Wiseco has become world renowned for their work, building race winning pistons for compact engines featuring small bores, multi-valves, and high RPM applications for many years. Wiseco utilizes experience learned from a diverse back ground of the most sophisticated engines in such venues as Formula 1, Indy Racing League (IRL), NHRA Pro Stock Bike, AMA Superbike, and AMA Motocross to design and manufacture the highest technology Sport Compact piston available.
Bore: 81.00mm / 3.189"
Oversize: Standard
Stroke: 3.437
Rod length: 6.200
Gasket Thickness: .040
Compression Ratio: 8.94
- Aerospace grade materials, forged for maximum strength.
- Precision tolerance CNC machining for quality, repeatability and performance.
- Crown thickness and ring lands designed for power adders such as forced induction (turbos & blowers) and nitrous oxide. Note: High compression pistons are generally designed for naturally aspired application.
- High Quality Piston Rings featuring positive twist nitride steel top ring, Napier 2nd ring, and nitrided rails on a specially designed expander for the best oil control.
- Wrist Pins constructed of chrome moly steel material for the ultimate in strength.
- Honed/Reamed pin bore holes for a precise tolerance fit between wrist pin and piston.
- Wire Retainer Clip Lock, featuring chrome silicon material for the ultimate yield strength.
- Piston deburred for performance and reliability.
- All specs based on U.S. engine codes unless noted.
- Included: Pistons, Rings, Wrist Pin Locks, and Wrist Pins.
*Item ships straight from the USA, 2-2.5 weeks arrival from date of order
