Against the Clock – XTR Pepo BMW R100RS
Imagine this scenario: A bike magazine hands you a box fresh 1978 BMW R100RS and the concept rendering for a fantastic, space-age machine. They place at your disposal a shedload of the finest components from sponsors like Hagon, Akrapovic, Rizoma, and Pirelli; along with a sleek timepiece from Zenith. The Hitch? You have only 7 weeks to prove yourself, your skills and your workshop.
Too much pressure? Not for Pepo Rosell of XTR Pepo. This is the exact challenge set for him by Spanish magazine “Revival of the Machine” earlier this year, and this staggering machine, known as “The Silver Bullet”, is the result.
It’s fair to say that Pepo did not disappoint. The full list of modifications to this machine is overwhelmingly extensive, but at a glance include:
BMW NineT front end conversion and Hagon rear mono shock suspension, A heavily modified frame and subframe, with special lightweight aluminum supports and reinforcements. A super trick single swingarm conversion from a BMW R850 R Guardia Police bike. Upgraded Brembo brakes front and rear and that chunky Pirelli rubber. A race tuned engine rebuild including blueprinting, race cams, high compression pistons, lightened crank, ported heads and electronically controlled multi-map ignition. Fully adjustable Rizoma controls including clip-ons, grips and levers, brake reservoirs, and adjustable rearsets. Breathing upgrades that include upgraded carbs, K&N Filters, and a custom exhaust wearing Akrapovic cans. A full rewire using Motogadget’s M-Unit, a tiny lithium battery and some very trick lighting options at the front and rear. Bespoke aluminum bodywork including a hand-formed fuel tank, front guard, and fairing. A hand carved timber tail section, and a wooden inlay to the tank to house the lavish Zenith timepiece.
