Stock original "untouched engine" 1981 KDX420 Enduro that you can go riding today. Very fast. This is a one year motorcycle that is constantly going up in value. It is unique because it can be added to your collection of motorcycles or it can be used as a "dirtbike". For its condition it would be rated GOOD, the rear stop light does not work but everything else pretty much functions on it including the front headlight.No leaks, No funny noises. Frame is straight. Rear tire is like new, front tire still good. Starts within 3 kicks this is a big motor with lots of compression.
