XL vaguely amusing trailster that can be thrashed through the corners, though its minor off-road abilities come in handy when you run out of road. The top end suffers first, either through neglect or thrashing but the bike is easy to work on. Later (1987 on) XR600 is lighter (275lbs against 375lbs), more powerful; more capable. Engine developed into one of the toughest big singles around.
