Description

SSP-G performance CVT torque spring for GY6 125cc and 150cc 4-stroke scooters. Rated at 1500 RPM engagement, this yellow progressive-wind spring delays clutch engagement to a higher RPM compared to stock — resulting in a more aggressive launch feel, improved mid-range pull, and higher sustained RPM through the power band. Direct drop-in replacement for the rear pulley torque spring on GY6 157QMJ / 152QMI-based engines. Made in Taiwan by SSP-G.

Key Features:

  • 1500 RPM engagement rating — delays clutch lock-up for a more aggressive, higher-RPM launch vs. stock
  • Progressive-wind conical design — smooth engagement ramp with increasing resistance through the power band
  • Yellow powder coat finish — easy identification and color-coding in multi-spring tuning setups
  • Direct drop-in fit for GY6 157QMJ / 152QMI rear CVT pulley torque spring position
  • Made in Taiwan by SSP-G

Specifications:

  • Brand: SSP-G
  • SKU: 169-97 | MPN: GY6 1500 RPM (Yellow)
  • Engagement RPM: 1500
  • Color: Yellow
  • Total length: 154mm
  • Inner diameter: 49.5mm
  • Design: Progressive-wind conical
  • Application: CVT rear pulley torque spring
  • Made in Taiwan

Compatibility: Fits GY6 157QMJ and 152QMI 125cc–150cc scooters using a standard CVT rear pulley torque spring. Universal fit for any QMJ / QMI / QMK engine platform with matching spring seat dimensions.

Tuning note: Higher RPM springs (like 1500 RPM) raise engagement speed for a more aggressive launch but may reduce low-speed crawl ability. Pair with appropriate roller weights to optimize your CVT shift curve for the desired riding style.

Off-road use only. Not intended for use on public roads or land.
