Wiseco 2345M07225 Pro-Lite Forged Piston Kit Bore - 2-Stroke 72.25mm

The Wiseco 2345M07225 Pro-Lite Piston Kit is a complete forged 2-stroke piston kit offering a 72.25mm bore diameter (0.25mm oversize). Engineered, forged, and machined entirely in the USA, this kit delivers the performance and durability that Wiseco has built its reputation on across decades of powersports racing and recreational riding.

Wiseco Pro-Lite pistons are constructed from high-silicon, low-expansion aluminum alloy, providing superior strength, reduced weight, improved heat transfer, and extended service life compared to OEM cast pistons. Each piston receives a diamond-turned CNC finish for precise sizing with zero variation, ensuring proper cylinder fitment and consistent performance.

Kit Includes:

• One (1) Pro-Lite forged piston – 72.25mm bore
• CD Series ring(s) – alloy steel, Ferrox-coated and chrome-plated with internal notch design
• High-quality alloy wrist pin
• Circlips

Key Features:

• Dedicated forging design optimized for superior strength-to-weight ratio
• Horizontal slot-pin oiling reduces friction and provides scuff resistance
• Pressure seal groove for maximum ring seal and combustion efficiency
• Race-proven designs trusted by top powersports race teams
• CNC machined for optimal cam shape and profile for peak power output
• Built to exceed OEM piston strength and durability standards

Important Notes:

• This is an oversize piston (0.25mm over standard) – cylinder boring, sleeving, or replating is required before installation
• Piston kits are sold by bore size; standard and oversize designations are not indicated on the part number alone – verify your bore measurement before ordering
• Ring series: CD (Alloy Steel, Ferrox coated, chrome plated, internally notched)

Wiseco has been at the forefront of forged piston manufacturing since 1941, and the Pro-Lite series remains the go-to choice for riders seeking reliable performance from the track to the trail.
