A lot of those bikes lose a piston or valve about that time. Don't be so tempted. If it had 15,000 miles on it I'd be jumping at it too, but the miles are kinda high on this one. It's a sport bike, not a cruiser. 18,000 rpm engines don't last as long between rebuilds as engines that spin half as fast. If the engine's been gone over I might go for it, but otherwise I'd keep looking. The bike does look pretty good, but the miles give me pause. Best of luck to you.
