Kawasaki 2019 Ninja 400 vs Yamaha 2019 YZF-R3 – Comparison Review

The Kawasaki Ninja 400 is best for its performance in small-displacement super sports segments. It has got a power parallel-twin 399 cc engine packed in tubular-steel chassis. The reason behind its success is lightweight Ninja’s title of the best on-road seller in the entire Kawasaki lineup. At the same time, it offers riders more room for aerodynamic changes claimed to make it 7-percent more slippery plus raise top speed by 5mph. On the other hand, the Yamaha YZF-R3 features 321cc parallel-twin engine that is unchanged but the bike contains 37 mm inverted KYB fork including LCD dash and aggressive ergonomics.

Well, most of the motorcycle users use bikes for the mode of transportation. Still, both of the companies have not given any sort of city riding information regarding these bikes. So, we will only focus on the racing aspect of both of these bikes. But moving towards the ground, let’s have a look at both of these bikes on-page. It clearly shows the Kawasaki has the advantage of 78 cc displacement. The Kawasaki can easily harness 43.4 hp at 9,900 rpm and 24.7 pound-feet of torque at 8,300 rpm while the Yamaha YZF-R3 can deliver 36 hp at a higher 10,700 rpm and 19.8-pound feet of torque at 9,000 rpm.

Let’s have a look at the torque chart of both of these bikes, the Ninja’s torque curve is steeper in its midrange, and it pulls longer after peak output giving useful over-rev and more flexibility in shift points. Riding a Kawasaki is like riding a missile. On the other hand, the torque curve of Yamaha YZF-R3 is flatter as compared to Ninja and the power drops off more dramatically. So, Ninja 400 takes the lead here by giving out eight mph quicker than Yamaha on straight race.

With just a minor twist of a throttle, Ninja can quickly produce the power above 7,500 rpm giving enormous speed leaving R3 far behind. It indicates that the YZF-R3 will have to keep the momentum in the higher revs; otherwise, it will be out of the race. But still, that’s fine for the bike having 321cc engine fighting against 400class bike.

In terms of handling, the Ninja is not as good as R3. It is because of the massive power that it is not easy to handle. On the other hand, YZF-R3 gives a comfortable handling experience. It is because of R3’s superb front-end feel that gives perfect riding pleasure.

The Ninja has good braking results on the track. Although riders never apply 100 % of the brake during the race still Ninja gave excellent results. But Yamaha YZF-R3 has some other characteristics that make it amazing. Its stiffer fork is a bit higher in its stroke, so it allows the rider to know exactly how much brake presser is being applied and how much is left. The Ninja does not provide the same feel but it has excellent braking power.

Although the Kawasaki Ninja 400 is a bit difficult to ride, it gives an incredibly fun ride. Its power, slipper clutch and superb handling is an ideal platform for inexperienced riders who wants to learn more. Moreover, it provides good riding pleasure in city traffic as well. Just sit back and don’t give much of a throttle. Its softer suspension is considered to be best on the road, soaking up all the bumps.

The Yamaha YZF-R3 has a short first gear that makes it easier for the new rider, but its second shift requires a rapid change. It needs a large clutch slipping if the rider wants to be in the race. It has a big sixth gear and thanks to the superior wind protection that offers maximum comfort at highway speeds.
