Upgrading the stiffness of your torque spring will have a huge impact on the performance of your scooter. The torque spring affects your acceleration and low end torque. Increasing the stiffness will give you smoother acceleration and greater power off the line. The performance gains are well worth the investment.

Ruima offers torque springs with 10%, 15%, and 20% increased stiffness over your stock spring, allowing you to tune your transmission to fit your needs.
