Eliminate belt slip and optimize your shifting curve with the Polini Performance Torque Spring Set. Specifically engineered for the GET Motor Honda Ruckus and Metropolitan, this kit replaces the weak factory contra spring to provide consistent pressure on the rear pulley. Whether you are running a stock setup or a highly modified 50cc engine, these springs help keep your CVT in the powerband longer, improving uphill climbing and snappier throttle response.
Every rider’s setup is unique, which is why Polini includes two distinct spring rates in this master set:
This spring set (243.020) is a direct-fit performance upgrade for the following models:
Mechanic's Note: If your Ruckus "bogs" when you hit a hill, your stock spring isn't pushing back hard enough.
Tuning Tip: Start with the 7% spring for a daily commuter. If you find the belt is still slipping or you want more aggressive "gear" holding, step up to the 15% blue spring.
Pro Tip: These work best when paired with a Polini Hi-Speed Variator for a total transmission transformation!
