Athena Top End Race Gasket Kit Yamaha YZ125

The Race Gasket Kit, conceived by Athena technicians, serves as a precise solution for tuning racing engines. Ideal for a range of Motocross and Enduro motorcycles, this comprehensive gasket set accommodates both 2-stroke and 4-stroke engines. The kit is essential for those aiming to refine squish clearance, perfect combustion chamber compression or fine-tune valve timing. Included in the kit are a cylinder head gasket along with two cylinder base gaskets—one mirroring the OEM part in thickness and another that is thinner by 0.1 mm, providing flexibility and precision for engine adjustments.

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
