Polini Zuma 50cc Full Circle Crankshaft with 10mm Wrist Pin.




Polini Yamaha Zuma 50 Full Circle Crankshaft. If you want more power out of your 2-Stroke engine, you need a full circle crankshaft. We now offer the Polini Full Circle crankshaft for the Yamaha Zuma 50/Minarelli 50cc 2-stroke. When you switch from the "Axe-Head" OEM crankshaft to the Full Circle Crankshaft, you gain an increase in gas shifting efficiency and primary compression. You are also able to rev the engine higher and gain more power along with a wider power band. This Polini crankshaft is also designed with the 10mm wrist pin, so you can use your stock piston instead of a specialized 12mm piston.
