To restore a worn crankshaft or prepare for a refurbishment after intensive use, the ALL BALLS bearing and seal kit provides the essential components for a clean and safe reconditioning. Designed for motocross use, this kit includes bearings and seals compatible with original specifications, ensuring proper sealing and controlled play at the engine bearings.
Replacing the bearings and seals of the crankshaft restores rotational smoothness, reduces oil leaks at the casings, and ensures more consistent engine behavior. This kit is suitable for routine maintenance and refurbishment on motocross bikes, including recent models such as the KTM 300 SX (2025), GAS GAS EC 300 (2024), or HUSQVARNA TC 250 (2024). Always check compatibility with your model before proceeding.
