Wiseco 2346M06825 Pro-Lite Piston Kit Bore Oversize - 2-Stroke 68.25mm 020

The Wiseco 2346M06825 Pro-Lite Piston Kit is a +.020 oversize (68.25mm bore) forged 2-stroke piston kit designed for the Polaris 650 Indy engine family. Note: This oversize piston requires cylinder boring or sleeving before installation.

Key Features:

• Forged aerospace-quality alloy construction — dedicated forgings deliver a superior strength-to-weight ratio compared to cast OEM pistons, resisting impact and fatigue under high-performance conditions
• CNC-machined cam shape and profile — optimized piston skirt geometry for peak power output and extended service life
• Race-ready dome finish — smooth edges promote improved combustion flow for maximum horsepower and torque
• Horizontal slot-pin oiling — reduces friction and provides scuff resistance, with a pressure seal groove for maximum ring seal
• Precision-machined wrist pin included — manufactured to tight tolerances for quiet, reliable operation
• Complete kit contents — includes forged piston, high-performance alloy rings, wrist pin, and circlips; everything needed for a full top-end rebuild
• +.020 oversize bore — 68.25mm finished bore diameter; cylinder boring required prior to installation

Wiseco forges all of their pistons in-house in the USA and produces their own forge tooling, allowing complete control of the manufacturing process from raw material to finished part. The Pro-Lite line represents decades of 2-stroke piston development and is trusted by top race teams across all forms of motorsport competition.
