      Yamaha TZM150.

      Nicasil bore, 4HF-00 or 4AP-00 - 147cc

      Looks very close to matching DT/TZR crankcases, but not quite.

      TZM has the same stroke/ crankshaft as the 125s, really strange engine by Yamaha for the East Asian market. Rated at 34hp, apparently. But more like 30.

      hmmm...Looks like a crap TZR. Or just like a TZR50.

      And then a TZM 50, which I just found today, Thought man, that's pretty cool.

      But, street legal road bike for whom? An 8year old? Lke TDR80's they are hilarious, proper bits of kit, just shrunk in the washing machine.

      Keep it real

            1988' Japanese market promotional material. Japanese aesthetic has a way of producing great graphic design. I'd like to say this is a fairly rare find even coming from Japan.

            That bash plate though!? I want.

            88-92' or so, the DT125R is advertised with a DT200R headlight and Alloy wheels for the JDM market.

            These have to be the best illustrations I've seen out of the promo so far.

            The DT200R always had a Yamaha Mikuni TM28ss, was always in the pipeline for the 125R.


            I can believe that the intended output for a DT125R is 22ps, which is about 21hp.

                          KTM in from the mid 80's were pretty werid and poor quality. Some of the best looking MX bikes of all time I think. And in 1985, KTM's were coming out with (White Power) WP nowadays,.. USD forks and front AND rear discs.

                          For the late 1980s KTM's were pretty tech, but not very good by most accounts.

                          Just a cool and very forward thinking piece of engineering from 1989, I thought I would share MXA's Write up, the only Magazine to get to test it, for the KTM 125MX AMP Prototype.

                          http://amp-research.com/wp-content/files/MXA_AMP_KTM_May2013.pdf

                          A really interesting time in Motocross development and the beginning of real refinement of the 2stroke for off-road racing.

                              @Darty Yes darty! That video is quality. The rotax 123 is inferior to the 122 engine.

                              Great video

He must know those roads very well and I bet he's caned em loadsa times for-sure? Sweet looking RS125 he's putting through its paces, it sure looks and sounds like a race bike???

                                Great vid @Darty - thanks for sharing dude!!! 👍
