Dr. Pulley GY6 50cc 107mm Clutch BellDr. Pulley GY6 50cc 107mm Clutch Bell is designed specifically for the GY6 50cc. However, we've figured out it works on a Ruckus too! This does require a special spacer that spaces the clutch and bell apart enough just to clear properly. Otherwise, it will hit, making this not a complete plug and play. This does fit the GY6 50cc spot though! Application: Clutch Bell 107mm GY6 50cc Piaggio Peugeot Honda Ruckus with Jog Clutch and Rear Pulley
