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.

[@user-sx5lz9zv4q]

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.

[@cputeq007]

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

[@421Rider]

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.

[@firehawkmph]

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.

[@ANIK5261]

Just did this mod yesterday (ofc this did helped me a lot) 😅 And yeah it feels so calm gearing now ;) Rpms have definitely dropped by 500 for first couple of gears. Tbh I used 15t sprocket from bajaj Dominar 400 also changed front break pad from bajaj dominor 400 (same part used by ktm 390 )

[@itskyb]

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.

[@RidgeRoamer]

@kevinlayne6946 Thanks Kevin! I appreciate the kind words and I appreciate you watching and subscribing!

[@detch5307]

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.

[@alanhayward6719]

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

[@nathandalleave252]

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!

[@RidgeRoamer]

Thanks! What tires did you go with?

[@knackeredrovers]

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. 👍😃

[@Fr99763]

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

[@udmbfckx2916]

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.

[@billesbacon]

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

[@billesbacon]

I use my Scrambler to deliver my bacon to Chefs in Lower Alabama

[@mrtyko]

Thank you for this video

[@sandiegophotographer]

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!

[@user-ln4tq5vp2l]

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

[@lexico69]

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

[@brenolicht]

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

[@johntoth9679]

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...

[@kennneee1]

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

[@RidgeRoamer]

@kennneee1 the flyscreen is just a cheap universal one off ebay. It is pretty short and doesn't seem to do much at all.

[@martynhurst3609]

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

[@nikoszaxos8942]

Already ordered a 15 ( KTM 390) frond sprocket

[@johntoth9679]

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!

[@johntoth9679]

Haha never mind, just watched the end of the video where you discuss the interchanability with the Duke 390! Thanks again

[@remarkableflooty7476]

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?

[@longjonwhite]

Get the brake pads for the Speed 400, they are better, (sintered).

[@georgedrampas6407]

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

[@RidgeRoamer]

@georgedrampas6407 Congrats! Google maps on road, Gaia for off road

[@lh5005]

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

[@leeinwis]

Way too loud, ouch ..have headphones on.

[@tangysquid]

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!

[@RidgeRoamer]

Thanks, lots of other 400X content on my channel! The 15T from Triumph is currently on backorder, which is why I went with the JT Sprocket. The tail bag is Triumph, but not sure what it's really designed for. Video about it here: kzbin.info/www/bejne/f4KsYZeciL1-d80

[@tangysquid]

@@RidgeRoamerthanks for this video! I ordered the 15 tooth sprocket you recommended and put it on last night. Works great! Makes the lower gears behave much better. Great video!

[@ANIK5261]

You can always use one from ktm 390 bike

[@venkat273]

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.

[@RidgeRoamer]

@venkat273 Thanks, no change in chain needed, other than adjustment. Not sure about going to 16T... might be too much

[@venkat273]

Thanks@@RidgeRoamer, Got it

[@AnonYmous-gi8wf]

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.

[@RidgeRoamer]

@AnonYmous-gi8wf I don't use a phone mount. What's on the bars is a Chigee AIO-5. See description for link to their page. Awesome!

[@definiteIynotkenji]

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

[@sergionemeth4920]

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

[@stumpytkd1774]

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

[@chefjoel68]

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.

[@RidgeRoamer]

@chefjoel68 the rubber is just a vibration and noise dampener

[@PBKB]

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

[@jeeperHK]

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?

[@sauledwards5611]

How does this affect the accuracy of the Speedometer ?

[@RidgeRoamer]

@@sauledwards5611 no change.

[@gopal.kalpande]

Does is solves the vibrations which annoyes post 7000rpm?

[@maxbelho]

So theoretically the mileage should also improve right?

[@carloscarvalho631]

Does changing the sprocket void the warranty at all?

[@RidgeRoamer]

Only if you mess something up while doing it.

[@popcorngJG]

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?

[@RidgeRoamer]

@@popcorngJG Just on the 400s (unless you count bikes that have split dual exhaust). No idea why they did that

[@IsaPorterMusic]

Is that the rubber cushion sprocket?

[@RidgeRoamer]

@IsaPorterMusic it's available with or without. Mine has the rubber cushion.

[@vnm_8945]

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

[@RidgeRoamer]

@vnm_8945 has no impact on speedometer. Speedometer is off from the factory.

[@vnm_8945]

@@RidgeRoamer oh, ok, thanks. :))

[@elwood62]

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

[@popcorngJG]

Exactly!!!! The weight of the chain and muffler should be opposite of each other

[@farzinbi]

what about a smaller rear spockt also

[@RidgeRoamer]

@farzinbi definitely an option... I am happy with this setup though. I think much taller and you would start to lose the low end grunt.

[@popcorngJG]

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

[@RidgeRoamer]

@popcorngJG yeah, I missed... thought I had it off, but noticed quickly that it was not

[@anandlakkaraju6825]

What happens if you also replace the rear sprocket?

[@RidgeRoamer]

@anandlakkaraju6825 it changes the gear ratio again... up or down depending on how many teeth rear sprocket.

[@anandlakkaraju6825]

@@RidgeRoamer so it will go back to its original behavior then

[@anandlakkaraju6825]

@@RidgeRoamer one last thing - does this change help reduce vibes at 90 mph . In your video I couldn't get a clear view of your mirrors vibrating. Hence asking 😁

[@RidgeRoamer]

@anandlakkaraju6825 it lowers engine rpms at any given speed, so yes, does reduce vibes too. But at 90, it still won't be smooth

[@longjonwhite]

Dude, this ain’t really a 90mph bike. If you want that, you need to get something bigger.

[@leeinwis]

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

[@RidgeRoamer]

@@leeinwis yup. It's in there...

[@longjonwhite]

Yep, I saw that, he also said, “Indicated speed, vs actual speed”. more than once, , , did you watch a different video?
