2003 Kawasaki KLX 400SR, Exceptional local one owner KLX with low miles. - Whether it's out on the trail, cruising through city streets or on backcountry roads, the street-legal KLX400SR can do it all and does it with performance and style. Based on the Kawasaki KLX400R motorcycle, which is designed for Enduro and offroad use, the KLX400SR can go places its muddy sibling can't. But don't let the license plate fool you. Underneath all the headlights, taillights and turn signals is a double overhead cam, four-valve, liquid-cooled dry-sump four-stroke engine that delivers aggressive power on demand.
