Vertex Top End Piston Kit, 53.93 mm for Honda CR125R (VTK22995B)

Restore reliable top-end performance with the VERTEX VTK22995B Top End Piston Kit for Honda CR125R motorcycles. Designed as a cast original-equipment replacement piston, this kit provides the key components needed for a complete piston replacement while supporting dependable operation and efficient engine break-in.
The piston is manufactured from gravity-cast aluminum alloy with an 18% silicone content for a balance of strength, wear resistance, and dimensional stability. A T-5 heat-treating and tempering cycle improves material performance, while the piston skirt features a high-tech molybdenum disulfide coating. This low-friction coating helps promote faster break-in and may contribute to extended piston life when installed and maintained according to the motorcycle manufacturer’s specifications.
The VERTEX VTK22995B kit includes the piston, piston rings, wrist pin, circlips, top-end gaskets, and wrist pin bearing. Supplied components help simplify the rebuild process and support a thorough top-end service without requiring separate sourcing of essential replacement parts. Verify engine model, fitment, and required installation clearances before assembly.
