Thanks for the awesome 400X videos! I have had mine 2 days and am enjoying it. Ordered the 15T sprocket today and will follow along with your video to swap it.

Thanks for posting. For me the 15 swap is working out great - I would have been able to do it quicker if I had seen this video first. I think this will help other less experienced people like me.

No need to pull the axle. Just loosen up the adjusters to provide enough slack in the chain to remove the old sprocket and install the new one. Just did mine the other day. I like the gearing change, bike just seems more calm in each gear.

My name is Kevin. I live near Lake Erie in Southeastern Michigan. I’ve been following your videos and I’m very impressed and I wanna thank you for taking the extra effort. I had mentioned buying a 15 tooth sprocket didn’t know where to get one and I appreciate your interesting articles and I follow you now and subscribe to your channel.

Just got my 400x yesterday - I love the low-down chug of the original sprocket, but honestly I do more hwy than offroad so a 15T will work

Definitely going to try this. Not that I would ever ride a motorcycle on the Pellissippi International Speedway. Thanks for detailing the process and the results in a usable and easily understood format.

I bought 400 X scrambler Triumph should thank you. You’re half the reason I got one.

This is definitely on my list of things to do sooner than later. I did the same thing with my CBR500R and it worked very well. I’m very happy with my scrambler overall. My only gripes are the really poor headlight performance and the massively over-brightness of the instrument display at night. Looks like you live in a nice part of the world. 👍😃

Excellent video and audio. That engine and the gearing...beautiful. I did the same change on my first V-strom and will do it immediately when I get the Scrambler.

You live in a beautiful neighborhood Great video, I shall do the same on my Speed Twin

I love your videos. I just had my Scrambler delivered yesterday and I'm looking forward to modding it. I miss Tennessee tremendously with all the mountains and curvy roads. We hope to move back that way by the end of the year.

I was very interested in this as well but I put bigger knobbier tires on my bike and that helped tremendously with the short gearing, it still even with taller tires feels like it could have better gear ratio so I may go this route! Keep up the good work bud!

You know its funny how certain exits, interchanges, interstates have the same flavor whether its Tennessee or all the way down to Ocala Florida. Unless there is a major elevation change in view, they all look the same! The only clue is the names and numbers on the signs.

Great video, thanks for taking the time to make it.

Awesome test and review ride. Thanks!

I believe I may have to do this. Thanks for the great videos

I’m thinking of a triumph 400 test rode one last week nice little bike but I ride a gsxs 1000 with a map etc etc makes sense to buy the little bike to hold on to my license!!! Not sure I could handle the hp drop I’m torn tbh

What are the down sides of doing this? I’m a new rider and picked up my 400x a couple of days ago.

Thank you for this great fix for better top end performance! It's on my list of things to do. Question: can you make a recommendation of better foot pegs that will fit the 400x? Something wider and more dirt bike style...thank you!

Thank you for the video. And about the top speed? Was there any change?

Great video, thanks for sharing ! Did you lose any noticeable power or torque at low gears ?

Just ordered my 15 tooth sprocket. I was recently asked, why not use the 15 tooth from the Speed 400? Are those not available from Triumph? Also, what’s the tail bag you are using? I like how it connects to the bike. Thanks for the great videos! Keep them coming!

I just did this today and really like how it makes the bike feel so much more relaxed through all the gears. Especially on the open road at freeway speeds. Great video, I referred to it during the swap. I tried finding the bolt torque specs online but no luck...any idea where they can be found? Rear axle and front sprocket nut...

Does is solves the vibrations which annoyes post 7000rpm?

Thank you for this video

Great bike, great video! I'm also thinking about changing the sprocket. I've seen all of your 400X videos and I'm a little surprised that you seem to think the front brake is OK. I find the braking effect very poor and you have to use a lot of hand force. Are you thinking about it or do you perhaps have a solution?

Great video. Looks like a project is ahead. Curious about your flyscreen. What kind is it and does make much difference? Helmet roar? Thanks.

How does this affect the accuracy of the Speedometer ?

Does everything count correct after This? Feel like I heard something would count wrong when changing sprockets

You didn't turn off your ABS or Tration control.... The yellow lights would be permanently on if you did

Already ordered a 15 ( KTM 390) frond sprocket

This is exactly what I was looking for, thanks! Question, the link to purchase the sprocket shows a Duke 390, and my assumption is it is interchangeable, correct? I'll be ordering mine now. I tried ordering the Speed 400 sprocket but could not get confirmation from my Triumph parts dealer that the Speed sprocket would work, he said the spindles showed a different part number. I was going to order one anyway as the sprockets are inexpensive, but I am just going to order your recommended sprocket. Thanks again, this will really help on the long stretches of highway I'll be doing on my annual motocamping trip in a few weeks!

Interesting I will do this mod it would of been good if you had done a 0 to 60 mph Comparison before and after the change, Also in the video you didn't enable off road mode! Because the traction control light was coming on! Also when off road mode is set by holding down the button for 5 seconds you know it in the mode because a light is permantly on the dash when it is

Great video. I'll do this on my 400X (music is just a tad too loud)

Thanks for the video . Just got one for my self ! Which gps app do you use 🙏

also did this with mine still waiting on my kspeed accessories and exhaust tho

I don’t know why, but it bothers me that Triumph puts the chain on the wrong side.

Hey, Nice and useful video. Wow, I impressed with this idea and I am going to change on my bike as well. Is length of the chain sufficient or do we need add more links? What are the other sprocket option 16t? I really don't have idea on this.

So theoretically the mileage should also improve right?

Pode ser qualquer um dos pinhão que está no link, porque tem uns com encaixe diferente? Gostei muito do seu video

is the rubber cushion necessary and does the stock sprocket have one? I just ordered my sprocket as well as a slash cut tip exhaust from AJ cycles in NY.

What kind of phone mount do you use? The one that I have is centered (which is what I wanted) but it sticks up so high that it covers half the guage cluster in front of me.

hi, whats the torque settings on the sprocket? thanks

Is it ok to lift up on the sump guard ??

Why on earth is the chain on the same side as the muffler? All my other bikes are on the left side. Is this a Triumph thing?

what about a smaller rear spockt also

Does changing the sprocket void the warranty at all?

so if u do that, the speed won't be displayed correctly anymore?

Is that the rubber cushion sprocket?

Thanks for the video. But goddamn, chin cams make me nauseous. Maybe switch to a chest cam that isn't swiveling all over the place?

What happens if you also replace the rear sprocket?

of coarse you can; honda 500x had the same problem; a useless first gear !!

GPS speed or it's a waste of time watching ..

No torque wrench 😮
