Motorcycle Drivetrain & Transmission Bearings

Motorcycle drivetrain and transmission play a vital role in delivering engine power to the rear wheel in the most efficient way possible. By modifying and upgrading your gearbox, changing the size of sprockets in the chain drive, you can achieve better acceleration or higher top speed depending on your application, personal preferences, and requirements. Over time, some parts of transmission and drivetrain can show signs of wear resulting in loss of torque and power. Check your clutch pack, sprockets or pulleys, chain or belt regularly. If you hear weird noises coming from wheel bearings, it is time to replace them.

Bearings can have different sizes and forms, but they all carry out the same function – to eliminate friction between any rotating shaft and its housing. A bearing assembly includes races and bearing balls or cylindrical or tapered rollers that prevent metal on metal sliding. Without friction, and with the use of lubricant, the bearing can serve its purpose for years without showing any signs of wear. In case the bearing seal is broken, the grease escapes and dust, sand, and moisture enter the assembly causing damage. Also, the bearing may lose its structural integrity due to increased radial loads or abnormal rotational speed.
