Athena Top End Race Gasket Kit Yamaha WR450F / YZ450F / YZ450FX
The Race Gasket Kit emerges as a critical solution for motocross and enduro enthusiasts requiring precision engine tuning. Developed by Athena's skilled technicians, this kit suits the most widely used 2-stroke and 4-stroke engines, providing a vital tool for adjusting cylinder height to refine squish clearance, enhance combustion chamber compression or improve valve timing. The package comprises a cylinder head gasket and a pair of cylinder base gaskets – one mirrors the original equipment manufacturer's specifications, while the other offers a slender profile, reduced by a mere 0.1 mm, for those subtle yet impactful modifications.
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
