So, you've got the itch. You want a Ninja. Specifically, you’re looking at the Ninja 400, which has basically become the "gold standard" for anyone starting out—or just anyone who wants a bike that doesn't feel like a heavy boat in the corners. But here is the thing: if you walk into a Kawasaki dealership today looking for a brand-new 2026 Ninja 400, you’re going to have a weird conversation.
Why? Because the 400 has officially passed the torch.
In 2026, the Ninja 400 is effectively a "used market" king. Kawasaki shifted their main production focus to the Ninja 500 (which is actually a 451cc engine, but let’s not get bogged down in math yet). However, because the 400 was so incredibly popular, the market is absolutely flooded with them. Whether you're looking for a leftover "new-old stock" unit or a pre-owned gem, the price tag varies wildly depending on how many times the previous owner dropped it in their driveway.
How much is a Kawasaki Ninja 400 right now?
Honestly, the price depends on your patience. If you're looking for a used model—which is where 90% of Ninja 400 buyers are hanging out these days—you’re looking at a range of $3,800 to $5,800.

I’ve seen high-mileage 2018 or 2019 models go for as low as $3,500 if the fairings are a bit scuffed. On the flip side, a "mint" 2023 or 2024 model with ABS and under 2,000 miles can still command $5,500 or more. People love these bikes. They hold their value surprisingly well because there’s always a fresh crop of new riders looking for exactly this machine.
The "New" Alternative: The Ninja 500
Since the 400 isn't the "current" flagship small-displacement Ninja anymore, you might be tempted by its successor. The 2026 Kawasaki Ninja 500 starts at an MSRP of roughly $5,399 for the non-ABS version. If you want the fancy KRT (Kawasaki Racing Team) colors or the SE version with the TFT display and LED turn signals, you’re pushing closer to $6,400.
It’s a bit more expensive than a used 400, obviously. But you get a warranty. And that "new bike" smell, which is mostly just hot plastic and oil, but still.

Breaking Down the Total Cost of Ownership
Looking at the sticker price is a rookie mistake. Buying the bike is just the entry fee. To actually get on the road, you need to account for the "hidden" stuff.
- Insurance: This is the big one. For a young rider, insurance on a "sportbike" (even a small one) can be a gut punch. Most Ninja 400 owners report paying between $300 and $500 per year for full coverage. If you're over 25 and have a clean record, it’s cheap. If you're 19 and have a speeding ticket? Good luck.
- Gear: Do not spend all your money on the bike and then buy a $50 helmet from a gas station. Budget at least **$800 to $1,200** for a decent ECE-rated helmet, a jacket with armor, gloves, and boots.
- Maintenance: One of the reasons the Ninja 400 is so beloved is that it’s hard to kill. An oil change will run you about $60 if you do it yourself. A set of new tires (you’ll need them every 6,000 to 8,000 miles) will cost about $250 to $400 including labor.
The Hidden Costs: Dealership Shenanigans
If you do find a "new" leftover Ninja 400 at a dealer, the price on the tag is a lie. Well, maybe not a lie, but it’s definitely not the final number. Dealers add "Freight and Setup" fees.
In 2026, these fees usually add another $600 to $900 to the price. Then there's doc fees. Then tax. And title. Suddenly that $5,299 bike is **$6,800 out the door**. This is why the used market is so competitive. Buying from a private seller means you skip the "prep fees" and usually just pay the agreed-upon price plus whatever your local DMV charges for the title transfer.

The ABS Tax
When you're shopping, you’ll see "ABS" and "Non-ABS" models. Honestly? Get the ABS. It usually adds about $300 to $500 to the price, but it can literally save your life if a car pulls out in front of you on a rainy Tuesday. It also makes the bike much easier to sell later.
Is it still worth it in 2026?
You might wonder if you should just skip the 400 and get the Ninja 500 or even the four-cylinder ZX-4RR.
The ZX-4RR is a different beast entirely. It’s a screaming, high-revving track weapon that costs nearly $10,000. Unless you have a specific desire to hear a 15,000 RPM exhaust note every morning, it's overkill for a commuter.
The Ninja 400 remains the "sweet spot." It’s light. It’s narrow. It handles like it can read your mind. Even with the Ninja 500 out, the 400 doesn't feel "old." It feels refined.
Actionable Next Steps
- Check the Vin: If you're buying used, run a VIN check. These bikes are often used by learners, which means they might have been dropped or crashed and rebuilt.
- Get an Insurance Quote First: Before you hand over a single dollar, call your insurance agent. Give them the year and model. You don't want to buy a $4,000 bike only to find out the insurance is $2,000 a year.
- Inspect the "Consumables": Look at the chain, the tires, and the brake pads. If the chain is rusty and the tires are squared off, use that to knock $500 off the asking price. You’re going to have to spend that money immediately anyway.
- Look for Stock Exhausts: A bike with the stock exhaust usually means the owner didn't mess with the engine mapping. It's often a sign of a more "gentle" ownership history compared to a bike with a loud slip-on and a fender eliminator kit.
The Ninja 400 is an iconic machine for a reason. Whether you pay $4,000 or $5,500, you’re getting one of the best-engineered small motorcycles ever made. Just make sure you leave enough in your bank account for a good pair of gloves.
