"The sound that this bike makes is so much fun. It makes you feel like you're going way faster than you actually are." THIS is what I feel every time I'm out in twisties on my ZX-25R. Feel like you're slaying everything and you're only going 70 km/h hahaha
Thats one thing some riders laugh about but I personally find that as a bonus. Going high revs without risking turning into street paste is a plus on my books.
Good video. I have an R6 and RC51 and they are both insanely fun but the whole point of me buying the zx4rr is to get that same feeling but at much safer speeds. If I want to scare myself I'll jump on the RC51.
Great review! Kudos to Kawasaki for keeping this sport segment exciting when most other manufacturers are concentrating on their adventure bikes. Looking forward to seeing the update Kawasaki will bring to the ZX-6R next month!
Zx4rr stock is only 52 HP in the US. Why didnt you mention yours was reflashed in the video? You should mention it in the description box. Otherwise great review.
I think you should explain that you have to flash the zx4rr ecu and void the warranty to get it to its full potential. Otherwise it’s real similar to the 400.
Are you really worried about a warranty on a 10k$ track bike? Even if it was stock, they would likely give you a hard time because of the track use. And a flashed ecu doesn’t necessarily void the warranty on non-drivetrain items.
The Zx4RR is designed to rev to 16k RPM. The USA/Canada version is detuned to 11.5k RPM. Reflashing it to rev to 16k is not bad for the bike, it simply allows it to work as designed.
Id like to see a track time comparison between the zx4rr and a zx6r. With the zx4rr only weighing 15 pounds lighter than the zx6r, I can't imagine it's any quicker in the corners.
Also zx4rr isn’t any lighter than a GSXR 600. I get some newer riders don’t want 600cc SS power, but I don’t see any real benefit for an experienced rider to choose the zx4 over a 600.
@@sandersho4008 the zx6 is being re-launched with a bit less power and a bit less revs…it will have the same THREE heavy catalytic converters at a MINIMUM, possibly bigger/heavier ones. Expect the new ZX6 to be even heavier now that it will have all the same electronic features AND MORE than the ZX4, plus bigger and heavier wheels and tires and bigger discs etc. Just as with the GSXR , it’s not really fair to be comparing a new for 2023 bike with an old design that hasn’t had to update all the tech and emissions crap yet
@@sandersho4008 if you don’t get It you’re not paying attention because everyone interested in this bike says the same thing. It’s in this video and in the comments and everywhere. They want to enjoy the 600cc inline 4 sound & experience while at much lower speeds…for experienced and older riders in particular, the appeal harkens back to their days growing up either on 250cc or 400cc inline 4’s. It is a blast to sound like you’re flying and make a cop still coffee on his lap and you never let off the gas and he catches up and paces you and is absolutely flabbergasted as to what’s happening for a moment
Great video ! Been riding since 2008, and my first SuperSport bike was the 2023 zx6r 🙂And yes, i will agree with you. It does have power hat will scare you lol.
I wished the zx6r had drive by wire, and quick shifter down, so I like to have either this zx6r or go to gsxr 1000r, and have it all!! Lol. Currently I ride the ninja 400, great bike, plenty of fun!!
I'm 57 and just dumb enough to think I'm 27. I'm looking for a track bike and haven't been on the track In almost 30 years. I used to race a gsxr 750 back in the 90s and I kinda miss it. I'm leaning towards the 400 what do you think for an old guy. Thanks and great video
excellent comparison! personally, a 2 stroke NSR was waay more scary and literally jaw clenching than a 600. never actually got that feeling from any 4 cylinder, 4 stroke bikes
Price of the zx4rr is way too ambitious from Kawasaki. It's almost the same price as a yamaha mt09. If you just want a light trackday bike, a used daytona 675 is just as light and has way more power.
Thanks. I'm looking for my first sport bike, ridden dualsports for years. Between the Ninja 400 and ZX-4RR which would you recommend a new sport rider? I could buy a good used Ninja 400 for about half the price of the ZX-4RR, but I love the intoxicating sound of a high revving inline 4. Have the cash for both. Tough decision.
@@dougmaverick3287 ZX-4RR for sure. Everything about the bike is better than the 400 except the price and maybe the seating position. It's not as comfortable as the 400 on longer rides. I have both and if I had to do it again I would have started on the 4RR. It's incredibly smooth and refined and handles like a dream. People complain about the increased weight compared to the 400 but the weight is low on the frame and you don't notice it and the bike just falls into the corners with ease compared to the 400. I haven't flashed it yet and it's still awesome out of the box. You can't go wrong with either really but if you have any experience on motorcyclesI believe you will appreciate the ZX-4RR more. Good Luck!
My ducati panigale and my R6 are lighter and I have 195 hp on the 1199 the zx isnt that light of a bike and has no horsepower so it would be like driving my bike in limp mode
Weird comparison, but interesting. Want the best out of the 3….get the 636. I loved my 636, was the best road sports bike I’ve ever owned, including litre bikes.
My issue with the 4RR, is what people are having to pay for them. Most of them are running 11 to 13k, and that's crazy to pay the price of a ZX6R for the 4RR. Also Kawasaki says that it's 85hp, here in the states they're about 52hp, and the bike is almost as heavy as the ZX6R. The bike is too expensive for what it is. I would much rather have the Ninja 400 over the 4RR. They're like 5300, so you could get one for the street and one for the track for the price of one 4RR.
Great review! Coming from a ninja 400 with a track day under my belt and looking to do quite a few this year. Would you upgrade to this or skip and go straight to zx6r. Ive heard the zx6r is a better value for the money, and there is a low power you could use on it anyway. Any thoughts? Probably be doing 3-4 track days a year for a while. Thanks!
Hello from Wales. I'd like to see a comparison test on track between a ZX6R and a Suzuki GSXR 750, the latter of which is no longer available new over here.
I think most riders are buying the zx-4rr for what it represents as opposed to what it can do. Power mode B on the zx6r and it's the same bike but you'll have A mode in reserve. It's a cool bike for sure but to close in price.
I thought the ZX6R was closer to 127bhp.. has this one been flashed? Either way.. that’s crazy power for just 600cc’s! I’d love to try that 400RR.. memories of the original ZXR400R 👊🏼
Thanks for the review! How is the suspension and brakes of zx4rr compared to ktm rc390? I love the 4 cylinder 400cc engine, just wondering if it immediately needs a lot of modifications. My sister has the rc 390 and it is too soft, with the brakes pretty weak as well.
I havent had a chance to ride an rc390 on track but I would suspenct that the suspension is much better on the zx4rr. The brakes should also be a bit better on the zx4rr with the dual disk front brake compared to the single disc on the Rc.
WRONG! The Ninja 400 makes 45hp and the US Ninja zx 4rr makes around 50. That is NOT 30 more. The 4RR is a ninja 400 with some pretty bells and whistles...
400 is a twin, 4rr is a 4 cylinder. 4rr has double front disks, better suspension, higher rev limit……can’t see those differences as “bells and whistles”.
I have both and these bike couldn't be more different. Everything about the ZX-4RR is better except the price tag. The build quality and performance of the 4RR is in a league of its own.

Honestly it’s the best part of this bike.
@@TysonMoto Less chance of being ticketed and still get to pin the throttle and send the bike to redline. It's so damn fun.
Thats one thing some riders laugh about but I personally find that as a bonus. Going high revs without risking turning into street paste is a plus on my books.
@@Drt0Kkdo 💯
@@KaizoushinI like having the extra speed to get away from trouble too. Like road ragers. Rare but happens. 55 and saw 3. 2 tried involving me
Fantastic video! I'd love to one day pick one of those ZX4-RR's! Seems perfect for the track!

Looking forward to seeing the update Kawasaki will bring to the ZX-6R next month!
I am also excited for the new Zx6r. Hopefully it gets quick downshift, new display.
Nice to see a straight up shootout between all these models by the same rider, on the same track, on the same day.
Properly decat/exhaust, flash the 636, it also does it no justice in stock form. As we all know, Nate can make a ZX6R blazing fast!
Probably a good idea. Needs exhaust first.
the zx4rr is just so badass...really hope other oem's make their versions of a 400cc inline 4
Notice how he doesnt even waste his time arguing?
Pure class
Nice video, one of the best I've seen on the new zx4

Everybody is going to reflash it, dumb to not do it.
Yes this has the reflash. IMO it is an absolute must for this bike.
@@TysonMoto is the re flash from the manufacturer or you have to do it yourself with a third party? I was really considering this bike

Thanks, let’s do a trackday soon!
Anyone know the difference between the Ninja ZX4R and ZX4RR?
I love videos like this! What/where is the track are you riding on?
This is Pacific Raceways in Washington State.
I'm 57 and just dumb enough to think I'm 27. I'm looking for a track bike and haven't been on the track In almost 30 years. I used to race a gsxr 750 back in the 90s and I kinda miss it. I'm leaning towards the 400 what do you think for an old guy. Thanks and great video
If you can find an available zx4rr that would be a great option.
ANOTHER DOPE VIDEO!
Thanks man!
Nice job! For a streetbike, would you lean towards the 4RR for the friendlier ergos, or the 6R for the hp?
I would get a Zx4rr. It’s way more comfortable.
excellent comparison!
personally, a 2 stroke NSR was waay more scary and literally jaw clenching than a 600.
never actually got that feeling from any 4 cylinder, 4 stroke bikes
Which NSR did you own? And yea the NSR is a Turbo Inline 6 and the super sport 600’s are Italian N/A flat plane V8’s …they are about opposites
Price of the zx4rr is way too ambitious from Kawasaki. It's almost the same price as a yamaha mt09. If you just want a light trackday bike, a used daytona 675 is just as light and has way more power.
Hopefully they bring the zx4 single R to the US next year and it’s $8499.
We get it. You dorks in comments think it’s a ninja 400. F$&k off and go get a job.
It's a novelty bike.. Its retro..
isn't it already here@@TysonMoto ?
It is not yet available in US. Only the Zx4RR is available (for now)
Crawling is slower than walking? Which is slower than running? Gee, thanks internet. I always get that wrong.
How much more agile is the ZX-4RR compared with the ZX-6R? Is it quicker around the track?
It feels much more nimble with the smaller profile rear tire. In the right hands, the ZX6R is much faster around the track.
If you're getting 136hp from your 636, I've been ripped off. According to everywhere else i look, I'm only getting around the 120hp mark.
zx4rr lean more beginner friendly due to assistive technology.
The Zx4rr definitely feels safer and more beginner friendly than the Zx6r.
I have a 23 zx6r and it has the same tech aside from the down shift blip. it has abs, traction control and power modes.
I have to say I like the dash on the ninja 400 better than the zx4r. I love analog Tachs
yeah!
Cool !
Thanks!
Is that ninja 400 stock or modified?
It has a Graves slip on exhaust and a 2 Wheel Dyno Works reflash.
Thanks.

The ninja 650 was missing in the lineup guys.
well its not a race or track bike.
Zx-6r has 136hp?????????
Maybe that’s with the ram air added. I think it adds around 10bhp at higher speeds.
Ninja 650 gets no love 😢
kinda the lawnmower option sorry
if youre in the us, i believe the zx4rr is limited to around 54 hp. ecu unlocks the full 70+
it's 80hp in Europe
