Primary gear shaft
We went as far as modifying the primary gear shaft to accommodate a pulley and clutch/bell assembly derived from the scooter world.
Having become the connecting element between the newly designed components, this shaft has been reinforced with an increase in the shaft Ø to 13.5 and is supplied with a nut, oil seal and roller shell for mounting.

Attention: in order to fit the primary gear shaft included in the kit, it is necessary to have fitted Malossi primary gears art. 6718630 or 67 7021.
