Wiseco 629M05650 Pro-Lite Piston Kit Bore Oversize - 2-Stroke 56.50mm 0.50mm

The Wiseco 629M05650 Pro-Lite Piston Kit is a forged 2-stroke dirt bike piston assembly machined to a 56.50 mm bore (+0.50 mm oversize). Built on decades of 2-stroke piston engineering experience, the Pro-Lite line delivers a reliable balance of performance, durability, and value for all-purpose off-road and motocross riding.

Key Features:

• Forged aerospace-grade alloy construction for a superior strength-to-weight ratio over cast alternatives
• CNC-machined cam shape and skirt profile engineered to minimize cylinder wall friction and maximize power delivery
• Horizontal slot-pin oiling reduces friction and provides scuff resistance for extended service life
• Anti-detonation grooves and precision ring land diameter eliminate ring blow-by while maximizing engine performance
• Lightweight forging promotes instant throttle response and maximum torque output
• Forged and machined in the USA at Wiseco's state-of-the-art facility in Mentor, OH

Kit Includes:

• Pro-Lite forged piston (56.50 mm bore)
• High-performance piston ring(s)
• Circlips
• Note: Wrist pin is not included with 2-stroke kits unless specifically noted. Only genuine Wiseco replacement ring sets are compatible with Wiseco pistons.
• Note: Oversize bore requires professional cylinder boring or sleeving. Top-end bearing is not included.

Race-proven and trusted by top teams across Supercross, Motocross, and GNCC competition, the Wiseco Pro-Lite is the benchmark forged 2-stroke piston for dirt bike riders who demand reliability and performance from every rebuild.
