1978 Ducati 900SS

Ducati’s second-generation v-twin engine – the 900cc ‘square case’ (actual capacity 864cc) – debuted in the 860GT of 1974 and the following year was used to power the new 900SS superbike. The latter was styled like the original 750SS that had been developed from Paul Smart’s 1972 Imola winner. More than just a simple over-bore, the ‘square case’ engine incorporated a new camshaft drive arrangement, improved oil pump, cartridge-type oil filter and electronic ignition. In addition, the gearchange was moved to the left-hand side and the frame altered to provide chain adjustment at the swinging arm pivot. As had been the case with the original 750SS, desmodromic valve gear distinguished the new sports roadster from its tourer counterpart. ‘Like the tamer valve spring version of the engine in the 900GTS it is uncannily smooth, while possessing a much more dramatically punchy power output than the soft touring motor,’ reported Bike magazine in October 1977. Breathing through gaping 40mm Dell’Orto carburetors, the 900SS engine produced 70bhp at 7,500rpm, an output good enough for a top speed of 135mph. The 900SS’s competition heritage was obvious on the road: ‘While other flash Italian bikes are basically roadsters dressed up and pretending to be racers, this is the real thing,’ declared Bike.

The motorcycle offered

The 1978 Ducati 900SS on offer here was the subject of a sympathetic mechanical restoration, including a general service of all mechanical parts, including engine with electronic ignition and brakes. With an original steel tank and black and gold livery, the bike presents well in good rider condition. The sale of the bike comes with a second one-piece tank/seat bodywork unit and fairing. Having been gone through to ready it for sale, the bike rides well with lovely V-Twin power that only a Ducati can deliver. However, having sat on static display, it may need further fettling.
