Description
Original Piaggio 12x17x13 Piston Pin Bearing
Small end bearings are typically needle bearings located in the upper connecting rod eye (small end), where they hold the piston pin. If the piston pin bearing breaks, it can cause catastrophic engine damage.
Original spare parts allow restoring the scooter to factory condition. The parts are identical to OEM equipment and can be installed without modifications.
Suitable for all Piaggio 50cc 2-stroke engines used across many models from Piaggio, Aprilia, Derbi, Gilera, and Vespa.

What is a Small end bearing?
The small end bearing or piston pin bearing is a needle bearing; the rolling elements used are cylindrically shaped needle rollers. It works similarly to all bearings, reducing friction and increasing the life of the crankshaft and the cylinder.
The small end bearing takes in the piston pin and reduces friction between the piston pin and connecting rod by distributing the load over a larger area.
The small end bearing plays a vital role in the reliability and longevity of the engine, so it is important to replace and lubricate it well each time you reassemble the engine.
