Im 99.9% sure that is a 1984 honda atc 250R, judging by the linkage on the rear swingarm. It would be a great deal for $200! The 83-84 250R's have much better suspension than the 81-82R. You can ramp a 2nd gen fooler high, no problem! The other parts laying there look like they belong to an 84 as well. One thing I can tell just by looking at it, is that there is a good chance the swingarm bolt is siezed, and will be a real 



to get out. Some patience, penetrating oil, heat, and a BIG sledge
and large punch bar outta do the trick. Pick them up! Always good to have extra parts when you are in a bind.
