The EVO clutch bell for Piaggio Maxi Scooters with 125-180cc 2-stroke engines. Very lightweight and easy-spinning and CNC-machined from one solid block, unlike the Malossi Wing Bell with its cooling ring. This has the advantage that the bell runs 100% true and no weighting is required. The weight is also dramatically reduced, making it probably the lightest “Wing Bell” on the market. The compact design means the diameter could be maintained, although this item is a fraction larger than the original, but suitable for building with tight clearances. The large ventilation openings reduce the temperature of the bell and give it a more aggressive look. All-in-all a great quality, high-end bell.
