Wiseco 2399M08200 Pro-Lite Forged Piston Kit Bore Oversize - 2-Stroke 82.00mm 1.00mm

The Wiseco 2399M08200 Pro-Lite Piston Kit delivers a high-performance, forged replacement piston at an 82.00mm bore diameter with a +1.00mm oversize specification. Engineered for demanding 2-stroke powersports applications, the Pro-Lite line represents decades of Wiseco forging expertise built into a piston designed for all-purpose performance and reliability.

Each Pro-Lite piston is forged from high-silicon, low-expansion aluminum alloy, offering superior strength, reduced weight, improved heat transfer, and longer service life compared to cast alternatives. The innovative piston skirt profile is computer-engineered to minimize cylinder wall friction while maximizing horsepower and torque output.

Key Features:

• Forged high-silicon aluminum alloy construction for maximum strength and durability
• 82.00mm bore diameter — +1.00mm oversize (cylinder boring or sleeving required)
• Computer-engineered piston skirt profile for minimal friction and optimal cam shape
• Anti-detonation grooves and precision ring land diameter to eliminate ring blow-by
• Horizontal slot-pin oiling reduces friction and provides scuff resistance
• Pressure seal groove for maximum ring seal and sustained power
• Extra lightweight design for instant throttle response
• Complete kit includes: forged piston, high-performance rings, wrist pin, and circlips

Important: This is an oversize piston. Cylinder boring or sleeving is required prior to installation. Measure your cylinder bore carefully to confirm proper clearance before ordering.
