The VERTEX VTK24446A-2 Top End Piston Kit is designed for specified KTM 85 SX and Husqvarna TC 85 applications from 2018 through 2021. This kit features a forged piston manufactured from 2618 aluminum for strength and durability, along with a high-compression design intended to improve power and torque across the RPM range.
The piston skirt is coated with molybdenum disulfide to support faster break-in and increased piston life. The piston is heat treated using a T-5 hardening and tempering cycle, and includes a T-box forging and DLC-coated wrist pin for enhanced strength and performance. The kit includes the piston, rings, pins, circlips, top-end gaskets, and a wrist pin bearing or cam chain where applicable.
