"You should buy this Crankshaft Bearing 6004"

The engine bearing in a motorcycle is a critical component that supports and allows the smooth rotation of the engine's moving parts, such as the crankshaft and camshaft. It reduces friction between these rotating elements and the engine block, ensuring efficient operation, reducing wear, and prolonging the engine's life. Engine bearings are typically made from durable materials like steel or bronze and are designed to withstand high temperatures and pressures.
