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.

Ultimate Trail Bike

Serious off-road fun starts with the fuel-injected 292 cc liquid-cooled four-stroke Single, delivering crisp response, quick-revving power and strong low-end torque. The KLX300R is built tough with an engine designed to withstand the rigours of hard trail riding.

Hassle-Free Adventure

Together with fuel injection, electric start offers hassle-free starting at the push of a button regardless of altitude or air temperature, while contributing to clean emissions.

Bridge the Gap

The KLX300R 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.

Wide-Range Versatility

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.

Lightweight Platform

A lightweight perimeter frame offers optimised 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.

More Than Style

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.

Find Your Fit

Tailor the KLX300R to your size and preference with ERGO-FIT four-way adjustable handlebar positions.

Ride Any Trail

The KLX300R is built for serious play and is equipped with long-travel suspension to confidently handle the rigors of aggressive off-road riding.

Soak Up the Trail

A o43 mm inverted front fork aides 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.

Venture Beyond

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.

Confident Control

Full-size wheels and powerful disc brakes make the KLX300R ready for tough off-road terrain.

Bigger Wheels. Bigger Fun.

Large-diameter wheels, measuring 21” at the front and 18” at the rear, efficiently overcome trail obstacles, greatly contributing to trail-riding performance.

Sure Stopping Power

Strong disc brakes add even more confidence and control, with a twin-piston caliper gripping a semi-floating o270 mm petal disc in the front and a single piston caliper slowing a o240 mm petal disc in the rear.
