Description
When a 2-stroke piston fails or shows signs of wear, your bike’s performance and reliability suffer immediately. The Wiseco Piston Kit 595M05500 replaces worn components with forged aluminum construction and precision engineering, restoring combustion efficiency and throttle response. This complete kit includes rings, wrist pin, and circlips—everything you need for a straightforward rebuild without sourcing individual components.
Wiseco’s forged aluminum design balances strength with minimal weight, critical for 2-stroke engines where piston speed and durability directly impact power delivery. The precisely machined 55.00 mm bore optimizes combustion chamber geometry, translating to sharper acceleration and improved fuel efficiency across the RPM range.
