Triumph Big Bore

Long time build. 1958 Hardtail Triumph Big Bore. A 750 big bore with a 5 speed gear set in a pre-unit tranny.


Springer front end with six spoke invader 19" rim.
Rear wheel is a 16" five spoke invader.
Sissy bar I made myself to match the springer.
Six volt electrical system works fine so far.
Exhaust pipes, not sure with shorty mufflers. Head is a 69 with the fins shaved off by hand.

Paint is purple metal flake. Ruff ride, great throttle response.

Thanks for looking. xlx85.
