2025 Kawasaki KX112: FASTER EVERYWHERE.

Introducing the 2025 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 2025 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 power valve 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 strong low rpm torque, while its piston profile delivers durability and contact surface for the piston ring helping 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 impressive 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 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.

Bridge the gap to full-size bikes with the KX112 motocross bike. We’re pushing the limits with a large 112cc 2-stroke engine on this supermini. Prep your aspiring rider to transition to big bikes with a winning combination of proportionate power, lightweight handling and an optimized chassis.

2025 Kawasaki KX112 Totalmotorcycle.com Features and Benefits

High-Performance 2-Stroke Engine
• Intake and exhaust port timing contributes to the strong low-rpm torque.
• The bridges between the intake and exhaust ports are machine finished for better resistance to seizure.
• The exhaust port window is designed to boost port velocity and the large outlet increases flow for more mid-range and top-end power.
• Carbon fiber reeds aid throttle response. The direction of the fibers is at a 45° angle to tune the flexibility of the reeds for precise response.
• Carburetor settings optimized to match the engine.
• Optional carburetor tuning jets are included so the user can optimize performance based on ridding conditions.
• Long stroke engine contributes to strong lowend torque for holeshot performance and strong drive out of corners.
• Intake and exhaust port timing contributes to the strong lowrpm torque.
• Single-ring piston reduces friction and improves engine response.
• Piston profile designed to help prevent the chance of seizure.
• Contact surface for the piston ring where it contacts the cylinder bore contributes to initial bedding-in performance.
• Resin blocks in the crankshaft boost primary compression pressure for more power, while the crankshaft is weighted for maximum rigidity
and durability.
• Connecting rod length helps reduce the lateral force on the piston for more efficient power generation.
• Exhaust and scavenging port shapes help boost power.
• The cylinder is Nikasil plated for increased durability.
• Large radiator for optimum cooling performance.
• Large water jacket optimizes cooling efficiency.
• Lightweight flywheel with rare-earth magnets enhances low-end engine response.

Kawasaki Integrated Power Valve System(KP)
• [E] Two-piece exhaust valve improves sealing performance and contributes to engine performance.
• The KIPS system controls exhaust port height for increased horsepower and torque.
• Breather in KIPS cover relieves exhaust pressure for more precise KIPS valve action and improved high rpm performance.
• KIPS lever stopper spring absorbs governor “over stroke” for added durability.
• The KIPS governor has a long stroke to open the cylinder valves more fully. A governor spring and 8mm bearing boss add durability.

6-Speed Transmission
• Transmission shafts spline design not only adds durability but also helps make shifting smooth.
• Thrust washer system enhances lubrication and reduces friction.
• Strong gear engagement dogs contribute to a positive shifting feel.
• The ends of the shift forks are hard-chrome finished for durability.

High Tensile Steel Perimeter Frame(KP)
• Sturdy perimeter frame, designed to harness the engine’s power, provides strength and torsional rigidity so that riders can push hard on the track.

Roomy, Adjustable Ergonomics
• Flat seat fits atop fuel tank to allow the rider freedom of movement.
• Handlebar is held by six-way adjustable clamps. Rotating the clamps allows 10mm movement forward, and the height can be raised five or 10mm
by installing one or two 5mm shims between the clamp and triple clamp.
• Radiator shroud design efficiently directs air to the radiator, contributing to cooling performance. The shrouds are also designed to accommodate a wide range of riders and make it easier for taller riders to find a good fit on the bike.
• Shroud and side number plates also help provide freedom of movement.
• The gas tank is positioned to improve handling and lower the center of gravity.
• Wide footpegs for excellent control. Made of cast steel for strength and use 10mm pivots for durability.

• Petal discs reduce unsprung weight and help clean the brake pads for more efficient braking performance.
• Dunlop MX33 tires provide excellent grip, slide control, bump absorption and durability.

BRAKES AND TIRES
Uni-Trak Rear Suspension(KP)
• Rear shock compression damping adjuster has 24 positions and allows damping force to be generated at a slower stroke range for a more stable
feel.
• Shim-type valving for optimum damping control and feel.
• Aluminum swingarm has a brushed finish to match the appearance of the KX250/450.
• Rear suspension settings provide a progressive ride to better resist bottoming and accommodate larger, more aggressive riders. 36mm Inverted Cartridge Fork(KP)
• Shim-type valving for optimum damping control and feel.
• Front fork settings provide a progressive ride to better resist bottoming and fit larger and more aggressive riders.
• Inverted forks are more rigid to provide better steering response and control.
• Compression damping is 20-position adjustable and the cartridge design means better action.
• The aluminum upper fork tubes measure 49.5mm in diameter for flex free performance.

Black Alumite-Coated Aluminum Rims
• Aluminum rims reduce unsprung weight and their strength adds durability.
