Polini Clutch Spring Set for Honda Dio and Vespa 50cc Models
This clutch spring tuning kit is built for Honda Dio and Vespa 50cc scooters and gives you a way to fine-tune how your ride gets going. Engagement RPM can be adjusted so the setup suits your modifications better. It is one of the GY6 50cc scooter parts that can help your scooter respond well to changes such as a modified exhaust or a sport setup. Because it helps power transfer to the rear wheel more effectively, it can noticeably improve acceleration.
Performance Tuning
The set contains twelve color-coded springs, each with a different tension level. They cover engagement RPMs from 4,000 to 7,000. Choosing the right spring lets you improve holeshot and overall pickup, with the clutch delivering more torque as the engine revs climb.
Construction Details
Each spring is made from high-tensile alloy, which holds its tension when exposed to heat cycling and friction. That helps keep performance steady over the long term. The kit is matched to original factory clutches, so anyone comfortable with basic scooter maintenance should find it straightforward to fit.
