2023 Kawasaki Ninja ZX-4RR Top Speed Test 

Why would you switch camera angles to the exhaust on a top speed run? We want to see the speedo climb. Zack short shifting to is saddening on a bike that revs to 16k.

@@kluthage421 Thats because the power was rolling over. You can hear it get less interested up top so there was probably more acceleration to be had by shifting early. Blame it being restricted because thats the only reason.

Can you get it a flash and get it back to try again please? I feel like when people are buying this most are going to be doing a flash as a first thing and probably an exhaust aswell - though how much difference that makes is probably minimal. It would be good to see what it can do in the spec most people will use it.

Would be interesting to see how fast the paralel twin ninja goes :)

Guys... Is the KOVE 450RR going to be sold in your country? it would be nice to hear your review about that interesting little four cilinder!

This bike is anything but overpriced, try to build the same bike yourself and let me know how much you spent

Yup, and I'm buying one!!

​@@Carlisho such a stupid thing to say, ignoring realistic and genuine criticism just because they can't also build the same thing is the downfall of any company

@@BooStairs im not ignoring criticism, the zx4rr is genuienly a good value for the price, if you want to put the same components the zx4 has on your ninja 400, the money not only quickly reaches the price of the zx, but it goes over it by a couple of grands… and that is still not taking into account the engine, which you are still down 2 cylinders, down a couple dozen HP and down half the revs.

@@Carlisho same price as a zx-6r and they couldn’t even include an aluminum frame? there’s a lot wrong with the price vs what’s actually on the bike

Thanks 🙏

Oh shit that's what I was wondering how can my 400cc street bike be faster than a similar capacity RR 😂😂 it's mph ffs 🤣

Thanks my guy

My momma said Metric are of da devil 😈 - waterboy 😂

Ah okk zi

Use a separate audio recorder with the mic under the seat to eliminate wind noise and record all the music.

How do you notice the intake noise?

City is the last place for this bike…

This is a street legal motogp bike, not a city bike 😂 you can rev it up in first and second gear yes. But this is not for city riding

@@James27Simko Bro, thats a 70hp beginners bike :D

@@KapitanPisoar1 I know? When did I say otherwise? I was saying to this other guy that the bike is not designed to be a city bike 😂😂😂😂

@@James27Simko Well you called it "street legal motogp bike"....

Same 😅

You came?

@@toddstephenson7154🌚

Don’t forget the CBR650R!

its called zx25r. 18k rpm

@@PokeyCottons what is better cbr or ninja?

@@rjsthgsaargagra are you asking specifically about the Ninja ZX4RR vs CBR650R? Basically, the CBR650R is better for the street and the ZX4RR is better for the track.

@@hilmiyahya3027 Video of track dressedzx400rr>>> We ride the $26,000 Graves Motorsports Kawasaki ZX-4RR! - Cycle News

My 2013 ninja300 used to do 0-60 in 4.8 seconds, id have expected this to be faster than 0-60 in about 4.2, maybe its rider error but I was hoping for more

The Parallel twin offers more low end, that's why it has a good 0-60. The ninja 400 is an awesome bike as well. This is just nitch ( don't get me wrong, I ordered one hehe )

@@James27Simko watch this video>>> We ride the $26,000 Graves Motorsports Kawasaki ZX-4RR! - Cycle News

5 seconds is horrible.

It sucked

💯

Lol. More than double. 😂

😂😆😂

They need to be careful since they are part of an organization that sells motorcycle parts. EPA published a guide for fines to be given to any company that impairs or removes emission control devices on certified vehicles or sells equipment to do so. In 2016, Harley Davidson got fined $12 million, so it is no idle threat. In 2020, EPA dropped the individual fine to $1,000 (from $4,819), and some think that this means they are likely to start going after more individuals.

@@jfess1911they went after dynojet too the power commander 6 is a waste of money now

@TM-ot3vl I read one of the enforcement documents and it stated something along the lines that there is no problem if the emissions still meet the standard. This is why some aftermarket exhaust systems that include catalytic converters are approved, even though they are louder. It is possible that a new map that eliminates the flat spot but still meets air emissions standards would be acceptable, even if it is louder. I would not like to be the test case, though.

@@jfess1911 the new PC6 only allows 15+/- adjustment vs 250+/- like it did before. The only way to make an exhaust louder like ford did was to make a valved exhaust system where it by passes the muffler. Other than that you’re SOL. Tuning motorcycles used to be easy now i have to send my ecu in to some place in the states to do it which is annoying. If they care about emissions so much why not just switch to hydrogen gas which has a 80% reduction in emissions while keeping gasoline vehicles…

@TM-ot3vl I am afraid that I am a little dense. Would you please explain the 15+/- vs 250? I have never played with an ecu.

nah the US version is heavily restricted if you try the asean one it as fast as 600cc from 30 years ago

0 to voided warranty in a flash!

@@aluisious They don't void your warranty lmfao

I saw a before and after video following a remap, the bike accelerated much quicker but I think the top speed remained the same at 132mph.

He already did the ecu flash tho

@@16driver16 no this is a stock bike review, as always.

Suzuki laughs

Also Kawasaki: “Here’s another bike with a 650 parallel twin”

Yamaha is laughing at this and pointing to the Lexus LFA,CP4 R1 and R6

@@azurecoast45 i dont get that, manufacturers hate to spend money and make no sales yet stick that horrendous 650 in 3 bikes? do they hate themselves?

its because every motorcycle has straight cut gears 😂

Thank regulations

Youre right its not about price, until you get a way better bike for the same price 😂

Maybe someone has a different opinion of what makes a bike way better (was my point).

La CBR 250 es otra joya que recuerda a los años 90,No corren como una 600 pero por peso y sonido son pura adrenalina

@@wanderer397 it comes stock with an extra 20hp outside of the US

@@Tihihihi007 what and who has vfr 400 talking zx400rr four ?????? What the fugg ate you talking about?

People don't upgrade 400s for top speed lol.

@@superduperkid3143 people who race them do

When was 130 slow? That speed will kill you in a caged car.

Means you werent born in the late 80s or early 90s. They were so many 4 cylinders 400cc from all the major Japanese manufacturers....we were basically spoilt for choice. I myself rode the cbr and rvf and my preferred choice was the cbr with Yoshi pipe.

oh boy, do NOT look up the specs for a 30 year old NC30.

It's 80 hp...

@@clementroyc The version released in the US is restricted. And I'm pretty sure that bike is completely stock.

@@Jaslath oof! That's very restricted unfortunately. Wouldn't think I'd see us spec vehicles so down on power since the 80s. But fortunately though, I don't think many people are letting this one of a kind, nowadays at least, stay so below it's actual potential

@@johnybenx3165 I agree. I doubt many of them will stay stock for long. Let be honest here, outside of the track what use does someone really have for this thing? It's only $1600 less than a ZX-6R.

It *IS* going slow.

Didn't he already do that? Also there's only about 1k rpm left on the table idk if he could get more than 10mph extra out of it with any amount of hp

@@16driver16the power curve goes flat after 11,500 I have seen videos where they were going down a free way and got close to 150 mph but it has to have opened up ecu

Get the ecu unlock and it can go to 140-150

​@@occlusion6557you can't go that fast on it. Even my 6r only does 150-152 mph top speed. I think it can do 160 with sprocket change, but that's fast enough for roads.

200 kmh effettivi in Europa ( Italy) con 80 CV in America è limitata con CV in meno 😢

Yo crossplane 400cc yamaha would be nuts, some competition form the other manufacturers

You'd basically get the same top speed, you'd just reach it a little faster. F=MA. Acceleration is related to torque and mass. Top speed is related to horsepower and aerodynamics.

@@valensinclair6750I kinda get the physics equation, but how would you explain this on a grom when weight is such a determining factor on top speed

Everything counts in top speed and believe it or not rider skill. The surface, wind speed and direction, density of altitude, gearing, shift points, throttle body closure, bike and rider aerodynamics, etc etc. I think this was the best top speed for this no matter the distance and rider weight. Fix the throttle body closing in sixth gear then it could pull some more gearing then the riders weight might make some difference given the short running distance. We once did an experiment at the Bonneville Salt Flats with three different size riders on two different bikes running the same distance (3 miles) with no changes to the motorcycles. Rider 1 weight 155 pounds, Rider 2 weight 180 pounds and Rider 3 320 pounds. Rider 1 was faster than Rider 2 and 2 was faster than Rider 3. On bike 1 rider 1 was 20 mph faster than rider 3, and on bike 2 rider 1 was 25 mph faster than rider 3. The aerodynamics of a 155 pound rider compared to a 320 pound rider was huge as you might expect. However, in the run the bike was clearly maxed out.

​@@GotPoopWeScoopI can only think of tyre deformation under load as the tyre drag is a major drag for vehicles, such as aerodynamic drag above 160km/h

​@@valensinclair6750agree to disagree. Yes the rider weighing less would reach the top speed quicker due to less weight but a rider weighing almost 50 lbs less would absolutely carry more mph.

Rider weight affects acceleration pretty strongly, but has little affect on top speed assuming the track is long enough. Now being fat with large frontal area is a different story…

Whoa! That's cool!

He prolly didnt tune it and ECU flash it, if he did that plus changing the exhaust with a full system it could prolly hit around 165mph or more

Cut the crap with your dinosaur vfr400!!😅

I totally agree, I had a kr1-s 250 did 140 all the time
