KLR650 fit you nicely at 35"
The new Versys 300 would be fun
Both are completely difference riding styles so "fun" is relative to what you're looking for. If I wanted to ride through turns and curves and was handed a KLR, I wouldn't be having fun....or at least not as much fun as the cbr or ninja.
Also, the Versys 300 is such a new model, very difficult to find used and won't find one around the 3k mark easily.
