Athena Top End Race Gasket Kit Yamaha WR450F / YZ450F / YZ450FX

Athena has crafted the Race Gasket Kit for motocross and enduro enthusiasts seeking to fine-tune their racing engines. Precision adjustments to the cylinder height are crucial for optimizing squish clearance, compression and valve timing. The product includes a high-quality cylinder head gasket alongside two carefully designed cylinder base gaskets. One gasket matches the original equipment manufacturer's thickness, while the other offers a slimmed-down alternative, reduced by 0.1 mm, to allow for meticulous engine modifications. This kit is engineered to cater to both 2-stroke and 4-stroke engines, accommodating the most frequently raced engine types.

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
