Wiseco WK1061 Pro-Lite Complete Piston Kit 81.00mm +1.00mm Oversize Kawasaki 750 Twin

The Wiseco WK1061 is a complete Pro-Lite forged piston kit designed as a +1.00mm oversize (81.00mm bore) replacement for Kawasaki 750cc twin-cylinder 2-stroke engines. Purpose-built for reliable top-end rebuilds and performance applications, this kit delivers everything needed to complete the job in a single purchase.

What's Included:

• Forged Pro-Lite piston(s)
• High-performance piston ring set
• Alloy wrist pin
• Circlips
• Top-end gasket kit

Key Features:

• Forged Aerospace Alloy Construction — Pistons are precision-forged from aerospace-grade aluminum alloy, delivering a superior strength-to-weight ratio compared to cast alternatives
• Pro-Lite CNC Machining — Each piston is CNC-machined for optimal cam shape and skirt profile, maximizing horsepower output and extending service life
• Horizontal Slot-Pin Oiling — Reduces friction and provides scuff resistance, combined with a pressure seal groove for maximum ring seal integrity
• Anti-Detonation Grooves — Ring land geometry eliminates ring blow-by while sustaining peak performance under high-load conditions
• Compatible Cylinder Bores — Engineered for use in cast iron, chrome, Nikasil, and boron composite cylinder bores
• Oversize Availability — +1.00mm oversize designation allows resleeved or bored cylinders to be restored to proper tolerances
• Race-Proven Design — Developed from designs trusted by top race teams across motocross, watercraft, and powersports competition
• Made in the USA — Forged and machined domestically at Wiseco's manufacturing facility

Important: Wiseco pistons must be fitted exclusively with Wiseco rings — ring types are not interchangeable between series (e.g., CD rings are not compatible with LC or TD configurations). Oversize bore selections require cylinder boring and Nikasil replating or installation of a new cylinder sleeve.

The WK1061 is part of Wiseco's industry-leading Pro-Lite piston lineup, engineered to provide consistent, durable performance for both competitive racers and recreational riders rebuilding their 2-stroke powerplants.
