This genuine OEM piston kit is a comprehensive top-end rebuild solution designed to restore the performance and compression of your 300cc two-stroke engine. It includes the piston, rings, wrist pin, circlips, needle bearing, and all necessary gaskets for a complete top-end service. As an original equipment manufacturer part, it ensures perfect fitment and adheres to the strict tolerances required for high-performance riding.

This kit is compatible with a wide range of 300cc TPI and fuel-injected models. It fits KTM 300 EXC, EXC Six Days, XC-W, and XC models from 2018 to 2023. It is also designed for Husqvarna TE 300i, TX 300i, and Heritage models (2018-2023), as well as GasGas EC 300 and EX 300 models from 2021 to 2023.

The Gr. II (Size B) piston is specifically sized for cylinders that have seen some use, providing a tighter seal than the standard Size A piston. The piston features a high-quality coating to reduce friction and extend the life of the cylinder wall. Using an OEM kit guarantees that the materials used, from the gaskets to the needle bearing, meet the factory specifications for heat resistance and durability.

When installing this kit, ensure the cylinder bore is thoroughly cleaned and inspected for any scoring or damage. It is recommended to follow the manufacturer's torque specifications for the cylinder head and base bolts to prevent leaks. Regular top-end maintenance is crucial for maintaining the power delivery and reliability of your motorcycle, especially in demanding off-road conditions.
