We have stacks of various aluminum & steel rear sprockets that fit bevel drive Ducati twins (520 & original spec 530) as well as PASO (520) which have the same bolt pattern etc as bevels.
Please choose the sprocket type you prefer from the choices to the right (# of teeth, chain size, color, material).
The 520 sprockets that were originally for PASO also fit bevel twins if you want to get a 520 front sprocket and chain which we also stock, just as strong but lighter than a 530 setup.... They are steel and are priced the same as the 530 sprockets that are steel.
