The KLX300R is the ultimate high-performance trail bike for off-road thrills, bridging the world between a weekend play bike and a full race bike. As the leader of the KLX lineup, the KLX300R combines the best of both engine and chassis performance to create the ultimate lightweight, fun off-road machine.
Serious off-road fun starts with the fuel-injected 292cc liquid-cooled four-stroke engine, delivering crisp response, quick-revving power and strong low-end torque. The KLX300R trail bike is built tough with an engine designed to withstand the rigors of hard trail riding.
Together with fuel injection, electric start offers hassle-free starting at the push of a button regardless of altitude or air temperature. Clean-burning efficiency earns the KLX300R trail bike a California Green Sticker for year-round trail access.
The KLX300R trail bike combines the fun of weekend play with the exhilaration of racing. The strong engine and highly capable chassis satisfy both trail riders looking for a machine ideally suited for recreational riding with friends and family, and racers looking for high performance.
Smooth-shifting six-speed transmission offers a gear for every situation. Short final gearing (50/14) complements the engine’s low- to mid-range focus, enabling riders to maintain momentum when navigating technical off-road trails.
A lightweight perimeter frame offers optimized rigidity for stability at speed while the short wheelbase facilitates agile handling. High ground clearance allows riders to more easily clear technical terrain features, resulting in confident trail riding.
The slim design of the frame and bodywork helps the rider grip the bike for increased control, while the KX™-inspired seat design offers great freedom of movement for off-road riding.
Tailor the KLX300R trail bike to your size and preference with ERGO-FIT four-way adjustable handlebar positions.
The KLX300R trail bike is built for serious play and is equipped with long travel suspension to confidently handle the rigors of aggressive off-road riding.
A 43mm inverted front fork aids in stability and control even on rough terrain. The fork settings take advantage of the long travel, using a lower spring rate to allow damping to work over a wider stroke range.
The rear Uni-Trak single-shock system features preload adjustability along with adjustable compression and rebound damping to suit a wide variety of terrain, riders and preferences.
Full-size wheels and powerful disc brakes make the KLX300R trail bike ready for tough off-road terrain.
Large-diameter wheels, measuring 21-inches at the front and 18-inches at the rear, efficiently overcome trail obstacles, greatly contributing to trail-riding performance.
Strong disc brakes add even more confidence and control, with a twin-piston caliper gripping a semi-floating 270mm petal disc in the front and a single-piston caliper with a 240mm petal disc in the rear.
