If you don't need new, look at a TTR250 Yamaha. 30# lighter than a tw200. I sold one last fall, good bike. I have a crf230f honda now. 30#+ lighter than a tw200. Lower seat than the TTR250. A few mods, jetting, exhaust, forks and rear shock. Great for a late 60 year old on single track (me).
I can dog the shi it out of my buddies (in my age group), in single track, on their 450's.
Easy to plate in Idaho, although I run around town with an restricted plate and no lights. I had another crf230f that I plated w/light,etc. I also plated the above TTR250, w/lights, etc.
