What It Took To Update The Yamaha TZ250
This particular 5KE4 Yamaha TZ250 machine has been treated to the full 2006 SJK Engine Power Up Kit, developed for the near-mythical eponymous Japanese engineering workshops. Highlights of this kit include: N810 cylinders, N800 pistons, N800 exhausts, kit loom with selector switch, plus original HRC detonation counter and data logger. The existing, and still original, crankcase was reworked at the Yamaha Race Factory, for the MotoGP wildcard race. Our bike was a front-runner in the all-Japan GP250 class, wild-carding at MotoGP. We are honoured that this bike has been accepted into the official global Yamaha Racing Heritage Club (YRHC).
