Hi All. Finally getting around to finishing my Trophy 1200 cafe racer and trying Thruxton seat from 1200 rs. What I`m looking for is the rear subframe from Thruxton frame. The part the seat fits to and the supporting rails. Cut off at main frame top and bottom. So subframe is complete.I know it is welded and not bolted on Anyone know a breakers that might have damaged frame ? This is seat I have.
