2018-2023 Kawasaki Ninja 400 Throttle Tube Mod | Sportbike Track Gear

[@succafool9]

Ordered this and installed it in a matter of minutes. The difference in the motion in the video didn't seem substantial. In real life it made a lot of difference and makes the bike much more trackable. These videos have helped me so much in converting to a race 400. I try to use STG for every purchase possible. Thanks and keep up the awesome work!

[@sportbiketrackgear]

You are welcome! Thanks for watching, your business and the kind words. - Van

[@DanielKulka]

This is why I've ordered so many modifications for my kawasaki z400 2022. Because of the outstanding videos.

[@sportbiketrackgear]

Thank you for and happy to hear the videos have been helpful! - Van

[@Scott-sb1xi]

This is a great family owned store that is really into racing and sportbikes. I buy from them whenever possible.

[@sportbiketrackgear]

Thank you for watching and for your support. - Van

[@gbo4518]

I bought this tube off you guys and did the install last night. There was no difference in throttle throw from OEM. I even swapped them back and forth using tape and a caliper to measure the throw difference. I measured maybe 1-2mm at best if anything. Not sure why my result was different.

[@JeremyDN]

I think I can make a new tube at my work since I work with 3D printers. I can make this out of carbon fiber so it remains strong and I can modify that lobe to make the throw shorter if needed. Thank you for the videos. I’ve learned a lot about my bike and it’s transformed a lot over the last month. Wish YT allowed pictures to be posted.

[@sportbiketrackgear]

Sounds interesting, thanks for watching and good luck with your project. - Van

[@Farmerfrommishmi]

Hi, is it possible to make fibreglass race fairings using a 3D printer?

[@JamieS1992]

I did this with my R3 awhile ago its a nice mod mentally you think the bike is faster but its just the throttle tube

[@gronkgrunk]

Nice. I'm thinking of doing for my R3 as well. We're there any issues installing it, or was it a perfect fit?

[@JamieS1992]

it was a little hard for me getting the two cables connected to the new tube but maybe it was just me being a d head and had never changed a tube before but other then that it fit fine fit better on an R3 then it would a ninja 400

[@Maweeji]

I believe there's an throttle cable adjuster near the throttle for Ninja 400

[@sportbiketrackgear]

Yes there is a throttle cable adjuster on the Ninja 400. - Van

[@jgenova48]

Great video, but one quick question. I followed this but for my 2024 Z500 (I know the bikes may be slightly different but taking my chance) using a norton Motorsports throttle tube. After installing, I noticed that I lost some adjustability in the amount of slack in the throttle. At the loosest setting, my throttle has zero slack, and may be even in the negative slack range. Is it possible that my cable is too short?

[@sportbiketrackgear]

The cam on that tube is larger and you will lose some adjustment. After installing it make sure the throttle return is strong and that there is no binding. - Van

[@capt.crunch1276]

Will the R3 tube work on the 24 Ninja 500? I'm sure it will, but I'm just making sure

[@sportbiketrackgear]

I would expect it will but can not 100% confirm. - Van

[@reinaoffthewall7479]

i have a 2020 ninja 400 only 1800 miles, throttle stsrted sticking so i used this video for reference to disassemble throttle housing. put it all together and the throttle snaps back perfectly but there is no play. i tried making adjustments at the cable but its not giving me any freeplay what do i do?

[@sportbiketrackgear]

First let me say the throttle needs to be right otherwise the bike is not safe. All I can tell you is to try an follow these steps again and to double check your cable adjustments. Try to back them off a bunch to introduce a little play then adjust it out with the end result being just a bit. - Van

[@jaymarkmarbebe5865]

I did follow the instructions but sad my throttle won’t slack back it’s tight any model of rc throttle tube

[@sportbiketrackgear]

Perhaps Kawasaki updated the OEM throttle and this won't work on newer models??? It for sure worked on the 2018. You can check to see if they have updated the throttle by comparing the OEM part number from the 2018 to whatever model year you have. - Van

[@damonjohnson9345]

I noticed one guy mentioned this below, do you mind explaining how this tube is able to shorten the throw range without cutting off the higher end? I have a ninja 400 and the 1/4 turn is killing me on the open throttle upshifts. I'll take your word for it, but now I'm curious because I can't figure it out. Great videos, love the detail and thorough explanations.

[@sportbiketrackgear]

The cam on this tube is larger than the one of the stock Ninja 400 tube is. There is no reduction in full throttle, just a shorter turn to get to 100%. This is the cheapest way to improve the throttle. The most effective is the Motion Pro Rev2 Throttle kit for this bike. Here is a link to the video install for that on our site: www.sportbiketrackgear.com/motion-pro-rev2-throttle-kit-kawasaki-ninja-400-2018/#pv__tabs - Van

[@UKGeneralCOD]

Broke my grip on my moped ordered the part gonna try change it tomorrow it just keeps spinning so hoping it's just the grip which I've order a whole new grip and tube hopefully works thanks for the video hope it's similar to a moped 😅

[@sportbiketrackgear]

The process will be super similar. - Van

[@RolandoGarciaGonzalez]

What grips are you using ?

[@sportbiketrackgear]

Driven D-Axis Grips www.sportbiketrackgear.com/driven-d-axis-grips/

[@Crazy.....808]

Hello I have 2022 ninja 400 abs can you give me the link to the exact one I need. Also I guess I would need new handle Grips what are good ones to get. My 400 is the blue one. Thanks

[@sportbiketrackgear]

To the best of my knowledge this still fits the 400. Motion Pro Yamaha YZF-R6 03-05 Nylon Throttle Sleeve www.sportbiketrackgear.com/motion-pro-yamaha-yzf-r6-03-05-nylon-throttle-sleeve/

[@deandee8082]

this mod is a MUST for getting off the apex on a gixxer, that 7/8 garb just doesn't cut it unless you want to look like a ham fister from hale... my grips are always naked ..

[@sportbiketrackgear]

For sure this makes a difference. - Van

[@Dahockeydad]

Love your videos!!! They have helped me tinker on my bike with no experience. I was wondering if you could help with a question? I'm thinking of taking my ninja 400 on a 300-500mile trip all highway. Would that be to much on the 400 cruising at 8000-9000RPM's. I will be riding with friends on bigger bikes. I just want to make sure I can keep up if they are going 80-90mph? Again love the videos keep up the great work.

[@frankiek.1261]

You will be fine buddy. :)

[@sportbiketrackgear]

You are good to go my man, ride it as hard as you need to. Our Ninja 400 spends all of it's time on track with Max Van at 100% throttle. - Van

[@hudsondelay7713]

I attempted this mod on my 2023 ninja 400 and my grips are sticking out more than the throttle tube. If I push the grip onto the tube any further it will touch the throttle housing and rub. My bar ends aren’t touching the over hang but it’s a little annoying to know that they aren’t on perfect. Did I do something wrong?

[@sportbiketrackgear]

Not sure which grips you are using but we used the Driven grips with this install. Some grips will stretch when you put them on and need to be compressed a bit. To do this slide the grip up to the throttle housing (make sure you do not have the rubber grip dragging on the housing). Once you have done that hold the grip at the throttle end then push the bar end side towards the throttle. If the grip was stretched this should shorten it back to its original length. - Van

[@maxvaquilar5305]

hi i don’t understand why my throttle won’t snap back?

[@sportbiketrackgear]

You need to double check your work. It is either installed or adjusted incorrectly. Do not ride the bike until you have this sorted out. - Van

[@tomss4098]

does the ninja 250 2015 have the guide thingy as shown in 4:24 ?

[@sportbiketrackgear]

I have not had a throttle apart on that model bike. - Van

[@Fee.1]

What flashlight are you using halfway through? Milwaukee?

[@sportbiketrackgear]

Some no name deal I picked up at the hardware store. - Van

[@boniwaiss]

thank you so much for all of your videos¡ i watch them all

[@xevenex]

hey Brian, I know it's listed as 'out of stock' in your website but can you please do a Motion Pro REV2 Throttle Kit install on the Ninja 400 when you get the chance to? I'm really interested in getting it and I wanna know if I need to get any other parts such as the starter switch etc to complete the install for street riding. thanks in advance!

[@sportbiketrackgear]

We will get to this project at some point down the road, still a lot of other parts to get bolted on the Ninja 400. - Van

[@xevenex]

ok great! no rush, Brian. I'll be getting the Motion Pro Rev2 throttle kit with the new starter switch, and the Woodcraft clip-ons with the weighted bar-ends sometime at the end of the year or early next year. I normally do my homework weeks or even months before I purchase. you do a lot of the fantastic work for the most of us. keep it going brother! 😊

[@brzo]

would this be possible on a Ninja 300?

[@sportbiketrackgear]

I do not believe this fits that model. - Van

[@markwalker6692]

Hey tried to get the bar end off but it is being extremely hard to get off on both sides and I'm a strong guy. Is this normal? Still can't even get it off.

[@sportbiketrackgear]

As I remember it that OEM bar end was on there pretty tight, may have used some thread locker from the factory as well. Make sure you are using a quality Allen Wrench and get after it. - Van

[@markwalker6692]

@@sportbiketrackgear Got it, thanks! Gonna get some of those driven racing grips now!

[@Strict-Sandwich]

Could i just place the grips on beforehand?

[@sportbiketrackgear]

Not if you want them to be lined up properly. - Van

[@Strict-Sandwich]

@@sportbiketrackgear Thanks for the reply, i'll do it the correct way!

[@27300man]

I just did this install but I just can’t seem the get the throttle to snap back like that. It returns slowly. I even trimmed some plastic. Any suggestions? Is it dangerous to leave it the way it is?

[@sportbiketrackgear]

If you can not get the throttle to return properly then take it out. We did this on a 2018 Ninja 400 using the Motion Pro tube for the bike we mentioned and did not have any issues. Not sure if Kawasaki has changed the throttle after 18 or not. We have several other Ninja 400's here but they are all race bikes now. - Van

[@partyparty6216]

Hello sir. Can i ask? Why is my throttle moving with the switch when i turn my throttle. Pls help. 😔

[@sportbiketrackgear]

Check to make sure you have the dowel pin for the throttle housing lined up with the hole in the clip on. This is there to hold the throttle housing in place and prevent the issue you are describing. - Van

[@geofftentwo]

Thank you for all the videos! There is a big gap between my Driven V2 bar ends and the grips. Is it possible to move the throttle housing/tube outwards? I think I need to drill a new locating button hole in the handlebar??

[@sportbiketrackgear]

What is the year, make and model of your bike? - Van

[@geofftentwo]

@@sportbiketrackgear Sorry! It's a 2018 Ninja 400.

[@sportbiketrackgear]

@@geofftentwo I assume you used the Driven Bar End Adapter M8 to M6 Reducer DBEW-ADP8 to install the bar ends on your OEM bars? If this is the case the gap on the throttle side is normal with OEM throttle and grips (there needs to be a gap between the rubber grip and bar end to prevent the throttle from sticking). Is the end of the grip all the way to the end of the throttle tube? If it is not that can make the gap look big. - Van

[@geofftentwo]

@@sportbiketrackgear Yes, used the M8 adapter. The grip is in original position at the end of the throttle tube. I suppose I could move the grip so it extends off the end of the throttle tube, but then there with be a gap on the other side.

[@sportbiketrackgear]

@@geofftentwo You might need to replace the grips to get it closer to the end of the tube. The OEM throttle tube has a rib on it that line up with the OEM grips. I would not recommend drilling a new hole for the throttle housing. - Van

[@danielespina1749]

help! which motorcycle you recommend the r3 or the ninja 400, I am from Guatemala in my country the ninja 400 is worth 1500 dollars more than the r3, I love both and I do not know what to buy, is much the difference between them? I love your channel thanks for the tips !! 🙂

[@mynigga1337]

Daniel Espina ninja 400

[@sportbiketrackgear]

Daniel the R3 is one hell of a motorcycle my brother. $1500 is a lot of money, I would go for the R3. My Son Max is riding our R3 on the track now (there are also tons of adults riding them now as well) and he is having fun dragging knee all over the place. - Brian Van

[@danielespina1749]

Sportbike Track Gear thank you very much bro, greetings to you and your son from Guatemala

[@letsride4496]

I installed a r6 throttle tube on my r3 but the throttle would snap back once the bars where turn left how dfo you fix binding

[@sportbiketrackgear]

It sounds like the cables are too tight and need to be adjusted properly. I did not do an throttle tube install on the R3, only on the 400 so I am not 100% sure it fits the R3. Try loosening up the throttle cable adjuster (shorten the cable) and see if that helps. If that does not make a difference then you will need to tear the throttle down and make sure you have the tube installed properly. - Van

[@keepittwisted3805]

Does this work on a 2014 ninja 650?

[@sportbiketrackgear]

I am not familiar with that model so I would not be able to say. If the OEM part number is the same of the throttle tube from the Ninja 400 to the 650 there is a strong chance it will work on that model. - Van

[@adriancedeno8788]

I have a 2019 Kawasaki ninja zx6r and looking to do this mod but i don’t know what will work

[@FuturisticViper]

what's the grip glue that you are using in this video?

[@sportbiketrackgear]

That is Renthal Grip Glue, we keep this in stock here at the shop. Here is a link to it on our site: www.sportbiketrackgear.com/renthal-grip-glue/ - Brian Van

[@ruelpalma9724]

Hi again brian can you pls send me the discription of the throttle tube that can fit to my r3. I heard that the r6 throttle tube fit to a r3 is that correct. Pls send me a link pls thanks

[@BleedOrange420]

Hey gang! You guys are soooooo great. Everything I need. I had all my parts already, but I can't wait to spend some $$$ with ya to show appreciation. Meanwhile...I'm your typically broke racer. This is cheaper than the motion pro kit - do you have a feeling whether that is worth the extra money when one is on a budget? Thanks!

[@bananaman3237]

The 03/05 R6 tube is only fractionally bigger than the stock Ninja (36mm). The 06 on R6 is 41mm diameter which will give you 20% less travel. The mod in the video is a waste of time.

[@sportbiketrackgear]

The fact you can't spell "which" makes your comment a waste of time. - Van

[@bananaman3237]

Why not check the details, then offer some usable advice.

[@prettyfarfetchd1838]

ive been thinking about doing this for my 2019 ninja 400 but I am still a little hesitant on how well it fits. Since you have had this mod on for a while, can you give some insight on how its been? Are there any more official tube mods for it rather than using an r6 throttle tube?

[@sportbiketrackgear]

This mod is not bad, the best way to get a quick turn throttle is to install the Motion Pro Rev2 Throttle. We have that on our Ninja now and prefer this to the R6 tube mod. Here is a link to the video install for this on our site: www.sportbiketrackgear.com/motion-pro-rev2-throttle-kit-kawasaki-ninja-400-2018/#pv__tabs - Van

[@MrBoomtheroom]

any idea what tubes fit a s1000rr?

[@sportbiketrackgear]

I am not sure there is one that fits this bike. Jimmy is looking into a quick turn for his S1000RR now. We will shoot a video if he finds one. - Van

[@robertfancher7381]

What size are the bars? 7/8 or 1 inch? I'm thinking about doing this mod to a versys x 300

[@sportbiketrackgear]

This throttle tube is for 7/8" bars. - Van

[@spotthedogg]

That's not the throttle tube you want, you want the genuine Yamaha R6 tube for the next generation 9'06-'08 I think) it will give you 1/6 turn where that one may be 1/5 turn

[@spotthedogg]

YAMAHA 2C0-26240-00-00 and I am pretty sure Motion Pro doesn't offer an equivalent, they didn't when I last researched.

[@sportbiketrackgear]

On the Ninja 400 Forum someone mentions attempting to install that tube and running into issues with the return of the throttle. We have the late model R6 tube on the way to install in the R3 now and will post up the results once we complete the install.

[@sportbiketrackgear]

They just released one a couple weeks ago, on back order now with the suppliers and waiting on the one we ordered to install in the R3. - Van

[@spotthedogg]

On my application I did need to Dremel a bit of plastic from the housing so it’d fit and not drag. My bike is a Honda VTR250 using a CBR1000RR throttle housing BTW. Great video, lots of detail..

[@InfamousInternetVillainJackSix]

STG's first comment is correct. While the 05 R6 tube has a more aggressive twist, it also requires you to remove your throttle return cable. Whereas the 06 R6 tube allows you to keep the return cable, at a slightly less aggressive twist. I made a video on this as well, about 2.5 weeks before this video was posted.

[@MoodSwingZX]

I bought R6 used for 5$ with shipping for my gixxer.

[@sportbiketrackgear]

Pretty sure that is a common mod on the GIXXER. - Van

[@emudshit]

seems like only a 7-10% reduction in the turn :/ is there any others tubes that would fit that reduce the turn by at least 20% ?

[@sportbiketrackgear]

We have the late model R6 tube on order now to install in the R3. This tube has a little shorter throw than the one we installed in the 400. I read a post on the Ninja 400 forum that claimed the late model R6 tube could not be installed in the Ninja 400. When we receive the tube on order I will try to install it on the 400 and see if this is correct. For now the 03-05 R6 tube fits and I had no issues with throttle cable adjustment and return. Very important that your throttle works correctly, no binding and a snappy return. - Van

[@emudshit]

Sportbike Track Gear I think the throttle tube of the late r6 fits the 03 r6 so I don't see why it wouldn't work, is the late r6 throttle tube have less of a rotation than the 03 r6 ?

[@spotthedogg]

emudshit it’s a noticeably larger diameter reel, so that’s where the limitation is in some stock housings.

[@sportbiketrackgear]

You are correct and thanks for helping out. When I did this video I wanted to be real careful to make sure I was able to get this done without modifying the throttle housing and the end result was perfect. Nothing worse than a throttle that does not return strong or sticks IMO. - Van

[@gronkgrunk]

Good tip.

[@sweetlou6539]

Gopro fpv?

Can you show how to replace air filter of ninja 400? Thank you :)

[@skewty]

Wouldn't this mod just amount to not ever getting 100% throttle? Instead of the OEM 0-100%, now you have 0-85%. Awesome; not.

[@sportbiketrackgear]

No this mod reduces the distance you have to rotate the throttle tube in order to reach 100% or wide open throttle. - Van

[@nirmargolis]

hey, does this tube different from R6 OEM throttle tube?

[@sportbiketrackgear]

No the Motion Pro is designed to be an OEM replacement for the 03-05 Yamaha R6. - Van
