What is a top-end bearing used for?

A top-end bearing, often referred to as a crank bearing or rod bearing in two-stroke engines, is essential for the smooth rotation of the crankshaft. It supports the crankshaft and reduces friction, which is critical for engine performance and longevity, especially in high-revving two-stroke applications.

What does the '20 x 26 x 23.8mm' measurement refer to?

These measurements refer to the bearing's dimensions. The first number (20mm) is the inner diameter, the second (26mm) is the outer diameter, and the third (23.8mm) is the width of the bearing. These precise dimensions ensure it fits correctly within the engine case and on the crankshaft.

Does this bearing come with any hardware or seals?

This product is for the Wiseco top-end bearing only. Any necessary seals, gaskets, or other hardware required for installation would typically need to be purchased separately.
