The KLX®300SM ultimate lightweight supermoto motorcycle takes the fun to the streets in full supermoto style. A quick-accelerating engine, paired with light, agile handling, evokes the playfulness within. Suspension, wheels, and brakes are optimized for supermoto, and the overall aggressive styling means business. The KLX®300SM is quick to steal the scene with equal parts performance and attitude powered by a 292cc, fuel-injected, liquid-cooled engine. Experience a rewarding spread of power across the rev range. Smooth power delivery and crisp throttle response helps riders of all skill levels maneuver through stop-and-go city traffic, navigate country back roads, or experience the exhilaration of supermoto racing at their local track. Electric start offers easy starting and fuel injection helps with reliable starting in a wide range of conditions and contributes to clean emissions and good fuel economy. The KLX®300SM motorcycle is built with a slim, lightweight perimeter frame that’s maneuverable but rigid at higher speeds to help with straight-line stability. With the smaller front wheel, the caster angle (25°) and short wheelbase contribute to quick handling. Suspension performance offers 9.1 inches of travel up front and 8.1 inches in the rear, ideal for supermoto riding. The 43mm inverted cartridge-style front fork has adjustable compression damping to optimize fork performance for conditions and personal preference. The Uni-Trak® rear suspension offers bump absorption and rebound damping adjustability, and fully adjustable preload, allowing riders to tailor shock settings to personal preference. Substantial braking power comes thanks to a large 300mm semi-floating petal disc and twin-piston caliper up front and a 240mm petal rear disc and single-piston caliper. Agile supermoto performance is further enabled with 17-inch wheels and road tires contributing to better handling on the street.
