Bearings in the rear wheel suspension of a motorcycle are crucial components for the mobility and stability of the rear wheel. They ensure that the swing arm and rear wheel can move with little friction.
Ball or needle bearings are usually used, which have to withstand high loads and speeds. Regular maintenance and lubrication of the bearings is important to prevent wear and extend their service life.
A defective bearing can cause play in the rear wheel suspension and negatively affect driving behaviour. If there are signs of unusual noise or vibration, the bearings should be checked immediately and replaced if necessary.
