Athena Top End Race Gasket Kit Honda CRF250R / CRF250RX

The Race Gasket Kit, expertly designed by Athena technicians, serves as an essential tool for adjusting cylinder height during the fine-tuning of racing engines. Ideal for prominent Motocross and Enduro models, it accommodates both 2T and 4T engines, ensuring precise squish clearance, optimal combustion chamber compression and refined valve timing. The kit provides a cylinder head gasket alongside two cylinder base gaskets. One gasket matches the OEM part's thickness, while the other offers a reduced thickness of 0.1 mm, granting mechanics the flexibility to meet exacting engine specifications.

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
