Vertex Top End Piston Kit 44.45mm VTK22860B — Kawasaki / Suzuki KX65 / RM65 2000-2024

Product Description

Refresh your 65cc 2-stroke engine with the Vertex VTK22860B Cast Replica Top End Piston Kit. This kit is engineered as a direct replacement for your original equipment, utilizing a gravity-cast aluminum alloy with 18% silicone content to ensure stable thermal expansion and structural reliability. The piston undergoes a T-5 hardening and tempering cycle to maintain integrity under engine load.

To optimize performance and longevity, the piston skirt is finished with a Molybdenum Disulphite coating, which aids in a quick break-in period and reduces internal friction. This complete kit provides all necessary components for a top-end refresh, including the piston, rings, wrist pin, circlips, top-end gaskets, and the wrist pin bearing.

Frequently Asked Questions

Q: What is the benefit of the 18% silicone content in the cast piston?
A: The high silicone content reduces the piston's thermal expansion rate, allowing for tighter clearances between the piston and the cylinder wall, which results in quieter operation and improved ring seal.

Q: Does this kit include the top-end gaskets?
A: Yes, this kit includes a full top-end gasket set along with the piston, rings, pin, clips, and wrist pin bearing, making it a complete solution for a standard top-end service.

Expert Pro-Tip: Always ensure your cylinder bore is within service limits and de-glazed before installing a new piston. A clean, properly prepared surface is essential for the new rings to seat correctly during the break-in process.
