saboteur
Turbocharged
On my Standard it locks with the key and has a second pull tab for back. Needs a mounting plate that screws in where the standard pillion pad attaches.
Canberra, what's the model number on yours? Triumph could not help me a bit, as the numbers have changed and they have no record of former parts numbers. I have the same set up as you, with backrest, and no go.
