If it is warped and deformed, it will cause clutch slippage and 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 engines set up. These items significantly improve the throttle response of your scooter and also have a higher standard of manufacturing and durability than the originals. The POLINI 'Speed ​​Bell Evolution' also has a high manufacturing quality and includes cooling fins and vents, which together ensure lower operating temperatures and better 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: Don't forget to order new clutch retaining nuts and a suitable holding tool. A polyamide V-belt, clutch and Malossi variator complete the correctly set assembly.###250.035 (POLINI)
