2020 Kawasaki Ninja 400

The 2019 Kawasaki Ninja 400 builds on the popularity of the previous Ninja small-displacement motorcycles and continues to impress.

 2020 Kawasaki Ninja 400


The 2020 Kawasaki Ninja 400 continues upon the success of its small-displacement predecessors: the Ninja 250R and Ninja 300. The Kawasaki Ninja 400 represents Team Green’s effort to attract beginner motorcyclists to its brand, while also satisfying experienced riders with a capable all-around motorcycle. Sharing the same engine and most of the same components, the Kawasaki Z400 is the naked, or standard-style, version of the Ninja 400 with a tubular handlebar and more upright seating position


Kawasaki increased displacement in the 1992 Ten Best Bikes Under 500cc Streetbike winner, Ninja 250R in 2013 to produce the Ninja 300, and in 2018 for the Ninja 400, refining its small sportbike over the past three decades. This culminated in 2018 with the Kawasaki Ninja 400 winning Cycle World’s Ten Best award in the lightweight streetbike category.


The Kawasaki Ninja 400 bears the Ninja moniker, meaning that it falls within Kawasaki’s sportbike line. Other models in Kawasaki’s sportbike line are the Ninja 650 and Ninja 1000. In the supersport line are the Ninja ZX-6R, Ninja ZX-10R, and Ninja ZX-14R. In Kawasaki’s hypersport line are the sport-touring supercharged Ninja H2 SX, Ninja H2, and track-only Ninja H2 R.

How Much Power Does The Kawasaki Ninja 400 Make?

The 2020 Kawasaki Ninja 400 houses a 399cc DOHC parallel twin engine. Kawasaki claims the engine produces 45 hp (33.56 kilowatts) at 10,000 rpm and 28 pound-feet of torque at 8,000 rpm.


 On our in-house dyno, the Kawasaki Ninja 400 produced 43.4 hp (32.4 kilowatts) at the rear wheel with 24.6 pound-feet of torque at 8,250 rpm.


That’s a 3.6 percent difference in horsepower from what Kawasaki claims. This falls within the expected range of a 10 to 15 percent difference because of how crankshaft horsepower and rear wheel horsepower is measured.
