History/Production: Bimota was a bespoke motorcycle manufacturer created using the initials of the 3 founding partners: Valerio Bianchi, Giuseppe Morri and the brilliant frame and suspension designer, Massimo Tamburini.  Bimota’s reason for being was to optimize technically advanced engines, initially from Japanese manufacturers and mount them in an equally advanced custom Bimota frames, far superior to the flex prone and underwhelming frames produced by Japanese manufacturers at that time.

Unlike its Japanese powered Bimota predecessors, the DB1, was the first Bimota to use a Ducati engine and thus an all Italian bike for the first time. It was also the world’s first bike with an integral fairing including the tank. It was praised for its compact size, packaging and superior handling. The only criticism was a lack of power and this was addressed with the second series DB1 S model with bigger carburetors (from 36 to 40 mm) and a less restricted exhaust resulting in 10 extra HP (now 72 hp). The final version, this bike, a DB1 SR, performance was further improved by incorporating Ducati Montjuich camshafts, 41 mm carburetors and a 2 into1 single aluminum exhaust adding another 10HP (now 80 hp). New 3 spoke magnesium wheels were also an added feature.
Production: DB1 SR 153 units (DB1 453 units, DB1 S 63 units)
