==History==
Just a few years after introducing the [[BMW R90/6|BMW R90/6]] and [[BMW R90S|BMW R90S]], [[BMW|BMW]] upped the capacity of its range-topping flat-twins to 980cc for the 1977 season in the form of the '/7' series. The latter comprised the R100/7 tourer, which used the 60bhp version of the new engine, while the cockpit-faired R100S sportster and the fully faired [[BMW R100RS|R100RS]] superbike came with 70bhp on tap. Within a couple of years the R100/7 'naked' had been re-titled [[BMW R100T|R100T]] and gained an extra five horsepower, while the others - together with the new [[BMW R100RT|R100RT]] super-tourer - continued to use the 70bhp engine.
