Armstrong CMT250 Trials bike

Post by Bonnielad » Wed Aug 24, 2016 9:19 pm

My 1982 Armstrong CMT250 trials bike needs to make room for my next project.First designed by Sammy Miller. His name is emboldened on the crankcase.
Frame number 80 of approx 100 made.
An honest description – both the good and the bad to give a clear picture for you:

Frame, swinging arm, fork shrouds, yokes & various brackets all stripped & powder coated.
Rebuilt engine with new seals & bearings.
New Mikuni carburettor.
New mudguards, cables, grips & levers.
Brakes relined. Rear wheel re-spoked. New back tyre.
New chain & sprockets.
Zinc plated brake & gear levers.
Exhaust header powder coated with a special heat resistant coating.
………………………………………….
Side stand is made up based on original photos.
Exhaust is original, not pretty, poorly welded and not fully sealing on the joint.
One of the four front spindle clamps has stripped its thread and I haven’t got round to re-tapping it.
Fuel tank & seat assembly has been stripped, strengthened and repainted. The extra fibre glass now makes it a very stiff fit. It fits and works fine but is starting to show cracks again at stress points.
The new decals are crinkling slightly, probably due to poor adhesion over the bulge and the effects of petrol spills.
The replacement neoprene seat cover is too soft and has a nick in it. I’ll probable re-cover this.
Fuel tank has developed a leak, Sureseal is on its way.
……………………………………………
Apart from all that, the bike fire up easily, and it goes and stops as it should.

My God! Until everything was written down I didn’t realise how much time and effort had gone into this.
The Armstrong Trials specialist reckons its worth about £1500 so I thought I'll put it on here first at £1450 ono.

Did anyone else see the Armstrong article in last week's MCN? They didn't get all their facts right (American indeed - as if!) but they did say that the trials bikes were the cream of the crop in the early eighties so I won't argue with that bit.
