Description Polini G3 Performance Clutch for Yamaha Aerox / Jog 50cc. Performance clutches come with stiffer springs than your original clutch, meaning that more rpm is required for them to engage. This results in better acceleration and take off, because your engine is at a higher rpm, and producing more power at the point that the clutch engages, or ‘kicks in’.
