The Kyosho VSW030-01 soft clutch spring helps tame aggressive throttle and gives GS15R-powered rigs a gentler engagement point. It is a practical choice for riders wanting cleaner initial acceleration.
This spring was developed with GS15R engines in mind, improving the transition window so the clutch engages more smoothly and reduces jolts during acceleration from standstill.
Installing the VSW030-01 is straightforward for those who service clutches. Its lower tension means the clutch will engage sooner, which can shorten reaction time off the line and aid controlled starts.
