I built this Yamaha last year I won a couple of am races on it and now selling to help pay for a RZR 4 1000. Here is the list of goodies: Engine-All bearings are replaced with original size, sent the head off to a guy named Derek Harris in San Antonio who port and polished the head, e is also the guy who developed MR12 at the VP headquarters there. The cams are degreed and it has a competition head gasket. Suspension- 20mm Ohlins in the front forks and a Ohlins TTX GP rear shock! Computer- A basic power commander V with a quickshifter and the ECU has been flashed to unleash a lot of the factory restrictions. 520 chain and sprockets, lip ons and driven triple clamp. Brand new brembo master cylinder, tainless steel brake lines and galfer wave rotors, hich are set on a pair of Marchesini mags that are 16.5's. I have two sets of Pireli's for them plus the factory wheels which also have street tire Pireli's.Vortex Rear sets, nd Full Yosimura R-55 race Exhaust! The body work i are Armor Bodies with a Yamaha factory paint scheme. This bike is mapped on MR12 race fuel in El paso Tx by Fast by Few! Dynoed 120HP!!!! It is a tight motor and has never been raced after the rebuild this last spring!!
