  1. 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...
  2. 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...
  4. 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...

  6. 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...

    Would a Rapid Bike Easy supply enough fuel to change the exhaust to a slip on exhaust?
  9. 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.
  10. 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...
  11. 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...

    Hello forum goers. Hoping one of you might be able to lend your experience. I've got a 2019 Duke 390 that I'm trying to fit a LeoVince cat eliminating mid-pipe to. This one. The thing is, this thing doesn't seem to fit. I've removed the stock silencer and pre silencer, and got the top of the...
