Own an 85 200x and several 250r's. Personally, I love the R's, but their some what awkward when riding in the deep woods without decent trails. Open spaces, trails, sand and quarries. They like to 'grip it and rip it', not cruise along at slower speeds. The 2 stoke can be a little more maintenance at times, but is FAR EASIER to work on and greater availability of parts. Easier to build up and modify IMHO. ATC ADDICTED gave a good description.
