BSA Rocket 3 (A75) Parts & Spares
BSA‘s 740cc triple shares its heart with the Triumph Trident but is very much its own motorcycle: inclined cylinders, a different frame and a set of cycle parts that do not cross over. That distinction is where most Rocket 3 parts hunts go wrong.
Obsolete Bike Parts carries over 100 line items for the A75, with the triple-specific components that are hardest to find held in depth.
Rocket 3 or Trident?
The A75 was built from 1968 to 1972 with its cylinders inclined forward, while the contemporary Triumph T150 stood its barrels upright. Engine internals largely correspond; frames, oil tanks, exhaust systems and much of the ancillary hardware do not. Our listings say which model a part suits, and there is more under BSA triples.
