Kawasaki Ninja 400: The Ultimate Sportbike for Enthusiasts

Are you a motorcycle enthusiast searching for the perfect sportbike that offers both style and performance? Look no further than the Kawasaki Ninja 400. This powerful machine offers an exceptional riding experience, with a sleek design and impressive capabilities that make it a standout in its class. In this article, we’ll dive into what makes the Kawasaki Ninja 400 a top choice for riders looking for a high-performance sportbike.

Design & Finish Quality Kawasaki Ninja 400

Out of the 3 cars I have had a lot of contact with, R3, Ninja 300 and RC390, I rate the finishing quality of R3 the highest, the Ninja 300 a bit lower and the worst one, the RC390. R3 is beautiful because in addition to the rather aggressive shell, there is less space on the body, it looks much stronger than the Yamaha R15 juniors.

The details of the fuel tank cover, car cover, side cover are all made of plastic, looking nice and sharp, but when turning the car or pressing the thighs on the sides of the fuel tank, a creaking sound can still be heard.

In the European market, Kawasaki has just added a white color (Pearl Blizzard White) to the Ninja 400 sportbike model. Since its launch in 2018, the Ninja 400 has only been available in two colors, blue and black and this is the first time in the line. This sportbike has been added by Kawasaki with a very personal white shirt.

The new color of the Kawasaki Ninja 400 will come with all white parts around the car from the front cover, front fenders, side skirts, rear seat covers and fuel tank. To make the bike look too bland, Kawasaki added ” Kawasaki Ninja 400 ” stickers to the side panels.

Except for the new paint color, the Kawasaki Ninja 400 ABS 2021 retains the same design and equipment, but the performance is reduced by 1 horsepower compared to the previous models. Kawasaki Ninja 400 ABS 2021 continues to be powered by a double-cylinder DOHC engine block, liquid-cooled, direct fuel injection with a capacity of 399 cc.

However, this engine block only produces a maximum capacity of 47 horsepower at 10,000 rpm instead of 48 horsepower like its predecessor, while the maximum torque remains the same at 38 Nm. from 8,000 v/min. The engine is combined with a 6-speed gearbox, comes with an anti-slip clutch system when folding (Slipper Clutch) and meets Euro 4 emission standards.

The suspension of the 2021 version is still a 41 mm telescopic fork in front and a custom single shock absorber at the rear with 5 levels. Similar to its predecessor, the car uses disc brakes on both wheels, including a 310 mm diameter disc at the front, a 220 mm disc at the rear combined with ABS brakes. 14-liter fuel tank, 17-inch single 5-spoke wheels. Unladen weight at 167 kg, ground clearance 140 mm and seat height 785 mm.

Sitting posture Of Kawasaki Ninja 400

Although it is a Sport car, the sitting position of the R3 is quite straight, almost as straight as Naked cars or popular cars like Exciter… This helps you not to feel tired back and wrists when driving, especially on long journeys. I’m riding a Naked but when I switch to R3 I still feel very comfortable with the sitting position, not much different from my Naked.

Taper feel, number

The handle is soft but a bit heavy. Soft means you squeeze the clutch in very easily, and heavy means holding the clutch for a long time will be very tired. Running normally, it’s not a problem, but when I get stuck in traffic, I get tired because my hands have to squeeze the clutch very tired.

The R3 gearbox has 6 speeds, the same way of hooking the number as the Exciter, 1 forward 5 reverse. The number of hooks is light, at first not familiar with the car, so the hook is easy to make a toad sound that is very painful to the car. After running for a while, starting to get used to the feeling of gears with more speed, the gearshift will be smoother.

Feeling of driving + leading Of Kawasaki Ninja 400

The body of the R3 is quite long (2.09 meters), so turning the car in a small alley is a bit difficult. Fortunately, the steering angle of the handlebars is quite wide (wider than the CBR150), so turning or cornering is also more comfortable.

While cornering or turning, even though it is a Sport car, the wide steering angle of the R3 will give you the feeling of riding a Naked-bike or a normal car. You do not need to hug wide and do not feel difficult to control the front of the car.

The R3 does not have a rear handle like the CBR300 and CBR150, so you have to take more effort to pull the car in and out of the parking lot. In addition, the weight of the car is also relatively light (wet TL is 169 kg), so it is not difficult to tow.

Feeling of running + Acceleration

1st gear seems a bit sluggish (at the time of starting to pull the throttle), 2nd gear is a bit better, 3rd gear and 2nd gear are the two most comfortable city driving levels but not smooth, through 4th gear is clearly smooth .

Even so, the acceleration of the R3 is very admirable (see details in the power section below).
After a few minutes of getting used to the car, I started to try to slow down by pulling on the throttle right from 1st gear. Because in 1st gear, the car is not too loaded, so pulling the throttle a little bit will help the car jump up but still lie down. stay under your control, without being caught by a sudden out-of-control car situation.

During this rodai period, the car’s gears are short, although I tested #1 to a maximum of 64km/h, #2 to 89/km/h, but the engine roared quite early, just running up to about 30km/h. h is that the car has started to have a slight rumble, which means the engine starts to vibrate enough to make your butt, thighs and hands feel the vibration of the car.

Of course, I have to immediately switch to a larger gear or 3 to let the engine calm down and continue running. If I drive smoothly in the city, I go in 3rd and 4th gear, that’s why I say the car’s speed is short, meaning that each gear can’t run much if you want to run smoothly.

The problem of machine screaming and slight vibration can be from many factors, but mainly from the engine. Normally our car only has 1 cylinder, inside there is a piston running up and down to generate work, while a 2-cylinder car has up to 2 pistons running up and down, so they will create many problems. more vibration, making the car vibrate more than a single cylinder car. In addition, because it is still in the rodai period, most cars are often not smooth, the engine parts are not yet all friction, so there is often a phenomenon of hotter, more screaming and vibration than the finished rodai car.

Power R3

​The acceleration of R3 is very good. 1st gear can max 64km/h, 2nd gear gets 89km/h. From 0 to 60 km / h takes about 2.67 seconds and 0-100 km / h about 5.99 seconds. The maximum speed is more than 180 km / h but I have not tried it. Tested to 120 km / h but the car is still very compact and stable, there is no shaking phenomenon.

A huge disadvantage of the R3 when compared to rivals Ninja 300, RC390 and CBR300 is that there is no ABS brake. Actually, the R3 has ABS, but the version sold in Vietnam is not for the purpose of reducing costs. Thanks to that, the price of R3 in Vietnam is very good compared to other competitors. ABS brakes help the car to prevent slipping and prevent wheel spreading when braking sharply or braking on slippery or wet roads.

When there is ABS brake, the driver will feel more secure when driving on the road as well as running at high speed, while for R3 without ABS, when encountering an emergency braking situation will require the driver to have a lot of experience in handling. more brake.

In the inner city with beautiful road surface, braking is not difficult with R3, as long as you know how to combine the two front and rear brakes, the braking performance of R3 is also very good, no different from other cars. from small to large. And if you only use the rear brake, the car will easily slide forward and that’s not what we want at all.

Yamaha R3 attracts us by its too good price, sacrificing ABS for a price of 150 million. If temporarily putting this issue aside, among the four typical representatives of the 300cc line, R3, Ninja 300, CBR300 and RC390, I prefer R3 for the following reasons:
Price is acceptable.
Nice design, light car.
2 cylinders for a more even sound than a car with only 1 cylinder.
The engine is very powerful, only losing to the RC390.
The sitting position is very comfortable.

As far as I know, the technicians in Yamaha’s Town are equipped with knowledge of R3 as well as spare parts ready to support new customers buying cars. Kawasaki’s Ninja 300 and KTM’s RC390 also have an official dealer and full support, only the Honda CBR300 has just been imported through the dealer, so there is no official support from the company.
