Description
This Vertex top end piston kit features a cast piston meticulously crafted to replicate the original equipment (OE) form, ensuring a precise fit and reliable performance.

This standard size D piston kit is designed for 125cc 2-stroke engines with a 54.00 mm bore size and 53.97 mm piston diameter. The piston rings are made from steel with a nitride coating for superior sealing and wear resistance. Restore your engine's performance with this complete and reliable piston kit from Vertex.
