Piston Kit Gr. II (Size B) for KTM 65 SX/TC/MC 2009-2023 - 46230007110 II

This is a complete OEM Piston Kit Gr. II (Size B) designed for 65cc two-stroke engines. It includes the piston, rings, wrist pin, circlips, needle bearing, and a full set of top-end gaskets required for a professional engine rebuild. As an original equipment manufacturer part, it ensures perfect fitment and maintains the high performance of your motorcycle's engine.

This kit is compatible with KTM 65 SX models from 2009 to 2023, KTM 65 SXS from 2012 to 2015, and KTM 65 XC (2009). It also fits Husqvarna TC 65 models from 2017 to 2023 and GasGas MC 65 models from 2021 to 2023. Please verify your cylinder size before ordering to ensure the Gr. II (Size B) piston is the correct match for your engine's wear specifications.

The Gr. II (Size B) piston is slightly larger than the standard Size A, making it ideal for cylinders that have seen some use and require a tighter tolerance for optimal compression. The included high-quality gaskets and O-rings provide a reliable seal to prevent leaks and maintain peak power output.

For best results, we recommend checking the cylinder bore for any scoring or damage before installation. Always use a torque wrench to tighten cylinder head bolts to the manufacturer's specifications and ensure all components are properly lubricated with two-stroke oil during assembly.
