UMA RACING CONTRA SPRING (UNIVERSAL)

Performance Benefits:

• Maximizes power transmission: By applying more consistent pressure, it helps ensure the belt remains engaged properly under load. 

• Reduces belt slippage: Because of its stiffness and design, the torque spring helps prevent the CVT belt from slipping during launch or high torque demand.

• Quick response in acceleration: Helps improve throttle response / how quickly the clutch “grabs” under acceleration. 

Durability: Built for performance, so it’s more robust than stock contra springs. 

Brand / Quality: From UMA Racing, a well-known name in performance scooter parts, so this is a performance-grade spring, not just a cosmetic / minor upgrade.

Install Consideration: Because it's a stiffer spring, when you use this, you might need to adjust other parts of the CVT setup (rollers, variator, belt) to get optimal performance and avoid excessive wear.
