It is fun, nice and light, nimble, makes the right noises.  I built it for my Brother, I'll deliver it this week.  The old DT bikes of the '70s make a pretty good platform for this type of conversion because Yamaha (and others) didn't yet know how to build a purpose built dirt bike.  I did brace the frame just a bit to help with the added traction of the Avons on pavement.  Geometry is right on for what it is.  I have an RT 360 motor that is a bolt in for this chassis and I'll build that motor over the winter for next season, 250 is good for now.  I have three others that I'm working on same basic idea. 
  Cheers, 50gary

Here's an R/DT360 we built a few years ago for a 6hr endurance race at a local kart track.  Looks to be pretty similar spec.
