Description

Fine-tune your QMB139 scooter's CVT clutch engagement with SSP-G Performance Torque Springs. The torque spring controls when the rear clutch engages, directly affecting low-end pull, acceleration feel, and overall CVT response. Available in 1000, 1500, and 2000 RPM options to match your riding style and engine setup. All SSP-G parts are sourced from top manufacturers in Taiwan. SKU: 169-207.
