The KLX300R comes equipped with full-size off-road wheels and tires, using a 21" front and 18" rear, and long-travel suspension for optimal ground clearance.

The KLX300R is the ultimate high-performance off-road trail bike, bridging the gap between a weekend play bike and a full race-ready KX competition machine. As the leader of the KLX lineup, the KLX300R combines the best of both engine and chassis performance to create the ultimate trail bike for off-road thrills. It is a lightweight, fun off-road machine that helps ensure that there is an affordable, capable, and durable motorcycle in the KLX line-up for every rider in the family to get out and attack the trail.

GET OUT AND PLAY

The Kawasaki KLX off-road lineup brings enjoyment to novice and experienced riders alike and is largely popular for its easy-to-ride character, incredible capabilities while on trails and low maintenance needs. For 2024, Kawasaki welcomes the return of its KLX300R, KLX230R, KLX140R, KLX140R L, KLX140R F, KLX110R, and KLX110R L models that are built to suit a wide variety of riders, and new for 2024 is an exciting new color option of Battle Gray in addition to the traditional Lime Green.

The KLX300R motorcycle is the ultimate high-performance trail bike for off-road thrills, bridging the world between a weekend play bike and a full race bike.

POWERFUL ENGINEULTIMATE TRAIL BIKESerious 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.

NIMBLE CHASSISMORE THAN STYLEThe 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.

LIGHTWEIGHT PLATFORMA 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.

SOAK UP THE TRAILA 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.

RIDE ANY TRAILThe 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.

BIGGER WHEELS. BIGGER FUN.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.

CONFIDENT CONTROLFull-size wheels and powerful disc brakes make the KLX300R trail bike ready for tough off-road terrain.

ENGINECompact Liquid-Cooled Engine• Flat top piston with pentroof combustion chamber delivers power-enhancing 11.1:1 compression ratio.• Lightweight piston, piston pin and connecting rod allow power-producing revs without excessive vibration.• Piston skirt designed to minimize contact with the cylinder wall and wide connecting rod big-end bearings enhance durability.• Dual high-capacity radiators similar to those used on Kawasaki KX motocross machines provide excellent cooling efficiency. The slim radiators feature the same tightly-packed cores and fin design of the KX250

4-Valve DOHC Cylinder Head(KP)• Provides maximum valve area for optimum flow.• Boosts low-end torque.• 38.5° included valve angle for a compact head with straighter, more efficient ports.• Cam profiles and intake port design contribute to the smooth, quick-revving engine character.• A cam lobe for each valve with shim-under tappets has less reciprocating weight for efficiency at high rpm.

Nikasil-Plated Cylinder(KP)• The incredibly hard coating in the aluminum cylinder bore means superior heat transfer with less weight.• The coating holds lubrication well, resists abrasion and seizure, and allows tight piston-to-cylinder clearances for more horsepower.

Kawasaki DFI(KP) System• 34mm throttle body delivers precise engine response for better throttle control in tight trail situations.• Provides stable fuel delivery regardless of changes in air temperature or altitude.• Contributes to easy starting, whether the engine is hot or cold, and cleaner emissions

Electric Starter• Combined with DFI, starter button provides easy engine starting.• Electric starter and the Kawasaki Automatic Compression Release (KACR)(KP), which automatically lifts an exhaust valve at cranking rpm, makes starting the KLX300R easy.

Gear Driven Engine Balancer(KP)• Engine runs smoothly from idle to redline.• More rider comfort and less fatigue on long rides

Digital Capacitor Discharge Ignition (CDI)(KP)• Digital ECU precisely controls timing, no matter how fast the RPM changes.• Easy starts and reliability under extreme conditions.

U.S. Forest Service-Approved Spark Arrester• U.S. Forest Service-approved spark arrester allows access to designated public riding areas.

Six-Speed Transmission)• Six speeds provide a gear for varying situations.• Short final gearing complements the engine's low-mid range focus, making navigating tight trails easier.• Smooth shifting for ease of use.

TRANSMISSIONHigh Tensile Steel Perimeter Frame(KP)• The frame is built up of box-section and tubular high-tensile steel.• The 26.9° steering head angle and 56.5 inch wheelbase contribute to quick trail maneuverability.• Optimized frame rigidity contributes to excellent straight line ability.

FRAME43mm Inverted Cartridge Fork(KP)• Fork settings utilize a softer spring rate to allow damping to work over a wider stroke range for better front-end feeling.• 20-way compression damping adjustment.• Cartridge maintains more consistent damping force by minimizing aeration of the fork oil.

Uni-Trak Rear Suspension(KP)• The nitrogen-filled, aluminum body, remote reservoir rear shock has 20-way compression and 18-way rebound damping adjustment and stepless threaded spring pre-load.• Lightweight, extruded aluminum swingarm contributes to overall frame rigidity balance. D-shaped spars are attractive and KX-type chain adjusters facilitate maintenance.

Front and Rear Disc Brakes• Twin piston front caliper grasps a 270mm front disc, the same size as that found on the KX250/450, for incredible stopping power.• Single piston rear caliper and a 240mm disc to give strong, reliable performance.

SUSPENSION• Also from the KX line, the upper triple clamp provides two mounting positions for the reversible handlebar clamps so that the handlebar can be set in one of four positions with a 35mm range of adjustment.• Adjustable front brake lever position suits various hand sizes and preferences.

Rider Interface• Inspired by the KX line, the KLX300's seat-tank junction was designed to give the rider maximum freedom of movement and helps the rider to slide farther forward in turns. Flush seams between the shrouds, seat and side covers also provide freedom of movement and aids moving around on thebike.• The seat has a slip-resistant top for grip and smooth sides for rider mobility.
