Mines long gone now, that thread dave linked has some pretty decent info in it though, I do still have copies of the parts breakdown for the Bebe's that the now gone DomiRacer sent me It was actually a poster size layout so they scanned sections of it for me, so its not that great but I can scan what I have and forward it to you if you need it.
Yours is the early version, All Domiracers parts got auctioned off from what I saw but I dont know who picked up the Moto Beta/premier stuff. It might be worth doing a little searching or calling British cycle supply to see if they have any idea of who may have bought those parts as they picked up alot of domi's stock. I dont recall if they had seats but I remember them having NOS tanks and some other cool stuff still when they were still in business.
Looks like your tires are alright but I just unearthed a few NOS 10" MT74 Pirelli's that were used on those bikes that will be for sale if they need replaced :thumbsup:
They are fun bike to ride, at least on the street. the clutch baskets like to stick when they sit though, and 3rd gear gets troublesome on a well used bike. The actual engine was used on quite a few bikes Broncco and even Bonanza briefly offered it, just the sidecovers were different for the most part.
