The BSA Rocket Three / Triumph Trident

.




The BSA Rocket Three/Triumph Trident was the first true modern superbike and the last major motorcycle developed by the original (Triumph Engineering Co Ltd) Triumph company. It was badge-engineered to be sold under both the Triumph and BSA marques.
The Rocket3/Trident was the first-step development of Triumph Motorcycles' plan to move on from the basic vertical twin. The engine was to give the 750 cc power required by the US market while avoiding the vibration associated with an increase in capacity of the existing parallel-twin design.
