Revenge’s motor is a stock-size 80-incher, but with performance modifications done by RBC. Internally, a set of Wiseco pistons compresses the mixture from the Keihin carb which is mounted in front of the engine and breathes through a RBC air cleaner. The Moto Guzzi-style engine placement prompted Charly to design an unusually crafty handmade exhaust. The pipes have more twists and turns than a road over the Alps before dumping out over and under what appears to be a swingarm. But that’s not what makes this bike special; it’s RBC’s mating of the twisted Evo to a BMW R/75 4-speed transmission and shaft-drive. Beautifully integrated and looking like it was made to be connected to an Evo in the first place, Charly did a fine job of engineering these Bavarian pieces into his design. The unusual kick-only setup now starts by pushing the left-side lever down and away from the engine.
