1970 Ducati Mark 3 Wide Case – Pristine example with Borrani rims and Dell'Orto carburettor

Designed by the legendary Fabio Taglioni, Ducati's first overhead-camshaft single appeared in 1955. Desmodromic valve operation was a feature of the racing versions and would later be applied to the sportier roadsters. The first major revision to the original design occurred in 1967 when the 'wide case' engine was introduced, which featured an aft engine mount wider than before and numerous other improvements, the most significant being a stronger big-end assembly.

The first of the revised 'wide case' models to appear was the 350 Mark 3 that debuted at the Cologne Show in September 1967, with production proper commencing the following summer. Changes to the 'wide case' models were not merely confined to the rear engine mount; Ducati took the opportunity 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. Mid-way through 1968, the Mark III was introduced in both valve-spring and Desmo versions, differences between the two being confined almost entirely to the cylinder head.

From 1969 the Mark 3s had a single filler fuel tank, and the 1970 model received a speedometer and tachometer mounted on the top triple clamp instead of in the headlight shell. The Mark 3s were beautifully balanced machines.
