Although mostly all the motorcycles we feature on BikeVX are one of a kind, however this one makes a strong impression and leaves no doubt that we wouldn’t find the same anywhere else. Probably splashy red color played its role here, but not only the color makes this build special. The bike has truly gone through a lot, has riden all over Europe and as the guys declare, even visited the Isle of Man a few years ago. Now when this machine recieved a proper treatment, has gone through many changes and upgrades increasing potential and getting some magnificent external qualities, I’d honestly consider this R90S as a one-off motorcycle in all senses of the word.
The bike first hit the road in the mid 70s, since then it has been rebuilt several times by a few talented and well known bike builders in Germany, so this isn’t the first customization of this BMW, but as the RM team explains, each one of all the previous builds was made very professionally thereby the vehicle has been retaining a really good shape.
Lets take a closer look at some alterations and upgrades the guys are pointing at. Although it’s a flat-twin engine that makes everything move, the bike feels like 4 cylinders inline engine motorcycle all thanks to several major changes. R90S has been lightened and the motor has gone through a complete “check-tuning” rebuild getting 1010 cc of capacity. Here are some important internal and external upgrades: sport profile camshaft, cylinder heads, custom made by Paul Bluhm, ultra-light flywheel, 38mm Del’Orto Carburetors and custom 2 in 1 exhaust systerm with a muffler located under the seat.
The front end and the reworked moto-shock – both were adapted from BMW K1, as well as front and rear Brembo brakes. The ignition system was changed to Silent-Hektik electronic ignition. Speedometer and Kroeber Tachometer are also electronic items.
RM team explains that since the engine overhaul the bike hasn’t gone more than 1500 km and all the changes have been approved with the German TUV.
I think this is one really eye-catching bike. For more information on this R90S head over here.
