Vertex Top End Piston Kit VTK23430CD — KTM/Husqvarna/Gas Gas 65cc 2009-2023 (44.97mm)

Product Description

Keep your youth rider's 65cc machine performing at its peak with the Vertex VTK23430CD Top End Piston Kit. This comprehensive, all-in-one kit is designed for a wide range of KTM, Husqvarna, and Gas Gas 65cc 2-stroke models, streamlining your top-end rebuild process by including a high-quality cast replica piston along with all necessary gaskets and the essential wrist pin bearing.

Vertex cast pistons are engineered using an 18% silicone-content gravity-cast aluminum alloy, which provides exceptional dimensional stability under the rigorous heat cycles of 2-stroke operation. The factory-applied Molybdenum Disulphite (MoS2) skirt coating significantly reduces friction and accelerates the break-in process, ensuring your engine runs smoothly and reliably from the first ride.

Frequently Asked Questions

Q: Why is it important to replace the wrist pin bearing?
A: The wrist pin bearing is a high-load, high-wear component in 2-stroke engines. Replacing it during every piston change is a crucial safety step to prevent catastrophic bearing failure that can damage your newly rebuilt piston and cylinder.

Expert Pro-Tip: Always check your ring end gap in the cylinder before final assembly. This simple measurement ensures optimal compression and prevents ring binding as the engine reaches operating temperature.
