Has anyone got a clue what this is. Eng and frame number say it is a 10/75 DT125, 578-000158.
Certainly doesn't look like a DT. It has xt/tt500 shocks at the rear and a Honda front end. Foot pegs are welded to the frame and all welding looks "factory" quality, especially shock mounts. Any ideas?
-
the upper shock mounts and swingarm don't look original to me but I'll leave it to the darkside experts ;) maybe the frame was cut and the whole rear upright/subframe and mounts rewelded in a section. Any other welds to be seen that may indicate a cut'n'shut? Looks very much like my old DT/MX175 I had many moons ago!
-
It looks like a DT with a fairly ordinary LTR conversion done, although the rear frame loop looks far better than most hack-jobs.
The rare MX125C is similar to this bike, but the upper shock mounts are lower/further foward, and they run the YZ125C style motor (no auto-lube, painted black, bigger fins etc). The MX-C also has alloy rims, and non-cross-over exhaust, plastic airbox, etc.
The plastic side cover is probably YZ125C.
Other clues would relate to seat mounts (hinged or bolt-on), steering lock, exhaust mount near carby, and blinker mounts.
A pic of the rear brake pedal and footpeg would also help.

Hmmm... upon further inspection, it looks like it might have a MX/YZ-A barrel.
Is there a port for the oil injection?
What's the spacing of the intake boot/reed block bolts?
What's the prefix cast into the barrel (either on the side of the intake, or just above the base gasket).
-
Thanks for the interest. Part of the mystery is solved , it has a 175cc barrel ,prefix 45500, on it. Oil injection port ,yes. Reedblock bolt centre's are 55mm and 48mm approx. Engine appears to have been black earlier on.
-
One more shot of the shock mount.
-
interesting machine welds look good dont think factory some factory welds are terrible i wonder how the bike would go some one has spent a bit of time and money to do that thanks Michael. :)
-
i'm going to go out on a limb here and say the frame is the real deal MX125c,
the airbox is a good clue as it looks to fit well and be of an MX type design,
swing~arm and shocks look MX125c,
the wheels look to be DT with the steel rims,
Barrel is MX175 a/b if it's 455 prefix,
Head looks to be DT {low compression},
Pipe is definately DT, yukky poo......,
578 prefix shows DT125,
565 prefix is MX125c,
but, a 570 prefix should be an MX175c. which i've never heard of.
but should you be interested in selling this beast and live near Brisbane, i'd be interested. ;D
cheers.
-
Now that we've got the extra pics, I reckon I agree with Vandy - the frame, shocks, brake pedal and foot-pegs are MX125C.
Although virtually everything else seems to be DT or MX-A, rather than MX-C.
Shame that its been so butchered, but I want it too (and I don't care whether you live near Brisbane or not...;D ).
-
a few more shots.
Motor turns over with plenty of compression and feels smooth, will take head off for an inspection.
Would possibly be interested in selling /trading , need cash or parts to finish off a B50MX/Triumph.
-
try again
-
The other bitza I need a few bits for .
-
i wouldnt call the triumph a bitsa looks fairly complete thanks Michael. :)
-
frosty look closer for race tape holding on front guards ;)
-
pps .. i have 175 leading forks in the YZ to swap for them under forks if your interested. call goes out to anyone actually
-
hey nothing wrong with that race tape i use a bit of that mainly on duct work though can work as a quick seat repair too :)
-
race/duct tape works well when you are sitting back contemplating what to do.
Thanks to Mick and Nathan and all for the info on the DT/MX hybrid.
-
Hey its an interesting bike good luck with it thanks Michael. :)
-
I just got offered a 74/75 Dt 125 original as a pin if any one is looking, still has road rego and all the gear, blue tank, try to get a photo next time i see the guy.
