What is a top end bearing and why is it important for a two-stroke engine?

A top end bearing is a crucial component in the upper part of your engine, typically supporting the connecting rod where it meets the crankshaft. For two-stroke engines, it's vital for smooth rotation and reducing friction, which is essential for performance and engine life.

What does the '18 x 22 x 23.5mm' measurement refer to?

These measurements refer to the bearing's dimensions. The first number (18mm) is the inner diameter, the second (22mm) is the outer diameter, and the third (23.5mm) is the width of the bearing. These specific dimensions ensure it fits correctly in the intended engine components.

Does this bearing come with any hardware or seals?

This product is for the top end bearing only. Any necessary seals or additional hardware for your specific engine rebuild should be sourced separately based on your vehicle's service manual.
