VERTEX VTK24447AB-1 Top End Piston Kit

The VERTEX VTK24447AB-1 Top End Piston Kit is designed for specified 65cc two-stroke applications, providing a complete top-end replacement package. The kit includes a piston, rings, pins, circlips, top-end gaskets, and a wrist pin bearing or cam chain where applicable.

Forged pistons use 2618 aluminum for strength and durability, while forged high-compression designs help improve power and torque across the RPM range. The piston skirts feature a molybdenum disulfide coating to support faster break-in and extended piston life. Pistons are heat treated using a T-5 hardening and tempering cycle, and all rings are OEM replacements.

The VERTEX VTK24447AB-1 fits the 2024 and 2025 Gas-Gas MC 65, 2024 and 2025 KTM 65 SX, and 2024 and 2025 Husqvarna TC 65.
