Title: Tribsa , I need help identifying my Frame ??????
Post by: Amanda Tribeeza on 27 Jun, 2018, 17:58
Hi,
Can anyone help me here,  I have just bought this , i think Tribsa, Not sure but i have a bsa frame number on Log Book as B40GB447 , Suggests a B40 frame ??? See pic. Engine a Triumph 5ta.
Can anyone confirm this as a B$0 frame, The Neck i think has been strengthened, Down the bottom left had side mounting , i cannot see a frame number, as it has been welded over to take the Triumph Mountings.Also any info on what wheels these are too would be great.

Thanks

Amanda

The frame number relates to an ex-Army B40WD motorcycle which used a 350cc B40 engine but in a later welded duplex frame dating to about 1967. The frame certainly looks as though this is how it started off life!.

ps. If you look closely at the LHS top front of the frame you will probably see 4 small holes where the original MOD contract plate was riveted on.

In terms of the wheels, these would have been a WM1 x 20" front and WM3 x 18" rear.
