The UMA Racing Torque Spring 1000 RPM (02T00670) is a performance-oriented CVT (Continuously Variable Transmission) component designed for the Yamaha Aerox 155, NVX, and NMAX.

 

Commonly referred to as the "Red" spring due to its color-coded tension rating, the 1000 RPM version is the ideal choice for riders seeking quicker acceleration and improved mid-range pull without sacrificing the smoothness of a daily-driven scooter.

 

Key Performance Benefits

  • Reduced Belt Slippage: By providing higher tension than the stock spring, it keeps the CVT belt tighter against the pulleys, ensuring maximum power transmission from the engine to the rear wheel.

     

  • Quicker Throttle Response: It allows the transmission to "downshift" faster when you twist the throttle, providing an immediate burst of speed for overtaking in city traffic.

  • Superior Durability: Crafted from super-stiff, high-grade steel, it is engineered to resist "spring fatigue" (where springs lose tension over time due to heat and constant compression).

     

  • Optimized for 155cc Engines: While it provides a sportier feel, the 1000 RPM rating is balanced enough to maintain a decent top speed, making it more versatile for touring than the stiffer 1500 RPM (Purple) variant.

Why Upgrade to the 1000 RPM Red Spring?

The stock spring on the Aerox is designed for fuel economy and low-noise operation, which can sometimes lead to a "sluggish" feeling when accelerating from a standstill. The UMA Racing Red Spring solves this by holding the pulley in a lower gear ratio for slightly longer, allowing the engine to reach its powerband more effectively.

Recommended Pairings

For the most significant performance gains, this spring is best used as part of a Stage 1 CVT Upgrade:

  1. UMA Racing Pulley Kit: To optimize the shifting curve.

  2. Lighter Roller Weights: Usually 10g to 12g rollers are paired with the 1000 RPM spring for a balanced "Street-Sport" setup.

Installation Note

Installing a torque spring requires a clutch spring compressor tool or a specialized CVT wrench. Because the spring is under high tension, professional installation is highly recommended to avoid damage to the clutch nut threads or personal injury.
