#Ninja400

It’s good to be the king. At least, that’s what it feels like to anyone racing a Kawasaki Ninja 400. When it comes to small-bore track or race bikes, what is a field of several – Yamaha R3, Honda CBR500, and KTM RC390 included – has been whittled down to a field of one: the Ninja 400. Virtually anywhere in the world that has a class for little bikes of this size will see a field dominated by the little green machines. Heck, we called it the winner back in 2018 during our Lightweight Sportbike Shootout, too.

What’s the sweet spot for small displacement motorcycles? Is it 250cc? Perhaps 400cc? Ask any internet forum and you’ll likely hear some BS like, 600cc sportbikes are the smallest I would EVER recommend for a beginner. Idiots. Darwinism at its finest. What do we think? We think there are a lot of variables to consider for this question, but the 300cc category is still filled with solid options of bitchin’ motorcycles. Many look at these small-displacement bikes as great options for beginners as well. Which motorcycle is best for a beginner? It all depends on what kind of riding you’d like to do. Any of the options on this list provide a great starting point for new riders. What’s even better is that there are plenty of great bikes in this category that spans multiple genres of motorcycling such as sportbikes, adventure motorcycles, and naked bikes. If you’re interested in entering the world of two wheels check out these great starting points.

We’ve waxed poetic about the Kawasaki Ninja 400 more times than I care to count here at MO. Just check the Best Lightweight/Entry Level category posted a few days earlier to see what we like about the bike. Aside from being a polished, handsome, and fun motorcycle for both new riders and experienced veterans alike, what we didn’t mention in the Lightweight/Entry Level piece was just how affordable the little Ninja is. Ranging in price from $4,999 to $5,499, depending on color choice and ABS, the 400 is easily accessible for students on a budget – we’ve even had readers report dealer markdowns in their area on the Ninja 400.

The Lightweight category of motorcycling is growing like a wildfire, with tons of cool bikes that offer style and performance that’s readily accessible for a new or inexperienced rider. But to us, the motorcycle topping the list of all those competent performers is the Kawasaki Ninja 400. Some May claim that the “small-displacement” moniker no longer applies, but to get hung up on 100cc is a waste of time for what’s otherwise an excellent motorcycle. The increase in size from the previous Ninja 300 brings with it a modest bump in power suitable for newbies, but also entertaining for experienced riders. Combine that with styling inspired by its bigger Ninja siblings, and new riders no longer have to feel self conscious about their beginner bike looking dated and ugly. This, in turn, helps keep riders from graduating to bigger, sexier machinery they may not be ready for.

The Kawasaki Ninja 400 will soon be joined by a naked version, as the California Air Resources Board has certified a model bearing the designation ER400DK for 2019. Kawasaki has long used “ER” code for its naked Twins, and the new model will likely be sold as the 2019 Kawasaki Z400.

In case you haven’t figured it out by now, we – err, at least I – really love the Kawasaki Ninja 400. Ryan came off the bike at its press intro and was happy as could be. He’s such a fan that he pointed out the 10 things he specifically likes about it. Then, once we stacked it up against the KTM RC390 and Honda CBR500R in our 2018 Lightweight Sportbike Shootout, the Ninja 400 came away a winner, yet again. As far as lightweight sportbikes go, this one is sweet. It’s a great entry-level motorcycle for the new or returning rider, but has plenty of performance for the experienced rider to exploit.

You’ve heard the adage a lot if you’re a consistent Motorcycle.com reader – it’s more fun to ride a slow bike fast than a fast bike slow – and with our recent Lightweight Sportbike Shootout we’ve gone ahead and proved it. By now we’ll assume you’ve already read the shootout, seen our conclusions, and also drawn your own; but what exactly do these three motorcycles look like at speed around Laguna Seca? This is your chance to see for yourself, as we’ve captured a quick lap aboard all three bikes, courtesy of Yours Truly.

It’s getting to be a bit silly what’s passing for a lightweight sportbike these days. In the beginning, it made sense: You had the Kawasaki Ninja 250. And, well, that was it. It only took twenty-odd years, but the other manufacturers eventually took notice that building small bikes to entice new or returning riders was probably a good thing for the industry, and hence, started building little bikes of their own. Honda came around with the CBR250R…just as the competition upped the ante again. Kawasaki pushed the bar with the Ninja 300, then Honda made a weak attempt to follow suit with the 286cc CBR300R. Yamaha then jumped in the game, shoving displacement rules out the window with its 321cc R3 – but not to be outdone, the brash Austrians (via India) at KTM one-upped all of them with the 373cc RC390.

When Kawasaki redesigned its smallest Ninja for 2018, the engineers went back to the drawing board and while the motorcycle on your screen may look like a revision in styling, the Ninja 400 has, quite literally, undergone changes from the ground up.

Kawasaki may have just found the sweet spot with its new Ninja 400. At a glance, the new motorcycle has undergone a substantial weight reduction treatment, a displacement boost of 103cc, and a sexy styling redesign – all while remaining at the exact same price point. Non-ABS models start at $4,999 while ABS is an additional $300. Kawasaki was out for blood when it went back to the drawing board for its new entry-level motorcycle.

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.

This news slipped under our radar last month, but when the Kawasaki Ninja 400‘s European debuted at EICMA, the World Superbike Championship announced the new model will be eligible to race in the series’ relatively new World Supersport 300 class.

After unveiling the Ninja 400 at the Tokyo Motor Show and seeing it again in Milan at EICMA, Kawasaki officially announced the new 399cc sportbike for the U.S. market. Impressively, American pricing starts at $4,999 for the 2018 Kawasaki Ninja 400, the same MSRP as the outgoing Ninja 300 (the ABS version is also priced similarly, at $5,299). We’ll also see a KRT edition color option (with ABS) in dealerships carrying a $5,499 price tag.
