Product Details
DESCRIPTION: Compression springs do a couple of things. First they supply the pressure to engage the belt. They also determine the rate at which the CVT transmission changes from low to high gear. A 1000rpm spring will go into a higher gear sooner than a 2000rpm spring. This NCY 1000 rpm compression spring is specifically for the Yamaha 125’s.Fits the following:Vino 125Zuma 125 / BW’s 125

NCY 1000 RPM contra spring (also called a compression or secondary spring) for Yamaha 125cc 4-stroke scooters. Dark-coated high-fatigue silicon-steel construction resists tension loss over time, keeping your CVT settings consistent even after thousands of miles. The 1000 RPM rating delays upshifting slightly longer than stock, keeping the engine in its power band for better hill climbing and mid-range response. Provides faster back-shifting when you get back on the throttle in stop-and-go traffic. Made in Taiwan by NCY. Sliding weights not included.
Key Features:
- 1000 RPM rating — delays upshift slightly for better mid-range punch and hill climbing
- High-fatigue silicon-steel construction resists tension loss (“spring sack”) over time
- Dark-coated finish for heat and corrosion resistance in the rear pulley environment
- Faster back-shifting (downshift response) for improved stop-and-go rideability
