Ducati NON-folding rear sets for 250/350/450 wide and narrow case singles without kick starters. These English made rear sets thread into the 7/16" X 20" frame lugs on OHC singles and install with no welding, cutting, or frame modifications. Of course you will have to do some fiddling but this is the most complete kit we have ever seen. NOTE: Rear brake cable may need to be modified or re-routed to work with these rear sets.
