Yamaha Zuma 105mm winged clutch bell
This is a remake of a clutch bell design that has already been on the market for quite some time (e.g. Malossi, Adige and Metrakit). The additional cooling fins on the outside of the clutch bell result in increased mass, but also in a temperature that is up to 70°C lower.
These clutch bells only fit engines with 105mm inner clutch bell diameter. Before ordering, please check whether your clutch has two shoes (diameter = 105mm) or three shoes (diameter = 107mm).
