2010 KAWASAKI KLX 250 KL250, Brand New!! Don't miss out!! When the pavement ends, the fun doesn t have to stop if you re riding the Kawasaki KLX 250S. Lights, turn signals and all the other things you need to ride on the street are here, but the KLX250S s heart belongs in the dirt. With its 249cc liquid-cooled single, long-travel suspension and rugged steel frame, this lightweight machine lets you access the best of both worlds. That compact and powerful four-stroke single-cylinder engine fires right up through the miracle of electric starting, and it mounts nice and low beneath a lightweight, high-tensile steel perimeter frame to provide a low center of gravity and enhanced maneuvering on tight trails. A gear-driven engine balancer keeps it nice and smooth for greater comfort and less fatigue on longer rides. The 34mm semi-flat slide Keihin CVK carburetor provides great throttle response and broad, smooth power not to mention fantastic fuel economy.
