Introducing the 2024 Kawasaki KX112…

The KX112 is Supermini class ready with its class-maximum 112cc engine tuned to deliver strong torque for strong drive out of the gate and corners and model-specific shrouds designed to accommodate the typically taller racers in this class. Like all Kawasaki KX motocross machines, the KX112 is ready to propel its rider to the top of the podium.

The 2024 KX112 offers race-winning potential in a highly competitive class, boasting a strong low-end torque that riders can take advantage of to feel faster everywhere on the track.

The two-stroke, single-cylinder KX112 features a bore and stroke of 52.5 x 51.6 mm. The engine paired with the powervalve system delivers strong low-end torque that translates to holeshot performance out of the starting gate and a stronger drive when exiting corners. Intake and exhaust port timing contribute to the KX112's strong low rpm torque, while its piston profile delivers durability and contact surface for the piston ring helps the initial bedding-in performance. The carburetor settings have been fine-tuned to match the powerful engine and contribute to sharp response across the rev range. Complementing the powerful 112cc engine is a 6-speed transmission that has been designed to withstand the engine output.

A sturdy high-tensile steel perimeter frame was designed to harness the engine's power, offering advantages of strength and torsional rigidity that allows riders to push hard on the track. The chassis is matched with 36mm inverted front forks that offer excellent damping and bottoming resistance. Riders can fine-tune their settings through 20-way adjustable compression damping. On the rear, Uni-Trak rear suspension offers preload, 24-way compression and 21-way rebound damping adjustability in order to allow each rider to tailor their settings based on size and skill level.

The KX112's large 19-inch front and 16-inch rear wheels nicely bridge the gap between minibikes and full-sized race bikes, accommodating larger youth riders and helping to navigate over the bumps and ruts commonly found on motocross tracks. The wheels are fitted with Dunlop MX33 tires that offer excellent grip and control. The bodywork of the KX112 follows along the lines of its bigger KX counterparts by forming a slim ergonomics package that facilitates rider movements and contributes to strong factory looks.

FIT TO WINYoung riders will experience added confidence with improved ergonomics, a narrow frame profile, and an adjustable ride position designed to accommodate a wide range of rider heights.

STAY GROUNDEDDunlop MX33 tires offer excellent grip, slide control, bump absorption and durability. Large 19-inch front and 16-inch rear wheels contribute to a taller overall seat height and higher ground clearance (compared to KX85) that's well suited for supermini riders.

TAKE FIRSTSupermini wheels, MX33 Dunlop tires, and disc brakes give the KX112 enhanced grip and stopping power. Riders can fine tune settings with an adjustable suspension and rely on a sturdy perimeter frame to help them push hard during long motos.

RADIATOR SHROUDSBoasting both functionality and bold looks, the new radiator shroud design facilitates rider control and movement while embracing an aggressive factory-inspired style.

AGGRESSIVE KX LOOKSFactory-inspired styling shows off the race-winning potential while allowing aspiring racers to look just like their Kawasaki heroes as they race to follow in their footsteps.

The Kawasaki KX motocross and off-road motorcycle range returns stronger than ever for 2024 with its championship-winning packages.Leading the way is the KX250 motorcycle with a powerful 249cc engine, electric start, KYB suspension, and a coned disc-spring hydraulic clutch that have led to a championship heritage that boasts 18 AMA professional titles and 196 race wins since 2004.

Joining the KX250 is its KX250X cross-country motorcycle that has been purposely tuned for off-road competition. Developed to dominate off-road racecourses in both the woods and the desert, the cross-country KX lineup offers riders the required components for off-road competition straight from Kawasaki along with the dominant engine and chassis performance found on the KX250.

Kawasaki's mini motocross lineup consisting of the KX112, KX85, and KX65 motorcycles returns for 2024 and is ingrained with a long list of achievements that have stemmed from building champions from the start. The KX112 supermini racer bridges the gap to full-size motocross bikes and boasts a powerful 112cc displacement engine, the largest in its class. It's joined by the KX85, which shares much of the same technology found on the KX112. The KX65 returns as the most compact bike in the Kawasaki KX lineup and the starting point for aspiring champions.

The Kawasaki Team Green racing team has been the dominant force in amateur racing for nearly four decades, providing contingency and an unmatched level of trackside support to racers across the nation. Under the Team Green racing program, a trackside support system consisting of local, regional, and amateur motocross and off-road events across the country has been put in place. There, Kawasaki technicians and race transporters can be found providing critical parts and technical assistance to all riders. Kawasaki's efforts, matched with the input from aspiring young stars, have produced winning products across its lineup.
