Product information

If you wish to know the exact brand of bearings before ordering this item, please do not hesitate to contact us.
The main bearings are located inside the crankcase and support the crankshaft. During the use of the motorcycle, the bearings undergo friction and wear and can deteriorate over time. If they are not replaced along with the connecting rod, they may not be able to support the new connecting rod properly, causing engine running problems.
Symptoms of worn main bearings can vary, but there are a few signs to look out for:
1. Engine noise may become louder and a clicking noise may be heard when idling, especially when the bike is cold.
2. Vibrations: Bad main bearings can cause abnormal vibrations throughout the engine.
