I recently purchased a Trackmaster frame + Ceriani MX fork with the intention of building it up as a street scrambler for my girlfriend.  She has several 1960's Honda twins but we don't have any two-wheel 2-strokes in the garage.

I believe the frame was configured to suit a DT1 engine, but my understanding is that other engines are compatible with the mounting points?

Looking through the model specs on this site, I think an RT2 or RT3 would be the most suitable engines for this application, but would appreciate any comments on pros/cons of other engines.

I'm interested in hearing from anyone who has owned or built a similar Trackmaster.  In particular, I'm curious as to whether the swingarm is configured to fit a stock rear DT1 wheel or something else so I can start accumulating parts for the build.

Hoping this link will provide access to a pic.

With respect, & especialy respect to your Lady, a 360 would be hard work after an electric start honda twin. DT1-2 or 3 would be ok and an easy ride plus easy to start. I'm sure you've heard the 360's take no prisoners when starting & can do damage they kick back so hard. Mind you, retard it well back & lower the comp plus the built in decomp in the front of the cylinder & that would soften it up good. I had a very worn out RT1 360 which is piston port & with the decomp operating it was good to start plus it had the retard mechanism built into the flywheel. Sorry, i'm not doubting your ladies ability but just thinking out loud, so maybe i'll get back in the corner. Really love to see pics when you can load some through a thingy like 'imgur'. Best of luck with the build.
I see my writing style change near the end if it shows your end which happens sometimes & i've no idea why--don't think i hit anything but mabe i do.

Her Honda CL77 is kickstart only, but fair point that a 250cc DT would be easier to start than a 351cc RT.

Between the DT1, DT2, and DT3 I'm guessing the DT3 would be preferred?  Would appreciate hearing pros/cons.
 

Hope your project is moving ahead. Just noticed your picture link and after seeing it, I was reminded of another thread on the forum.
