BSA ROCKET 3 A75- 1970

It's the "twin sister" of the Trident T150; they were developed in parallel (BSA belongs the same group as Triumph since the beginning of the Fifties). To differentiate them, the BSA engine was 10 angled forward in a double cradle framework. The last Rocket 3 left the factory at the end of 1972.
