What is a top end bearing used for?

A top end bearing, often found in two-stroke engines, is a crucial component in the cylinder and piston assembly. It helps reduce friction and wear between moving parts in the top end of your engine, ensuring smooth operation.

What does the '21 x 25 x 23.8mm' refer to?

These measurements refer to the bearing's dimensions. The '21mm' is the inner diameter, the '25mm' is the outer diameter, and the '23.8mm' is the width of the bearing. These specific dimensions are important for proper fitment in the engine.

Does this bearing come with any hardware?

This product is for the top end bearing only. Any associated seals, gaskets, or other hardware needed for a complete top-end rebuild are typically sold separately.
