Think your safe, there.......spoken with him, and he's not done anything for Montesa........yet.

Thanks brewtus.....interesting

I'd be loath to bin it...............its a little piece of history, and once its been crushed etc, its gone forever........

Thanks for your thoughts section swept On the 123 cota it when new it came running 20" front and 17" rear , which seems to be near impossible to find, certainly in the uk................(same as 172 cota swing arm, which would allow and give room for 18" tyre/rim. Wheel, at present is right back in s/arm, as per your idea, but tyre (at present am running 400x18) still rubs on chain guard, and very close to swing arm pivot. My other thought is going down to a3.50 x18 section tyre, (only found one distributor of these in uk) which will give slightly more clearance Have also posted question in Montesa forum

Anyone know if the motor of early 123/172 cota (red one) will fit into later 200 frame ? Am running a 123 with 400x18 rear tyre, and clearance in swing area isn't good to all.........easiest way would be to find a 172 swing arm, but they seem like hens teeth in the uk I'm aware exhaust/silencer is different on the 200 cota

Can anyone give me an idea if an early cota 123 engine will fit into a later cota 200 frame........( and all 123 ancillaries swap over), although I realise exhaust/silencer is different) Reason for asking is at present running 123 with 400x18 rear tyre, which is rubbing, (still using 123 swing arm, as not been able to find a 172 arm)..and the '200', I believe was the later version of the 172 with the wider swing arm. Any idea's ?

Thanks for link

Thanks cota172, I did a uk based internet search, and nothing came up, which I based my earlier answer on; Hmm, unless keeping to standard spec, still prefer to stay 21" front and 18" rear, myself.

Thanks iconic558, thankfully the 247 seems to be ok, at the mo...........just as well really as the 123/172 is in the process of being fettled, - and under engine protection being added (clutch arm is under engine, and quite exposed)

How have you attached it to frame, have you left original mesh in place ?

Yes, as far as I know the original size tyres are no longer available, so only option, really; Even finding 3.50x18 trials tyres isn't easy, certainly non of the major tyre makers list them, and whilst I know the 172 cota shared its frame with the 123 cota, the swinging arm must be different, as 172 ran 400x18 tyre, which wouldn't have rubbed, like it does on my 123.

I'm running 21" front wheel and an 18" rear (have a 400x18 in there at the mo, but it rubs, so going down to a 3.50x18)

Look forward to seeing them, Mikr my 123 cota, work in progress.

Aye but there were 11 of them, and all they had to do was kick a ball about.....................and get well paid for doing so. Your lad, well done to him, by the way.......achieved summat any of those highly paid posers couldn't even dream of doing.

One big + for me, although not found I need it, is they also do a 'waterproof insert'..........which, on a multi day WET trial might be a bonus. (as I say, my feet have remained dry all the times I've worn mine, and that has involved scrabbling about in stream beds, when I've dropped montesa.....)

I wear Forma Boulders, and find them comfy for all day use, also wear them for when greenlining.......again, no issues.

Roll on retirement................and the move away from the crowded south, to Penrith. (and a good smattering of clubs running trials in the area)

Having brought a rider back to life after he suffered a (suspected) heart attack, whilst on an isolated Byway, a few years ago, whilst I can appreciate, and laugh at the above scenario, its just amazing just how much you remember - when faced with summat like that, yes, quite a while previously to that incident,.. I had attended a basic first aid course....in the days when it was 'breath of life and chest compressions'. (And in the days before mobile phones were as available as they are now) Think the Op was right to raise this subject............and I think its generated a healthy (pardon the pun) conversation.

Hi Rabie, the tubless issue would not be a problem, as I run tubes;

Thanks motovita, might have to go down that route here in the uk.

Cheers, mate.

I don't think OP was suggesting going the Ambulance route, etc, just that if there war any first aid trained riders/ observers in attendance, they be identifiable; By the very nature of accidents, any Fiist Aid, administered 'on site' is just that.........First Aid; Regarding liability........it would be a pretty poor day if the person trying to help someone in trouble (of whatever kind) stood back and worried about any repercussions.......(and here I'm speaking as a First Aid trained person) Another point here,.........whilst yes in an ideal world, 999 is last resort, in some area's of the country, any sort of phone reception is hit and miss. Can understand your reasoning, On It, for your post, as well.............tis an interesting topic, maybe's as Trials 'like some other sports', is moving forward, and sections are by the very nature of the machinery being ridden, now, are getting more technical, the OP's raised question does have some relevance.

Whilst on the subject of decent Trials tyres, I'm looking for a 3.50x18 (no idea what that converts to in new sizing).............Have found one on ebay, not a known make a far as I know, and I guess at a push it will do the job, - but ? Cannot go 400x18 as it rubs on swing arm Bike is a 70's 123 cota, which originally had 17" rear wheel............ Anyone any idea's ?

All good and valid points

Reading with interest this thread, after spectating at Highland Classic this year,.........looking to enter next, and coming from a county not noted for rocky going (southern England), am looking to fit external bashplate to my 123 cota......extended to cover underslung clutch arm.,..also moving footrests back n down slightly, so thanks for pic's Wobbler.
