Wiseco 2460M08500 Pro-Lite Forged Piston Kit Bore - 2-Stroke 85.00mm

The Wiseco 2460M08500 Pro-Lite Piston Kit is a high-performance forged 2-stroke piston kit engineered for 85.00mm bore applications. Built on decades of motorsport engineering experience, the Pro-Lite line is Wiseco's flagship 2-stroke piston — trusted by top race teams and recreational riders alike for its combination of durability, performance, and value.

Each piston is forged from high-silicon, low-expansion aluminum alloy, delivering superior strength, reduced weight, improved heat transfer, and extended service life compared to cast OEM alternatives. Wiseco forges all pistons in-house at their U.S. facility using proprietary tooling, allowing complete control over every stage of manufacturing — from raw material to finished skirt coating.

The Pro-Lite piston features a race-ready dome finish with smooth edges for optimized combustion flow, and dedicated forgings provide a superior strength-to-weight ratio. A horizontal slot-pin oiling design reduces friction and improves scuff resistance, while the pressure seal groove maximizes ring seal for consistent power delivery. CNC machining ensures an optimal cam shape and profile for peak output and long service life.
