The Wiseco 813M08050 is a Pro-Lite series 2-stroke forged piston kit engineered specifically for Kawasaki 750 personal watercraft engines. With an 80.50mm bore diameter (+0.50mm oversize) and wrist pin diameter of 20mm, this kit is designed for engine rebuilds or performance upgrades on 1992–1995 Kawasaki 750 PWC models including the JS750 750SX, JH750 750SS, JH750 750ZXi, JH750 Super Sport XI, JH750 XiR, JT750 ST, and JT750 STS.

Key Features:

• Forged 4032 Aluminum Alloy: Precision-forged in the USA for superior tensile strength, heat resistance, and detonation control compared to cast pistons
• Pro-Lite Series Design: Dedicated forgings with CNC lightening operations deliver an optimized strength-to-weight ratio for quicker revs and long-term reliability
• Optimized Skirt Profile: Contoured piston skirts improve cylinder sealing, reduce friction, and sharpen engine response
• Compatible with Multiple Cylinder Types: Diamond-turned finish allows confident installation in cast iron, chrome, Nikasil, and boron composite cylinder bores
• Complete Kit: Includes forged piston, piston ring(s), wrist pin, and circlips — everything needed for a single-cylinder rebuild
• Made in the USA: Engineered, forged, and machined at Wiseco's facility in Mentor, OH
