Fuel Turns BMW’s R100 RS Tourer Into A Slick Retro Street Tracker Motorcycle

While BMW’s R100 series has become an increasingly popular platform for customization, the Bavarian boxers have never been particularly conducive to the tracker genre thanks to the shaft-driven powertrain with its large protruding cylinder heads and the bike’s more than 500lb curb weight. Despite this, the crew at Fuel Motorcycles has managed to defy the odds, delivering a custom airhead-based tracker that ticks all the right boxes.

Starting with a 1979 R100 RS, the custom motorcycle shop has rid the touring model of its beefy two-up saddle, large capacity tank, and Vetter-esque bodywork, before building it back up with smaller, dirt track-style tank, classic circular headlight, and a traditional tracker-style tail and side number boards — the right of which boasts a cut-out to accommodate the routing of the boxer’s bespoke two-into-one exhaust. The handling has been upgraded via a front-end plucked from a K75 fit with new progressive springs and a pair of Ohlins shocks in the rear. Other noteworthy details include Mikuni carbs, a Fondseca quick-turn throttle, upgraded brakes, off-road pegs, LSL bars, a Motogadget speedo, and a push-to-start ignition button.
