1971 BSA Rocket 3


BIG CHANGES FOR THE 1971 BSA ROCKET 3
1971 was a watershed year for BSA and Triumph. The Big Twins (BSA A65 and Triumph Bonneville/TR6got all new frames, suspension, brakes, cycle gear and bodywork, a complete redesign with the exception of the engines, which carried over. The Triples got the same treatment, and benefitted from much the same hardware, with the exception of the frames, which also carried over.
1971 BSA ROCKET 3 FRAME COLORS
Early 1971-model BSA A65sand Rocket 3s came with dove gray frames (above). Not silver, mind you. Dove gray. Some people loved the look (me included), most hated it. It also showed off all those oil leaks. By the end of the 1971 model year, BSA had gone back to a more conventional black frame (below).
