One of the great chapters in the history of the rotary engine was written in the development of the Norton Rotary motorcycle. Barely kept alive in development for years, it finally reached production, went racing and won spectacularly against all comers - the first racer itself being built in the back of a small house by a few people in their spare time in six weeks!
The culmination of the Norton Rotary was to have been a rebirth of Norton itself as a power in the industry. Alas, the ...uhhh... management had other ideas. Eighteen tons of crushing debt later and the marque went Devo in the early 90's, though not before producing a small number of extremely beautiful motorcycles.
