Whether you are performing a top-end refresh or a full engine rebuild, this precision-ground bearing provides the stable support needed to prevent premature wrist pin wear and engine vibration.
This bearing is a standard fit for many 50cc 2-Stroke engines using a 10mm wrist pin:
Mechanic's Note: The wrist pin bearing is often the most overlooked part of a top-end rebuild.
Safety Warning: A worn bearing can lead to wrist pin "slap" which eventually destroys both the piston and the rod.
Pro Tip: Always soak your new bearing in 2-Stroke Oil for several minutes before installation to ensure it isn't "dry" during the critical first few seconds of engine startup!
