1971 BSA 650 A65 Thunderbolt
Frame no. CE02373A65
Engine no. CE05029 A65T
Introduced in 1962, the A65 twin was the unit-construction follow-on to BSA's venerable A10 series. Marking it as a bold new step forward, the engine was treated to streamlined, so-called "power egg" styling, especially evident in the alloy side cases. Soon the company catalog would carry no fewer 11 different models powered by the new engine, in both 500 and 650cc displacements.
The last major upgrade to the A65 occurred in 1971, sadly just a couple of years before the factory was forced to close its doors. As shown by the Lattin collection's example, overall styling was clean and modern, led by a sporty fork assembly that straddled a new front brake featuring a huge, jutting air scoop. Also making a statement was the frame, painted a light Dove Gray.
The bike has an interesting history. Owned by a member of the Westinghouse family, it was left new in its shipping crate until 1980-81 when it was entrusted to Pokes Cycle in Seattle for final assembly and to be sold. Two owners later the all-original machine became part of Lattin's collection.
