Вставка
- Опубліковано 6 сер 2024
- We take the brand new Kawasaki ZX-4RR out for an on track first ride review. After trying this bike on the street earlier, we tried it again but this time out at the The Ridge Motorsports park for a trackday test. We also review the ECU reflash from @2wheeldynoworks and slip on exhaust from @GravesMotorsports . How do they change the way this bike performs? Watch and find out!

Love it. Thanks for sharing. In-line 4 400cc is one of a kind. It will be displayed in the hall of fame room in about 20 years. By then, you will wish you have one sitting in your garage.
Better order two 😂
Thanks for sharing. Glad to actually see someone riding one on a circuit instead of just doing top speed runs on a highway and saying "jUsT bUy a 600!".
You should just buy a 600 . This bike weighs close to what the 636 weighs. For almost the same price 😂🤦🏽♂️ . Waste of money unless you truly want to ride around a 400 forever ..
@@4npushap352exactly it doesn’t even rev higher than an r6 or weigh much less what’s the point just get a proper 600 at that point ur buying a worse bike just for the fun of it at least a ninja 400 or r3 weighs less and makes a bit more sense
Well at that point of stupidity, r6 isn’t that lighter compare to r1 variants. Then go for a R1….
Damn muppet. Let people enjoy the efficiency, basic sportbike that we all miss. No electronics or overpower, tho performance that are plenty for road, and a great tracktoy that will allow you to learn.
@@4npushap352 Yeah I was going to buy one but kept going back and forth and couldn't justify their pricing on this bike. Ended up buying a 600cc. It's a cool bike just not worth 12k + mods and tune to get it where it should of been from the factory.

Crazy how in the land of the free, this bike comes with restrictions on it. I'm looking to buy this bike in Japan where I'm currently living and as far as I know, it will be available without restrictions when it comes on sale in Autumn.
I agree that’s it’s frustrating, at least it’s an easy fix with the ECU flash.
Here in Australia it’s going to be released with no restrictions. The stupid thing is that it would actually be worthwhile to release it as a restricted bike here as then it would have a wider range of potential buyers.
In restricted form it would comply with our Learner Approved Motorcycle Scheme, thus it could be bought by people on restricted licences as well as open licences. Seeing as it’s only going to be released in unrestricted form it’s only going to sell to open licence holders.
Land of the very woke, remap it to a ZX 25RR setting for 18,000rpm .___.
@@David-lr2vi Any idea what we are going to be paying for one here?
@@mmontalvan1848 Well that will probably grenade the engine as the pistons are bigger in the ZX4R so probably wouldn’t cope with the extra rpm’s.
First usa track video im seeing. Thanks for upload. Seems like a true track bike
It is an amazing track bike. Constantly in the high-revs, quick maneuvering, and the quick shifter makes frequent shifts a breeze.
Awesome vid! Great work Tyson as always.
Thanks!
what a beautiful sounding bike! an instant classic
Nice job, great review, definitely building one for my next race bike in 2024. Nice to have a track review, not a squid review.
sick bike on a sick (local) track, like xmas morning over here great vid dude!
Thank you!
Will be picking my bike up sometime this/next month am super pumped, really happy to see people were able to unlock the ECU for reflashing, definetly going to be looking into that once mines broken in.
Highly recommend
That bike sounds so smooth. I really dig it. Good riding.
Love it, man that track looks SO good and fun!, I bet that guy on the BMW at 4:20 had to think to themselves... "Did I just get walked by a 400?" lol Making me want that bike even more! And I have a modded H2 SX that is 260 to the wheel, just something about wringing the nuts off a small bike with a big smile from ear to ear!
oh damn, i wish i would have stopped by last weekend to see the bikes! that's my home track, i live down the street! great to see a track review of the bike though, this bike needs a tune and a track to justify it's existence unfortunatley
Pure sound on track footage next?? Love the quality content ur pumping out!!
Thanks man, I can put a pure sound session out on my other channel
I know I should just buy a 636, but there is something so appealing about a tiny inline 4.
Great video, great bike full stop!
Thanks, the bike is amazing for sure.
This was the video I was waiting for! Thanks so much! Did you make any changes to the fork?
No changes to the stock settings.
Nice video man
Thanks!
Would love to hear thoughts on the components.
Stiffer, got it, but are they adjustable comp/rev/preload? Any idea on the spring rate?
Adjustability for the rear shock.
Thoughts on the electronics package (TC, wheelie control, power modes, etc)?
Thoughts on abs? Personally I hate abs for the track, but that’s also because my track bike had abs that interfered far too early with no adjustability so I removed it.
Weight? I realize stock it’s over 400 pounds which is kind of a let down for a small bike, but you can have a 400+ pound bike still feel light with good balance. The 2009ish cbr600 comes to mind.
Thoughts on any components that are probably going to need replacement right away? Are the rear sets too low for track? Are the bars or levers uncomfortable for track? Is the braking system good enough on track?
For context, I street and sometimes track my gsxr750, and track only very regularly my built R3. I’m not one to look for just power, I much prefer a smaller lighter bike on track.
The front suspension has preload adjustment and it was adjusted to nearly maxed out. The quickshifter works very well, but haven’t tried out the other electronics (tc,abs).
The bike felt light and nimble, perhaps a lot due to the 160 rear. I thought the stock clip ons were really nice and not needing replacement. The pegs do scrape at apex occasionally and I would probably get some woodcraft/vortex replacements.
Braking felt great compared to the 400. It would be easy to swap out for a better master cylinder. Maybe a radial Brembo.
Overall it didn’t really need much besides rearsets (after pipe and reflash).
Great review! Still wouldn't spend $10K on it! And even with the exhaust upgrade it is still heavier than the Aprilia RS 660 stock and wet.
Hi, loved your video, would you mind letting me know what that mount you are using to mount your 360 camera on the rear?
Yes, I listed the Amazon links in another comment.
50 hp to the wheel new? Thought it would be way more. Would like to try with 72 that could be fun revving it out all the way but not worth the price with the 636 just a little more.
What selfie stick and mounts are those for the camera? Been trying to find a way to get good 360 shots like that with my insta 360 one RS but hard to find something sturdy and reliable.
The selfie stick is: www.amazon.com/dp/B00MYJENXU?psc=1&ref=ppx_yo2ov_dt_b_product_details
The mount to the passenger pegs: www.amazon.com/dp/B07TNH72SG?psc=1&ref=ppx_yo2ov_dt_b_product_details
The adapter for the Insta360: www.amazon.com/dp/B083JTGBS2?psc=1&ref=ppx_yo2ov_dt_b_product_details
I also used a small bolt in place of a Gopro mount screw: M5 x 1.00 (Home Depot)
Re flash ecu with stock euro specs from factory 80hp on par with r7 yamaha, for 400 that is staggering
Picking mine up this weekend! What track is this?? Looks great for every kind of bike!
This is The Ridge Motorsports Park in Washington State.
Nice Tyson! Do you know what race class that will be allowed in? It seems too fast for ultra lightweight but seems like it’s too slow for middleweight. Thoughts?
I don’t think any classes allow it at the moment. It would be nicely matched up against twins cup bikes (R7, SV650, etc.)
@@TysonMoto 4RR is allowed in 450 superibke class in AFM in NorCal. They race against cripple triples (3 cylinder R6/GSX-R600) and old school FZR400.
Just wait till you ride a 636.
13' 636 here. Graves exhaust. Sounds good man. Have fun ✌️
636 feels much heavier and bulkier despite what it says on the spec sheet. I have both 4rr and 636.
636 is an awesome bike. I love the additional power from the extra 36cc.
@@piasob Every time I sit on a 600 at the dealership, I immediately say "no this isn't what I want". The zx4rr is smaller feeling and not as extreme.
Hey there..
What is the jointer / mount you placed below seat to hold stick. 00:30

awesomeee
I have a 91 Suzuki Bandit 400, I’d love to try out an uncorked one of these, 30 years of technology updates, I can only imagine.
That bandit 400 is an awesome bike!
I want one!
I qonder if we can just buy a jaoanese oem ecu. I thought it qas supposed to have a bit more power thab what 2 wheel got out of it
I have the 40th anniversary edition on order and I don’t plan to ever get rid of it. It’ll be a collector item one day.
I think it will for sure
How tall are you? And does it feel like a "larger" bike vs ninja 400 as far as ergonomics to you? Thx
I’m 5’11. It feels more like a Ninja 400 size wise than a ZX6R. It does feel slightly larger than Ninja 400 though.
Cool but I need a bike with a more forgiving rev band for some of my questionable shifting into corners 😂
This bike is so smooth you can shift pretty much anytime and it doesn’t upset the chassis. It does require lots of shifting, which I really enjoyed especially with the quickshifter and autoblipper.
Have you rode the R7?
what do you say about the stock tires ? any other mods to the bike yet ??
The stock Dunlop GPR-300 tires did well at the track and they are great street tire as well. I would recommend swapping them out later for something a bit more performace focused, Dunlop Qualifier Q5s for example.
Is it a stock exhaust or aftermarket, it's sound good
Graves slip on exhaust
I want to get this just so Honda can a be a little closer to making another baby blade. Bring back the 400cc bike wars!
I’ll take the first Gsxr 400
Hi!
Thnx for this awesome vid.
Im about to get my first bike.
Which one would you reccomend.
(I will mostly do streets and drive speed limits)
Ninja 400, zx4rr or duke 390?
Bye!
Depending on your budget I think any of those would be a good choice. I would go with a used Ninja 400 just because of price.
@@TysonMoto thank you!
Regarding the second hand ninja400, any year that is preferable?
And do you have any experience with quickshifters on ninja400?
I dont think its mechanicly possible right?
(I subbed btw)
@@sixstab2967 2018-2019 had clutch issues that had to be fixed with aftermarket springs and pull rods etc. and a quickshifter is possible but not a autoblipper
@@BooStairs thnx a lot for your respons!!
I will avoid those years and look for a model after that.
Is it weird to drive with a quickshifter but not a autoblipper?
@@sixstab2967 Heal Tech makes a good quickshifter for the Ninja 400. It will allow for clutchless Upshifts only.
Is the decal on the exhaust removable?
Not sure.
I wouldn't be surprised if the other manufacturers bring bk the inline 400cc bikes
I wish!
It is nice but I was kinda expecting it to be a little lighter for a 400. I'm guessing that dealers will be asking well over msrp so you could probably get a new 636 out the door for about the same...or less.🤔
I felt the same way initially. But after riding it you realize it’s such a unique motor at 400cc. The way it builds revs and the quickshifter makes the experience different than any inline 600. It also feels light with the 160 rear tire.
@@dg8062 I wish it was my bike, my buddy got the first one from his dealer and invited me to try it out. As for 2wdw, they seem pretty cool, have not worked with them directly myself.
Nice buddy, enjoy those track days at the Ridge. I've thought about it but I'm now 62 and have a mt10 and a new gen mt09. The thought of a high side and hitting that pavement at my age isn't too appealing, broke myself up on dirtbikes growing up enough. Have fun!
Exactly. If it came out the box lighter than maybe it would be okay and maybe if they didn’t ask the same price for a zx6r. Definitely cool looking but not worth it , to me.
Anyone thinking about buying this over a 636 is a damn fool.
I’m a noob so I apologize for what you may perceive to be a dumb question. I just started riding. For reference I’m 41 and just got a 4RR last week. Can you tell me what an ECU reflash means? Does it void the warranty? Also in your opinion, does riding on the track more than the steer make u a better rider overall?
ECU= Electronic Control Unit
It’s the computer that controls the bike (like fueling, RPM, sub throttle plate, etc.) and a ECU flash changes perimeters for the engine and and fueling and whatnot. You’re essentially just taking out EPA regulations on the bike and engine to get what the engine was supposed to be before EPA regulation requirements, and I’m pretty sure it voids warranty but I could be wrong for the ZX-4RR, and riding you bike on the track will make you more comfortable on you bike (ie understanding the limits instead of always guessing where they are at) so yes it makes you a better rider in the sense of understanding your bike but also you won’t be riding on public road like you’re on a race track
I hope this helps!
Well the ZX-4RR is designed by Kawasaki to rev to 16k RPM and produce 80 horsepower. In the US and Canadian markets the ZX-4RR is restricted to 11.5K RPM and about 50 horsepower due to noise emission laws. When you reflash this ECU, you bypass the 11.5K limiter and return the bike to its intended RPM limit and Horsepower levels. There is a great video from 2 Wheel Dyno Works about their reflash for this bike, I'll link it below. You can simply remove your ECU and mail it to them to reflash and they mail it back. Does this void the warranty? Perhaps, however I would not be concerned about harming the engine as it was originally designed for this.
ua-cam.com/video/OKvSCrwZMic/v-deo.html
@@TysonMoto Also if needed they can probably reflash it back to factory specs.
@@revelationrider6913 it does thank you so much for your response. So is an ECU Flash the same thing as a DynoTune?
@@TysonMoto thank you for that. Just outta curiosity, how much does it usually cost to reflash a bike?
Can anyone compare this to a 2001 zx7r for a track bike. Thinking of Selling the zx7r to get one of these any comments would be greatly appreciated
id buy one 2nd hand as a track only bike, in a couple of years when the price is cheaper on used market. will be better on fuel and maintaince cost compared to a 600. just cant justify 10k on it currently
Hopefully they release the ZX4R for the us market. (They have it in Canada). It’s a bit cheaper.
@@TysonMotobut bro is it worth it the 4r in canada has no quick shifter up and down for the price?
Did you work on the forks yet? Man they are soft. I think this will be high on my priority list of mods.
The preload is adjusted way up.
@@TysonMoto I did that too and it helps. If I can find out what fork oil wt is in them I'm going to try a heavier oil. At least until someone makes a kit for them.
@@chickentuber a friend is having GP Suspension develop a cartridge kit for his stock forks next month. They would be available from GP soon after. Probably mid to late June.
Where can I get this selfie stick Mount
I posted Amazon links in another comment.
dude the audio is low af, do tend to it next vid pls ty, supperb video
What? You guys had the ZX4RR with only 50hp stock? We Indonesian got them 80hp stock
Yeah US is limited to 11.5k RPM from the dealers.0
@@TysonMoto So does that due to regulations or is it eventually will fully open the limiter as it reach break in period?
Aside from you remapping it
@@jeeewhyyypheee it’s due to noise emission regulations. It stays on the bike forever unless you reflash.
@@TysonMoto What a silly regulations 🤣. If it stay that way, it wouldn't make any different from ninja 400. Bike so powerfull hp per liter, goverment had to nerf it so bad
Awesome bike. It's not lighter than a 600 though. Really wish they made it with an aluminum frame. A race prep 600 and race prep 400rr will weight the same. My rs660 is lighter than this, that is stock for stock or race prep vs race prep.
Yeah i get it. But thats a nice i4 👀😇
Its different. And even if rs660 is a sportbike its not « supersport » while this one is, and r6 was. Again, rs660 could be mod to be supersport styled.
Now it comes down to personnal preference but i love i4 and get kawa over rs (that my bro own… might help too xD )
I think you can buy a carbon fiber ZX25R frame. Got money?
@@xorbe2 lol ofc xD
But i have to admit this sound and bike hype me much more than twin parallels engines…. So boring 😅 except aprilia v4 ish sounding one
@@thomasbouvier3203 yeah I hear you, for instance Street Triple is not my favorite bike overall, but I ordered another because that sound, I miss it.
@@xorbe2 rn i m going for mv brutale 😅 my fzs6 died and that sound will leave forever an empty space in my heart. Prefect sound with leovince suppressed
How is acceleration? Blow you away or meh?
It feels and sounds like you’re going much faster since the RPMs are alway bouncing off the limiter. It was a ton of fun.
@@TysonMoto Cool can't wait to buy one if there are any left. Do you know if there is going to be more coming to states this year?
@@UltimateEnd0 I have heard a rumor that Kawasaki is producing a second run for this year now that the first shipment has been received well.
@@TysonMoto WAHOO! That's great news thank you very much for this info, I looked everwhere for this.
@@UltimateEnd0 I drive a truck for a living. I go to plenty of powersports dealers across the country when between loads. Every dealer I've talked to about the ZX4RR have more or less all said "oh yeah we ordered a few in the beginning of the year, they're already sold, should be coming in soon". I've also hear about production being ramped up. Kawasaki seemed really timid with the release of this bike in terms of production. Can't fault them; the bike is a bold move into strange, wonderful territory.
Kawasaki has sold every last 4RR. I think it will be a slam success, but will be more of a niche bike for seasoned riders more so than newbies due to MSRP.
What track is this?
The Ridge Motorsports Park
I hope kawasaki brings the ZX25RR here as well and maybe honda brings their cbr250rr..
They won't, sadly. This is based on the ZX25 chassis, and they still had to put it on a full steel frame to justify the cost at 400cc. the 600's will get this new gen tech upgrade soon and likely kill the zx4 in my opinion. I was just talked to the dealer the other day (in canada) and they said the 4rr will likely be out the door around $13,500 (10k USD). the 25r gets the same stuff but half the power, it just won't sell in a market without CC restrictions. could always import one of the old motors from the 90's and swap it in, lol.
Not bad for a mini 636
Really pleased that Kawasaki have brought back this brilliant class… memories of the original ZXR400R, NC35, FZR400RR etc… My only criticism is on the looks. I wish they could have chosen a different paint scheme.. it looks just like the other Ninjas. Just not a fan of black wheels..boring 💁🏻♂️
Well maybe they will do variants… i ve heard on the web a z400rs might come. Tho a gpz900 on 900rs was « leaked » ^^ so…
I think R6/R1 looks are objectively the best.
Someone tells me the sub 1.5% weight reduction from the exhaust is indeed in your head :p
Just a reflash and exhaust would do alot of improvements.
Agree 100%
ZX-4RR or R7?
Zx4rr
nice nice cnice
@7:05 🤣
Now if we can just convince Kawasaki to use an aluminum frame with a rear subframe it will be the PERFECT bike!!! Like 390-400lbs stock 🎉🎉🎉. Put lightweight aftermarket goodies 😎 Get it down around 375lbs and 80hp!!! Winner winner chicken dinner. Be hurtin 600’s feelings on the track and embarrassing some liter bikes 😂
That would be amazing. Maybe Suter can make a frame/swingarm for this motor
@@TysonMoto great video 👍 it didn’t look like you were pushing that hard and you were still blowing by them guys 😎😎😎. Watch out there’s a new mightymouse in town and it’s called the ZX4RR
soooooo I found my new track bike!
I just boughtine yesterday after buying the standard 400 6 weeks ago. I was told zx4rr would not be availanle until Fall, so i bought the standard. I went to the city yesterday on s birthday run and to look at dual sports and found the Unicorn zx4rr staring at me when I walked in. I bought it cash and went immediatley home and rode until 3am. If the 400 is a Camero the zx4rr is the Corvette
The American version has only 50hp? I thought it was going to be 78.
Yeah it’s US and Canadian versions. On the Canadian Kawasaki website it explains that it is for noise limits.
@@TysonMoto Damn, at that price, i would be wanting more power.
@@sossteve66 luckily it’s easy to bypass with a ecu reflash.
400cc and 72hp !!! OMG
Dash lies, it's just over 15K rpms, nowhere near 16K. Unless your flash fed you a limiter change. That S1000RR pass at 4:20
Lol I don't think so. They took one of these with 1 mile on it and dyno'd it at 41 horsepower
This has a reflashed ECU and Graves slip on.
I loved the idea of this bike so much but I think it’s priced unrealistically in the US market. To be only $1000 less than the 636 makes it difficult for a buyer to choose this over the larger displacement ninja. I also think it’s completely unfair to compare this to the ninja 400 because it’s almost twice as expensive, and not meant to do the same things. The ninja 400 is a beginner bike, where this is a beginner race bike. Obviously this is just my opinion, but I think if this was priced more like $7500, it would be in a sweet spot below the 636.
On god brother 💀 I’m so confused right now since they both cost almost the same 🤦🏻♂️
They can't price it that low because the suspension and a few other key features are actually significant improvements over the ZX-6R, in line with the ZX-10R package. The real question for this bike is how well can it be chopped up. It's going through 3 catalytic converters making that horsepower, and the engine is likely very overbuilt judging by the weight of the bike. It's possible that we could see some truly insane street-illegal builds on this platform.
The swing arm og 636 looks nicer
Why would you buy this thing? It weighs as much as it’s big brother ZX6R.
4:23
ZX4RR beat S1000RR on pace alone😂
*jk
Tyson is a pretty good rider. I was surprised he was letting off and braking that early for turn 1. I think he was just being nice to that BMW rider lol.
Move your shoulders dawg, not just your knee and hips
This bike is gutless just get a 600 guys.
Someone who can really ride that 400, will lap you on your 600. Guys who want 400s for the track are not cross shopping 600s. It's a different class dude. Head to the track someday and you'll understand.
@MalShakur dude put the same guy on the track on that 636 and the guy on the 400 gets lapped 3 times. for the track that 400 is pointless unless your youth class. For the street it's OK if u got stupid money and want to waste it.
The 400 is cool but it's only cool if there are no bikes to compare it to. The 600 revs the same and has 50 more hp and double the torque for 1k more in price.
I understand perfectly the 400 is for guys afraid to go fast
600’s are gutless. Lol. Want a bike with “gut”? Don’t get a middleweight.
My 750 sends its regards to your 600/636. The 848’s, literbikes, 1199’s etc all do as well.
Oh, see the similarity? Anything smaller than (insert your class of bike here) will always be called “gutless” in comparison.
Well if u want a screaming inline 4 you get a 600. Liter bikes don't Rev that high unless u rework them. The 400 is fucking pointless. That's my point. I can guarantee you I could play you audio tracks of both the 400 and the 600 being rung out and you'll say the 600 sounds better every time. They sound like 4cyls running at 14k plus. But the 6 will sound meatier and also be going much faster
@jason sarmiento your 750 suzuki is marginally faster than a 636 if atall That's on the track or on the dragstrip. It's gonna come down to rider and setup
2 flaws 1 needs to be an aluminum frame its too heavy 2 needs to not cost 10k 6-7k is where this bike should be
wonder if the zx4rr will be able to compete in the current 300/400cc classes of racing?
If it did it would dominate…
Everyone knows, or should know that Ninja 400 has absolutely nothing on a ZX4RR. 400 is a novice bike, nice street ride, friendly, etc. zx4rr is a small engine track bike with somehwat street friendly ergonomics. Sounds unmistakably Kawasaki, just wish it was more than just 20 pounds lighter than the zx6r. Anyways, hopefully I get my hands on one for myself too!
