Vertex Race Evo 2-Stroke Piston Kit KTM / Husqvarna / Gas Gas 85cc

Engineered for peak track performance, the Vertex Race Evolution Series Top-End Piston Kit displays a design tailored for higher revs and improved throttle response. Constructed from gravity-cast aluminum alloy with 18% silicone content, the piston is subjected to a T-5 heat treatment and tempering, ensuring it can withstand demanding racing conditions. It features a race-specific crown and skirt profile, a reduced top land, and an advanced Molybdenum Disulfide skirt coating that minimizes friction, promotes rapid break-in, and enhances engine longevity. Accompanied by nitrided steel rings for optimal sealing at high RPM, the kit provides all necessary components for a high-performance top-end rebuild.

Features:

• Race Evolution Series geometry featuring a reduced top land and optimized crown profile for reduced drag and faster revving
• Ultra-durable nitrided steel piston rings designed for maximum compression sealing under race conditions
• Heat-treated piston with T-5 hardening and tempering process for superior structural integrity
• High-tech Molybdenum Disulfide coating on the piston skirt for rapid break-in and reduced friction
• Premium gravity-cast aluminum alloy construction with 18% silicone content for high strength and low thermal expansion
• Complete top-end kit includes Race Evolution piston, nitrided rings, wrist pin, circlips, top-end gaskets, and wrist pin bearing
