BGM 57mm Stroker Crankshaft

674.95

Unlock serious power with this BGM 57mm Stroker Crankshaft, professionally converted from a standard 55mm stroke. This crankshaft has been completely disassembled and rebuilt with a precision 2mm offset crank pin, extending the stroke to 57mm for increased displacement and performance.

These stroker crankshafts are built on demand and require approximately 4 weeks for production and assembly.

Product description

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.
