KTM 390 Adventure Gets Front Sprocket From Duke 250: Low End Issue Fixed
Вставка
- Опубліковано 10 бер 2020
- In the last video on my KTM 390 Adventure or KTM 390 ADV, if you prefer calling it that, I told you about a quick fix for the terrible low end - just swap out the front 15 tooth sprocket for a 14 tooth sprocket from the KTM Duke 250.
Not only does this mod cost almost nothing - Rs 250 for the sprocket - it improves the low speed rideability of the bike immensely.
Even if I take my hand off the throttle in the first gear, the bike keeps chugging along at 9 kmph, without stalling.
The bike also crosses speed breakers with ease in the second gear at low speeds now.
So, city rideability has definitely improved.
What has taken a bit of a hit is the highway fuel economy. Because now this engine is spinning faster to maintain the same speeds as the stock bike, I noticed a 10 per cent drop in the highway mileage.
I rode some 220 km yesterday - a very fast highway ride where we were averaging some 120-130 kmph for the most part, with occasional bursts upto 160 kmph, the motorcycle returned 27 kmpl. Which again is not bad at all. The stock bike I believe would have returned close to 29-30 kmpl at those speeds.
I am sure due to the shorter gearing, the city fuel economy will go up a bit though.
And for those who think we will lose out on a lot of top end, the bike still managed to hit 166 kmph without much of an effort. That's plenty for a person like me, at least.
My idea of the gearing on this bike is, if it can do 140 kmph all day and has another 20 kmph to overtake on the highway, I am okay with that.
I'll chose better city ability over outright top speed any day of the week.
What do you guys think? Let me know in the comments below.

As always, thank you for giving me your time. I hope you have a nice day. - Авто та транспорт
What am understanding from Abhinav's perspective is he can't digest the fact "itni assani se solve hogya🧐, vo bhi itna jaldi" 🤣🤣. Love your work brother, and understand how much efforts and research goes into finding a perfect mod and getting it done. Keep up 💪🏻💪🏻😎😎 we are following you.
Hahahhahaha
@@abhinavbhatt sir i wish to put a full system freeflow exhaust on my continental gt650, which is aesthatical and minimally performance enhanching too, i did consider the ssmto 2into1 u have one your int650 but i wish to have one custom made to my liking. if there is someone you know that could help me achieve this please do help me sir.. thank you.
SS Moto is making a 2x2 full system as well. Should be with me soon for testing.
@@abhinavbhatt does it give as much confidence and stock interceptor 650 at incline slopes......
Yeah.
Awesome content. The only channel which gives QUALITY CONTENT,
looking forward for R15 update.
I'll start work on the engine map of the R15 soon. Maybe Sunday.
@@abhinavbhatt WAITING
I love your blogs. No drama, no suspense, no show off. Waiting for long time for such videos.
✌
Very informative and should be super helpful- and thanks for not adding any stupid music in the background and keeping it clean!
I would say one of the best content you and DCV is making. It means no nonsense in the entire vlog, only knowledge, research and your efforts Abhinav bro. Every time I watch your videos, I will get the only new knowledge from them and the small change that you did in your KTM 390 ADV is simply amazing. You solved a big prob in 195 INR only.
I just wish you have to check the top speed real soon with this new sprocket like DCV and man I like your nd DCV's videos alot. Also love to watch you both together.
Thank you.
The only youtube channel where we get something interesting and experimental things
Thank you for great videos man. I'm searching for new videos about this bike every day, while I'm waiting to get my own delivered in the beginning of may.
But, that might be a problem because of the Corona quarantine all over the world. It affect the production and everything else. So I just hope the summer wont pass away before I get it.
I hope you get your bike soon, but realistically, coronavirus is going to stay around for a long time. First and foremost, stay safe and healthy. There will be more summers to ride. Cheers
I've ran my first set of chain and sprocket out and I'm looking to change the final gearing on my 390 Duke as well. This was super helpful, thank you so much :)
Well I am also planning on that can you share your experience will it increase accelartion and lower top speed.?
I like the way you review. No music no fade outs. Just facts. Kudos
Thanks
Hi love your channel and the information, a no nonsense, concise breakdown everytime. Appreciate it.
Thanks
Good experiment, useful for several KTM 390 Advantur riders
Thanks
Gonna do it next! Thank you for the info bro :)
Really love the way you put things out.
Keep up the good work
🙏
Very informative video bud.. I like the way you do the analysis.. keep the osmness flowing..👍
Thank you, Ritesh :)
Pure quality content❤
To the point❤
Hi Abhinav, You are the best person to ask this question:
Which one do you suggest for the low end engine knocking issue?
The front 14 teeth 250duke's front sprocket or the 47 teeth rear sprocket from racecustoms?
Which modification do you advice in terms of overall performance?
Finnally a sensible vlogger in town
Commendable English Abhinav Bhai!
Angrez Chale gaye aapko chor gaye. Just Joking buddy!
Your vlogs are amazing & insightful. Loved your collection! Hope I add the 390 Adv to my Garage soon! All the Best with your Channel! Stat Safe Stay Healthy Stay Indoors!
Great video. Very informative. I ride daily on this route and like you I also don't understand the logic of 50 kph speed limit on such a wide open road. Anyway looking forward to further mods in your KTM.
Thanks.
Thanks for making this videos Abhinav!!
Am going this weekend to change the front sprocket on my Duke 390...
Will let you know Once am done.
Keep up the good work bro!! 🥂🤟
Thanks, buddy. I hope you like the new gearing.
Abhinav Bhatt loved it! You are right, cruising at 140 with another 20 kmph in reserve for overtakes is good enough on Indian roads, as long as you enjoy the low end in city.
Tell me also about it bhai I'll wait my ig - adnanjsved__
Did you change?
Yeah that second gear thing happened with me many a times.. You are right.
Great video!👍🏽There is another way to solve this issue which I did on my Duke 390 2015 model. Changed the rear sprocket to that of Duke 250. This increased the top end a bit but reduced the torque. Stock A/F ratio on this is insufficient to produce enough torque to drive a larger rear sprocket at low RPMs. This issue can be solved in two ways, increase torque by reducing front sprocket size or decrease torque by reducing rear sprocket size. Both work well. First one, what you have done here I felt gives a more aggressive change and is good for offroading. The second one seemed better for highway rides as it smoothened the torque curve throughout the rev range..
Hey Abhinav , before the 1000 kms are crossed was there any rev limiter that stops the engine from revving harder and letting the bike go on a top speed. I did apx 120 kms yesterday from delhi to karnal and felt that the bike was being pushed back and not revving freely.
Is it supposed to not freely rev to 10000 rpm even if the shift light settings are not enabled before crossing 1000 kms. I felt like it was only smooth till 80 to 90 kmph and not so smooth beyond that point.
Discussed this retrofit with dealer today! Good to know it works well. Is that a dead dog in the road at 1:05?
What is effect on acceleration n fuel economy with 14 T sprocket. ??
As u mentioned in ur earlier video does this change give error in speedometer ??
A gentleman from Delhi. Rare breed. I know this cause I’m from Delhi as well😂👍 nice content. You seem to follow the KISS principle... for those who don’t know, it’s Keep It Short n Simple✌️👍 keep up the good work Abhinav!
Thanks, Harkirat :)

Have u test ridden
The new 390 Adv's with adjustable front and back susp?
Would love to hear ur opinion bout those.
If incase they are now better for city / road highway touring
Can you tell me what was done exactly to reduce the windscreen shaking/vibration at low speed please.
My pulsar RS200 also have same issue my bike has 14 T spocket at the front.
Im only city rider im thinking to shift 13T which was present at apache rtr 200 4v in front.
Because of pulsar rs200 need frequently gear shifting in city which is annoying.
Thank you soo much big brother 😍 you gave my problem solved.
Most welcome.
Top notch content. 👍
Could you please share some insights on INT 650, specifically with regards to the performance due to shorter front sprocket. I am planning to buy that, please help me. Thanks!
Do take a look at my last video. It is on my Interceptor 650 with a smaller sprocket and performance.
Does this change in the sprocket give better mileage? What is the mileage you get in the city?
I wonder how this low end problem suddenly came up now ? I mean, this engine was always there with us in the form of 390 duke and KTM says it's not been changed at all for the 390 adventure. And if this problem has surfaced due to making the engine BS6 compliant, then does 2020 BS6 390 Duke also has the same low end issue ?
Didn't this effect the ABS and electronics? One of the reasons I want to change from the Kawasaki X300 is that KTM is lower revving and doesn't scream when accelerating, I must admit I didn't notice the problem with the revs at low speed on my demo ride. I have always had large capacity bikes up until the Kawasaki and I don't miss the power and speed, just hate the high revs.
I just changed my engine oil from motul to liqui moly street race 10w-50. Just wanted to know if dats ok to do? Because it’s a new bike 5 months old and m scared. I own duke 250 bs6.
Will b waiting for your reply..
Hi So did you get the front sprocket from showroom or you had to buy the whole front and rear, bcz here in my near showroom I asked for the same they denied for single piece.
Hey Abhinav! Love your videos alot!
Currently i have a RE Thunderbird 500 i wanted to have engine modifications done to improve its performance can you suggest some and a good aftermarket exhaust!
Thank you so much for your videos they are alot informative!
Hi. See if AEW or Red Rooster make for the 500. Also check if Powertronic makes a piggyback ECU for it.
Thank you so much!
It's a good info on the solution. I believe the mileage will reduce as per the drive train change to lower radius front sprocket should not matter much. Top end will definitely reduce. Let us know please. Nice and very good info 👍
Hi Abhinav. Did u get the sprocket change from the service centre. Please advise.
Super video. In your video, you also said that you have a RE 650. How would you compare the performance/ease of use of the two RE 650 and KTM Adv 390?
KTM is the more fun bike but less refined in comparison to the Interceptor. Both are easy to ride.
@@abhinavbhatt oh wow. RE engine more refined than KTM adv 390? Didn't expect that. That makes my super meteor vs adv 390 decision even more harder. :(
Hey abhinav! Great video. Can you please tell me where you got the standalone 14t front sprocket from?
Hi. It is from the Duke 250. Available at the KTM service centres.
Wonderful vlog Abhinav. I just have a small question...why does the 390 have an unstable idle?
Hi. I'm not too sure.
Amazing and crisp content. You’ve offered a simple fix for a nagging problem that almost all vloggers have mentioned. Did you do the mod at the KTM service centre itself?
Yeah. At the KTM service centre.
Abhinav Bhatt brilliant . Thank you for the prompt response . I was holding off the booking because of this particular issue but now I’ll go for it .
That red bus sounds pretty good
Hahahahhahaha
Hi Abhinav, I m planning to buy a new bike next month, between Duke 390 and Ninja 300 which one will u suggest
Hy Abhinav! Thank you man for just pulling out the solution of low end question! But I want to know does this affect on mileage of bike? If not for sure going to this change.
I don't think it hits the economy much.
Good job. I rode it on the highway and I was okay with it. But off-road I think this gearing could help a lot. What do you think about instead putting a larger sprocket on the back? And if it will be as cheap and direct?
PS: what's your vlogging setup? The voice is very clear!
The rear sprocket will cost 10 times at least. I got one made out of stainless steel and it was for Rs 2,500. Back then I did not know that the Duke 250 sprocket would fit. Both do the same job.
I use a Hero 7 with an external mic. Some Rs 350 generic from Amazon.
@@abhinavbhatt you're lucky with the generic mic. I had too many issues. Can you share a link? How did you tuck in the wiring?
I have the same SPIDI gloves , for how much n from where did u bought them ?
Thanks brother for the update !
Most welcome.
How did you overcome the front headlight rattling issue?
Beautiful roads of Delhi. Just booked my adv 390. Love from B'lore
sir where can i buy the front sproket??any online store
Can we fix the same
issue with old Duke 390
This is now in my to-do list for this week . Hope this fixes my bike bitchy mood on low ends. 🙏🙏
Let me know how it goes.
Hello, where should i get this done from? KTM showroom itself?
Also, does it affect the quick shifter in any way?
Thanks in advance.
Hi. You can get it done at the service centre. Shouldn't affect the quick shifter.
Hey bro, Im also facing the same issue. Is it safe to replace the sprocket? And will it violate the warranty?
What about d engine heating problem , yes dey have provided 2 fans but warm air from d fans directly hits our legs which will fried ur legs , dis is wat I have heard and dis is d only thing which is stopping me to buy dis wonderfull bike , pls suggest and give ur honest review abt d heating problems waiting for ur reply thanks
Thanks for the update video, very informative.....is there a way to save the abs settings so that it doesnt switch on when the bike stalls or just want to load my settings
ABS stays the way you left it. It is the traction control that resets every time you switch the bike off and then start it. There is no way to fix that right now. I am in talks with someone to come up with a solution. Might take time. Will update when I have something to share along these lines.
@@abhinavbhatt oh I got them mixed up ...heard there is something called the ktm dongle which basically saves your settings ..idk if it is available for 390adv.
@@RajeshZmoke I don't think it is available for the 390 yet.
What about of roads ? Did it perform better?
Hey Abhinav. Just came across your channel. Your work is really good! Good stuff! Can you please tell which mic you use for your GoPro? Please add link in the description if you got it online. If you got it offline, please provide the details of the shop. Thank you!

Abhinav Bhatt thank you so much bro. All the best for your channel! 🙂
Where did you get that part? KTM seems not to have it in theirs catalog.
@ssmoto "full system exhaust" your up guys! Show us something amazing.
I'm after his life to build me a high slung full system.
@@abhinavbhatt can't wait, get a mix between the hypermotard and the Africa twin. 😍
@@angrybird29 Although for touring, a full system is absolute overkill and the sound will get annoying too.
@@abhinavbhatt sir , I was thinking of one more experiment , as u love doing modification , You can remove the catlic converter on and join a band pipe to stock exhaust it will reduce the 5-6 kg weight and might be won't affect the engine as well.
@@ABXPLORER I don't want to do that. No cutting etc. I'll only put a slip on or a full system.
i agree with all the comment below. ABhinav can give a different perspective from a rider and also a reviewer. i hope he's R15M Project finish soon
I hope so too, brother. Tomorrow will go to the customs to check on the parts.
and also what about the full system exhaust any updates ?
Glad to know that there aren't any speedo errors. Before I do the sprocket change, can you let me know what rpm the engine does at 100 and 120 kmph in 6th gear? Normally it is 6000rpm at 100 kmph and 7000+ at 120kmph.
I'll check this Sunday. If I remember correct, it was either 500 or 1000 rpm extra. But I am not too certain right now. I'll do a comprehensive test soon.
What is the benefit in terms of rpm band?
Torque peaks 1000rpm early?
Plan to change the rear sprocket?
Yes. And yes.
Abhinav, i have a question for you. Will it be problematic if we keep switching between 14T sprocket and 15T sprocket.? Will that affect the engine.?
No. Shouldn't be an issue.
That speed limit is for Car and LMV not for bikes
For bikes you'll see dedicated speed limit board with cars and LMV
Hai Abhinav.
I have a doubt.
Is it ok to revv high for too long on highways with this setup. I am planning to shorten the gears for more bottom end, but also skeptical to take it on highways long trip.
How fast do you intend to go on the highway for long? Keep it around 7k and you'd be okay
Do you have a link for ordering the 14t sprocket?
Heyy you said that there might be SPEEDOMETER error as the bike measures speed using the front sprocket.
Did it change? And isn't the speedometer sensor on either of the tyre?
Hi. The bike measures the speed from the front wheel and not the front sprocket on the KTMs. I checked later on a paddock stand. So no speedo error.
@@abhinavbhatt okkay!!
Great.. But is there any speedometer error since u said in the earlier video that it was calculated on sprocket rotation. Usually it is on front wheel.. no idea abt 390 adv
No. I was wrong on that. It is calculated on the front wheel. So no error whatsoever.
Abhinav, good stuff!
Can the sprocket change be done at the KTM service centers or do we need to take it to a local mechanic? Also, any idea if this gonna impact the warranty?
I don't know about warranty but my KTM service centre happily changed it for me.
The speedometer will now show 7-8% positive error after switching to lower teeth sprocket. But I think it is managable.
No, it won't. The speeds on this bike are measured by the front wheel. I checked on the paddock stand.
Also, I am close to 2nd service (10k kms) of my INT 650. Kindly suggest which engine oil and flush should I use?
If you want to retain warranty, stick to what RE recommends. If you can do without it, Liqui Moly Race Street is very good. I use it.
Sir is the bike suitable for a tall guy (6feet.2inch)..and what about r15
It should be, but standing up and riding will be difficult. R15 would be cramped for a 6'2 guy.
@abhinav bhatt: with lower tooth sprocketing I believe you are looking at comparatively shorter drive chain life and a slight sacrifice of the top end. But regardless, I suppose for daily riding and sedate cruising going one tooth down makes sense. Also Rolon chain alone only costs about 800-900 in the aftermarket scene so shouldn't cost you a moon when the time comes to replace it.
Yeah, with parts this cheap, I don't mind changing the chain sprocket set every 10,000 km. Even that might take me two years, since my riding/driving is spread over four-five bikes and two cars.
@@abhinavbhatt I am curious to see how it affects the most expected "FE" topic and increment in rpm for the same speed Vs stock tooth. If I am correct you are looking at roughly 500 rpm increment for the same speed..
Abhi....where is your yezdi adv, hero xpilse 4v videos?
eagerly waiting for r15 videos
Next Video: Suspension tweaks for more softer ride.
Any help with the fork adjustability?
I would love to have the option of softer suspension at the rear. But no changes yet.
Hi Abhinav,nice work.Where can you procure only sprocket, because in our city KTM dealer is only selling whole chain sprocket kit.Please guide
I bought it from my KTM service centre. They are bound to sell you any part you want.
@@abhinavbhatt Thanks for reply.I will ask them.
I have a question. I'm using ktm 390 adventure. I want to install front sprocket 14. but I could not find the original part where I was. Does the duke 250 front gear fit?
Yes
@@abhinavbhatt thanx bro 👍
what about the ECU? Does it have to be programmed with the sprocket change? Because it might not match the preset calibrations of the stock settings on the ECU. Have you done anything concerning this?
I don't know if it makes any difference to the ECU. I have ridden the bike some 400-odd km since the change and haven't faced a single issue so far.
Rajat Yawalkar This one is my concern too
It is not required
@@abhinavbhatt I don't think it might come across as an issue necessarily, but maybe the odo or other readings might not be accurate? That's what I'm concerned about, that the ecu wont necessarily malfunction, but might not show accurate indications? Even if that does happen, how could one realise that it's not accurate?
PS: Actually I'm very excited and curious at the same time because my adv390 delivery is tomorrow.
@@rajatyawalkar1274 Congratulations on the new bike. I will test whether the numbers are accurate or not.
Wowww really wonderful♥️..i guess u had ur PhD done in bike mechanisms..oki please explain can we convert bs4 engine into bs6 engine just by changing somethings like catalytic converters and all.??????
Hi. Even if you would swap the exhaust with the additional cat con, the RTO won't classify your bike as BS6. I don't think one should even bother with it.
hey bro i wanted to know what will happen if we change both front and the rear sprocket from D250 in a D390.
What is the size of a Duke 250 rear sprocket?
This being an adventurer tourer am more interested in knowing how it would handle something like a trip to ladakh or a bit more adventurous like sangla valley. Now I know technically every bike can pull that out if you know your bike inside out but still as am hoping it would be a trendsetter in that category.
I think it would do perfectly fine. A guy (UA-cam channel: Dream Chaser) just did Spiti on it. You might want to take a look at his series.
Hey Abhinav, can the front sprocket of Duke 390 also be replaced by Duke 250's? This is also specifically in line with the knocking problem.
Hi bro did you replace it ? If yes kindly give me the review
@@darshanraut554 I didn’t man! Been living with it.
Is KTM gonna solve the quick shifters problem?
By any ecu update or something??
Or will it be the same?🤔
I hope they do. It is bad enough KTM India thought skipping adjustable suspension for India was a good idea. The damn quickshifter - and who the hell needs a quickshifter on a touring bike - is harsh. I don't even feel like using it.
Hello Abhinav!
If I'm not wrong you live in B-"x", Vasant Kunj.
Btw I really enjoy your videos!
Regards
Yeah. But let's not reveal that 'X', please :)
Bro i also felt the small lag in low eng on my bs6 duke 390 can i change the front sprocket ... Will it affect the initial pull
Yes.
@@abhinavbhatt tnx for the reply bro.. Is the drop in initial pul noticeable
Is there any issue while gear changing with quick shifter after this mod. Will it affect millage ??
Quickshifter feels a bit hard. But it always did. So I won't attribute that to the smaller sprocket.
Hi abhinav. My dealer told me that would create problems with the engine. Should I trust him or just go ahead and change the sprocket?
Are they speaking out of experience? I have been using it for a week and I haven't faced any issues.
@@abhinavbhatt cool then I would also try and get it done. Thanks much
Hey Abhinav, can we get this done to a new ktm 390 adv?? Like as soon as I get it...?
Yeah.
What camera and mic setup?? It's Soo good
GoPro Hero 7 with mic adapter. Some generic Amazon Rs 350 mic.
Which is the engine oil you mentioned ?
Bro, this upgrade, of the sprocket. You said that there may be a change in the actual rpm and the rpm on the instrument cluster, is it so? And did anything else changed because of the new shorter gearing besides low end?
What I meant was the bike has to rev more to maintain any speed due to the shorter gearing now. There are no false readings at all, if that is what my message conveyed. Top speed is down to 166 kmph.
@@abhinavbhatt okay okay, thanks for the info.
Honestly I do agree with your techniques..
what about the speedo error that you talked about in the last video ? and plese make more videos about the mods on the interceptor. ma dgood content
No speedo error. The speed is calculated from the front wheel. I checked on a paddock stand.
I Had The Same Problem But When it crossed 2k km It's good now
but still it make confusion between 2nd and 3rd gear.
If you fix the lower end with bigger front sprocket, you will reduce the top speed. Increasing brake horse power is the only way to increase both
Beast mode on @ 9:10 😍🤩
I'm going on touring..
is about1000km (on road)
I was thinking to get ..
KTM 390 adventure or honda cb400x
Any advice which is better ktm390 or cb400x?
I'd pick a twin over a single any day for touring.
