If your clutch bell has a blue taint due to overheating, or its interior noticeably worn or damaged, the clutch shoes will not last as long as they could do. If it is warped and misshaped, it will cause clutch slip and a jerky acceleration. This means it requires immediate replacement.
POLINI produce the 'Speed Bell' clutch bell as an economically priced alternative to the original item or as part of a lightly tuned motors set up. These items noticeably improve the throttle response of your scooter and also have a higher standard of production and durability than the originals.
The POLINI 'Speed Bell Evolution' also has a high quality of production and includes cooling fins and openings, which together ensure lower operating temperatures and improved performance. A further development of this clutch system is the 'Speed Bell Evolution II'. The 'Evo II' clutch bell has even larger cooling fins and openings than its predecessor and is also 100 gr. lighter.
SIP-TIP: Do not forget to order new clutch fixing nuts and a suitable holding tool. A polyamide V-belt, Malossi clutch and variator complete the overall set up properly.
