Description
This genuine OEM grooved ball bearing (16003 C4 J1) is a critical component for your motorcycle's transmission system. It is designed to support the main shaft and countershaft, ensuring smooth gear transitions and reducing internal friction. As an original equipment manufacturer part, it meets the exact factory specifications required for high-performance engines.
This bearing fits an extensive range of models including the KTM 125 SX, 150 XC-W, 250 EXC-F, and 640 LC4 series from 1995 to 2026. It is also compatible with Husqvarna TC 125, TE 150, and TX 125 models, as well as GasGas MC 125 and EC 125 bikes. Whether you ride a vintage LC4 or a modern 2026 two-stroke, this part provides the reliability needed for demanding off-road and street conditions.
The C4 clearance rating indicates that this bearing is engineered to handle high speeds and thermal expansion within the gearbox. Its high-quality steel construction offers superior durability and resistance to wear under heavy loads. Replacing worn bearings is essential to prevent transmission failure and maintain the longevity of your engine's internal components.
Professional installation is recommended when splitting the crankcase to access the transmission shafts. Ensure the bearing seats are clean and properly lubricated before pressing the new unit into place. Regular oil changes will help keep this bearing functioning optimally by removing metal shavings and contaminants from the transmission fluid.
