How Much Power Does The New 2018 Kawasaki Ninja 400 Make?

Kawasaki’s littlest Ninja is a cornerstone of motorcycling, and for 2018 it’s been overhauled from top to bottom. We reviewed the bike in detail in this First Ride article, but we were only able to estimate the bike’s power with our butt dyno while at the press launch. Now, however, we’ve run it on an actual dynamometer, and the results are impressive.

The Ninja 400 puts 43.4 hp to the ground at 9,900 rpm, backed up by 24.6 pound-feet of torque at 8,250 rpm. That's real-deal, rear-wheel horsepower, folks, and the new bike's curves tower over the outgoing 300's output.

The 2018 bike obviously benefits from more displacement, but there are other things that contribute to the increase in power including higher-compression pistons, new cams, and a totally revised intake and exhaust system.
