296 cm3 39PS fuel injected parallel twin Engine

Fine-atomising injectors (60 μm) ensure ideal fuel delivery at all rpm. Designed for rider-friendly response, the Ninja 300’s fuel-injected Parallel Twin engine delivers smooth, responsive torque at low and medium rpm and hard-hitting acceleration at high rpm. The engine offers significantly stronger torque and power at all rpm, putting the Ninja 300 in a class of its own. Complementing the enhanced engine performance, racing-derived clutch technology offers a lighter clutch lever pull and a back-torque limiting function, while heat management technology like the radiator fan cover directs heat away from the rider, significantly improving rider comfort

Dual Throttle Valves

Similar to the Ninja ZX-10R, dual throttle valves give precise control of intake air, resulting in linear throttle response across the rpm range. Dual throttle valves also contribute to combustion efficiency, and hence engine performance as well as favourable fuel consumption. Larger main throttle valves are and sub-throttle valves help flow a greater volume of air, contributing to the increased engine performance. Fine-atomising injectors with a droplet size of only 60 μm contribute to combustion efficiency.

Assist & Slipper Clutch

Assist & Slipper Clutch was developed based on feedback from racing activities. The clutch uses two types of cams (an assist cam and a slipper cam), offering two functions. When the engine is operating at normal rpm the assist cam functions as a self-servo mechanism, pulling the clutch hub and operating plate together to compress the clutch plates. This allows the total clutch spring load to be reduced, resulting a lighter clutch lever pull when operating the clutch. Assist cam also enables the clutch torque capacity to be increased (to match the stronger engine) without gaining weight. When excessive engine braking occurs – as a result of quick downshifts(or an accidental downshift) – the slipper cam comes into play, forcing the clutch hub and operating plate apart. This relieves pressure on the clutch plates to reduce back-torque and help prevent the rear tyre from hopping and skidding

Sleeveless, aluminium die-cast cylinder

Sleeveless, aluminium die-cast cylinder features plated bores, just like on our Ninja ZX-10R and 6R supersport machines. The cylinder features an open-deck design, offering excellent heat dissipation.

Hard Alumite Coating Piston

Pistons feature a hard alumite coating (on the piston crown and extending past the top land and top ring groove) for increased durability. Piston underside features a groove near the piston edge. The groove directs cooling oil to the rest of the piston underside.

Circuit-developed Diamond Frame

The diamond frame in Ninja 300 features high-tensile steel components (known as special steels which develop high yield, tensile and fatigue strengths, as well as excellent toughness), which offers high strength and high durability – both essential in a high-performance frame.

Heat Management Technology

Large openings in the fairing promote airflow when riding to help dissipate engine heat. Fin design helps direct hot engine air away from the rider for increased comfort. Innovative Kawasaki technology like the radiator fan cover located behind the radiator directs hot air down and away from the rider, significantly increasing comfort when stuck in heavy traffic. Redirecting the air also helps keep the tank, frame and other parts that contact the rider cooler, further increasing rider comfort.

Petal Disc Brakes

Large-diameter 290 mm front petal disc brake operated by a 2-piston caliper delivers powerful braking and a natural feel at the lever. 220 mm rear petal disc and 2-piston caliper give dependable stopping power. Petal brake discs like those on the larger-displacement Ninja supersport models offer excellent heat dissipation

Ninja Styling

Ninja 300 has styling that would not be out of place on our larger-displacement Ninja supersport models. Just like the other machines in the Ninja series, it features a sporty gmass forward, minimalist-tail design. From its aggressive dual headlights to its screen and wheels, the Ninja 300 shares numerous styling cues and design elements from other machines in the Ninja family. One look tells you that this bike is pure Ninja! The Ninja 300 uses a floating-style windscreen with a gap between the cowl and the windscreen. Mounting the screen using only the bolts from the mirror stays contributes to a very clean and elegant design.

Elegant Design

Fine design and large ventilation holes in the fairing have a design similar to that of the Ninja ZX14R.
The design contributes to the Ninja 300's excellent heat management. Aggressive dual headlamp design contributes to the strong Ninja supersport image. The multi-reflector headlamps also offer superb illumination for riding at night. Built-in front turn signals have a sleeker, more unitised appearance.

Modern Instrumentation

Sporty instrument panel design contributes to the advanced-technology and high-quality image of the Ninja series.


37 mm telescopic fork has a revised settings balance for both improved ride comfort on bumpy city streets and a firmer feel when sport riding. Together with the stiffer frame, handling is very smooth and stable. Kawasaki’s original, linkage-equipped Uni-Trak rear suspension delivers stable handling over a wide variety of road surfaces and speed ranges. Like the fork, the rear shock features rebalanced settings for improved comfort when city riding and a firmer feel when cornering.

2-1 exhaust with short-style silencer

Longer, larger-diameter header and centre pipes contribute to stronger performance at all rpm. Short-style silencer with complex cross-section delivers good performance, low noise and plenty of lean angle. Large silencer guard protects passengers from heat and also contributes to noise reduction

Wider rear tyre

Wider 140 mm rear tyre contributes to an enhanced supersport image and offers increased straight-line stability.

Wide set of raised separate handle bar

Wide set of the raised, separate handlebars contribute to the Ninja
300’s easy manoeuvrability.

Supersports style aluminium footpegs

Supersport-style aluminium footpegs give a more direct feel and good controllability when sport riding compared to the rubber covered pegs.
