Wiseco 466M06800 68.00mm 2-Stroke Forged Piston Kit Honda CR250R

The Wiseco 466M06800 is a 68.00mm bore, 2-stroke forged piston kit designed for the Honda CR250R (1981–1983). Built to withstand the extreme demands of off-road and motocross riding, this piston is a direct-replacement performance upgrade over the OEM unit.

Key Features:

• High-Silicon Aluminum Alloy Forging: Wiseco's proprietary forging process produces a stronger, lighter piston with superior heat dissipation compared to cast alternatives
• Optimized Skirt Design: Innovative piston skirt geometry reduces friction and improves ring seal, translating to maximum horsepower and torque output
• Complete Kit: Includes piston, rings, wrist pin, and circlips — everything needed for a full piston replacement (unless noted otherwise)
• Oversize Bore: This is an oversize piston; cylinder boring or sleeving to the appropriate bore diameter is required prior to installation
• OEM Reference: Replaces Wiseco piston kit cross-reference 2677CD for the Honda CR250R

Wiseco has been the benchmark for high-performance forged pistons in powersports for decades. The 466M06800 piston kit delivers the reliability and performance demanded by competitive and recreational off-road riders alike.
