The Wiseco 2373M07250 Pro-Lite Piston Kit is a performance-forged 2-stroke piston kit featuring a 72.50mm bore diameter (.020" / 0.50mm oversize). Built on decades of racing heritage, the Pro-Lite line delivers the ideal balance of performance, reliability, and value for 2-stroke powersports engines.

Key Features:

• Forged high-silicon aerospace aluminum alloy construction for superior strength-to-weight ratio, reduced expansion, and improved heat transfer
• CNC machined to an optimized cam shape and skirt profile for peak power output and extended service life
• Horizontal slot-pin oiling reduces friction and provides scuff resistance
• Pressure seal groove maximizes ring seal for consistent performance
• Anti-detonation grooves and precisely dimensioned ring land diameter eliminate ring blow-by
• Extra lightweight design engineered for instant throttle response
• Race-proven designs trusted by top race teams in Supercross, Motocross, and GNCC competition
• Complete kit includes: forged piston, rings, wrist pin, and circlips

Oversize pistons require cylinder boring or sleeving to the correct diameter prior to installation. Always measure your cylinder bore before ordering to confirm proper clearance. Wiseco forges all pistons in-house in the U.S.A., maintaining strict control over every stage of the manufacturing process from raw material to finished skirt coating.
