Description

Wake up your GY6 scooter's takeoff with a coordinated CVT upgrade. The SSP-G 1500 RPM performance kit brings the clutch, torque spring, five-blade bell, variator and adjustable drive sheave together, giving 125cc and 150cc four-stroke GY6 riders a more responsive setup without piecing together the major pulley components separately. The 1500 RPM clutch setup is aimed at stronger low-speed engagement, while the variator and drive sheave give you a matched foundation for transmission tuning.

Key Features

  • More responsive launch: 1500 RPM clutch springs and torque (contra) spring support a performance-oriented takeoff.
  • Coordinated CVT package: Clutch, bell, variator and adjustable drive sheave are supplied together.
  • Tuning-ready variator: Includes 20 × 12mm, 12g roller weights and a 148g cast-aluminum drive face with a translucent blue anodized finish.
  • Distinctive rear-drive setup: Black five-blade clutch bell pairs with the yellow clutch assembly and torque spring.
