As the 1970s wound down for Ducati, designer Fabio Taglioni found himself back in favour and produced a rabbit out of the hat. It was the 500-cc belt-drive camshaft V-twin Desmo Pantah, whose racing sibling, the TT2, would hand Ducati four Formula 2 world championships between 1981-84. Taglioni’s design was significantly smaller and quieter than the outgoing bevel-drive twins, as well as much cheaper to build. When the engine was boosted to 600 cc in 1980, the few teething troubles were solved, and the 600SL gained a better fairing and a hydraulic clutch. Electronics were by Nippon Denso, brakes were by Brembo, and top speed was increased slightly from the 500SL, at around 124 mph.
