This is a great thread, how good am I for starting it?
Marc and Mark, you two read my mind. I was going through my small stash of VMX mag last night looking for this sort of stuff, and found the two Tribsa's in issue no.8. I was going to ask tonight why the Triumph thing hadn't been touted all that much and open the thread to find you two had beaten me to it.
Tonight's really stupid question is, the "unit" reference ie. pre unit or unit. what does that mean? I'm serious, I don't know
Some other questions, after going through my book of 30's 40's 50's British bikes I noticed some had what I would think of as non-conventional shift pedal and rear brake. ie they're on the opposite side to what I'm used to. Are there specific engines or manufacturers (other than Bultaco) where this is the norm?
Firko, you mentioned the early RM tank as an option, do all the major components of the bike have to be pre65 or just the running gear, frame and suspension?
