To suit later Ducati Scramblers with 35mm rubber-booted forks, and rubber-booted rear shocks, to my knowledge. Ducati's original part numbers for the badly-chromed steel versions of these parts are 0689-37-320 and -325.
These are made in beautifully polished stainless spring steel. Fit and finish guaranteed fantastic. The listing is for one matching set of four, as shown.
