Wössner Pistons Top End Needle Bearing

The Wössner Pistons Top End Needle Bearing is a replacement wrist pin bearing, also called a small end bearing or piston pin needle bearing. It is made for two-stroke motorcycle and off-road engines. It supports the wrist pin at the small end of the connecting rod, so the piston can pivot smoothly under load.

Key Features:

• Needle bearing design made for the small end of the connecting rod
• Replacement top end bearing that suits Wössner forged performance piston kits
• Made for smooth, low-friction wrist pin movement
• Precision-made, with the fit and quality Wössner is known for
• Sold under individual part numbers, each in its own bearing dimensions

Fitting a fresh top end bearing when you rebuild the top end helps keep the piston, wrist pin and connecting rod working together as they should. It is a sensible part to replace whenever you service the piston.
