People that do not appreciate a 16k redline arent real sportbike riders

[@forrift7845]

Rpm is nothing but noise without displacement.

[@jakegarrett8109]

@@forrift7845 Its power without the weight. To me they sound great, but I'm used to shifting at 9,500 rpm on a rotary engine, which due to how they fire is more similar firing speed to a 2 stroke where every stroke fires so it sounds more like 19,000 rpm. That engine NA is pretty high power for fitting in a little 18" box and weighing under 250 pounds for a car engine, and they can handle an absolute thrashing (how you need to drive them actually). You can make an engine have a longer bore, but even though its larger displacement its lower power. If you take an engine and make it shorter stroke even though you loose displacement you gain power typically.

[@DrBIeed]

I appreciate it as a novelty but I think when people said they were interested in seeing high revving small displacement cc bikes of the early 90’s make a come back, they didn’t expect to pay full on 600cc prices for them.

[@englishsteel-nz6im]

It's cuz they're all actually a bunch of noobs or with a skillset of a noob tuned to needing the instant torque of a twin to operate the bike--- so many ppl ride a 600 and either get scared off by the high rpm blast past 8k or never wring it out and think it's a weak bike compared to the boring twins that give them torque starting at 2k rpm. It's contributed to the decline of the 600 platform and rise of the p-twins. I'm extremely happy to see a new I4 as I'm an I4 guy. I live for the I4 power band lol. Most riders are interested in: wheelie's and going in a straight line.

Finally someone knows the value of this bike and what it can offer. Also people don't know that Kawasaki had to upgrade their exhaust from the original underbelly to side mount because they had to add another catalytic converter to meet Euro 5 emissions which added more weight. With full exhaust system and lithium battery this ZX4RR will be around 390lb.

[@marcusgeorge1825]

As an ex Australian Superbike racer who started out racing on track in the Australian 250 cc production series (basically full of Suzuki’s RGV-250’s) where the only changes you could do was take all the road going parts off (leaving just the tacho) and replacing the fairings with race fibreglass ones. This was, and still is the best class I ever raced in as all bikes were basically equal and you were limited to the best street legal tyres for all conditions. Luckily, I still have the first out of two I raced. It just hasn’t been started in over 25 years. Purely based on lap times from my old home racetrack being Phillip Island, the cut off lap times to just qualify for racers is faster than what the occasional track day rider achieves on an a new R1 to put it into perspective. Great review Hero and well explained as like Kawasaki did for the inline 4 cylinder 400 Suzuki gave the little v-twin two stroke all the goodies it had at the time. It’s also the same class that most of the Australian World Champions started on when they finished racing dirt bikes. 👍😎🇦🇺

[@teamneverlost]

Australia apparently limited to 25 units of the RR till the end of the year, allocations went within two days. Happy to say I got my order in!

[@marcusgeorge1825]

@@teamneverlost Nice. Out of interest, how much was it “ride away”? Maybe if you’re in Melbourne we could put it against my 1995 Suzuki RGV-250 at Broadford or Phillip Island’s racetracks and swap to get a proper indication to 28 years of development. Considering they are both close in the power to weight figures. For non-Australians, the term ride away means all taxes, duties and 12 months of registration on top of the price of the bike.

[@marcusgeorge1825]

@@teamneverlost lol. It was really stupid that the learner laws back then were simply capped at 250 cc as these petrol/oil burners exceeded learners capabilities (for the majority), hence why they don’t make the cut for the LAMS (learner) system today. As you would remember these bikes were everywhere from 1988-1998. Today unfortunately not many are around as they were either destroyed on racetracks or written off by inexperienced riders. Nothing beats the smell of a cold start two-stroke motorbike in the mornings. As you’ve been riding for some time now what are your intentions for it? It would be interesting to see them go head to head especially as you have experience with the RGV-250.

[@teamneverlost]

@@marcusgeorge1825 Indeed it sure was an initiation of fire learning to ride on an RGV. I had one of the old Kevin Schwantz Pepsi reps, wish I still had one. You're right, they're almost collectors now given the amount of carnage they endured. I was going to keep it as a fun bike to annoy my mates on big bikes with and hopefully track it a bit. A lot of my mates think I'm nuts wanting one as I have a zx6r, but for me I think it will be a hoot! Bit like the old zxr250 and CBR250rr but with more tech and power.

Love the video! Mine is on order for April! I'm coming off a ninja 400 to the zx4rr. I started on a ninja 250 in 2018 and have been riding since! To me, I feel the zx4rr will be a fun little bike that will also be cheap on insurance compared to the zx6r. To me, the zx6r is an amazing bike, but I ride the streets most of the time. I can't use the full power of that bike on the road due to the legal limits. The Ninja 400 has been a blast, but I feel it's just time for a slightly bigger bike. That's why I picked the zx4rr!

[@narou07]

it's nice to hear that, in my country Indonesia, we only have the ZX25R (same looks but different engine). we still don't know if this ZX4R will be sold here or not, even the official kawasaki doesn't want to confirm (looks like they don't want to announce, it will cut the ZX25R sales)

[@IgoByaGo]

I’ll probably get this next year. I bought a 300 when they first came out and had some teething issues. My 2013 ZX6R didn’t have any issues, but it was overkill for me. This is exactly what I want.

[@boxcrashmfg9420]

My only complaint is if it is so track and supersport oriented, why didn't they do a aluminum frame, removal aluminum subframe and swingarm? This could have got the weight down under 400. Also forks only have rebound, but they could have made them with all the adjustments of the ZX6R. This bike should be 7-8k tops with those things. But you are right, regarding the engine and actually doing inverted forks in a 400, Kawasaki got this right, but for 10K i want aluminum frame, swingarm and subframe that is aluminum and bolts up. Forks could be sorted with the right cartridge kit, but again you will be looking at $1k+ for Ohlins NIX, KTech or Andreani EVO's, so make that $9600 at $10-11K before tax and crap. This bike is for me........but at this price without those mentioned things they tease me and think I am a dummy? lol Its like they got 10 foot before the finish line in first place, then stopped to celebrate an early victory. Maybe they will do the next one upgraded with those items......one can only hope. Or Honda brings back the RVF400R modernized and does it right 😉

[@bangocat]

Agreed, when you consider Kawasaki made the ZX6R with a 636cc and aluminum frame and removable subframe starting under $10k just a few dollars more but much more bike in every way

[@taylorb4548]

I’m guessing they don’t plan to sell a ton of these relatively speaking since it’s “only a 400”, and many riders today just want a bike with a large engine to brag to their friends about while it sits in their garage, or for going fast in a straight line.

[@Bristecom]

An alloy frame would be a lot more expensive. Steel has its advantages in durability and feel/flex while only being slightly heavier so I think they made the right choice. However, they should have at least made the swingarm alloy and could have made the subframe removable for easier repair. And yeah, they definitely should have added compression and rebound adjustment for the forks - it's stupid that they didn't as that shouldn't cost them hardly anything extra since it's the same fork.

[@Marques_239]

Because it's a touge bike and aluminum frames are not track friendly because they are harder (if possible) to fix after a crash.

[@gregorygrimm3310]

Making a piston smaller doesn’t save much money. That’s why the cost is so close to the ZX6R. I’m sure the steel frame is the only reason it doesn’t cost over $10k. The people that can’t understand this are the same ones that will complain about the cost of a fairing as it’s “just a piece of plastic “ but don’t see the cost behind designing it, having tooling made, painting it, storing in a warehouse, shipping, other overhead. The ZX6R might be a better value, but where else do you want them to cut cost? And as far as weight, people are also wishing it had a 180 rear instead of a 160. Again, where do you want weight cut? Using fancy materials to make it lighter will only add more cost.

@@quintonbaker4378 The ZX10r is pretty much pinnacle of engineering (where they make race tech practical) and where all of Kawi's R&D goes for sport bikes. The ZX4R is taking shit they already know from the 10R and watering it down to reasonable levels and a smaller package.

When Kawasaki puts, RR ,on a bike, they ain’t messing around. This is the first video I have seen on this bike, that puts its price into proper perspective. I was initially surprised they didn’t go with an aluminum frame, but when I started doing the math myself, I get it entirely. They gave the bike the goods it needs to walk the walk in this displacement category, without getting ridiculous.They already have a couple of those “ridiculous” bikes in their lineup, for those who can muster the $$ Great review. As an ex road racer, who raced Kawasakis exclusively, 500s to 1000s, I totally get what they have done.

[@jeffer1101]

I'm hoping for a Z400RS SE. Basically, the beautiful black/gold Z900RS SE, but with this engine and a lower price. It would be a substitute for the Honda CB400 Super Four that we don't get in North America.

Dude! What an amazing video you have made! I came in with a totally different mind set than I left with regarding this bike. My second ever bike is the Ducati Multistradra V4S and it was so scary and not fun... I am finally used to it and like it, but a smaller bike like this sounds so much on, especially on the track.

[@signal_rr]

Someone pointed out that there isn't a subframe/removable tail section, it's casted as part of the frame. That may or may not mean anything to other people, but for a bike that is marketed towards track usage, it's odd.

[@siraff4461]

For a long time we had makers making the best bikes they could by capacity. Pretty much every category had something with top drawer components. Then the usual bang for buck crowd got in there and it was the usual race to the bottom for quality and price followed by price hikes back to more than before - meaning you're paying more now than you would have for better bikes before. All the best bikes used to be affordable (if not cheap) and the best sellers were often full blown superbikes. Kawasaki themselves used to have the KR-1S, the ZXR250, ZXR400 and ZXR750 - all basically a set of rubber and taking off the road gear away from being full on track bikes. Then there was the ZX range of 4R, 6R, 7R and 10R - again with some of the best components and some of the most powerful engines - each generation getting much more power and higher quality chassis. Then we went through a phase where we've had ever increasing prices and only really electronics to seperate one year from another for around 10 years - all while some of them have been dropped altogether. The inline twin craze is almost an insult to riders. Almost all of them are just commuter bikes with a fairing lashed on. Hardly any adjustability on their low rent suspension and chassis/engines lifted straight from the commuter bikes they're based on. The one stand out is the RS660 - bespoke engine (which is now used in other bikes but it was developed for the RS first), top end components and the full chassis/electronics suite. For me I think the only thing the ZX-4R is missing is an alloy frame to get rid of a bit of weight. On the other hand there are good reasons not to go that way for racing - if a minimum weight is in force for example the extra flex and traction that provides is very useful. Maybe they intend it to race in a category where those rules are coming? Or maybe they did it on the H2 and realised weight isn't everything. I wonder if we will every see a supercharged version...

400 is a better deal, you're going to scape your first one up so a first bike should be cheap. You really you aren't going to be taking it on the track so I don't see why the inline 4 as what you want. Its just so much more expensive, you might as well spend $1k extra and get like 50 HP more than the 4rr with the ZX-6R... At least that motorcycle makes sense. Even a hyabusa makes more sense from a practicality standpoint (those are actually really practical design, but I got my first bike and license when I was 14 and about 90 pounds so likely a busa would be a little big but I probably would have managed). The 400 is such a good deal, even I've considered it (and I'm a lunatic for speed and money is currently no issue, but I wouldn't trust myself with an H2 flashed to H2R), its just really good value.

I've got zx25r for a year now, am happy with it and still enjoying commute and long rides with it, upgrading to 4rr is just a waste for me for i don't go track and use all its power, also my first bike is Hornet 250 4inline...thanks god Kawasaki for bringing 250's inline 4 back to life 😍

Cause it’s cool! There. And thank you for making this video. I’m sick and tired of all these people saying “it’s pointless” most just say that cause everyone else does, they bandwagon the hate on the bike. They hear their favorite little KZbinr say it’s “useless” and they just go with it.

[@Illness.og.]

This bike will be very nice once it hits the dealership. And it’s priced perfectly for what it is. Many just base the price as you stated cause of the engine displacement. Yet they don’t complain about a twin sport bike aka the r7? Only cause they hear “700cc” making less or the same HP as this “399cc” inline 4…

[@RebelRayMoto]

I agree

[@Illness.og.]

@@RebelRayMoto exactly. And this specific one the “zx4RR” is the track and race version. I’m sure Kawasaki will mark down the street versions and base models. This is just the top tier version of the zx4r with all the goodies.

[@RebelRayMoto]

@@Illness.og. Yup, the RR is the top trim, and have yet to release the S.E (Special Edition) and the Lower base model ZX-4RR. In the end, I agree'd with you because the ones that were complaining about it a lot or comparing it to another bike to get, were all based off numbers. Numbers a lone that did not really factor in a lot more things. There are a handful i've seen to get the 6r or compared it to the Aprilia 660 or r7 but I've noticed they missed bringing up seat height factor or the ride triangle ergonomics. I'm definitely sure it's more comfortable riding this than the other bikes it's usually compared too.

[@dinoelasz6360]

This video is so true and I agree with everything you said. However, in the eyes of the average consumer they're going to walk into the dealership and see the ZX6R for not much more money and thing "why not buy the 636 instead?". I appreciate the 4R for being a light track bike, but I see it losing customers to the ZX6R.

[@jamesruch4355]

100% worth it for the track! Honestly the 636 is the best bang for your buck out there. I'd choose that over the 400.

I'm glad Kawasaki made the bike. I just question how many people will actually buy one instead of a 600.

[@glsracer]

I was hoping for it to come in at $8299 but I can see why it's more expensive. I do think your assessment is correct. Street riders will likely choose the ZX6R, people who want to compete at the track will choose the 4R. I was looking forward to the 4R but at that price the fuel range would have to be a lot better than the 6R (like 200+ miles on a tank) for me to consider it. It also better hit a true top speed of 135 MPH (to allow overhead for headwinds and high altitude mountain riding).

We needed this bike, price is not an issue but they droped the ball on the weight. Sure you can get the bike down to 375 or 380 with exhaust and wheels. If it came stock at 380lbs then your looking at sub 350lbs and that would be some fun ass shit. Close to 100 HP weighing less than 350 lbs for 15 grand. Sign me up.

Odd note for the price point but if you look between the 400 and the 650 your already looking at over 16k for both. With the zx4 your at 10k. Its a nice mid point thats more powerful than both for the longevity of ownership. Also thats based off stock bikes not including rider mods which puts you well over 20k vs around 14-16k on the zx

[@Blakezilla594]

@@jakegarrett8109 I have a strange suspicion that you think that "just adding 2 more cylinders" literally equates to the ZX-4RR engine. You can't "just add" more cylinders and think it will be the same. It never will be. Everything is different. Firing orders, transmission case, clutch assembly. The power has to come to one singular point which is the output shaft that the front sprocket attaches to. If you want to see really how much work it requires to modify key components on an engine, go watch Allen Millyards YT channel.

[@jakegarrett8109]

@@Blakezilla594 I'm aware, my degrees are in aerospace and mechanical engineering. I do however love duct tape and have made all sorts of things work that really shouldn't have and have a fondness for the redneck engineering I used to do before getting a degree (you learn a lot by just doing and trying things, then analyzing). You can relatively easy run 2 engines to a single output, OR you could do something like have one engine drive a left sprocket and the other a right sprocket (very easy to do with 2 strokes since you only need to adjust where the ignition is to make them run backwards, but still not impossible with 4 strokes either). Easiest way with 4 strokes is to have 2 stacked sprockets (just like your pulleys are stacked on engines for driving alternator/fan/water pump/etc on old engines) and have 1 engine sitting right above the other with about an inch more left and voila you've got a standard wheel, standard engines, and only thing you had to do was weld some spacers to stand off 2 sprockets. Easy. I've also got a couple front wheel drive motorbikes that I've designed and they work fantastic, so really you don't even need the rear wheel to be driven, just saying.

These kids on some "its not enough power, it weighs too much" are LOL.

It will be interesting to see what kind of power these can make with an full exhaust and a tune. I'm really looking forward to the reviews.

Being able to get out to the best roads and back can be a struggle in Colorado, Wyoming, and Montana. Fuel range is important.

Spending more money on a 400cc that costs 10k when they already make a 12k bike that has more power seems foolish to me.

@@user-360johnn I agree to an extent. It's likely that there will be a reasonable gain from just a 350 dollar tune. Adding a full exhaust on top of that would be for the weekend racers.

I 100% agree with you, Kawasaki IS the new Honda. They are today what Honda was back in the 80's and 90's, the only brand pushing the envelop and invocating and advancing the motorcycle industry. Between the supercharged H2 and it's variants, the new small displacement 250/400 4-bangers, and the recently announced plug-in hybrid and hydrogen bikes, no other manufacturer can touch them at the moment. I'm super sad that Honda fell into obscurity, other than the CRF450RL I cant think of a single model that I'd choose over the competition. I'm not a fan of Kawi's current design language, but the new ZX10r is growing on me, and I'm truly excited for what the brand is becoming as of late.

Great post! Simple weight stripping mods and a flash tune and I've found my dream bike!

[@jacquescrusan9500]

A quick breakdown on how/why the ZX4RR weighs 50 lbs more than the Ninja 400: - thicker, more strengthened engine cases to deal with higher internal stresses, forces and loads, along with having a longer crankshaft with more pistons, connecting rods, cam length and valves to deal with. - a heavier-duty rigid frame structure derived from the ZX6R platform - heavier-duty, larger diameter front forks and rear shock to handle significantly higher speeds, accelerating forces and braking forces - heavier duty chain and sprockets to deal with significantly higher final drive torque output. the ZX4RR is almost guaranteed to have a larger overall gear reduction ratio from the engine to the final drive due to its significantly higher operating RPM range. - more purpose-built wheels, along with larger and more brake rotors and calipers as well.

[@180FiftyFive]

why does the zx4rr weigh more than any of the old 400s from 20-30 years ago?

[@HifeMan]

@@180FiftyFive I don’t think they had to hit euro 5 emissions 20-30 years ago. Lol This thing has 3 catalytic converters. So that exhaust is gonna be way heavier.

[@180FiftyFive]

​@@HifeMan ABS adds 4-8lbs. a full race (non-cat) exhaust system sheds about 13-14lbs on a euro 5 4-cylinder bike. a zxr400 from 30 years ago weighs about 390lbs so add the 22lbs and that almost equals the 416lbs of the zx4rr. but 30 years of technological advancement and there's no shed weight anywhere else? don't get me wrong, i still love the idea of this bike and will probably get one when they come to europe, but its still strange that its so heavy. they could have made the RR variant to accommodate one rider instead and shed a few kilos on the subframe? but yeah aftermarket race exhaust, tail tidy and a couple other mods might reduce weight considerably

[@DerSpeggn]

400cc is the limit for the "small" motorcycle license in Japan. Wich is why you often see 400 versions of popular bikes. This is no exception. It is targeted to people living in Japan, wanting to ride their bike on the twisties and go to the track as well. In Europe or the US I would rather take a 600cc bike over this, since the licenses are not by displacement of the engine. If there were any new 600 supersports on the market, but I guess that segment is gone... Maybe something like the R7...

[@consciouslasagne354]

Also you can't beat that inline4 scream man

[@BeginnerMoto]

I think this bike is a good step in reviving a market segment but I believe it weighs and is priced too closely to other 600 cc bikes. The Aprilia you mentioned is lighter and more powerful than the zx4r without being that much more money. Kawasaki does have a vast dealer network and is known for their reliability.

[@sugonmadyik6222]

I live in Indonesia, the true reason why ZX 4RR is almost 10K dollar in your country is because the bike ZX 25RR price is 6K dollar in my contry, if Kawasaki maybe sell ZX4RR it for 7K-8K it will destroy the market and people will chose ZX 4RR instead of ZX 25RR. So overal its about market.

[@jdamage5002]

The reason I believe they didn't want to make a 400cc inline 4 is that it doesn't make any sense for Kawasaki to spend more money on the heavier engine and more moving parts. More moving parts equal more maintenance, all this for only 25lbs of torque. So they try to offset it by selling it with leftover suspension components? Mild suspension upgrades, NOT racing suspension. Mild brake upgrades, still not racing spec'd. No Ohlins, No Brembo, No DDC, Not even steel brake lines. But a Premium price? Pay for the Squish huh? This IMO is not a race-oriented bike, it's Race INSPIRED. Which means class stock racing or track day weekends and street curves. But if I started on a Ninja 400, this would be the best next upgrade, then onto something with double the torque. Great stepper bike IMO... But we'll see...It's the motor sound that is going to make is sell.. Honestly, they should have made it electric...lol would have been faster.

[@jamesbashaw5831]

Too bad they chose to build it with a steel frame. I, however, have a spare FZR400 aluminum Deltabox frame in the shop. Now to wait until someone's insurance totals their new ZX4R and I can swap it all into that frame!

Will they just make a ZX4R with the new ZX4RR that has a bit less track features but more street features that will be a lil cheaper like $8000-$8500 maybe less that might be a good idea as a more street bike ish option than the full on track option which is the ZX4RR

I would rather the Aprillia RS660, but the insurance on that is absolutely insane for something not classified as a supersport.

[@dorayaki5494]

It would be an amazing bike if the price wasn't nearly the same as a i4 600 sportsbike. It would be even better if it actually weighed in less aswell. But it doesn't. And it lacks what I consider to be the most fun part of motorcycles. A high torque power. If you get a 600 you'll be better served in my opinion. The ZX4RR costs nearly 11.000€ where I live. I'd put it in the 6000-7000€ bracket. That way it would be more competitive against the 600's.

[@Ahrimas]

It's a mini superbike, it's not a budget sport-tourer. I'm glad they've gone hard on performance. Obviously I'm not gonna buy one, I don't have 10 grand to spend on a toy, but I love that someones going to and scream around tracks on the weekends.

[@andrewstambaugh8030]

That's a very fair comparison. Although, as a manufacturer, they don't need to spend on the original parts for comparison. So I would have liked to see this end up the low $8K price range. While that might seem low in your comparison, at that, I think this would absolutely become the de-facto bike - trouncing the competition in sales. At it's current price range, I am a little worried it will get just low enough sales for there to be a risk of them to pulling after a few years. PS this is absolutely the bike I am looking for - for daily riding! If it were priced as I had hoped, I could easily sell 1 bike and add a bit to get it. At it's current price, it's a bit more than I can justify splurging on (will be saving up that splurge budget instead). I wouldn't be at all surprised to see these used 2 years from now still hanging at above $7K, because people won't want to get rid of them.

[@lh5943]

Reminds me of my old VF500!

[@positivevibes532]

The fact that the 600 is only a grand more makes the 400 way less appealing. If they priced the new bike at around $7-8k it would be killer.

That torque is quite low. My cb400 makes much less hp, like 55, but high 30s in torque. Really hoping they bring it back in a new and greater form to the global market, as it was pretty criminal how they barely sold the cb400 outside of japan.

[@adobomoto]

To your point, if this bike is made for track riders who want a "slow bike" to go fast on and will spare no expense, the RS660 for $1800 more is the better choice. It has the liter bike IMU with Race ABS, and other electronic things that come with an IMU. The RS660 is much lighter and the 80% torque at 4k rpms gives it a better overall performance in the rev range. And to add to the reliability portion, track riders hardly care about blown motors. The warranty on both bikes are similar and the bikes will both break at the track. The RS660 is the better choice for the track. But I think the zx4rr is also a good bike..I just don't think it has enough value. If the power to weight of the zx4rr is better than the ninja 400, the power to weight on the RS660 is even better than that.

I was always a Yamaha Fan with Honda and Kawasaki and Triumph close second depending on what one is looking for..
