Wiseco 2394M08100 Pro-Lite Forged Piston Kit Bore - 2-Stroke 81.00mm

The Wiseco 2394M08100 Pro-Lite Piston Kit is a high-performance forged 2-stroke piston kit featuring an 81.00mm bore, engineered for powersports engines that demand strength, reliability, and responsive power delivery. Built on decades of 2-stroke piston expertise, the Pro-Lite series delivers a proven balance of performance and durability for all-purpose 2-stroke riding.

Wiseco forges all of its pistons in-house in the U.S.A., controlling every stage of the manufacturing process from raw material to finished skirt coating. This ensures consistent quality and tight tolerances that cast OEM pistons simply cannot match.

Key Features:

• Forged aerospace-grade aluminum alloy construction provides a superior strength-to-weight ratio over cast alternatives
• Extra lightweight piston design delivers instant throttle response
• CNC-machined for optimal cam shape and profile for peak power output and extended service life
• Computer-engineered piston skirt profile minimizes cylinder wall friction
• Anti-detonation grooves and ring land diameter eliminate ring blow-by while maximizing performance
• Horizontal slot-pin oiling reduces friction and provides scuff resistance, along with a pressure seal groove for maximum ring seal
• Race-proven design trusted by top race teams across Supercross, Motocross, and GNCC competition

Kit Includes:

• Forged Pro-Lite piston (81.00mm bore)
• High-performance piston rings
• Alloy wrist pin
• Circlips

This kit provides everything needed for a complete top-end rebuild. Measure your cylinder bore before ordering to confirm correct clearance. Note: Oversize pistons require cylinder re-sleeving or boring to the appropriate specification.
