2024 Kawasaki KLX300SM Totalmotorcycle.com Features and Benefits


Compact Liquid-Cooled Engine
• 292cc displacement is17% more than typical 250cc class models for more power while maintaining the light weight and nimble feel of a 250.
• Flat top piston with pentroof combustion chamber delivers 11.1:1 compression ratio.
• Lightweight piston, piston pin and connecting rod allow power-producing revs without excessive vibration.
• A gear-driven engine balancer ensures smooth power delivery throughout the powerband, delivering greater rider comfort on long rides.
• High-capacity Denso radiators similar to the KX line provide high cooling efficiency. Their slim profile and tightly packed cores make the radiators smaller and lighter, while the special fin design provides excellent heat dispersion.
• Radiator fan cover located behind the radiator directs hot air down and away from the rider, significantly increasing comfort when negotiating heavy traffic. Redirecting the air also helps keep the tank and other parts that contact the rider cooler, further increasing rider comfort.
• Catalyzer and secondary air system help reduce exhaust emissions so that the KLX300SM meets strict emissions regulations and can be sold in all 50 states.

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

4-Valve DOHC Cylinder Head(KP)
• Camshaft profiles from the KLX300R contribute to top-end performance and quick throttle response.
• 4-valve cylinder head provides maximum valve area for optimum flow.
• Boosts low-end torque.
• Cam profiles complement intake port design and 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.

Kawasaki DFI(KP) System
• 34 mm throttle body is equipped with a sub-throttle that contributes to mid-high rpm performance.
• Ultra-fine atomizing 10-hole injector helps boost performance and provide very smooth throttle response.
• DFI provides easy starting, smooth idling, increased performance and better fuel mileage.

Electric Starter
• Electric starter and the Kawasaki Automatic Compression Release (KACR)(KP), which automatically lifts an exhaust valve at cranking rpm, makes starting the KLX300SM easy.

Digital Capacitor Discharge Ignition (CDI)(KP)
• Optimized ignition timing contributes to a strong yet easy to use power delivery at low and mid-range rpm that transitions smoothly to the powerful top-end.
• Digital ECU precisely controls timing, no matter how fast the RPM changes.
• Easy starts and reliability under extreme conditions.

High Tensile Steel Perimeter Frame(KP)
• The frame is built up of box-section and tubular high-tensile steel.
• The steering head angle and short wheelbase contribute to quick handling.
• The incredible frame rigidity contributes to excellent straight line ability.
• Rear frame rigidity has been optimized to accommodate an accessory rear carrier.


43mm Inverted Cartridge Fork(KP)
• 16-way compression damping adjustment.
• Cartridge maintains more consistent damping force by minimizing aeration of the fork oil.

Uni-Trak Rear Suspension(KP)
• Lightweight, highly-rigid aluminum D-section swingarm helps reduce unsprung weight.
• Rear suspension linkage and damping settings provide a firm ride and a more planted feel in corners.
• The nitrogen-filled, aluminum body, remote reservoir rear shock has 16-way compression and rebound damping adjustment and threaded spring pre-load.

Front and Rear Disc Brakes
• Petal brake discs help reduce weight and the wave pattern helps to clean the brake pads for better brake performance.
• Twin piston front caliper grasps a big 300mm disc for incredible stopping power.
• Single piston rear caliper and a 240mm disc to give strong, reliable performance.

Wheels and Tires
• KLX300SM has 17-inch wheels fitted with street tires.


Relaxed Ergonomics
• The ergonomics put the rider in a relaxed, upright position, for easy maneuverability and control.
• The KLX300SM has a slightly narrower handlebar than that of the KLX300, which contributes to its unique styling.
• Footpegs are positioned close to the bike’s centerline for a slim riding position suitable to both on- and off-road riding.
• Thickly padded seat contributes to comfort on longer rides.
• Seat height and design were carefully considered to help riders reach the ground for added confidence when stopped.
• Narrow fuel tank contributes to the comfortable riding position and has a lockable, hinged one-touch cap.
• The KLX300SM features stylized mirror shapes that contribute to a more aggressive look.

Digital Instrumentation
• All-digital instrument panel features bar-graph tachometer, digital speedometer, clock dual trip meters and warning lamps.



The KLX300SM is powered by a supermoto-inspired 292cc liquid-cooled DOHC engine with a rewarding spread of power across the rev range. The engine features cam profiles sourced from the KLX300R off-road model, an electrofusion cylinder and ultra-hard coating in the aluminum cylinder. The result is a crisp throttle response that complements the motorcycle’s rider-friendly low to mid-range and offers improved engine reliability. A lightweight piston, piston pin and connecting rod also contribute to power-producing revs.

The engine has low reciprocating weight thanks to the use of a cam lobe for each valve, with shim- under tappet arrangement, which also contributes to better efficiency during high RPM. With a bore and stroke of 78.0 x 61.2 mm, the engine boasts 292cc. Rider comfort on longer trips is also increased in part to the engine’s low mounting point, which effectively lowers its center of gravity. A flat piston and pent-roof combustion chamber deliver a 11.1:1 compression ratio.

The fuel injection system contributes to reliable starting in a wide range of conditions and electric start makes firing up the KLX300SM a breeze. Optimized ignition timing and a gear-driven engine balancer also contribute to a smooth engine with an easy to use power delivery, providing maximum rider comfort during longer trips.

Several updates to the radiator deliver superior cooling efficiency, including the use of dual radiators and slimmer radiator sizing. An innovative radiator fan cover directs hot air down and away from the rider, significantly increasing comfort when stuck in heavy traffic or riding in warm conditions.

Gear ratios on the KLX300SM facilitate shifting for optimal performance on and off the race track. The KLX300SM features a honeycomb catalyzer and a secondary air system for cleaner emissions, along with a spark arrester.



Front and rear petal disc brakes on the KLX300SM offer impressive stopping performance with a twin-piston caliper gripping a 300 mm semi-floating disc up front and a single-piston caliper gripping the 240 mm disc in the rear.

The KLX300SM comes fitted with 17-inch front and rear wheels mounted on IRC street tires, for plenty of spirited riding possibilities. Excellent wheel rigidity contributes to light, smooth handling and offers outstanding durability.



The KLX300SM features a box-and-tubular-section high-tensile steel perimeter frame that creates a slim, lightweight package, offering maneuverability and  precision at the track or on the street. A 26.7-degree caster angle and short wheelbase provide quick handling characteristics, while the highly rigid frame ensures a composed ride. The lightweight, aluminum D-section swingarm also contributes to low unsprung weight.

The 43 mm inverted cartridge-style fork handles the suspension up front and comes with compression damping adjustability. A Uni-Trak suspension can be found on the rear, which contributes to  road holding ability and bump absorption. A gas-charged shock with preload and rebound damping adjustments allows riders to tailor suspension settings to better suit different riding conditions. In total, the KLX300SM has 9.1-inches of total wheel travel in the front and 8.1-inches of travel in the rear.



If riders are looking to tackle the city streets in style, they need to look no further than the 2024 KLX300SM. Aggressive KX-styled styling can be found from the front to the rear fender on the KLX300SM, including a compact LED headlight that is the centerpiece of the sporty front-end that is short front-to-back, giving the area a sleek overall look. The stylish front fender follows a similar pattern to the KLX300, but it’s exclusive, sharp and light design was tailored for on-road riding.




Riders can personalize their KLX300 and KLX300SM as they see fit with numerous Kawasaki Genuine Accessories to choose from, including a hand guard set, tapered handlebar, handlebar pad, and rear carrier.
