  1. KTM Duke General Discussion
    Hi, new to the forum. And glad to be here. So, I've just gone and bought a 390 duke, however, I've just ordered an exhaust. It hasn't arrived yet, but when I just looked on the Info for it, it said 2017 - 2020, which has baffled me because I'm very confident it said 2021 - 2022 when I bought...

    Good day folks ….. I am looking into removing the silencer box on my 2021 390 Duke and was wondering will it compromise anything by doing so …… I want more sound from my exhaust and the aftermarket exhaust did squat to help with that …. Thanks in advance ….. Happy Riding All !!!
  3. KTM Duke General Discussion
    Hey Guys, Pretty new around here. I just got a new KTM duke 390 2021. If I am getting it right, this is a BS6 engine, since the exhaust goes below the engine. My main concerns are connected with buying a new exhaust. I want to buy an exhaust that will not need any reprogramming. Is my only...
  4. Exhaust And Fuel Delivery
    Is anyone aware of how big the 2016 KTM 390 Exhuast is, and if it ran the same as the 2017s? Really not liking the wait time on an IXIL underseat & might as well just custom make one at this point. FOund a really nice dual underseat system for the 2017 bodystyle, but will it fit? link below for...

  6. KTM Duke General Discussion
    My first post here, Hi all! I have owned a 2018 Duke 390 since October, bought with the intention of both myself and my wife using it. It’s a great little bike, but my wife hasn’t really had the interest enough to rekindle any desire to go out on it (she used to own a VFR400R NC30). So, this...
  7. KTM 390 Adventure General Discussion
    Hey all, just checking to see if anyone has done this before or knows if the frames would line up in a way that would even allow it. I am prepping my 2021 390 adventure to do a little more serious offroading this summer and am trying to gain ground clearance. I am currently trying to figure...
  8. Exhaust And Fuel Delivery
    Hi everyone, I was wondering if anyone knew whether or not a 2020 spec Austin Racing GP1R slip on can could be fitted to a 2021 duke. I know the exhaust routing has been changed for this year. Just wanted to ask around before dropping nearly £500 on an item that might not fit. Many Thanks

    Hi, Everyone I have a '14 390 and I'm quite tired with the stock "coffee pot" exhaust notes and wanted something more bass-y without the need for a fuel controller/ECU piggy back. Has anyone tried doing a v2 catback exhaust on a v1 390? Now, I'm curious if we can only use the v2 catalytic...
  10. Exhaust And Fuel Delivery
    I recently bought a 2019 390 duke. It has a full delkevic exhaust (no cat and their muffler). It’s too loud for me. Like if I’m not wearing earplugs, it’s uncomfortably loud (I wear earplugs when I’m riding for more than a few minutes, but even just a few minutes is too much). So, I’m looking...

    Hey i am about to recive a 2021 duke 390 and i was looking for exhaust options. I know the 2021 model has a different exhaust system due to euro5 So im curious if a slip on for the 2020 model wil fit the 2021. No car delete or anything like that just a slip on muffler. Planing on arrow thunder...
  12. How To & DIY
    If you own a Duke that has the exhaust pipe routed above the engine case on the left side you are probably thinking that KTM engineers like their left leg baked to perfection in the summer. I don’t, so I bought this aluminium exhaust pipe protection/heat shield for dirt bikes from China for like...
  13. Service and Maintenance
    What’s the best way to clean this exhaust residue off?
  14. KTM Duke General Discussion
    Would a Rapid Bike Easy supply enough fuel to change the exhaust to a slip on exhaust?
  15. KTM Duke General Discussion
    So I didn't check the bolts on my exhaust guard and it fell off somewhere. Does anybody that upgraded their exhaust still have one laying around they would be willing to part with??? Thanks in advance.
  16. Engine and Technical Discussion
    Hello. Just bought my first Duke 390 2014. The jerking in low speed is bothering me a bit, since I do a lot of city riding. Which tuning box do people recommend, and what is the most cost effective option? Is there any horsepower increase on these powerboxes? The bike is completly stock...
  17. Issues and Troubleshooting
    As many of you I decided to replace the original muffler with a less restrictive one, I chose this one with a decat: I was really happy with it; good sound, low weight, and looks nice After some month I installed a Rapidbike Evo and a new decat pipe: After that I realized that with the...
