Obscure KTM part needed. :-(

I have a trail bike, a Sukuki DR750 Desert Express. The previous owner
did some home mods to it, and put a KTM front and rear end on it...
It's been a great fun bike, but due to a "offroad mishap", I managed to
break the rear disk brakes caliper slider. I don't know exactly what
bike the KTM parts are off, but I have a good(ish) lead that it is
likely to a KTM '89 enduro (250cc ish). As it's a old KTM, I cannot get
bits from KTM direct, and have tried Jim Aim, who also could not help.
I'm now clutching at straws...

Anyone know of a online bike used spares search? Or a bike breaker that
may be able to help (S/SW/SE ideally).

If anyone thinks they may be able to help, I chucked some photos of the
bike, and the brokem caliper slide online here:

You would be best advised to take the remains to an engineering 'shop' or
anywhere there is access to a good milling machine or better still, a CNC
machinig centre. A good college may be able to help or get onto the local
model engineers club.
A competent machinist will easily get a block of ali machnied up as a
replacement part, looking at the 'remains' of the old one it's not too
complicated. It may cost you about £75-100 though I'd reckon. You could even
'fabricate one if you had a TIG welder and good drill press. The other
alternatave would be to replace the whole front-end with another make,
preferably Jap, with more easily availabe spares. A whole front-end off a
late '80s motocrosser XR/CR/KX would probably be fine.

It's actually the rear caliper that's busted. I have the original DR750
back wheel, and drum. I may stick that back on. The previous owner did
mention however, that the DR750 with the drum at the back was shit,
compared to the KTM 250 disc.... Still if it gets it moving again...

 

Doh! Rear? Should have looked at photos more carefully! The easy way to
solve this would be to use another caliper from a bike with similar/larger
disk width (working area not thickness) and knock up a simple caliper
mounting palte from 10mm ali plate. Then again, you could indeed just stick
the old DR rear one back in as you said. I didn't realise you actually
still had the original wheel.
