Kawasaki's ZX4RR Is The Most Entertaining Sport Bike You Can Buy 

It has positive neutral finder. It's designed to not to go into neutral is you're moving. It may seem odd at first but I think it's great.

Kawasaki keeps the real 4cyl engine culture in contrast with other companies that turning bikes into 2 cyl ❤💪💪

I think the reason it's hard to find neutral is that Kawasaki may still be using the "positive neutral finder" feature that I had on my old ZX6R. If you're stopped in 1st gear then no matter how hard you pull up on the gear shift lever, it wont go past neutral and into 2nd. The downside is that it's very difficult to slip into neutral while you're coming to a stop.

Honestly as for me I think this is my dream bike. Ive ridden 600 before but theyve got too much power imo. I just really like everything about the zx4rr. the 4cyl, the comfy-agressive ergonomics, the looks, the suspension etc i cant stop listing great things about this bike! Unfortunately i’ll have to wait 2 years to get it since i have the restricted european license…

Having had my Bandit 400 for a very long time, I can attest to the appeal of this type of bike. Same as with my VTR250 Interceptor, they are frantic, tossable little toys that sing their best song when you are riding them in ways that would be abusive or very illegal on other bikes. Unless you are smaller or really tolerant of compromises, they are best as a second or third bike, or a track toy. Life constantly above 10K rpm is only fun in short bursts and it ups the maintenance schedule greatly, especially on older bikes.

To me it's just not worth the money. Just too close in price to the 600. Personally I buy used older bikes that are just as good if not better.

I bought the first Ninja 400 my local dealer got in stock on the first release a couple years ago. Kawasaki was doing the same event that day and I fell in with the pack right after the paperwork was done. I had a blast on the 400 and didn’t feel restricted by a bigger bike’s need for open road

This is a really nice bike but I think it's an 8000 dollar bike as it sits. If they brought it with the full 80 HP then I'd be down for the current MSRP.

Gotta give it to Kawi they are the only ones making the bikes nobody else wants to make, small 4 cylinders that rev to the moon and keeping the 600 class alive

I think Kawasakis have a thing that keeps you from going to neutral while moving. Helps with the 1-2 shifts.

Bro you seemed a good experienced knowledge about MOTORCYCLES ... !!!! Can you give us some RIVALS of this ZX 4RR .. ??? ( On the based on it's performances ). Ans :

Kawasaki should have priced it much closer to the ninja 400 if they wanted people to buy this bike. As it is, people will see the price of this and just get the 6r instead. They're definitely not getting cross-shoppers of the 400 or 6r at this price.

There is no throttle slack because it is true ride by wire.

Honestly this bike seems perfectly okay stock for our roads in the Northeast, after a tune and exhaust i can't see it being useless. I just would need something bigger as well for the hooligan in me

the ONLY factor would be, is it restricted? If so, it's just soso.. If it's un restricted and tuned, it's a good time.

Quick shifter is “trash when you are lugging a bike around that’s made to rev High. You have a Tach for a reason. 😂 use it. It doesn’t count as high as it does for ascetics . Just a little public service announcement for folks. (Not Hero RR) my main guy here! Rockin channel. But anyways, anyone who rides ima high rev supersport bike and rides around lugging it in around 2-4k RPM’s well your doing much more harm then good to the engine. Truly. It puts in needed stress on pistons valves , cylinders etc etc. it’s made to rev high. And thus it’s less stressful on the engine at higher revs. Believe it or not. That’s 1000% the TRUTH . Anyways thanks for upload .

This was made for twisties and to destroy the 1000s on the track.

We went to this in our area last year. Day 2 of the event some lady crossed lanes in a car and took out several of the riders, nearly killing the lead Kawasaki event guy. It was apparently a mess. Doubt the will come back for a while.

mine is tuned by 2wheeldyno works and its insane, sounds like a 1000 aswell

The induction sound on that thing is sweet. Obviously I think the power should be a bit more "unlocked" at that price point, but needless to say I think it could be a weapon on the track with the light weight and decent level of tech.

Love all your videos, my 954rr which I bought was from watching your videos, but I can tell the 400rr is way underpowered to me

For a few weeks… until you need more power.

Name any sport bike that does not need a full exhaust and tune from the factory? Unless there is some track series that this competes in, i do not see the market on the street.

I'm in love with the concept with this motorcycle but I don't think I'll ever pick one up unless it's in the used market after a few years. I own a brand new 2021 ZX6R and I was craving having a lighter small CC bike and ended up buying a Ninja 400 a year and a half ago. Honestly, I'd rather suggest someone doing the Ninja 400 and ZX-6R combo vs buying a ZX-4R. It's definitely a niche motorcycle and I was actually super excited for it at first but it's just not for me. I feel like being able to choose between a more powerful, aggressive ZX-6R or a more comfortable, lightweight Ninja 400 at any given moment would be the better option if money isn't an issue. Now if I didn't already own a ZX-6R, I could totally see myself just getting a ZX-4R but I'd probably still eyeball the regular ninja 400 a bit as well. Honestly it really comes down to preference and what you're going to use the bike for. I mostly use my 400 for commuting but the thing still rips when I want to have some fun on it in the corners as well. I do want to see a true ZX-4R (unrestricted) vs a race 400 to see how they fair against each other on a track day.

kinda sounds like my weedwhacker lol. Man, I'd love to have one. Looks like it'd really be fun to just wring out in the twisties.

These are neat bikes for sure i like the sound

It always amazes me that guys like your friend turn up to test ride bikes in zero protective gear other than gloves -

im not deep pocket, a 400cc with 250 maintenance already good enough for me ❤

These all need to be de restricted, they're 50HP factory and well over 70 de restricted. You can hit 80+ with mods.

The guy wearing jeans, sneakers and a hoodie hates rain? I'm surprised....

I have a ZX4RR. Hit me up if you have any questions, I have quite a few miles on mine.

Hero!! I love your content! I'd really love to see a video on 600cc naked bikes if you would be interested :) I have a Benelli Tornado 600, which is basically a more pasta'd out 599 hornet. I'd live to hear your thoughts on the segment and whether a naked 4cyl middleweight makes any sense.

Personally would get an Aprilia RS660 over this. More bike for not a lot more money.

3:51 subtitles say, “you gotta rub it out dude”

$10,000 for 52hp on a sports bike??? No way on earth.

It's a great looking bike, but giving the example of my country (Portugal), you have a Kawasaki wih 400 cc with 77 hp, costing €10300, and you have a Honda CBR 650r, wih 650 cc and 95 hp consting €9900... guess what the majority of people will choose!

I want you to see how it feels after yhe tune. Your gaining 20 hp. Plus the power wont be cug

The only time it's cool and fun to hate on your mate's bike =D

Beavis n butthead

even without the exhaust, euro tune is about 75hp

my only problem is it is almost the same size and price as a zx6r

Awesome man, I really like your content. I got few questions: 1. How much vibrations are there on this one compared to 600cc's other performance bikes? 2. sound is little thinner than 600 it seems, is that so? 3. Suppose If I got 4R and 6R to choose from then which one would feel better in terms of refinement and overall? I am leaning towards new 6R. Final one: I like high revving smooth motor inline sound, so which one would be best pick if i get the option. Example: Daytona 675R, 2019 6R etc.

any thoughts on using this for a daily 50 mile round trip to work ? (all street)

you dont need to clutch my guy... it has up and down quickshift with auto blip...

Yeah y'all getting passed by way too many Grand mother's and papa's

Now they just got to embrace older styling and not make them look like crumpled tin cans or a freeze frame from Michael Bays Transformers.

Si vas a ir lento mejor ponte a caminar

Hey HeroRR, i was recently in a little crash with my 954, f150 blows past his stop sign and doesnt see me, anyway my bike only really has front-end damage and I want to fix it up, is there anyway you give me some guidance? I can send you pictures and ill keep my questions short lmao. This is my first time working on a bike and I would love some help from you!

My dream bike. I had Kawasaki ninja zxr 400, it was my first big bike. It was mine for 8 years, I was happy with that bike, but was old 1992. Then I changed for Suzuki gsx-r 600.

Brooo i knew i recognized those streets, i moved out to westborough but lived in hyannis/dennis for 3 years

That bike is tuned down to 41hp. They can be tuned up to 91hp.

Many years back i had a Z400j. Did some tweaks and had a good linear powered bike. Never ridden a modern 400.

Bought my 2014 zx10r from pilgrim powersports

You should try a ZX14r pretty entertaining

Kinda like a old cb1 400 super four

Why did you delete your Facebook Danny?

I got a 300 in Massachusetts

I've ridden many Kawasaki sport bikes but I haven't had an opportunity to ride the new 400, a lightweight high revving bike has got to be fun to hit the back roads with.

Thanks for this video! Have you tried out the 2024 ZX-6R yet? Can you do a video comparing it with this ZX-4RR? I went from a 2020 Ninja 400 (which I loved as my first bike) and then after 3 years I went to a 2017 Ninja 650. I like the 650 because of the power, but I do miss my 400 😭. Trying to decide if I wanna switch to either the ZX-4RR or ZX-6R. Help! Lol

Give me a ZRX 400, and I'm in.

It would probably cost you $3000 to delete all the emissions stuff on that motorcycle

The pick up like 20 horsepower on the top end when you de restrict them

Demo on the highway. Yay...

So sweet. Too bad I'm poor

$10,000? that would be a firm no for me. There are lots of other better bigger cc bikes out there for much less.

In your opinion what's the bike with the best exhaust sound (600cc) ?

they just had a recall too

Isn’t this bike meant to be drivin above 12k

Flash it

Good review.

Oh shit my dude

Love your videos & insights but that outro music is...cancerously unfitting.

no biker likes rain. 😂😂😂😂😂 it sucks ride under rain.

For 10K??? Uh..........YEAH,that's WAAAAAAAAAAAAAY overpriced for a 400cc sportbike! I remember when I first purchased my 2000 (almost 25 years ago) Honda CBR929RR,THAT was 10K and WORTH EVERY SINGLE PENNY TOO,as it had PHENOMENAL POWER in "stock" condition! Of course,I added an upgraded exhaust to it (Just the can,as the REST OF IT was all Titanium!!!) and uploaded a much better fuel-mapping into the ECU,and from then on........OH YEAH,she was a sweet machine!!! Not that she wasn't beforehand (as the price for it new,was justified!) but PAYING the same price for a 400cc bike today,that has "meh" stock power to it? I'd pass.........although I'd LOVE to swing a leg over one with an upgraded exhaust and has been flashed!!! Hope you find one and post about it on here! Good Video Man! : >)

I dont see how one can say a ninia 400 gets boring - it's hella fun and punches way aboves its weight especially in the twisties. Best bike I ever sold

Underpowered and way overpriced. I was behind the 2023 ZX-6R during the Kawi Good Times Demo the other day. After a 2nd gear easy right turn onto Jackson School Rd from Evergreen, the 6R effortlessly pulled away from me while I gave the 4R all its beans. After the ride, the 6R guy told me that he only revved to 7k! Even merging with freeway traffic I had to keep the 4R engine wound out and in a low gear. I found myself constantly shaking my head in disappointment during the ride. Even when you’re stopped, the neutral notch is super small, so you lose focus on what’s going on around you while your going up and down trying to get the trans to hit neutral. All this for $13,000 out the door.🙄

Reminds me of my CB-1

title is a lie lol. slow ahh bike lmao and sooo expensive to get passed. next.

only a novice rider with no talent would try to find neutral before they have stopped, stop the bike and then find neutral, it's not hard for those that can ride properly.
