa adjustable mono-shock. The R100R Mystic was fitted with a 6.34 Gallon (24.00 Liters) fuel tank. The bike weighed just 434.31 pounds (197.0 Kg). The wheelbase was 58.82 inches (1494 mm) long.

Unofficially, all the horizontally opposed flat-twins (the Rs, aka boxers) are retro bikes anyway. Someone needed to say it out loud, that's all, which, with a liquid-cooled four-valve flat-twin due to launch next year, BMW can now do — cashing in on the stampede for modern classics in the process. There is, however, more to the R100R than a junked fairing and wire wheels. At 20 paces it's a random bitsa, at ten it's a R100GS trailie wearing street running gear and chrome. Not quite [[Supermotard]] but not full-blown retro either.

That monolith beneath the tank is 980cc of Paris-Dakar inspired GS motor and five-speed gearbox. It gets GS big-bore carbs (other street Rs have 32mm Bings) and a smidgen more torque than the R100RS/RT — 60 snoozey bhp at 6500rpm, 56 fat lb.ft at just 3750rpm. The double-loop steel frame is GS, too: same laid-back wheelbase (longer than street Rs), same trailie rake and trail but with 18 and 17 inch wheels, road suspension and narrow bars (because the suffix R is for "road").

The forks, so often too long and soft on BMWs, are not only Japanese but have recalculated spring and damping rates over much reduced travel  135mm compared to the R100RS' 175mm. The rear unit has a longer than normal stroke but is adjustable for rebound damping as well as preload. GS/K1 Paralever, the double-jointed swing-arm/drive shaft which effectively reduces torque-induced pitching, finds its way onto a pure-roads R for the first time. It has the lowest of all BMW seat heights and only the plain R80 weighs less fuelled up — and that hasn't a capacious 24 litre tank swiped from a GS and given a golden oldie amethyst paint job.

The engine and its drivetrain crave affection. Once its been given max' choke and seven or 16 protracted blasts on the starter (the battery is indefatigable) it slogs away in its frame, like all good twins should. It chuffs dry and tappety, pulling to the right in reaction to its shaft and flywheel but now fails to squat on the tarmac like those venerable pre-Paralever police BMs. Accelerating from tickover (which vanished after speed testing) brings a lumpy judder, then a brief vibration at 3000rpm before moving into its calmer waters. Before 4000rpm are showing on an excru-tiatingly slow tacho, torque has peaked and begun to drift slowly downwards as power climbs steadily towards 6500rpm.

The tachometer zones are clearly defined: 1500rpm to 3500rpm: rough and gutsy urban punch; 3500 to 4500: lusty and smooth and where the tacho gravitates to on sub-75mph twisties; 4500 to 6000: same eager acceleration but with charm disappearing in direct proportion to rising revs, now droning like a DC-10; 6000 to 6500: noisy, should have shortshifted ages ago but there's a Golf ahead that demands a seeing to and power's still flowing; 6500 to deep into the red: shouldn't be doing this, pegs and bars are beginning to tingle, it's getting hot, the oil-cooler seems to be obscured by the mudguard, it's undergeared, my arms, neck and stomach muscles are indeed enjoying a good work-out.

Revs and redlines just aren't its bag. It's a lazy old carthorse that will break into a gallop only if it's bullied. Response is suitably languid  it likes a squirt of throttle and second-third-fourth shortshifts, which save a second bite at the throttle and drop it back into the lust zone. The box is lazy too — slow and sometimes stiff with a long throw — while the cable clutch (as opposed to the clutch lever) is light but barely breaks drive. Try booting it up one on falling revs and you'll probably fail; get the revs wrong on a downchange and the back end hops about. Neutral is difficult for the same reason, third goes missing, yet...what a great gearbox. It's fun, erm, a real rider's box. Don't ask, it just is.

The effect that lot has on the rest of the bike is boxer legend. Everything from the seat, which cushions and supports like a trooper, to the fork's and rear shock's early movement is soft and squidgey. An attacked throttle followed by an upshift invites an exchange between front and rear suspension. As the throttle's backed off, the shock unloads onto the forks which do a little shimmy before sending another message rearwards. On slow turns, like roundabouts, a snatched handful can pull the bike up and offline on lefts, or make it fall into the curb on rights. Back off mid-corner with the bars held loosely and they'll try to shake themselves free of that dreadful switchgear. Blip the throttle on the way into second gear turns and the torque reaction nudges you sideways.

Unlike the keys and switchgear, this isn't annoying  it's genuine character and holly enjoyable. But it does mean that steering accuracy is hardly its forte. Understeer, oversteer and, above 80mph, straining arms make general aiming the order of the day. It bowls along on its trailie geometry — stable (so long as the bars aren't held in a death grip), feeling just like big trailies do with much reduced leverage because of those narrow bars. Speed steering is obviously slow, real underwater biking, and takes enough effort to keep you warm in winter. The trick on sweepers is to brake early then to turn on a constant or gradually opening throttle. That way it stays neutral enough and vice free —- ask any copper the next time you're pulled.

That was no hardship either. Using the lump's low center of gravity to roll around those steep-walled and skinny Metzelers was like riding a Weeble that won't fall down. The steering lock is exceptionally useful (feet-up one lane U-turns), I could travel in comfort for 170 miles before reserve, and the whole semi-trailie, semi-retro idea began to gel. Furthermore, I got well into R100R style riding, what the police call "making good progress", and reached home as ruddy faced and refreshed as I did on the last RC30.1 stayed warm, if not dry, in snow via its two-heat grips — like a hot bath — while the engine looked after my legs. Plonking tiresome rucksacks in the boot and a happy pillion on the back (which slowed performance to that of a hot-hatch) actually damped the suspension and gave more feedback from the faultless but rather isolated Metzelers. I was in danger of becoming a convert.

The one flaw in this riding technique is that whatever you do on this bike requires big handfuls of everything (throttle, clutch, steering) but a gentle touch. Compared to a flyweight Jap' which responds to microscopic input, those levers and controls are brutish, and the brakes are no exception. The twin disc four-piston Brembos are very powerful by boxer standards (the R100GS has one twin-piston caliper) but their potential hides behind a lever that's easy to use with two fingers but really needs four. The span is too wide with much of the lever action not even getting pad to disc. When at last they bite there's more front-end dive than stopping and the wheel pulls in whatever direction it's pointing. The faster your speed, the better the brake/fork combination becomes (best on a BMW yet in fact) but coming to standstill is often a messy business. Dive, rebound, lurch, much paddling and bashing of shins on protuberances.

The rest of the good kit is very good. Mirrors distinguish Skoda from squad car at all revs; the headlight melts Shellgrip (but needs adjusting with even the most undernourished of passengers); the console is a bit placcy but ergonomically pure; the panniers only leak a tiny trickle; and the toolkit, bulb kit, puncture kit...everyone knows about that stuff. Tragically, though, road salt rubbished the alloys almost overnight. At 900 miles, a bike that hadn't even been launched to the public it was so new, looked a hard year old. And it wouldn't tickover anymore. Nor would it start in the mornings, not since Bruntingthorpe's test strip where an [[BMW R80GS|R80GS]] also went rough and dozens of [[:Category:Japanese motorcycles|japanese bikes]] in between didn't.
