With a futuristic Ninja style inspired by the powerful Ninja H2, the new 400 offers a modern Ninja design. The large bodywork catches the eye and gives the impression of a larger machine. The high-quality design and excellent fit and finish, comparable to motorcycles in the large displacement class, strengthen this impression. 

Ninja 300 Overview

1. The Ninja 300 has a 296cc liquid-cooled parallel-twin design that offers superior highway passing power and dominant acceleration compared to other lightweight sportbikes.

2. The New Digit Fuel Injection system uses dual 32mm throttle bodies and improves fuel economy and cleaner emissions.

3. The new clutch with the support and slipper functions provides much less power to handle. The design also facilitates the grip to be modulated and reduces the effect of the back-torque when shifting down to reduce wheel hop. 

4. New super sports car bodywork takes its hallmarks from the ZX-10R superbike ninja and raises the sportbike style to the next level. 

5. New 17-inch 10-speed wheels look great, and the back rim has grown wider, making it possible for model 2013 to use a larger 140-speed rear tire. 

6. A new shift drum type for smoother actuation and stronger gear for maximum durability is featured in this revised 6-speed transmission. It offers a wide selection of ratios to match different riding conditions, making finding neutral when stopped much easier. 

7. A special deflector is used by the Kawasaki air management system (KAMS) to channel the heat from the radiator back to leave the engine bottom rather than to be blown onto the rider. 

8. The low seat height of 30.9-inch and tapering for smaller riders boost confidence. 

9. Its high speed was recorded at 180 km/h (112 mph), and its speed in 5.6 seconds was recorded from 0% to 97 km/to 90.58 mph). ABS models had a stopping distance of 38.0 to41.1 m (124.6 to 135 ft) from 97 to 0 km/h (60 to 0 mph). 

10. The fuel-saving of the Ninja 300 was measured at approximately 70 mpg-US (3.4 L/100 km; 84 mpg Alaska). 

Ninja 400 Overview

1. Born out of the world-famous Ninja 250R DNA, the Ninja 400 offers the best Ninja design and style reminiscent of Ninja 650, Ninja ZX-10 R and Ninja H2. 

2. Kawasaki’s newest beast, equipped with a 399cc engine, offers a balance of performance and control. This feature derives from the typical winning Ninja Formula, making it ideal for both new and experienced riders. This duality – the ability to provide a wide range of customers with excitement and ease – will make Ninja 400 the favourite fan on the road. 

3. The turning-over look was always a strong one, regardless of displacement, for Ninja models. In addition to the sharper gaze of the Ninja 400, slim LED headlamps are highly visible and offer considerably higher brightness. They are all features which have low, high beams and an LED position lamp. 

4. The new Ninja 400 is more sharply designed, and the engine is new and updated. The Kawasaki Ninja 400 has been updated with the remainder of the Kawasaki super-sports family. It is designed with design indications from various larger Ninjas, such as the Kawasaki Ninja ZX-10R and the Kawasaki Ninja H2. With new LED headlights and an H2-inspired chin spoiler, the new Ninja 400 certainly looks appealing and more like a middleweight sportbike.

5. The Ninja Super Sports BOON. Ninja 400 defies power, performance, stability, and class-leading handling. Ninja 400 is accentuated as an on-street motorcycle by the driving force across all rotational distances, a uniform power delivery, predictable handling, smooth braking and easy manoeuvring. 

6. The stacked and constantly competitive sportbike class once again has a new leader to be judged by everyone else. Ninja 400 encapsulates the decade-long knowledge of sports bike building the optimum motorcycle that takes all the class leader and fits in with the account for those who want to buy a sports bike of 300 to 650cc.
