I've been offered a early 80's Montesa 123. It's got full size wheels i.e. 18 & 21. I haven't seen the bike as it is some distance away. Is it a pretty much full sized bike or is it a smaller youth frame ? I don't know much about Monts to be honest. Help would be appreciated as it would save me a wasted journey.

where is it and how much

It is "full sized" in the terms you quote but smaller than a 250 so lighter. I recall that Brian Hutchinson always had good results in the SSDT on the small Mont. I don't know how far you will have to go but I know of a 200 Mont (same bike, bigger barrel) for sale in Scarborough (not me selling by the way).

Thanks for the responses. It's a lovely looking bike and still has the road going gear. I don't think it's seen much trials. Paid £1200 for it and it needs nothing. I may put some trick shocks on it though. I would be interested to hear of any good mods that can be done to the bike. I've bought it as I had a serious injury riding in feb and Ive decided not to compete anymore. But I would like to marshall a bit and I will use it to ride round the sections whilst doing that. Nice to give something back.

Apparently the best mod is to your kickstart technique, not to the bike, as the mechanisms are notoriously weak and some care in use is advisable.
