Overall ratingNext up: Ride & brakes
Kawasaki’s new Ninja 400 is a genuine sports bike in every respect; it has character, great handling and a superb engine. It’s also light and comfortable enough to be a useable all-rounder. It may be A2 friendly, but that shouldn’t stop someone with a full licence giving serious consideration to a test ride.
The old Ninja 300 couldn’t haul itself through Euro4, so was killed off to make way for this new Ninja 400, boasting greater performance than its predecessor from an all-new engine and chassis – the net effect being a claimed weight saving of 8kg.

Although the suspension is non adjustable (barring rear preload) it’s no real loss as Kawasaki have got the set-up spot on. The forks have been beefed up from 37mm to 41mm giving a firm and precise ride that verges on plush around town and overall balance is excellent thanks to the new weight saving trellis frame.

The perky 399cc engine is the Ninja’s raison d’etre and it’s a gem. Along with extra cubes comes a hike in performance to 44.3 bhp and 38 Nm of torque, which adds up to an eager, flexible mill with bags of character. There’s enough grunt for overtaking (just) and with a top speed over the ton, it can hold its own on the motorway too.
Reliability & build qualityNext up: Value
Kawasaki’s reliability is practically beyond question these days, and if looked after, the Ninja 400 should be pretty much bomb proof. Fit and finish is in line with far more expensive models and the overall feel is of a quality item.
Value vs rivalsNext up: Equipment
The pricing sits neatly within Kawasaki’s model range and puts the Ninja 400 on a par with its closest rival, the Yamaha R3, at the top end of the lightweight/A2 friendly class. Build quality, performance and fun should make it a solid buy for the money (£5499). Although the Yamaha is a couple of hundred quid cheaper, the Kawasaki packs another 100cc and has a few more horses than the R3's 41bhp.
The Ninja 400 replaced the 300 in the UK and was aimed at keeping it ahead of its main rivals.
As you're upping the cubes a bit with the Ninja 400, the Honda CBR500R also becomes something of a rival. Although the bigger Honda comes in at £6099 it offers 47bhp and a pretty intoxicating mix of power and poise (for a 500cc machine). The Ninja 400 has certainly got its work cut out against some serious rivals, but for those who like a mix of sporty style and practicality, the Kawasaki will tempt many.
As an entry-level sports bike the Ninja 400 may not have everything, but what it does have is top notch, such as lightweight Nissin brakes and an LCD panel to display speed, fuel, trip, mpg and a very useful gear indicator. A taller screen and similar seat are available as extras, as is a tank bag and 12v accessory socket.
It looks great too.

Version: Ninja 400 Performance
Bought this bike 3 weeks ago as my third bike (Already have a Kawasaki Ninja 650 and H2 SX). Always been a fan of small capacity lightweight sports bikes and the Ninja 400 replaced a Ninja 250SL. This bike is definitely more than I expected it to be, it's as fast as you really ever need. It is very light and flick-able and really makes you giggle when riding although equally is easy to ride in traffic and if your'e in the mood for an evening chill ride. mpg currently just over 70 so you really can't complain. My only niggle with the bike is that the seat is a bit hard, it's not uncomfortable but really isn't what I'd call a long distance seat. Drayton Croft Kawasaki in Hinckley have supplied all three of my bikes and it was on their recommendation I looked at the 400, definitely glad I did. I hear the Ninja 400 constantly called a beginners bike and while it is great for you to start your sports bike journey on it is so much more than that. I would suggest any seasoned riders out there looking for something small and or a second bike to play on to seriously consider this bike and it is 100% worth a test ride.
Overall not bad at all, handles bumps ok, possibly a bit soft for some but I don't have issues. Not a bike I would take a pillion on even though it is possible.
No problem at all here, smooth and quiet when your'e not in the mood and a great sound when you are, I have performance model so has Akrapovic exhaust is standard which helps. Engine pulls in all gears and is flexible even at low speeds, there is a definite surge around 7k and pulls well all the way through to the red line. Although motorway speeds are easily obtained, 6,700rpm at 70mph means its not really a long distance motorway cruiser.
Only had the bike for a short period so hard to tell but if my other two bikes are anything to go by then all will be good
Again, a bit early to say and let's face it we'd all like to pay as little as possible for a bike and servicing, but price is on par with rivals and I've always had a great deal.
Very back to basic bike apart from adjustable rear suspension but it is expected. Would like it if brake leavers were adjustable, not a real problem, but then I have fairly big hands, may be an issue if your hands are on the small side.
Buying experience: Always have great service from Drayton Croft in Hinckley and always a great deal. Always friendly and I would always buy a bike from main dealer. Have to say though not all Kawasaki dealers are equal, I ride 44 miles to them because dealers near me in Worcestershire leave a lot to be desired.
I would definitely recommend the bike to any beginner or lady rider. It is very economical and a stunning bike that you won't get bored with quickly.
The ride is smooth and comfortable, but the brakes are not as good as I would like them. If you have to ride fast you will not stop it quick in an emergency.
More than enough power for the beginner and good power delivery when changing gears in mid range revs.
The ABS brakes is a big plus on the bike for safety. I would definitely invest in some steering damper, cause the bike is moving too much over the road with every small movement you make on the bike.
Buying experience: The dealer was very thorough with explaining all the details and features of the bike.
Ideal first bike!
A very decent all rounder. My first bike, very pleased with it. Lovely to ride, predictable and feels spot on in the bends, love it!
All good so far, fast enough to entertain but not stupidly quick, spot on for a newbie like me!
So far so good!
Averaging around 65mpg!
Nice layout, switch gear etc. Gear indicator, fuel range & mpg nice to have!
Buying experience: Bought new from Kawasaki Dealer, no complaints.
