A diamond-like coating on the finger followers helps protect against wear. Large-diameter, lightweight titanium valves and a high-performance piston with a dry film lubricant coating contribute to strong performance at all RPM.
A high-capacity coned disc-spring clutch offers a more direct feel and maintains a consistent feeling even as the clutch heats up under heavy use. The air-box construction features a tapered intake funnel for high rpm performance and dual injectors deliver a smooth, instant response, and contribute to engine output at high RPM.
The KX250’s slim aluminum perimeter frame is based on its KX450 counterpart and with lightweight, nimble handling and slim ergonomics in mind. The lightweight construction is composed of forged, extruded, and cast parts and offers optimal rigidity balance.
The addition of a KX450 swingarm delivers the rigidity necessary to match the frame and helps to increase traction at the rear wheel. The center of gravity and key dimensions such as swingarm pivot, output sprocket and rear axle locations have all been carefully selected so that the rear tire drives the bike forward.
Large-diameter 48mm KYB coil-spring front forks offer optimum action at the initial part of the fork stroke and feature large-diameter inner tubes, enabling the use of 25mm damping pistons and deliver smooth action and firm damping. A Kashima Coat on the fork’s outer tubes creates a hard, low-friction surface to help prevent wear abrasion on the inside of the tubes.
On the rear, a KYB shock unit complements the front fork and features dual compression adjustability, which allows high-speed and low-speed damping to be tuned separately. Kashima Coat on the tank cylinder helps prevent wear abrasion and reduces friction. A new Uni-Trak rear suspension system mounts the linkage arm below the swingarm, allowing a longer suspension stroke and uses the same linkage ratios as that found on the KX450 motorcycle.
Adding to the numerous factory-style racing components on the KX250 are petal disc brakes, which include an oversized 270mm Braking brand rotor that delivers strong braking force and superb control. A 240mm Braking brand disc can be found on the rear and contributes to controllability and optimized stopping performance.
Just like its KX450 counterpart, the KX250 continues with its class-leading Ergo-Fit comfort thanks to its adjustable handlebar mounting system and footpegs to fit a variety of riders and riding styles.
Sleek bodywork with factory-style in-mold graphics help ensure it’s the sharpest looking bike in the paddock and further reflect its highly-tuned performance. The bodywork has been designed to facilitate rider movement, while the fuel tank design allows for a flat progression from the seat to the tank, which gives the rider greater freedom.

In addition, all-new for 2022 is the KX112 supermini racer that 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 several new features with its bigger KX112 counterpart, plus the KX65 returns as the most compact bike in the Kawasaki KX line-up.
Building on the strengths of its predecessor, the KX112 offers more race-winning potential in a highly-competitive class. The increased power makes the KX112 feel faster everywhere on the track, especially where riders can take advantage of its stronger low-end torque.
The increased displacement on the 2022 two-stroke, single cylinder KX112 comes by way of a 5.8mm longer stroke and now features a bore and stroke of 52.5×51.6mm. The new 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.
Power and torque are improved across the rev range with peak power significantly greater. Updated intake and exhaust port timing help contribute to the KX112’s stronger low rpm torque, while a revised piston profile improves durability a redesigned contact surface for the piston ring improves the initial bedding-in performance.
In order to reduce the lateral force placed on the piston, and generate more efficient power, the connecting rod was increased by 7mm. A 4mm greater crankshaft web offers increased strength to match the greater offset of the crank pin with the new longer stroke engine. The carburetor settings have been fine-tuned to match the all-new engine for a sharp response.
Complementing the more powerful 112cc engine is an all-new six-speed transmission and stronger bearing retainers for the small-end needle bearings and big-end needle bearings with greater load capacity to help harness the increased engine output. Larger gear dogs improve durability and thrust washers have been added for to improve durability and reduce friction.
A sturdy high-tensile steel perimeter frame was designed in order 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, enabling the all-new KX112 to be ridden hard while maintaining comfort.
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.
Similar to the larger KX models, petal disc front and rear brakes can be found and are used to achieve strong braking performance. A large-diameter 220mm front brake is gripped by a dual-piston caliper, while the 184mm rear disc is held by a single-piston caliper.
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 new Dunlop MX33 tires that offer enhancedgrip and control. .
Kawasaki continues its unmatched commitment towards providing riders with unmatched comfort with class-leading Ergo-Fit adjustable components like an adjustable handlebar mounting system that allows riders to tailor fit their riding style and size by selecting from among six possible handlebar positions. Collars offer a choice of three heights, while reversible handlebar clamps allow two forward/rearward positions.
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. The top of the fuel tank design is flat in order to facilitate sitting farther forward to weigh the front wheel when cornering and a slim, flat seat design makes it easier for riders to adjust their riding position.
A new shroud design accommodates a wider range of young riders and makes it easier for taller riders to find a good fit on the bike. The minimalist side covers were made as small as possible and the seams between the shrouds, seat, and side covers are flush in order to allow the rider to move around on the bike with ease.
The new aggressive looks, paired with the ergonomic fit that facilitates control, moves the styling of the KX112 closer to Kawasaki’s full-sized motocrossers. In addition to the new shroud styling, the rims are coated in black alumite just like the Kawasaki factory team. It’s now available with a MSRP of $4999, check www.kawasaki.com for more.
