Piston Kit Gr. I (Size A) for KTM 65 SX, Husqvarna TC 65 2009-2023 - 46230007110 I

This genuine OEM Piston Kit Gr. I (Size A) is a comprehensive top-end rebuild solution designed for 65cc engines. It includes the piston, rings, wrist pin, circlips, needle bearing, and a complete set of cylinder base gaskets to ensure a perfect seal and optimal compression. Using original parts guarantees the precise tolerances required for high-performance two-stroke racing engines.

This kit is compatible with a wide range of models, including the KTM 65 SX from 2009 to 2023 and the KTM 65 XC (2009). It also fits Husqvarna TC 65 models from 2017 to 2023 and GasGas MC 65 models from 2021 to 2023. Additionally, it serves as a direct replacement for KTM 65 SXS models produced between 2012 and 2015.

The Gr. I (Size A) designation indicates the standard bore size, making it ideal for cylinders that are within original factory specifications. The included gaskets of varying thicknesses allow for precise squish gap adjustment, which is critical for maximizing power output and engine longevity. Each component is manufactured to withstand the high RPMs and heat typical of competitive motocross environments.

For the best results, we recommend measuring your cylinder bore before installation to confirm that a Size A piston is the correct fit. Always lubricate the piston and needle bearing with high-quality two-stroke oil during assembly. Proper break-in procedures should be followed to ensure the rings seat correctly against the cylinder wall.
