Athena Top End Race Gasket Kit Gas Gas / Yamaha 250cc

The Race Gasket Kit, developed by Athena technicians, serves as a meticulous solution for adjusting cylinder height in racing engines. Tailored for dominant Motocross and Enduro models, the kit is suitable for both 2-stroke and 4-stroke engines. It contains a cylinder head gasket paired with two cylinder base gaskets – one mirroring the OEM component in thickness and an alternative thinner by 0.1 mm, facilitating precise modifications to squish clearance, combustion chamber compression or valve timing.

Features:

  • Specifically designed for the pro, semi-pro and amateur rider who freshens up their engine prior to a race or during mid-season
  • Kit includes a top-of-the line MLSS head gasket and two or more premium-quality base gaskets of different thicknesses to optimize engine compression ratios
  • Gives the rider a choice of using standard gas with stock compression or race gas with a higher compression
  • Kit does not include valve stem seals, rubber parts, shims or other fiber gaskets
