2018 Kawasaki Ninja 400: Exclusive Dyno Run and Measured Weight!

Looks great. I think some R3 owners are going to be mighty tempted.

That's awesome! Good to know that the cbr 500 is just barely ahead of its curve but cost so much more, and doesn't look nearly as cool
Thanks for sharing that mate. What was the 'measured weight' they mention?

366 pounds.

So what's the deal with Motorcycle.com retracting the article, the bikes are for sale and people have them on multiple continents now.

Good thing you at lest posted up the images because the article seems to be completely missing from the site. Maybe they're saving the article for their physical publication? Weird to retract it and the act irks me...Was so excited to see the link and now it's gone.

I agree. It's bad enough that it's taking so long for dealers to get these in and now we can't even drool over the stats? It would be one thing if it never showed up, but to get posted and then pulled!? It's like kawasaki is toying with us.
From what I read before it got taken down, it said that the 400 has slightly more HP and slightly less torque than the cbr500 (both numbers were within 1 or 2 of each other) but the Ninja is about 70lbs lighter. I think the abs ninja weighed in at 366 wet on their scale.
It's probably more that they don't want to advertise figures that haven't been fully confirmed. Or maybe Honda was worried about how well the Ninja 400 is performing and was like "hey don't take away customers with that new bike that hasn't even seen a worldwide release yet." Those are very impressive stock figures and its definitely possible for the Ninja to match/surpass the CBR with some tuning.
Betcha it was removed by a hacker who was secretly hired by Honda! :smile_big::devil:

2018 Kawasaki Ninja 400: Exclusive Dyno Run and Measured Weight!
The small-displacement sportbike class gets one-upped

Kevin Duke | February 5th, 2018 | 4 comments | Print | Email a Friend

Kawasaki’s all-new Ninja 400 is ready to upend the small-displacement sportbike category by offering the triumvirate of appealing motorcycle characteristics: class-leading power, a reasonable price, and swanky good looks.

At a base MSRP of $4,999, the new 400 retails for the same price as the previous Ninja 300, and the 400 is also endowed with a seriously attractive profile. But we already knew that when the Ninja 400 was announced.

What we can exclusively report now is the Ninja 400 produces more power than anything in its class, cranking out a considerable 44.0 horsepower at its rear wheel. Its torque is also healthy, at 25.0 lb-ft when run on the Dynojet 250i at our friend’s shop, Mickey Cohen Motorsports.

Of course, the Ninja 400 is armed with more engine displacement than all but one of its rivals, so it brings a size advantage to the table. But a bike with a bigger engine and similar weight priced at the same or similar MSRP threshold is a net gain. Full of fuel (3.7 gallons), the ABS-equipped Ninja 400 scaled in at 366 pounds, which compares favorably to the claimed wet weight of the 321cc Yamaha R3 ABS (375 lbs) and 384-lb Ninja 300 (with 4.5 gallons of fuel).

Perhaps most appealing is how Kawasaki was able to hold the line on pricing, selling for the same MSRPs as the Ninja 300, at $5,299 for ABS. The sharp-looking KRT edition colorway retails for $5,499 and includes ABS.

For context, Yamaha’s base-model R3 also retails for $4,999. Honda’s CBR300R is cheaper by $300 but is down an enormous 18 horsepower. The CBR500R, while close in power to the Ninja 400, costs much more ($6,599) and weighs a massive 59 lbs extra. KTM’s RC390 retails for $5,499 but includes ABS as standard, and it weighed 364 lbs last time we tested it.

In its brief time in our hands, the Ninja 400 was ridden only to and from the dyno by Sean Alexander, who, at 6-foot-2 and more than 250 lbs, isn’t the ideal candidate for a smaller sportbike. That said, Kawi’s 400 impressed him with its relative vigor, accelerating on an uphill freeway section to 105 mph while sitting upright. In a tuck on a downhill road, he saw 127 mph on the speedo and estimates an actual 120-mph top speed. He said it felt stable at speed but didn’t feel especially nimble. Brake feel, he says, was linear.

While we never know for sure how a comparison test is going to turn out before we ride the bikes side by side, unless Kawi messed up the adroit handling of the Ninja 300, the new Ninja 400 is a solid bet to take the top honors in our 2018 Lightweight Sportbike Shootout.

Our boy Ryan Adams will be testing the Ninja 400 on street and the racetrack this week, so be sure to stay tuned to MO for his report.



[The dominance of the Ninja 400’s engine (dark green trace) is evident in this horsepower chart, dwarfing its 300cc competition and revving to a top-end pull that even surpasses the output of Honda’s 471cc CBR500R. Note also how the Ninja keeps pace or exceeds the 373cc Single of KTM’s RC390.]



[Small-displacement sportbike engines are generally known for weak torque production, but the Ninja 400 is going to change that assumption.]



[Exclusive Ninja 400 dyno run shows a lot of ponies and an impressively flat torque curve from its 399cc parallel-Twin motor. That’s nearly a 30% increase in horsepower over the Ninja 300!]



[The Ninja 400 is also available in this Pearl Solar Yellow/Pearl Storm Grey/Ebony colorway.]

This guy says around 3:45 that he was track riding with Ari and other journalists, so reviews should be pouring out soon I'd guess.


I'm not familiar with this YouTube channel, but it sounds like Ari Hennings voice reviewing the track performance of the 400. He seems impressed!
Ari also posted some great on-board track footage on his Instagram. I'm not sure how to embed the video, but the link is below.

It occurs to me that those of us getting the restricted power version 400 are waiting on dyno charts for that to see how they differ from the full power US spec.
the Thailand bike is hitting 45.5 hp on the dyno all stock and running 28ftlb aka 38nm of torque which is higher than wats stated on motorcycle.com's dyno and is exactly what kawasaki has on the spec sheet which still looks restricted to me

If that Thai bike is hitting 45.5 HP @ the rear wheel then that is more than the claimed Kawasaki figure of 45 HP @ the crank. Also, if you look at the inlet air temp on the dyno it is reading 32 degrees and we all know heat robs power, so that motor is a goer!

Wow, maybe there are two categories of power output bikes for the Ninja 400 - the single ECU limited unit supplied for testing to authorities in bhp restricted jurisdictions, and every other Ninja 400 ever produced!!!

Just to confirm Kiwi Rider, Thailand is one of the countries supposedly getting the 'ECU restricted' 45HP model which is the same as NZ?

Yeah I've been wondering about this myself ever since seeing that Dyno read out. It's only Aussie, NZ, Europe and the UK that have the learner licence restrictions so maybe Thailand is 'full power'.
Unfortunately the Kawasaki Thailand web site does not offer an engine output figure:
