Wiseco 2366M06660 Pro-Lite Piston Kit Bore Standard - 2-Stroke 66.60mm

The Wiseco 2366M06660 Pro-Lite Piston Kit is a complete 2-stroke top-end rebuild kit featuring a standard 66.60mm bore forged piston. Built in the USA, Wiseco forges all pistons in-house and produces their own forge tooling, allowing full control of the manufacturing process from raw material to finished part.

The Pro-Lite is Wiseco's cornerstone 2-stroke forged piston — the result of decades of experience incorporating the latest in 2-stroke piston manufacturing and design. It is engineered for all-purpose 2-stroke riding, delivering a proven balance of value, reliability, and performance.

Key Features:

• Forged from high-silicon aerospace aluminum alloy for superior strength-to-weight ratio and maximum dependability
• CNC machined for optimal cam shape and profile for peak power output and long service life
• Race-ready dome finish with smooth edges for improved combustion chamber flow
• Innovative forging design and piston skirt geometry maximize horsepower and torque
• Horizontal slot-pin oiling reduces friction and provides scuff resistance
• Pressure seal groove design for maximum ring seal
• Significantly stronger and more durable than OEM cast pistons

Kit Includes:

• Forged Pro-Lite piston (66.60mm standard bore)
• Piston rings
• Wrist pin
• Circlips

Note: This kit is sized for a standard bore cylinder. Measure your cylinder before ordering. Oversize pistons require cylinder re-sleeving or reboring.
