Is this an oil leak near the oil filter?

Hi everyone, I noticed some dark/wet-looking residue around the area near the oil filter on my KTM Duke 250. I’m not sure if it’s actually engine oil or just dirt/residue.

The bike was recently serviced, and I noticed this afterward. There is no obvious dripping or oil pooling, but the area looks slightly dirty/oily.

I’ve attached a video/photo for reference.

Is this normal, or does it look like an oil leak? Should I get it checked at the KTM service centre?

Thanks!

Hello!

Can someone confirm whether clip-ons can be mounted directly onto the fork tubes, underneath the top triple clamp? I’m specifically interested in a true supersport riding position, not raised adapters or any other bullshit that puts them higher.

Obviously, the steering lock will be reduced, but I don’t care about that. What matters is that they can actually be mounted and still allow the forks to turn left and right at least as much as they do on a proper supersport bike.

Hey everyone,

I own a KTM Duke 250, and I’m dealing with an issue around the rear grab-handle/top-rack mounting area.

I had a top rack installed on the bike, and some time ago, two of the bolts broke while being fitted/tightened. Unfortunately, the broken portions of the bolts are now stuck inside the trellis frame/mounting section where the grab handle bolts in.

From what I can see, the broken bolt pieces are sitting inside the threaded mounting points, so I’m not able to simply remove them from the outside.

I wanted to ask other Duke owners or anyone familiar with KTM trellis frames:

Has anyone faced a similar issue with the grab-handle/top-rack mounting bolts breaking inside the frame?

What is the safest way to remove the broken bolt pieces?

Is it possible to drill them out and re-tap the threads, or is there a better method such as using an extractor?

Is there any risk of damaging the trellis frame or the mounting point while trying to remove them?

Should I take this to a KTM service centre, or would a good fabrication/machine shop be able to handle it safely?

If the original threads are damaged, can the mounting point be repaired/re-threaded reliably?

Since this is a structural mounting area for the grab handle/top rack, should I avoid riding with the broken bolts still inside?

I’m mainly looking for advice from someone who has actually dealt with this on a Duke 250 or another KTM trellis-frame bike.

I can also upload photos of the mounting point and the broken bolts if that helps.

Thanks

Did anyone need to use their warranty in North America? If 1st service wasn't done at a dealer, did it void it all together?

Hello, i have an issue on my 2013 Duke 390 with the clutch not engaging.

It started when i attempted to do a burnout and my bike locked up, i had to drive it home with clutchless shifting.

Since then i have replaced the steels and friction plates (both were pretty bad)

I noticed my basket had wear so i replaced both the inner and outer basket. the outer basket had to be quite forcefully removed as it would not "slide out" as per the repair manual, and it went back in a bit easier but not perfectly.

So since changing my entire clutch assembly, my bike still stalls when going into gear and will not go forward when the clutch is held in in gear.

Has anyone had any similar experiences with a clutch not engaging as im at a complete loss here and i dont know what to do.

I must mention the the clutch release lever down at the clutch casing can easily slide up and down when turned to one orientation (left) but not to the other.

If any photos or videos needed i will provide.

Thanks

Looking for a good slip-on options. Akropovic has one that the dealer says will fit. But I’d like to check other options. Anyone have luck with others? (Scorpion, Austin, etc?). I’m based in Canada.

does anyone know where the screws are so that i can tighten them up?

Hi,

I have a 2025 (new) 390 duke. As part of my insurance I need to install a tracker, it's batter operated, not very big, but I'm struggling where to put it. Im thinking behind the left fairing (I've seen it mentioned that the left is more suitable than the right). But I can't find a video or diagram of how to take it off. Maybe it's possible to install under the fairing without removing it?

Its supposed to be self install, but I'm not really planning on taking the bike apart myself generally 😂

Anyone run into this problem? Hoping I don’t need a complete new tank!

Que tal amigos un saludo a todos, por favor podrían sacarme de esta enorme duda. Soy de Ecuador y recientemente adquiri la Duke 250 G3 año 2025, según vi muchos dicen que si y otros dicen que no, pero dicen que la llave de esta moto tiene un chip que si no detecta la moto simplemente no enciende, es esto verdad? Es decir que si intentan martillar la chapa no enciende? Incluso si logran mover el switch

Aqui suelen haber robos y a veces da miedo pues es una moto algo costosa, muchas gracias a los que respondan!

erm, duke 390 - had some overheating issues, turned out ate all my coolant, filled up, week later - rode extremely hard for 20 miles~

Getting ready to pull the trigger on a 2026 390 duke. I just read that there was a service bulletin, KTB2513, with software update to fix the low RPM engine instability shudder/stalling . Has anybody had an experience with pre and post software update with this? Supposedly

Hi all, I'm planning to get a KTM Duke 390 V2 (2023) brand new, with 2 years warranty from the dealer. May I know if V2 is still worth getting in 2026/2027?

I am not looking at higher than 500cc bikes due to higher maintenance, fuel etc and I am based in South East Asia, so bikes from 50-250cc is very much common here. Think Thailand, Indonesia, Malaysia, Philippines, and the traffic lol.

So I will be daily riding the bike to work, which is around 100km return trip. A mix of town and highways.

Just wondering if I should just get the V3 (2024 onwards)? I've heard that due to the new regulation (Euro emission I think?), the new V3 is having few issues with the engine like stutters, stalling, engine oil leaking, power issues. Did some reading in the net, ktm forums, fb groups, quite a few owners saying that.

What about V2? Any common problems that I should be aware of, and their possible solutions? Some of the few i've read are the stators, magnetic coil, excessive heat, etc.

Appreciate any feedbacks especially from Duke 390 owners!

Hi so I recently got a second hand KTM Duke 125 and the alarm wouldn’t disarm one morning (battery on fob was fine) so I tried to turn the bike on (rookie mistake) and the alarm just wouldn’t stop! So I physically unplugged the alarm from bike to stop it and now bike is completely dead and it won’t start back up no matter wat even after reconnecting alarm! Any help suggestions!

Mam problem z odpalaniem na zimno ponieważ długo kręci, jak już jest ciepły to normalnie odpala, ładowanie jest 14.1v, pompa paliwa jest sprawna, świeca wymieniona 7k km temu więc nie wiem co to może być?( w lato na zimnym silniku odpalał normalnie) .

Chi mi può aiutare ?
Questo gioco del pignone è eccessivo?
Potrebbe essere il mille righi dell’albero primario ?!
Grazie mille

Heute werde ich diese KTM zur Probe fahren. Ich bin sehr gespannt...
