Fits:
A longer stroke means a wider powerband, more torque, and stronger top-end power. Ideal for performance builds looking to push the limits – for example, when paired with a 65mm bore (e.g. Malossi), this setup delivers an impressive 189.14cc.
Highlights:
Modified 55mm crank with 2mm offset pin
Increased stroke: 57mm
Rebalanced weights for smoother operation
Stronger torque and extended powerband
Built for durability and precision
Perfect for high-performance 2-stroke setups
Note:
This is a custom-built stroker crank. Crankcase machining (clearancing) is required to fit the longer stroke. Professional installation and setup are strongly recommended for optimal performance and reliability.
