Wiseco 2084M06900 Pro-Lite Piston Kit Bore - 2-Stroke 69.00mm

The Wiseco 2084M06900 Pro-Lite Piston Kit is a complete forged 2-stroke piston kit designed for Arctic Cat and John Deere snowmobiles powered by the Kawasaki 440 engine, featuring a 69.00mm bore diameter. Built from aerospace-grade high-silicon aluminum alloy, this kit delivers the strength, durability, and performance demanded by serious powersports riders.

Key Features:

• Forged aerospace alloy construction — superior strength-to-weight ratio compared to cast OEM pistons for improved reliability under extreme conditions
• CNC-machined piston skirt — computer-engineered cam shape and profile minimizes cylinder wall friction and maximizes power output and service life
• Anti-detonation grooves and precision ring land diameter — eliminates ring blow-by while sustaining peak performance
• Horizontal slot-pin oiling — reduces friction and provides scuff resistance along with a pressure seal groove for maximum ring seal
• Race-ready dome finish — smooth edges promote improved combustion chamber airflow
• Extra lightweight design — contributes to instant throttle response
• Complete kit contents — includes forged piston, high-performance ring(s), alloy wrist pin, and circlips (ring set cross-reference: 2717CD)

Wiseco forges all of their pistons in-house in the USA, controlling the entire manufacturing process from raw bar stock to finished skirt coating. The Pro-Lite line is trusted and chosen by top race teams across Motocross, Supercross, GNCC, and snowmobile racing. Note: Oversize pistons require cylinder sleeving and/or bore and re-nikasil treatment prior to installation.
