Wiseco 40008M06800 Honda CR Forged Piston Kit - CBR600RR 13.5 1 68mm

The Wiseco 40008M06800 is a high-performance forged piston kit designed for the 2007–2011 Honda CBR600RR, featuring a 13.5:1 compression ratio and a 68mm bore diameter. Built for riders who demand maximum power and reliability, this piston delivers measurable performance gains over the OEM unit.

Wiseco pistons are forged from high-silicon aluminum alloy, a material that offers superior strength, reduced weight, and exceptional thermal resistance compared to cast alternatives. The high-silicon content also improves wear resistance along the cylinder wall for extended service life.

Key Features:

• Forged high-silicon aluminum alloy construction for maximum strength and durability
• 13.5:1 compression ratio for increased horsepower and throttle response
• 68mm bore diameter — oversize pistons require professional cylinder boring or sleeving
• Optimized piston skirt geometry minimizes friction and maximizes power transfer
• Precision-machined crown profile engineered for the CBR600RR combustion chamber
• Kit includes: piston, rings, wrist pin, and circlips
• Direct fitment for 2007–2011 Honda CBR600RR

Whether you're building a track-day weapon or a high-compression street engine, the Wiseco 40008M06800 piston kit provides the performance and reliability that professional engine builders trust. Note: Oversize pistons require cylinder boring or sleeving to the specified bore diameter prior to installation.
