This group is dedicated to classic Triumph motorcycles. But not all of them, only the pre-unit twins.
I have to precise what a PRE-UNIT TWIN is! We call a pre-unit, an architecture of motorbike which has the engine separate from the gear box. It is in opposition whith the unit construction which has the engine and the gear box in the same casing.
It can be a Bobber, Cafe racer, Chopper, Dirt Track, Dragster, Triton, Tribsa............. or of course an original model
If you have any of these TRIUMPH pre-unit Twins motorcycles photo's, go on, join the group and post them here.
