Description
Description
This genuine OEM Piston Kit Group II (Size B) is designed to restore engine compression and performance in high-performance 85cc two-stroke engines. As an original equipment manufacturer part, it ensures precise tolerances and reliable operation under demanding racing conditions. The kit includes the piston, piston ring, wrist pin, and circlips for a complete top-end refresh.
This piston kit is compatible with a wide range of 85cc models, including the KTM 85 SX (2003-2025), KTM 85 SXS (2013-2015), and KTM 85 XC (2009). It also fits Husqvarna TC 85 models from 2014 to 2025 and GasGas MC 85 models from 2021 to 2025. It is suitable for both 17/14 and 19/16 wheel configurations across these brands.
The piston features a specialized coating to reduce friction and heat, extending the life of the cylinder bore. The Group II (Size B) designation is specifically intended for cylinders that have experienced slight wear or require a marginally larger diameter than the standard Size A to maintain optimal clearance and power output.
Regular piston replacement is critical for maintaining the power and reliability of your motocross bike. We recommend following the manufacturer's service intervals and ensuring the cylinder is properly measured and cleaned before installation. Always use fresh gaskets and high-quality two-stroke oil during the initial break-in period.
