Ninja 400 Racebike Walkaround Review

[@oh_zoinkers]

I bought this bike in February. Love it! Already put nearly 6000 miles on it

[@xzavierroman3949]

instablaster...

[@oh_zoinkers]

​@@xzavierroman3949 I still have the bike to this day with like 15k miles. It's so slow now compared to upgrading to a 2007 R6. Still a good around town bike. Going to sell it soon

[@fuego4409]

@@oh_zoinkers whats the tire size?

[@oh_zoinkers]

@@fuego4409 No idea, using what's recommended by manufacture and Dunlop brand

[@Tiagotaf]

how much does it weight ? I'm curious at how much did they shed of the road version.

[@robbieracer3294]

I love how people don't understand the point of building a smaller bike. They are like...just buy a H2 and race it!! I can build a 600 race bike that will smoke this. Yea..I'd hope so, but can you riding it? But, some people want to race in a different class..some want to save money and have it done right. Sure, you can buy a 600 and throw it on a track with only brakes and pipe perhaps...but these little bikes, you can do a lot more for the price of a new 600.

[@marknasia5293]

The 300 series bikes are becoming more popular and that is exactly why Kawasaki responded to the need with the 400, i agree with you and so does major bike manufacturers...

[@TheVanquisherGaming]

Agree ..also these so called little bikes are capable enough to get you out of tricky situations, it gives you enough fun on open highways , gives better mileage also if not ridden carefully they can pass you to the other side( after death).So these so called little bikes are actually much more practical. Litter class bikes are strictly meant to be on the tracks only but people made it like these litter class are the real deal....pity on them.

[@danejurus69]

I have a 400 and a 600 and I'm race modding them both out. 😁

Ninja 400 is a great bike

[@mountainthrasher500]

It’s pretty awesome to watch Jeremy Toye back it in to turn 2 at laguna and ride around everyone-- on a 400!

[@sportmuaythai]

Glad to see you moved over to Ninja 400 for racing. Ninja 400 is romping at race tracks in Thailand. Yesterday I was reeling in 2018 RC 390 again and again effortlessly at Bangkok kart track.

[@wuzihuzi]

sportmuaythai it's not his bike.

[@Edward-kv8re]

We need to hear what it sounds like!

[@LueXiong10]

A lot of people are investing in small bore racebikes now! Thanks for the awesome vid!

[@angelocardoc]

Put that on a dyno. I'd love to see the HP and TQ chart And I want to see Ari do his best lap on it at Laguna Seca. Then do a comparison with Ashton Yates' record setting time.

[@jeriksson7686]

People doesnt understand how fun it is to ride smaller/lighter bikes. I had a blast when I raced Honda 125GP! Would love to try a SSP 300 class bike.

[@craigmacfarlane4686]

Show us a hot lap Ari! Great vids. Keep up the superb work and thank you!

[@beanwithbaconmegarocket]

I'm building an r3 race bike. Where the money really starts to hurt is all the lightweight parts.

[@AriH211]

Ayup, those aluminum and ti fasteners really add up!

[@authenticmax6350]

Why do you want to waste money on a R3 ?

[@AriH211]

Probably because that's what he already has.

[@beanwithbaconmegarocket]

Authentic Max lol relax dude. Bc I could buy a slightly used one for 2800 and just throw a little money at it here and there. And they're fun as hell. I was just at MotoAmerica in Utah last weekend. Lots of r3s in the paddock haha

[@authenticmax6350]

Probably.

[@markmtbrider]

Most fun I had during my wera days was on a rd 400. This thing would be a blast to wring it's neck around a track with 12 other guys doing the same. Find out who the best at finesse and corner speed real fast.

[@e30gangsta]

That's because rd's are life.

[@smithjones1906]

On every video featuring a small bike, there's always someone saying, "in India, this is a big bike!". Okay. We know. Get it tattooed on your forehead.

[@aishwaryagaidhane]

I'm an Indian biker, I just liked 'that' comment and saw yours. But your comment made me crack hard! Seriously. 400cc+ bikes are getting common (or maybe i ride one so i like to think that?) Anyways, cheers man, have a nice day! PS its not a smart choice to go anything above 200cc around here, our streets are small and chaotic with slower traffic.

[@CollinMac96]

This is a pretty big bike here in india

[@aishwaryagaidhane]

Collin Mac lol. If you are trolling and you're not Indian then this is a pretty rare, high maintainence & pricey bike for india. Whats common here, comparatively in this segment, is a cheaper, hence heavier, sohc variant of the duke 390, dominar 400. And then there are the Royal Enfields out there with 350cc+ motors.

[@ABC-wv3uc]

Im from india and i will say this is a pretty big bike in india

[@BritishBikerPhilippines]

It's legally a Big Bike here in the Philippines...........in my unwanted opinion, for these roads it's big enough.....tricycle drivers, potholes, shingle, goats, kids, crazy suv drivers, the list is endless lol

[@ripmax333]

This guy really loves small displacement bikes, especially to race them. I dont blame him, they are fun and accessible to every one. In Uk there was the 500cup, I wonder if it's still exist, they used Honda CB500's which were also great bikes to race with.

[@mannyechaluce3814]

More fun to ride a small bike fast than a big bike slow :D

[@tysoncott7402]

awesome! kawi knocked the ball out of the park with the these 400 ninja’s. the 250/300cc class are still ok bikes but 400cc is just right for new riders & they have something to work with once they get there skill level up.

[@Janggo1911]

Motovlogger from the Philippines here. Definitely a big bike here. MCN is weird without Ari. Still a good channel.

[@menom7]

As I've said,ever since I started riding on two-wheels 25 years ago.................I'd throw a leg over a smaller,lighter,quicker (but not faster) smaller cc'd bike ANY DAY of the week,than a larger,longer,heavier cc'd bike!!! As Smaller=More Fun!!! :) ~Peace~

[@jponz85]

Nah I'll stick to my zx10r. Jumped to that from my zx6r

[@robertsalyers1351]

Just like Riding a Woman Smaller is more Fun...LoL

[@JohnnyWooh]

Must be so much fun to race the lighter, more nimble machines compared the big scary liter bikes.

[@JasonYergin]

Awesome video!! Don't stop with these MC

[@Gamen4Bros]

I have that exact same akrapovic on my Ninja 400 KRT!!

[@angshumansarmah6626]

I'd like to see your track built Ninja 400 🤘

[@camerongeater5404]

Ok Ari. You got me. I've totally fallen for small race bikes.

[@authenticmax6350]

Don't even think that way.... you will understand once a bigger bike passes by you in a flash.

[@aerop.3030]

And then you pass them back in the corners and think of what a fool they look having to use a bigger bike to keep up.

[@authenticmax6350]

Well you'll only pass them in the corners if you are able to reach the corners sooner... duh...

[@evilnoobcube3818]

can you do a tutorial next on how to convince my mom to buy me that bike ?

[@funkymonkeylovin]

EviLNoob Cube Drop out of school and get a job.

[@CollinMac96]

Get a job and/or move out. #SIMPLE

[@RingRingRingBananaPhone]

sell the mountain

[@RumblestripDotNet]

That's CHEAP for a well-prepped race bike, I was fully expecting close to $20K for the full-on MotoAmerica spec bike.

[@norsefalconer]

Rumblestrip.NET I was thinking the same. Relative bargin, really.

[@AriH211]

Plus it's been developed and set up by a real pro, so there's value in that. Anyone can throw parts at a bike, but chassis setup is what's key and that takes experience to do right.

[@authenticmax6350]

You're out of your mind... MotoAmerica is not MotoGP...

[@williamdeimos2354]

You are correct MotoAmerica is not MotoGP.... but this is a MotoAmerica bike prepped by a professional costing you 20k, not a MotoGP bike costing millions. Not entirely sure what your point is.

[@authenticmax6350]

I meant to say that its a Junior Cup class... Rules specification don't allow you to go bananas on the mods so definitely the bikes will be way cheaper plus the fact that there are plenty of parts manufacturers and big price competition between parts manufacturers have made things a lot cheaper. Thanks.

[@raphaellacasse-linteau]

Since I will be racing in the canadian superbike championship next year and it's the same class than the liquimolly junior cup. I might pick one!

[@LunringNassar]

After hearing that price, a supersport just seems like the better choice. R6's, CBR600RR, Ninja 636.

[@neetones]

Excellent organization and presentation.

[@irvinrodriguez7199]

I'd love to get your opinion on how this compares to your track version of your RC 390.

[@juansantos5678]

It’s probably too close that they don’t think it’s in they’re best interest

[@FullSpeedBrasil]

Like! What are the tire sizes?

[@Alexander5R]

I have a RC390 and I dont like the stock Ninja 400, but this one looks very sweet. Congrats.

[@stoneblue1795]

That gold chain will make it go much faster.

[@rzu7120]

JP Stone Italian Ninja?

[@kingsambition2179]

JP Stone about 50hp extra

[@tngchinghwa]

i thought black is always faster?

[@stormtrooper9404]

C’mon... We all know that nothing adds more speed than stickers on the bodywork. Heck,its scientificaly proven that red ones even saves weight,while silly ones help reduce the aerodonamic drag.

[@PokeyCottons]

Yes, if you buy one of these, definitely change the plastics to red for max performance!

[@epichazyt6641]

I was thinking of buying Yamaha R3 until I see this.. Just which one should I choose? Both looks amazing as it is..

[@slickshit_at]

but where’s the blipper? And the oil cooler? Ahhh I forgot that iam the only one with those moods on my 400 😅. Still a great video guys. 🤙🏼

[@Bosephjones]

Ari - I know the front needs to be lowered slightly for the vortex clip ons to fit, but do you know if the rear was initially lowered to match when the front drop? I know the rear shock is adjustable, but Im looking into installing vortex clipons to my wife's 400, but its still on a stock rear shock and stock front suspension. I didnt know how much "too" much was when lowering this particular model. from what I've read it should only need to be dropped 5mm, but I'd hate for her to find any stability issues when shes out on the track.

[@3lionsbecks]

Please do a first ride on the new Honda CB300R. Would love to hear what you think of it as a beginner or city bike.

[@hanhtoobala7510]

What about the tyres for this bike? Is it the same size as the stock tyres?

[@imrin4059]

Did u make video how to change clutspring wish spring to charge cus my slip slot when shift hard

[@Mike-ul1xn]

I hope they sell kits for the brake and clutch mods

[@kumarmithilesh1886]

Hey Ari 👍, can we swap instrument cluster of two different bikes of same brand.? I believe you can answer it as you go into the depth of the bikes and their working and also have worked in a lot of bikes.

[@ZX10RArcher]

Great video Ari

[@connorrobert5348]

we need the 400's of the 90s to come back

[@pags1981]

The swingarm on that thing is nasty, wonder if a zx6r part would fit?

[@justinsmith8456]

I am trying to understand the chain and sprocket set up, i don't see anywhere online where Vortex makes a 415 sprocket set? Educate me please.

[@GETUPANDGO]

Pretty cool build, smaller bikes are so much fun

[@malcolmSC]

51hp at 10k RPM... and there's 2K more. That is nuts.

[@skewty]

No, there isn't more. He changed the power curve because he couldn't rev it out. Learn about the area under the graph.. You can trade hp for torque or visa versa.

[@exothermal.sprocket]

@@skewty Of course there is more. A custom cam profile isn't going to suddenly fall flat on it's face after the 10k limit, if the limit is removed. Increased compression ratio practically guarantees that. The math formula for horsepower just requires more revolutions per minute to increase power, everything else equal. If the heads can flow more air, they can make more power with faster engine speed.

[@dingoog1]

This over the new stock kiwi 600? Thoughts? It’s about the same price.

[@carmarusso3869]

The RPMs being limited to 10k has to be a big factor in power output. I would have liked to hear what the hp number is at 12.500 and further up.... just to know

[@arunpr93]

Plz make a video about RR 310 . TVS . Which have same BMW 310 engine .

[@joshuamcgarvey2712]

cant get enough of the ninja 400 #kawasexy400

[@Edward-ko9pn]

Did they leave the stock dunlop tires on or swap in better ones? I can't tell by looking at the video.

[@thomassylvestro9041]

Could you please do a video on trail braking, how and why

[@MrAnders1976]

It is a A2 bike.. An A2 bike has a power limit of 35kW = 47bhp and a power to weight limit of 0.2kW/0.268 bhp per kg, so if you want the full power of 47/48bhp you need a bike with a wet weight (full tank and oil) of 175kg. The Ninja 400 comes in at 168kg so the power limit is 44bhp.

[@user6.6.6.6]

Stock footpeg for racing??😅🤨

[@razor1uk610]

...How long until someone tries out fitting a H2 supercharger with intercooler/expanded plenum chamber running at a lower sc-rpm via an altered drive gearing..? ..of course it'd require atleast some heavily engineered custom designed side cover(s) assemblies to fit and take drive from the clutch input (assuming thats where the H2 powers it from).

[@scottsaylors1996]

This is sick

[@cyrvincentmontagiangan9709]

Gotta build mine soon

[@858415]

[@dandee28]

what is your height and weight? will I be too small at 5'8 140lbs for a yamaha r6 or a 600 cc in general??

[@fireoil]

So that vs the ktm rc 390 race, what do you think ?

[@garymanning8920]

What is your height and weight? Im 6 2 185. Im looking for a 400..

Where I can buy that belly pan for ninja 400

[@lynch7]

Any videos of this with sound from the bike? Harder to get excited when you can't hear it

[@calcou]

Nice bike. I'm just wondering how did they manage 310 lbs. The curb weight is 366 lbs. 56 lbs is a true dry diet with stock wheels... Anyone? I'm planning to change my old zr7. Can't make a choice between a new bike or a second hand with less displacement that I could turn into a little race bike with the money saved.

[@Tiagotaf]

And how much does it weight ?

[@boston05011]

Is this site still up and running

[@jonruby1755]

What kind of tires do u have on it?

[@FastMav347]

That tire sticker was driving me nuts

[@SpartanAirsofter98]

If you had ever been on track you would know they scrub off almost immediately. A good 60% of riders at my local race club dont bother taking them off.

[@rattletop]

Just curious - if you are going to instal vortex clipons, why not install it under the triple clamp? It is still high for a race bike, no?

[@A-FrameWedge]

Sun It might be breaking the rules in the class this bike races in.

[@TubesBadger]

Do you think that this bike is more capable than the R3 for Track build and use? I’m about to get one of them for track build . Opinions which one to take????

[@pacificexcursion5846]

400 for sure. More torque, horsepower, top-speed and lighter weight. It’s all around a better bike.

[@SkyAmbassdeur6500]

You should look at the zx150 kawasaki!

[@fire.dragon1976]

Any onboard video?!!!

[@Camps2630]

Is the 400 a good bike for someone new like myself as well being 6’2 250, or would I look silly.

[@robertsalyers1351]

You all ready look silly You would just look silly on a Bike if you buy one...LoL Just kidding !!

[@rahm7723]

I would love to see an un-limited rpm version. Maybe 15-17.000?

[@SlyFox454]

Where's the R3? I've only found a couple of vids about it. Is there a full review out yet? Also, of all the small bikes, which is your favorite to race with?

[@AriH211]

The R3 is parked, been too busy to work on it or race it. It's fun and works well, but the Ninja walks all over it. :( If I was going racing tomorrow I'd be all over one of these Ninjas.

[@nathanwiens108]

Probably needs some more balance of performance.

[@AriH211]

10,000 rpm, as mentioned in the vid. I rode this bike unrestricted later in the day. The fun factor went up substantially.

[@nathanwiens108]

Yeah, I hadn't gotten that far in the video :S I just feel for Yamaha and all the money spent in this class that became instantly invalidated by the release of this bike. We've got a A2 license arms race now. Which is great for riders, but is going to be painful for the racers for a couple of seasons until the R3 gets upped in displacement. The 390R was also a huge kick in the teeth from the discussions I've had with Ken Hill and others who coach these kids.

[@jamestownsend100]

Ari Henning Does that mean the Ninja is your favourite of all the race-prepared small bike’s you’ve ridden/built? Even better than the RC390, R3, and CBR300?

[@AleksAndrosik]

Why is the left hand grip so far out compared to throttle side?

It just looks that way because you have the switches for the start and to kill the motor on the right side.

Ok. I was really impressed with your ktm race bike since and I was more than stocked up when I saw you tuning the r3 in the Dyno and that pov on track. Still waiting for more vdos on that r3 as am having one myself. Yours reviews are awesome. Keep them coming. Love from India 😀✌🏻

When he said 50 something HP that's at the wheel. The 49hp version sold is about 44.5hp at the wheel I believe. Just watched a video on this.
