Description
Description
This genuine OEM countershaft repair kit is designed to restore the sealing integrity of your motorcycle's transmission output. It includes all the necessary components to replace worn seals and spacers around the front sprocket area, preventing oil leaks and protecting the internal gearbox components. Using original parts ensures a precise fit and reliable performance under demanding off-road conditions.
This kit is compatible with a wide range of 250cc and 300cc two-stroke models from 2017 to 2023. It fits KTM 250/300 EXC, EXC TPI, XC, and XC-W models, as well as Husqvarna TE 250/300, TE 250i/300i, and TX 300. Additionally, it is suitable for GasGas EC 250/300 and EX 250/300 models. This includes specialized editions like the Six Days, Erzbergrodeo, Heritage, and Rockstar editions.
The kit features a high-quality shaft seal, O-ring, spacer bushing, washer, and mounting bolt. These components work together to provide a tight seal against the countershaft, even when subjected to the high heat and debris common in motocross and enduro riding. Replacing these parts as a set is recommended whenever you notice oil weeping from behind the front sprocket.
Installation is straightforward and can be performed during a routine sprocket change. Ensure the countershaft surface is clean and free of burrs before installing the new spacer and seal to prevent premature wear. Applying a small amount of grease to the seal lip will help ensure a smooth initial break-in and a long-lasting seal.
