One of the most significant developments in the production of Fabio Taglioni's Ducati singles was the introduction of the first 'wide case' model in 1967, with production proper commencing the following summer. Changes to the 'wide case' models were not merely confined to the rear engine mount, Taglioni and his team taking the opportunity afforded by the redesign to incorporate a stronger con-rod and big-end bearing, and increase the capacity of the lubrication system. There were also improvements to the gearbox. In '68 Ducati launched the first of its legendary 'Desmo' roadsters in 250cc and 350cc (actually 340cc) capacities, these two top-of-the-range super sports variants being distinguishable from the valve-spring models by their extra chrome and restrained 'D' decals on the side panels. Later that same year the Ducati roadster single appeared in its largest '450' (actually 436cc) incarnation, which offered considerably more torque courtesy of the substantial hike in capacity.

According to the accompanying DVLA Motorcycle Inspection Report (compiled by The Old Italian Bike Register), this 450 Desmo "has been fully restored to an excellent condition matching its original mechanical specification, it is 100% correct and has not been modified in any way". The machine was imported into the UK in 2019 and has had only one owner in this country. Additional documentation consists of a NOVA confirmation, a dating certificate, and a V5C.
