SSP-G 1500 RPM CVT Torque Spring – GY6 125/150cc

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

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.
