Final Drive Gearing KTM Duke 390 125 200 250
How do you ride? Stunt, track, supermoto, street, adventure, commute? The list is endless but your bike only comes with one set of gearing. Does it work for you or could you customise it to suit you a little better. In this video we discuss what you can do to change your bike to suit you better.
If you have a 390 and ride long distances or fast I recommend changing to a 16 tooth front sprocket. If you do a lot of low technical riding say in heavy traffic then try a 14 tooth front sprocket. If you are riding a 125 then the engine has less torque so be careful about making the rear sprocket smaller than 45 and a 15 tooth front sprocket may cause you to lose acceleration and top speed.

Very educational. Love watching your videos.
Awesome video as always. I'm learning alot
Time you got a new mitt from Halfords Dave 🤔 seriously though, love your videos. I'd be lost finding my way around the 390 without your stuff! Please keep it up!
Thanks for the video David! Good to see your videos again. I wondered how your acceleration had changed with your 50 tooth, this answers my question!
You always have a nice explanation on every subject. I bought a 46 tooth rear sprocket from KTM power Parts and keep the 15 tooth on the front. I found no diference on riding.
Good practical info!! Thanks David!!
A darn sight easier than my old T140V 🙈 Great too see you mate 👍🏻
Well explained, another consideration not mentioned is that going more than one tooth down in the front usually adversely affects chain wear due to the chain being pulled in a tighter radius.
Again you are very correct, with my engine swap i had ran trough a large combination of sprokets
New follower,🥇👍❤️😎🤩✌️🥰👌🏻👋🎉🇮🇳🙏😍🥳💝🍻😊😜🤪👌👌🎉✌️😎👍🥇 keep going buddy love from 🇮🇳
Nice video it was very informative
Nice video love the intro
Would love to come on a ride when its finally finished. will be fun
great content!
I bought my first motorcycle (2021 duke 200) about two months ago and your channel has been a blessing! Thank you for the good information and taking your time to explain things thoroughly!
Love the content you provide. I’m finding my 14’ 390 too jerky in slower traffic. Would you recommend the change to 16T as well or is that just for smoother gears on the top end.
Love your content mate! My rc 390 adac cup, (road legal) super bike has a top speed of 190 km/h.
Great video , I love my 200 2016 duke , short commute bit slow at higher revs on dual carriageway , which front sprocket + 1 or 2 teeth for slightly higher 60 - 70 running on lower revs , thanks
Hi David, love the video! I have got a KTM 125 Duke 2019 with stock gearing. I am thinking of getting a 15T front sprocket instead to lower the revs a bit at high speeds. Do you think that would work? Should not bring the acceleration down that much right? thinking of that you said that a front sprocket change on a 125 might worsen both acceleration and top speed.
Hi, thanks for this! Just to confirm, if I want to city commute more "smoother" (higher rpm = less jerky in slow traffic, so not having to slip clutch all the time) on my '19 Duke 390, without losing too much at top end, would you recommend just going to 47T on rear? KTM Powerparts just offer a 46, but that would be barely noticeable right? Thks
