SF1 (1972)
Several mechanical changes were introduced on this model, including a new cylinder head and crankshaft, and the replacement of the 30mm VHB Dell'Orto with larger 36mm PHF instruments with accelerator pumps. The exhaust balance pipe was not only vastly increased in size but its location was also transferred, to underneath the engine. Conti replaced Lafranconi as the silencer supplier, which also meant an entirely new shape. Lucas switchgear replaced the earlier Italian-made assemblies, while a mechanical piston (incorporated within the casting) was fitted between the two cams on the brake to ensure improved operation.
