If you go back to the history of Ducati , you’ll know that the 60’s wasn’t exactly all too kind to the Italian bike maker. With the onus being dubiously put on producing two-stroke bikes, Ducati went back to bikes in the latter part of the decade, developing the "wide-case" single engine in ’67 and ushering a whole new range of bikes that included the Ducati 250 Mark 3.
Despite carrying the same basic overhead-camshaft engine architecture, the 1970 250 Mark 3 featured revised crankcases that were much wider at the rear where it mounted the frame. The sump capacity was increased to 2.5 litres, and the kick-start was much stronger, as was the new rear frame section. Add all that with a 249 cc SOHC single engine mated to a five-speed transmission and you had a bike that was clearly worth all the attention it received.
In addition to receiving a single filler fuel tank, the 1970 250 Mark 3 also received a speedometer and tachometer mounted on the top triple clamp instead of in the headlight shell. The example that was presented at the 2012 RM Auctions in Monaco is an older restoration model that is in very good condition, with good chrome and a very original specification.
This classic Ducati had an estimated selling price of about €3,000 - €4,000, which is about $3,800 - $5,200 based on current exchange rates. Actual selling price was $4,545.
