Almost 80hp in a 400cc is almost unreal , remember a 390 makes 43 hp ninja 400 makes 45 making 75 hp on a 400 cc is crazy and weight too , thats goona be a spicy boi to ride
Remember that's AT THE WHEEL. Crank HP has got to be damn near an older 600cc!
Finally someone who gets it
â@@AjackLee4bet my 600 would still smoke it
@@jonog5632 no shit.
And a zx14 would smoke your 600
Weâre stating obvious facts, right?
@@AjackLee4 I have a bruise from all the at the RW assumptions that everyone appears to make
50% HP is great no doubt. But lets be honest, looking at the before dyne chart, clearly it's just uncokblocking the USA EPA noise restrictions that seem to be put on every new USA bike nowadays. Not sure Kawasaki ever intended to release this bike with that flat nothing above 11500 rpm. Doubt it's being released the same way in other countries. Definitely a must do for anyone that buys this bike though. Nice job 2WDW
well said
Exactly, the factory engineers know how to make the same amount of power. It is restricted for noise regulations and emissions, with the understanding that most owners will tune it and unlock the power.
You know its actually euro5 standards. Not us EPA standards. Euro5 is what serves a huge portion of the motorcycle market and drives all the movement to low revving 2 cyclinder and three cyclinder bikes from high revving inline 4s.
@@absolutelysobeast Yes euro 5 is a thing, but USA has extra de-tuned versions (more than europe and other countries) because of their own special USA laws
it is released unlock to our country ( Philippines ) I got mine stock from factory 80hp -/+
50% is MASSIVE!
That's what she said...
cant wait to see the effects with a FULL exhaust and velocity stacks
Whatâs a velocity stack?
â@N/a they are aftermarket air intake stacks that are wider. Allows more air into the motor. And with proper fuel mapping. More power baby!
It's a set of cams away from making 100 hp
Velocity stacks move the power band does not increase it, since it changes the speed of the air flux
â@@Deadslayer12 not wider, it can't be since the throttle body has a specific size, they are taller or shorter, and it only moves the power band, make the air flow faster or slower on certain RPM
This is awesome. 50% đđ€Ł thatâs bonkers to even hear. If I get one, the ECU is absolutely gojng to you guys. Nice work!
The bonkers part is Kawasaki would have originally designed the bike with the full power, and US EPA noise restriction laws cause it to be neutered.
@@IN_ZANE_ Was it EPA? My dealer I bought mine from said it was CARB.
@@djmohab2 IDK for sure exactly all of the various restrictions at play. I do know that (not inc. Cali) USA is not as strict about environment emissions as many other countries but does have some weird noise limit restrictions in place that are more strict than other countries. Either way it's restricted and needs unlocking.
@thomasb282 no, because Europe gets the bike unrestricted
@@thomasb282 Nothing to do with euro 5, it only happens in the US, everywhere else in the world gets full power straight from the factory
We would only get about 5 hp more in our country as we don't get a neutered bike.
But for you guys that's huge gains!
Pity you have to go and spend money above the purchase of the bike to get the stock HP out of it.
Thank you! It sounds great on paper only because they are ripping us off upon purchase.
â@@Petchyalater exactly
American Capitalism at its finest...
You donât need to spend anything more than the flash, that puts us on even footing. Thatâs hardly a big deal all things considered. Less than ideal but not going to put me off. The slip on is far more expensive obviously and not needed for 4-5hp
@@Team_Nacho_Moto thatâs quite the ignorant comment. It literally is demonstrably false/inaccurate. What youâre suggesting is that its being sold in a locked state so that money can be made again on the back end to unlock jt. What youâre failing to comprehend is that only makes sense if Kawasaki was the one choosing to lock it, and if kawasaki was making the money to unlock it, which they arenât. So thereâs nothing remotely stereotypically American or Capitalistic about this. Quite the opposite.
There is nothing American/Free Market Capitalism about Govt. Mandates crippling a product, paying to get around said mandates is quite American though Iâll give you that
In reality free market capitalism punishes such behavior. If there was a competitor to this bike that didnât need this additional investment then all else being equal the market would punish kawi and sales would suffer.
In this case though, thereâs no free market economics to be seen
Remember, in 1987, CBR600F was making 84,3 HP at the crank. Evolution is damn impressive.
now 600 140hp
Idk itâs to be expected, the 400cc sports bikes on carbs in the 90âs did 60bhp, and your 600cc bikes did 100hp. Now with EFI what 600cc does 120hp ish and 400cc will do 80hp. Seems about right to be honest!
True, but it'll take a turbo on the 400RR to make the Hurricane's 44 lb./ft of torque, which is what moves a bike off the line. Not taking anything away from this little bugger, though. It is downright impressive.
ââ@@500erider I bet I could get that bike off the line with a lot of revs & a lot of clutch just fine. Torque doesn't matter off the line you just gotta learn how to launch bro it's basic rider skills.
USA ZX4RR came detuned to 50hp, then retuned to it's stock power 75hp again. Nice
Doesn't matter if you can restore it to full power. An out the door of 12,000 dollars makes it not worth it.
ZX4RR 53whp $11.5k OTD
Parts to unleash for 73whp $1k
Total $12.5k
ZX6R $12k OTD @ 119whp stock
Edit: The comments had shine some light âšïž so I'll be getting one!
Yea, but I don't want the extra horsepower that the ZX6R has.
It's almost like you're missing the point of the bike. Same thing as how muscle heads cannot grasp why people would want a 4 banger that revs to 9k instead of their 500hp v8.
Don't forget VOID WARRANTY. PRICELESS.
@urgandma I completely understand what you mean because 20 years ago I had an s2000 that revs to 9k which was super fun because of how nimble it is. My issues with this bike is that it's not just the price but it's weight is also close to the zx6r as well and the zx6r is built in Japan while the zx4rr is built in Thailand to cut cost. If they can cut cost like that then they should market this bike closer to $8k instead of $10k.
@@quanwick4516 and that is a valid complaint, but everything comes at a cost. It would amazing if they could've made it a super light weight frame with better suspension, but that would've made it cost even more, it's a whole new engine after all. Lots of RnD was spent on this, and it's low volume, so cost has to add up somewhere. Regardless, this satisfies that desire that people were looking for. High revving, high performance small bike that will allow you to use all of it on the street or track.
No. The bike was neutered. You don't gain 50% more power. It was made for that power already. There's no gain here. More like an unlock. Bad State Laws! Still getting one...but bad State Laws!!!
Bad U.S State laws, nothing to do with Kawasaki mate.
It definitely does if you buy a US model.
@@2wheeldynoworks + Canada
@@hoanmac thereâs many vehicles that ship physically neutered like the USA version of the e36 m3 100hp down and with a totally different motor.
Countless other examples too. Those owners had to spend $10k on forced Induction JUST to get to stock power output on the euro model. They still considered it a gain, because it is a gain. Call it an unlock if you like, reality is it is ABLE TO BE UNLOCKED, and easily, and kawi should be praised for that, they couldâve not given it to us at all, or decided to make it impossible to unlock like bmw bikes of late to protect the company from governments. It goes both ways, all that matters to me is we have access to the bike and a way to make it whole.
@@Fee.1 Every manufacturer has to sell into a market with regulations. They have to sell a replacement for the 600's that are now effectively dead due to regulations. Has nothing to do with a manufacturer being kind and giving it to us at all. I'm sure they've done their due diligence in surveying the market and consumers well before taking this risk. Go ahead and take it back and sell nothing. I'll buy what I can get or hold off and wait for Honda or Yamaha to maybe release their inline 4's. Doesn't matter as there are options and I am reconsidering a slight bit here if a 600 or 750 super-sport makes more sense while it's still available. They effectively brought to market a bike that drives my spending decision their way. The 4's are pretty special and glad they made one as my love is with an FZR-400R. Kawasaki took a risk with development and good on them. It's to tap into a market and rebuild sport bike love and be within regulations. Yes they've done good there. I would've bought a ZX-25R had it been available and then regret it because it's too small. Who doesn't want a power rocket in a small package? We all know with 400 racing it's popular with the Ninja 400's as the bike of choice. This takes the sport to a whole new level. We're all just not happy consumers on this side get the neutered end of the stick. Will it stop us? No. We all know bikers are crazy and will do anything to UNLOCK 50% more power. Win, win, win for the market and after market.
I've owned liter bikes, but a baby inline 4 SuperSport is all I'll ever need to be satisfied on the street.
I bought a 22 zx10r Iâm realizing it was dumb to buy a street legal racing machine that I would never use all of it full potential on the street I really should have waited and bought something like this.
Wait till you ride it đđ youâll change your mind.
@@Lyretharnothing wrong with that. Full potential doesnât last at full potential very long. You donât build a 600 hp motor and run it at 600 on street. You throw it down to 485-500. Why because. You want longevity out of your 600hp capable motor.
Your never in perfect environment. So your fuel might be off. Temps might be off and humid. And your spark could be suffering from humidity. All those things are a factor honestly. Iâm happy I have a 16k redline. Doesnât mean I use it all the time. And nothing wrong with that either. I see a lot of these 400âs having issues within the year cause folks redlining them to get moving fast where a 600 or liter would be at 10-13k. Rpm creates heat sorry. The idea is making power with out heat. Not with it.
@@alejandrotobienne8220Nah. Youâre talking to a guy who sold an 1199 S, bought a WR250R* the next day and had the time of his life lol.
@@Lyrethar how much you want for it
Don't hold out - what full systems do you have coming ?
The Graves slip-on is tempting, but a near 10 pound weight loss (Akrapovic) with a full system is more so.
I've had my 4RR for a week now, and no matter what the critics say, it's worth it.
Do you feel itâs opened more since owning? I keep hearing this one especially needs some riding before it shows itâs real strength.
@@Percalated ..likely it is still within the running in period/bracket of 'occasionally spirited usage'
People underestimate this bike just because they don't understand how neutered it is out of the factory.. i love kawasaki for don't giving up on four cylinder. Such a cool "little" bike, reminds me of that art piece that is the cbr400rr
Imagine once that catalytic convertor is gone. Bet we see over 80whp
So glad Iâm being recommended your vids. When I first started riding my R3 I made modifications without ever making changes to the ecu. Now that Iâm looking to buy this bike⊠Iâm guaranteed going to get your ecu flash. Good stuff man
Rumor was that the ZX400RR in the U.S. was going to make 52hp. I guess that is not a rumor.
Thank da Feds!
Yep super lame.
if i was a smaller guy this would be irresistable,remember all them crazy 400cc 4 cyls the japanese market got in the 90's? The ones we all drooled after? Well, here they are again!
Cant wait for full exhaust video
That will be an interesting data point. Given how seemingly consistent Kawi is at choking the headers down, there could be another 3-6hp hiding in there.
Look at what Brock was able to do with the Z900 because of the small diameter of the factory headers. Thank you so much Eruro 5!
Itâs insane that USACanada made Kawasaki dull these bikes by so much! Itâs offensive that customers have to pay (huge respect to you guys btw for saving this bike) MORE money to have an ECU flash to unlock the bikeâs potential.
I think the most telling part of your map is the torque it now makes heading out towards Redline.....that improved significantly
I really foresee an interest in 500-550cc sportbikes in the near future. This category was all the rage in the early to mid 80's and with todays tech could make for an exciting ride once again.
400 80hp and sounds better than any other bike today. Small flickable, mmmmmmmm me like
Data is never irrelevant!!! Youâre doing a public service with each run lol. Each run in each variation will be of massive help to some rider & his tuner somewhere, guaranteed.
i notice the Yam R7 makes 76hp stock with most journalists fawning all over Yamaha Reps - this is a proper sports bike and is a bargain, thanks for showing
Itâs just crazy that emission laws are strangling that bike that much.
Good luck with the warranty.
Love your no BS style ! - makes a refreshing change..so I've subscribed đ
Every time I see a bike in the U.S get tuned they always pick up insane gains... you guys must get bikes that are restricted for the U.S market?
California bullshit emissions
The real aspect is not so much the increase in torque and horsepower but the fact it makes those improvements across basically the whole Rev range that means a massive increase in response and acceleration without going beyond the 4 HP gains initially those are good enough for most people
ZX4-RR is listed, stock, @ 75HP in the UK.
Massive power in a 400cc that's been designed to meet emission regs while Honda is withdrawing their on JDM CB400.
So it makes the power it should have made when it left the factory, but i assume now with the flashed ecu the warranty is void?
Nah
@@Fee.1đđ very much yes. What you nah about. And yes they can tell if itâs been flashed even if you put stock mapping back on.
@@alejandrotobienne8220 youâre confused
It's now making the factory rated CRANK horsepower at the WHEEL. That's wild.
In europe it is going to make a lot more than 50 hp. More like 75 if I remember correctly. For some reason you US guys get the toned down version of the bike.
Would love to see some short velocity stacks pushing power later in the rev range
Isnât this almost entirely because the US model is basically factory detuned? Now it essentially makes 2/3 the HP of a stock 600, with 2/3 the displacement.
I am REALLY curious what it feels like to ride one stock vs your 73hp version. I canât fathom buying a 400 for 600 money though so I doubt itâs in my future.
Correct, even the EU version will have 77 hp stock.
My apologies, I missed the part where you said you tuned the stock system for the first dyno run.
This bikes built to rev and be racey but be "slow", not fast. Look at the curve, good mid range so its not gutless, cruising, but tapers to let you rev it. Slow bike fast. Its expensive bc its an experiment and really niche.
Contradictory, but pretty easy to understand. I like what they did.
Anyway, cool vid. The Graves can looks delicious on there!
That's a savory looking bike.
mmmmmm spicy
Just wish it had other colors
@@budharvey5873 wait Iâm confused is it too busy or you love it
@Fee too busy. I'm sure many love it though.
@@budharvey5873 why did you say you love the latest krt colors then? What am I misunderstanding
What a cool bike. Wouldn't be practical unless you're going to track day/race it. I would imagine dealers are going to be asking considerably more than msrp. Is it worth basically more than a new 636? It will probably be more than a new 636 when you add in exorbitant probable mark-up. I'll take the 636. Great stuff as always Nateđ
In America, "practical" is not a consideration for a motorcycle. Motorcycles are nothing more than toys for Americans.
â@@spartanx169x this!
Loving it!
The 636 is apparently getting a major update for 2024 too fwiw
â@@spartanx169xthen I must be the exception to the rule because my 636 is my only form of transportation. And if it's your daily you can't treat it as a toy or at least I don't
Couldnât fix that dip at 10k?
I doubt seriously you will feel it when you are keeping this engine zinging through the gears in the mountains or on the track ! Lol
In the uk we get full power no restrictions like in the USA
Do keep in mind that if you live in a state (California) that req motorcycle emissions inspection testing you need get a 2nd ECU and swap it same with any other parts and the exhaust system back to stock, Also note you automatically void your warranty with flash ECU.
You could just upload stock map. No need for two. Warranty claim yes. But thatâs near impossible
@@alejandrotobienne8220 yes you could do and need lean how to do reprogramming and you need all the tools to do it plus reg computer
Motorcycles are exempt from being smog tested.
No, the state of California does not require smog testing on motorcycles.
@@robertmeyer6867 don't get caught by the police if do and a see an aftermarket exhaust pipe you will get a ticket and yes you get pass smog
What would be the figure if Air filter + Exhaust without ECU flash? I believe this combination is common for most rider.
It won't help much w/o flash
The ECU is the real restriction thanks to US EPA noise regulations.
I reflash my 2022 CB500X and it goes from 39.6hp at wheel to 50.2hp at the wheel with only Moriwaki slip on
I think theres a version of the ZX-4RR that is "unrestricted" and outputs 80 hp, somewhere in Australia
As far as I know its basically unrestricted anywhere else except in the USA. Even in the EU it will be released with 77hp.
When someone asks me why I risk my life for a little adrenaline. âItâs FUC*IN COOLâ
This bike is meant to do this power figure out of the box. You just unlocked the USA specific ECU block.
Cute bike ....Now, about that new Ninja ZX-7RR đ€
Waiting for the results of a full system, especially since I mounted up a full Akrapovic yesterday.
02:23 - Stock
02:41 - Tuned
Solid numbers but keep in mind 250cc inline 4 bikes a few decades ago were making in the 40s.
So put a tiny 25-shot of Spray on it would bump the gain up to 100% đđ
70+ HP on a 400cc is amazing. The best part is, insurance here plates this bike like a small dual sport. The difference between this bike and even a naked 800cc it's about 1500/year.
In Europe this bike has 80Hp from dealership
What is production expected to be this year? And will it be increased next year? I hadnât heard anything about limited production yet
If they sell they will make more. They have to sell and pretty sure they will
What we has not notice why the 400 lost power is the exhaust header that has the same size as the ZX25R
Quick question @2wheeldynoworks would the smog block off plates offered by graves, make any gains, with the slip on, air filter,& your tuning?
Flashing Ecu, Does it harmful for the engine longevity??
Definitely not. There are many things adjusted in the ECU. Fuel and Timing being the main obviously, if its throttle by wire almost all factory bikes close off the throttle substantially in the top end and not including the on off switch feeling being fixed. Nate definitely knows what he is doing over there. Im on my 3rd bike flashed/tuned by them, most recently my super duke r last week. Essentially your bike makes more power but also running more efficiently within safe parameters.
How much of that is just the ecu flash? From 53 hp to 70, sounds like the ecu is where to put the $ first. Thanks for making this clear where to go first. That alone makes these a very tasty proposition. To the track yall!
ZX4RR (ASIA Version) goes brrrr with just ecu flashđą
This bike is supposed to be 75hp stock. We got shafted in NA.
Its not like 50% gain, the kawasaki claim in stock is 71-75hp, but just because the US restriction, itâs only produce around 50hp, i saw on the other channel, the factory sets the throttle only open for 50% when it reach 13/14k rpm, so with flash ecu and set the throttle back to 100% at 13/14k, the bike reach back to around 70+hp like the factory claim, i believe this bike can go over 80hp with tune & more mods in the near future, which is amazing, btw i have the zx25rr here in Indonesia, same features and bike, just smaller engine with 250cc in it, probs around 50hp, cheers
How did it go from 53hp to 70hp on stock exhaust and ECU
You haven't explained that
The EU version of this bike makes 70 something HP stock
DNA filter= ++power
This is looking good for the zx6r. Iâm sure itâs gonna be the most powerful 636 ever.
Actually they're lowering the horsepower on the 2024 636 to 124 horsepower down from 128 horsepower 2023 model. It's so it can meet euro-5 emissions and be sold back in Europe again. I don't see why they can't have a euro-spec version and a u.s. spec version
@@georgehgordy1690 it costs way too much money to produce 2 of the same bike like that. Europe is where alot of these bikes are sold whoch is why they bend over backward to get them sold over there
Music. With a SLIPON, not full system swap. Damn I want one of these little beasts.
In Indonesia, we have bone stock zx4rr that has stock 60hp, and when at speed it could reach stock 70hp, yes we ain't have euro4 limitation...
Isn't that amazing...
If only Suzuki made one of this...
I just bought one on the 10th. I need you to work your magic
How much does it weigh after the exhaust and tail tidy mods?
Exhaust difference is probably non existent for the slip on, the full exhaust will drop a ton of weight though
I'd like to see a lithium battery installed also
Kawasaki actually said that these arenât going to be a limited sales item soo take that as you will.
The funny thing is... The stock bike is 79hp... But was detuned for the US and Canada market... So basically you put all that aftermarket things to get less than stock numbers due to your regulations. If that is done in my country it's would hit arojnt 90 odd hp
Amazing well done !!! Amazing
Quiero remapear la ECU de mi kawasaki zx4rr, que debo hacer para ponerme en contacto con ustdes ... gracias
He forgot to mention that the bike does 75 hp stock on the asian market. Congrsts you retuned a detuned bike...
Isnt it because the us gets a extremely restricted version of this ?
ZX4RR brings 75hp from the factory, and 80hp when the intake gets presurized... i don't know how did you manage to get only 50hp from it.
Flashed ecu gets you to 72 to 75 hp at rear wheel. Does slip on or full system add any power? No other mods, love sound of slip on is full system worth it?
I want one of these bikes sooooooooooooooooo bad
The perfect bike for the âwifeâ
My old 440 racing sled still beat it almost 100hp but 2 stroke is just awesome for power mzxz 440 vm 2002
So good, and super smooth!
Everywhere else but america the zx4r has 80 crank hp stock lol
would you have any info on gearing?
I was hoping to get shorter gearing to get more acceleration and torque to give up some of the HP.
Is that possible?
Would I need to get it remapped if I did your ecu tune but then later added the same slipon & air filter after?
Now what if you took out the cat on the stock exhaust system and tuned it? Would there be gains?
thats confusing so a stock zx4r makes about what a flashed and lightly modded 400 makes and oddly enough less tq even when the zx4r is tuned but i still want one.
74 hp at the wheel would be 85 at the crank, that is crazy for a 400cc
Hold on I am no mathematician but the first stock dyno run was 70 peak hp and the video claimed a 4 hp gain with a slip on etc. The another bone stock dyno run showed 54 hp with 50% hp gain with the goodies. I watched this video three times did I miss something? Am I missing some part ware I am not seeing information?
The bike comes with a 5xhp tune for US and Canada. They previously reflashed the ECU to bring the bike up to 70hp or so, like this bike was in other markets. The slip on gave about 4hp for a total of 74.
these new zx4rrs are fucking rowdy
A slip on? What if uses graves full system ti headers would make more 6-7hp right?
50% I should have already had
Pretty sure $1k of fuel burnt practicing might actually produce more smiles. #50yearsofkicks
I'm very confused on why your only getting 50hp stock when the bhp recorded is mid 70's. Bhp to whp you obviously lose some power but 53hp & 24ft/lbs sounds like a modded Ninja 400 more then a zx4rr.
Bone stock hp is in the low 50s
Stock EXCEPT for an ECU flash 70hp
Reading is not that hard.
Quick Fact , My ZX-10-RR weight is less than this bike after modifications
Keep the 10. This is a fun rental bike to abuse. I promise you your 10 will see more mileage than this. Especially if itâs any where near an OG 400.
Subscribed. Great update!
Amazing! I just put a deposit on this bike. My dealership told me that I shouldn't flash the ECU until after my first service. Is that true? Also, does Akrapovic make a slip on for this bike? I own a 2023 Ninja 1000SX and I installed the Akrapovic Ninja exhaust which looks great. Thanks!
You shouldn't flash the ECU until after the warranty expires...
the same HP as the Yamaha R7(74hp)
why does google says zx4rr has 80hp and 35.9nm torque?
Thatâs for the rest of the world, North America gets a restricted 50+ hp version.
I've been saying this to people the whole time who've been complaining about the bike. I've got mine, and I don't feel 1000 bucks is much more to throw at this extra special bike.
I certainly do. And itâs unheard of. No 600 is 80hp unlocked to 110 sorry donât work that way. Most motors or 50% pulled back due to engine life. Every motor can do 50-100% more than itâs out put. The only issue is life span of engine.
I see lots of these motors getting rebuilds in 2-3 years.
@@alejandrotobienne8220 the engine comes neutered because of sound and emissions regulations in the U.S., not because Kawasaki intended to release a 53 hp bike.
So crazy people are having to pay 13k for these bikes with that kind of ECU mapping it comes stock with. I get it is choked for emission standards but good gracious thatâs crazy
