Can someone tell me what this thing that looks like a clutch drum attached to outside of the front sprocket is? What does it do? Looks like it is from your country Carlo.

Wow.....never seen that......its a belt drive Buell disguised to look like a Ducati.

Go out on a limb......belt drive starter motor??? Actually....I cant tell if that is a pulley?? or outboard countershaft support?

Hi, si parravano is a team from Frosinone, they are very imaginative mechanics, I must say that I have no idea what that contraption could be, I think I see an external guided bearing, I think there is a gearbox shaft protruding outside in anomalous way, and with the crankcase the shaft is guided externally by a bearing, at least I think.
