This complete piston kit includes the piston, rings, wrist pin, and circlips for a comprehensive installation.

Key Features:

• Forged from high-silicon aluminum alloy for maximum strength and heat resistance
• 100.00mm bore size designed for precision fit
• 10.5:1 compression ratio optimizes horsepower and torque output
• Innovative forging design reduces weight while maintaining structural integrity
• Advanced piston skirt geometry minimizes friction and maximizes power transfer
• Complete kit includes piston, rings, wrist pin, and circlips
• Race-proven design trusted by professional riders and engine builders

Wiseco pistons are manufactured using state-of-the-art forging processes that create a denser, stronger grain structure compared to cast pistons. This results in superior durability under high-stress conditions and extended service life. The high-silicon aluminum alloy provides excellent thermal expansion characteristics and resistance to detonation. Note that oversize pistons require cylinder boring or sleeving for proper installation.
