Borrowed this from BritBike.Com
"The T65 was/is an oif Triumph 650 Trophy with BSA tank badges and 'BSA' cast into the alternator timing cover. Of those that were built (somewhere between 200 and 300, the exact number varies depending on source), certainly the vast majority (if not all) went to the South Australia Police, a long-time BSA user that had an outstanding order when BSA went tits-up in 1972. Some sources mention supply of a small number to one of the United Arab Emirates (Abu Dhabi or Doha iirc) and possibly some to South Africa.
It's possible that the T65 was intended for public sale; every now-and-then, odd prototypes of various BSA models badged with other British makers' logos surface in one or other of the British old-bike mags. Certainly also, even now, it's relatively easy to find official T65 parts books and owner's manuals on Fleabay for not a lot of money, and it's on Kim's BSA CD. In the end, BSA's failure became such a train-crash that the management of the newly-formed NVT decided, probably wisely, to give the BSA name just a quiet funeral.
Finally, another peculiarity of the T65 - although they're oif Triumphs, with oif forks, they have the pre-oif drum front brake."
