Wiseco 2377M06450 Pro-Lite Piston Kit Bore - 2-Stroke 64.50mm

The Wiseco 2377M06450 Pro-Lite 2-Stroke Piston Kit delivers a 64.50mm (2.539 in.) bore forged piston engineered for all-purpose 2-stroke powersports performance. Built on decades of 2-stroke piston development, the Pro-Lite line combines proven race-inspired design with reliable everyday rideability.

Each piston is forged from high-silicon aerospace aluminum alloy using a dedicated forging designed specifically for superior strength-to-weight optimization. CNC machining ensures optimal cam shape and skirt profile for peak power output and extended service life. A horizontal slot-pin oiling system reduces friction and provides scuff resistance, while the pressure seal groove promotes maximum ring seal for consistent compression.
