The Wiseco 564M05500 Pro-Lite piston kit delivers reliable performance for 2-stroke dirt bike engines requiring a 55.00mm bore. This is a 1.00mm oversize piston designed for 125cc displacement engines with a 54.50mm stroke length, commonly used in Honda CR125R applications from 1988-1989.

Key Features:

• Forged from 4032 aluminum alloy for maximum strength and heat resistance
• Pro-Lite forged design incorporating decades of 2-stroke piston manufacturing experience
• Actual piston diameter of 54.94mm for optimal bore fit
• Complete kit includes piston, rings, wrist pin, and circlips
• Optimized forging for strength with lightning operations for enhanced throttle response
• Non-coated skirt design suitable for various cylinder bore compositions

The Pro-Lite series offers great value, reliability, and performance as the staple of 2-stroke pistons. This oversize piston requires cylinder sleeving or boring to accept the larger diameter. Wiseco pistons are precision-machined using CNC equipment and are compatible with cast iron, chrome, Nikasil, and boron composite cylinder bores.
