Wiseco 435M05650 Pro-Lite Piston Kit Bore Oversize - 2-Stroke 56.50mm 0.50mm

The Wiseco 435M05650 Pro-Lite 2-Stroke Piston Kit delivers a 56.50mm bore diameter (+0.50mm oversize) for dirt bike engines requiring a precision-fit replacement piston. Engineered, forged, and machined in the USA at Wiseco's facility in Mentor, OH, this kit is built to restore peak performance and reliability to your 2-stroke top end.

Key Features:

• Forged aerospace alloy construction — dedicated forgings provide a superior strength-to-weight ratio for durability under extreme conditions
• CNC machined cam shape and profile — optimized for peak power output and extended service life
• Extra lightweight piston design — reduces reciprocating mass for instant throttle response
• Computer-engineered piston skirt profile — minimizes cylinder wall friction for improved efficiency
• Anti-detonation grooves and precision ring land diameter — eliminates ring blow-by and maximizes combustion seal
• Horizontal slot-pin oiling — reduces friction and provides scuff resistance
• Improved tensile strength — forged material optimizes strength and service life over cast alternatives
• Complete kit — includes high-quality piston ring(s), wrist pin, and circlips; only Wiseco replacement ring sets should be used on Wiseco pistons

The Pro-Lite line is the result of over 80 years of Wiseco 2-stroke piston expertise, and is trusted and chosen by top race teams across Supercross, Motocross, and GNCC competition. Whether you're rebuilding a trail bike or a dedicated race machine, the Wiseco Pro-Lite kit provides a factory-quality top end rebuild in one package.

Kit Includes: Forged piston (56.50mm / +0.50mm oversize), piston ring(s), wrist pin, circlips
