Wiseco WK1016 Kawasaki 650 Pro-Lite 2-Stroke Piston Top End Kit 76mm

The Wiseco WK1016 is a complete Pro-Lite top end piston kit designed for Kawasaki 650 personal watercraft engines. Built to replace worn components and restore peak performance, this kit features a 76.00mm standard bore forged piston engineered specifically for the 2-stroke Kawasaki 650 twin-cylinder PWC engine.

Wiseco 2-stroke pistons are forged from high-silicon aluminum bar stock, delivering superior tensile strength, reduced thermal expansion at high operating temperatures, and an optimized strength-to-weight ratio compared to cast alternatives. Each piston is dedicated to its specific engine application—not a generic fit—ensuring precise dimensional accuracy and long service life.

Kit Includes:

• High-performance forged Pro-Lite piston(s)
• Wiseco piston ring(s)
• Wrist pin(s)
• Circlips
• Top-end gasket kit for one complete engine

Key Features:

• Forged from high-silicon aluminum for superior strength and reduced weight
• Pro-Lite design with dedicated forgings and lightening operations for optimized strength-to-weight ratio
• Diamond-turned CNC finish ensures consistent sizing and compatibility with cast iron, chrome, Nikasil, and boron composite cylinder bores
• Standard bore size: 76.00mm
• Engineered, forged, and machined in the USA in Mentor, OH
• Wiseco rings are included and must be used exclusively with Wiseco pistons — ring types are not interchangeable

Wiseco's legacy in 2-stroke piston manufacturing spans over 80 years, making the WK1016 a trusted choice for both performance riders and recreational PWC enthusiasts seeking a reliable top end rebuild.
