Simple Oil Change KTM 390 125 200 250 Duke

I really appreciate detailed step by step instructions. It made the job super easy. You saved me lot of time and pain figuring out how to do it. Shame I can give you only 1 like on the video. Thank you very much!

Thank you for this video. l just changed the oil on my Duke 390 and had a part left over in the kit. After watching your video l learned that it was an oil strainer that fits in the drain plug hole, which l had no idea about. I drained the new oil out, fitted the new part, and was able to save the oil and put it back in.

[@MotoMirius]

Good job. Figuring out where the extra parts you have left over at the end of the job go is the biggest challenge!

[@AaronCohn84]

Great video, thanks so much for sharing! One note about the bolts on the oil filter cover: the bolts may not be 12 NM on all models. On my 390, they are 8 NM. If you try to torque them to 12 NM, you will either snap the bolts or strip the threads. Make sure you read the manual for your model!

[@MotoMirius]

Thanks - what year is your 390?

[@AaronCohn84]

@@MotoMirius 2016

[@MotoMirius]

@@AaronCohn84 Interesting. The parts diagram shows that the 2016 and 2017 use the same bolts yet in 2017 KTM have increased the torque to 12NM - which suggests that they won't snap or cause other damage regardless of whether you have a gen 1 or a gen 2.

[@AaronCohn84]

@@MotoMirius I attempted to use 12 NM after watching your video, and the result was 1 snapped bolt and 1 nearly destroyed. I was lucky to extract the broken bolt without much trouble. I got some new bolts from the store, which were made of higher grade metal, and attempted to screw those in at 12 NM. The result was stripped threads. In case there’s any doubt that my torque wrench is operating correctly, I successfully torqued the drain bolts to 15 and 12 without any issue, and it was fine when I had it set to a lower torque, like 5 NM. So pretty much it’s just my brain that was not operating correctly 😖

[@MotoMirius]

@@AaronCohn84 12Nm is what KTM recommend, and this is why I recommend it. My personal opinion is that the Indian sourced hardware used on these bikes is sometimes sub-standard. It also assumes that your bolts have never in the last five years been overtorqued or the case threads otherwise strained or poorly tapped at the factory, all or any of which could create the result that you've experienced. I appreciate that you have had a poor experience, but is the reality of working on vehicles even when you do everything right. From your comments, KTM appear to have increased the torque spec on these bolts and that is unlikely to be a random or accidental change but probably the result of dealer feedback. If you check the online torque ratings for a 6mm socket head bolt, 12Nm is fairly common - but does assume that an appropriate grade of steel has been used.

[@jagathhettiarachchi9373]

Dude, your video s are fucking awesome. Thank you and keep up the good work. I bought my duke 390, and so far I could solve all the issues without getting it to those half educated so called service dealer guys. Your explanations are so good and clear, so anyone with basic psycho-motor skills could easily take care of their own bike rather than spending long hours and lots of money on regular maintenance. thanks again man, may god bless you!

Good idea to remove the filler cap when draining the oil too.

[@MotoMirius]

Indeed, and when you do so is the subject of much debate. In practice I can't say I've noticed any difference, I always do it after removing the drain plug and with a multiple drain and filter setup like this there is plenty of air getting into the system.

As always a fantastic video! I followed your instructions step by step today and successfully changed my oil, filters and screens without hitch. Although, I couldn’t find a magnet anywhere (I can confirm fridge magnets are not strong enough lol), so I gently hammered a small tack in to the centre of the old oil filter enabling me to pull it out. You have given me the confidence to tackle many jobs on the bike. I recently swapped out the decat pipe for the arrow pipe and kept the pre silencer (as recommended), it sounds absolutely awesome….plenty loud enough. One quick question, what adjustable torque wrench do you use? I need to invest in one so any advice would be most appreciated. Thanks.

[@MotoMirius]

Great improvisation! I think KTM recommend circlip pliers for the job, so it really depends what you have to hand. I have several different torque wrenches, all of different makes - one won't work for everything on the bike - the one I used on this is an old fashioned one from Britool. I don't have a recommendation for brand, but it needs to be a decent make with a good reputation, and not a fake or copy.

[@Welcometotheshow]

Hi thanks for all your KTM videos they have been an integral part of my Duke ownership,can you clarify when checking the oil level window should the bike be on its side stand or upright?

[@MotoMirius]

Thanks. The bike must be upright with the oil at operating temperature.

[@gordonchan6014]

hope you could also show us how to change brake pads, front and rear, and which brand and model suits. newfren and brembo are more accessible for me . so appreciate if you could advice on these 2. thanks a million.

[@MotoMirius]

Buy pads from a reputable maker. Here I buy EBC. There is little special or technical about pads - so be careful to avoid paying just for a brand name, but also don't buy cheap or fake because these can be badly made. Stock pads on the front are sintered on the gen 2 bikes - no point in changing them, you won't get better braking on the road from Brembo pads. I use sintered pads back and front - they will wear the disk out faster but they brake better - but don't go overboard on the back unless you race - KTM didn't fit sintered on the back, because you don't need them unless you trail brake a lot.

Great video, will be very helpful when the time comes to service my Duke 125. Looking at 3:15 - would you suggest to get cover protectors for the clutch and gearbox covers ? KTM sells some orange aluminum protectors for that. I see that your Duke was scratched quite a bit in that place. Cheers 🙂

Hi mate New to the bike world and just bought a 2021 duke 125 and reached 1000 kms.What oil will i use on the change.Loving your videos mate thanks alot..

[@MotoMirius]

Thanks. KTM recommends 15w50, sometimes I use 10w40. KTM recommends Motorex - because that is their oil partner. Most oil companies have a website, and often have an oil finder that recommends the right oil of theirs for your bike - Motorex for example has one and gives a couple of alternative oils. Don't use car oil, you need one that is designed for a wet clutch, oil spec should be at least JAO T903 MA2 - it will be in the description but most bike oils from the major manufacturers will meet this.

[@larrybyrne4082]

I have the KTM Duke 125 it’s it the same to change the oil as you have shown in the video if so Big thanks it was very helpful for me as I am now rider Thanks Larry

[@MotoMirius]

Hi Larry, yes the process is the same, the 125 takes less oil because it is a smaller engine. I believe it is 1.2l for oil change and 1.5l with filter, but adjust as needed using the sight glass. Good luck!

[@gy8132]

Excellent content in clip, much appreciated sir. Drained my oil duke 390 2016 yesterday, noticed oil has water contamination. From your experience have you replaced the seals behind the water pump impellor, if you have carried out this work can you access both pump shaft seals after the impellor has been removed? Thank you for advice Mr Moto Mirius.

[@TheJWC56RSA]

Great video - as always! I find it strange that KTM wants the oil level to be checked with the engine hot... When my 390 is at operating temp. and the bike is upright the oil level is between the min. and max. mark on the sight glass as per KTM instruction... however when I check when the bike is cold I do not actually see the oil in the sight glass.... Not a good practice as one now assumes that the bike has enough oil - and that is as you start a journey. I spoke to the dealer as I was told not to add any oil....

[@MotoMirius]

Yep. That’s how it is. If you bear in mind that KTM make dirt bikes it becomes much more normal because a lot of dirt bikes run dry sumps - which you have to check when at operating temperature. I very much regard the 390 as a dirt bike in design and now I have decatted it, it sounds like one too! I must admit though, the oil checking procedure is one I dislike and I never liked it with any dry dump bike either. Skäl. David

[@KROWARIZONA]

The manual indicates to check the oil levels after you use the bike, not when it is cold.

[@TheJWC56RSA]

Correct... even KTM dealers complain about this... it is stupid! No one should ride a bike if you can not see oil in the sight glass when you start your journey.

[@MotoMirius]

I agree but... this is normal on many bikes. It’s necessary to learn to check the oil at the end of the ride instead of at the start. Much like its better to oil the chain at the end instead of the beginning of the ride. Skäl. David

[@TheJWC56RSA]

@@MotoMirius .... with all due respect, I think a lot of damage can be done by riding with too little oil - so I always make sure the oil level is correct before I ride. Better be safe than soŕry!

Awesome. Have 4 litres of Motul 300V Factory Line 10W40 4T arriving any day now. Just ordering the Filter service kit which I had NO idea existed until I watched your video so thank you for the heads up. Quick question - how often to chain the oil (miles or km) and how often to change the filters and screens?

[@stangoodvibes]

'change' the oil, not 'chain'. Doh!

[@stangoodvibes]

Hmmmm thinking I might change it for the 15W50 for Australia. The winters aren't *that* cold.

[@MotoMirius]

Hey David. Great to see you pushing ahead yourself. KTM recommend oil changes every 7500km or once a year, whichever happens first and to clean the screens at the same time - change if damaged or the seals are going. Personally I tend to change twice a year and if you lay the bike up for say winter then change the oil before you do. Never hurts to play safe and change the oil too often! Good luck. Skäl David

[@MotoMirius]

I'm always in favour of tweaking the oil to your local climate.

Cheers for the video mate, really useful. Did that damage on your engine case happen before you had the crash bars, or with them installed?

Thanks. Engine case damage when the previous owner wrote the bike off. KTM crash bars or case sliders are highly recommended. I wouldn’t recommend any of the aftermarket alternatives aside from the Chinese KTM copies - so long as you can live with colour not matching. Stunt cages are also fine.

Hi there, love the videos. I see they sell 4 liter bottles of Motorex 15/50. If the 390 Duke needs 2 liters what is the best way to measure this? Is it just pouring half of the 4 liter in? I just want to be precise and sometimes it's hard to see inside the Motorex bottle to see if it's half way. Thanks.

[@MotoMirius]

Thank you. KTM don’t recommend measuring like that, and it’s always difficult to be precise with the bottles. Fill to the correct level in the sight glass. Then bring the engine up to temperature and then top up to the correct level. Skäl. David

If your bike doesn’t have traces of oil around the shift lever area then you probably aren’t putting enough oil on the chain. You will get oil on the filter cover if you spill any oil when filling - especially likely if you have crash bars getting in the way. Skäl. David

Oil capacity is 1.7l but there will always be residual oil in the system, always check the level instead - so if you add 1.7l you may overfill. Add oil, bring the bike to temperature and check level - it is easier to add a small amount of oil than to remove a small amount of oil

G'day David, Just completed a service on my Duke 390, All has gone well however I am concerned with the amount of oil I have put in and what the level is telling me vs what the service manual says. I followed the instructions completely and replaced both oil screens, oil plugs, all o-rings and drained the oil completely. So far I have added 1.8L of oil to the duke and run the bike to operating temperature, the sight glass, however, reads barely above the minimum mark, I believe this is due to the fact I have replaced both oil screens and the filter, all 3 will absorb some of the oil to a degree. Your thoughts as always would be greatly appreciated. Rohan.

[@MotoMirius]

Hi Rohan. The service manual does not specify the total volume of oil to be added. It’s process is: change filters, add 1.7l, bring up to operating temp and stand the bike upright. Then add oil until the correct level. It sounds like you just need to add more oil - with the engine at operating temperature. Skäl. David

Rock oil has a good reputation. I use both systhesis and guardian in my bikes. I've also used one of their more off road spec oils for this bike. If you look at their website (and the same is true of most oil companies) they have a bike finder which will recommend oil for your bike and you can then choose which suits your use and budget. The more you blat the bike, the more you should spend on oil. If you just cruise around town trying to get the maximum mpg then guardian is fine.

The screen can get clogged so it's best that both drain plugs are useable. On an older bike the risk of the screen clogging is lower so you might get away with it.

Was the oil normal when you changed it? If it wasn't then there can be a failure of the seal on the water pump. Sometimes the oil pressure switch can be faulty and gives this error. Otherwise you should get a KTM dealer to check the oil pressure. Good luck

@@MotoMirius Actually KTM dealer is a bit far away to me so, i got some helps for chaning oil and oil filter from a local mechanic. I told him "low oil pressure warnning". Probably he didn't understand me. He mixed it with service warning. I will call KTM dealer as soon as possibly. I will tell them about your advides. Thank you so much.

[@MotoMirius]

@@erhantiryaki If you don't have a local KTM dealer then find a mechanic who has the tools to check the oil pressure. This error is often a sensor failure - but oil pumps also fail so you really shouldn't run the engine until you've identified the fault.

[@brianjensen4323]

Hey David how many miles or km do you suggest doing the first oil change at

[@MotoMirius]

Hi Brian. First service is 1,000km or 620 miles. You could change the oil before that but it will take that long to properly flush the oil channels out of all the swarf into the screens that they don't bother to flush out at manufacture. Skäl David

[@brianjensen4323]

Hey David one more question do you have to replace the screens and o rings every time you do an oil change

[@MotoMirius]

I would only replace the screens if they need replacing. O rings shouldn't need replacing as they are lubricated and reusable.

[@1966BooBoo]

CAREFUL! - The Oil Filter cover bolts are NOT 12Nm, they are 8Nm, got a sheared bolt due to that error. The front Oil Screen is 12NM, the side one is 15Nm.

[@MotoMirius]

KTM are very clear that the oil filter cover bolts are 12Nm in the 2017 Manual

[@Iam-ix4he]

@@MotoMiriusno its 8

[@MotoMirius]

@@Iam-ix4he Yes and no. The manual, in the section that describes how to change the oil clearly states it is 12. In the general torque sheet it lists it as 8. 12 is a normal level of torque for an M6 bolt. But if the threads are not clean on bolt and engine case then the bolt can bind and shear. Also sub standard bolts can be an issue.

Do you know how to remover the sight glass. Mine has white residue on it. I want to take it out to clean it. I'm wondering if I just remover the circlip and it should pop out but I am not sure.

[@MotoMirius]

White residue is normal during cold weather and should clear up once the oil gets hot and the water reabsorbs. It should come out but I've not tested it myself - I plan on checking the clutch at some point in the not so distant future so I should find out then.

When you say oil needs to beat certain temp, can I just turn the bike on let it tick over for a few minutes?

Yes, that's fine or ride it up and down the road a couple of times - it's just to get it pumped around the engine and warmed up.

Sir I changed my Duke 125 oil I used motol 20w 50 oil it is safe or no safe

[@MotoMirius]

If you are in a hotter country and that is motorcycle oil not car oil then it should be fine. 20w50 would be too thick for colder countries which is why most motorcyle oil is 15w. 20W50 is used in some older style motorcycle engines such as Harley where the oil passages are bigger.

i have a ktm duke 125 2019 model 4 months after the first service engine light kept turning on an off was told its probably a faulty oil switch then it would come up and say low oil pressure but oil lvl was fine plus oil had only been changed 3 to 4 months ago from the first service. went to a garage to have it replaced they took it out had the part on order told me it was safe to ride 10 mins down the road and engine blew. had to buy used 2018 ktm engine had this 1 installed only had 1466 miles on it now im at 1765 ish and im getting the same problem engline light and low oil pressure engine sounds a little different also i have no idea what this problem could be and how this can happen the same way in 2 different engines can any 1 HELP ??

[@MotoMirius]

When the dealer changes the oil, they are supposed to also test the oil pressure to ensure that oil pump is working properly. You also have to ensure that the oil level is correct - this is a dry sump type engine as far as checking oil level is concerned. If you check the oil level with the engine cold then you will not have enough oil in the engine - and it will get damaged. That you are getting the same problem suggests that the oil level is being checked with the engine cold. If this is a KTM dealer then make sure that they have tested the oil pressure. It might be time to find a more reputable garage who know what they are doing.

[@MotoMirius]

@@404hotshot low oil pressure where the level is correct has two most common issues - blockages in the oil galleries - most often clogged filter or screens, or a faulty pump. If you changed the oil and filter then the most likely culprit is the pump. Oil pressure sensor is also a possible culprit so you could swap that out as well - testing is possible but mostly tells you if it works, not if it works at the right pressure.

I am having KTM Duke 125 what grade oil I can use for my bike

[@MotoMirius]

KTM recommend 15W/50. Make sure you use a motorcycle grade oil not a car oil.

[@jackgonez8463]

Do u use full synthetic or semi synthetic does it matter

[@MotoMirius]

Both work - so long as you buy the right ones. Full synthetic supposedly can be changed less often but is more expensive. If you hammer the bike a lot then synthetic can be a good choice, but very much swings and roundabouts - nothing wrong with either, more important to change it to be honest.

[@jaebemblar7308]

Hello sir Can I use 15w40 instead of 15w50 engine oil?

[@MotoMirius]

Oil weight is mostly temperature related. Here in the UK 15/40 is commonly used but if you ride somewhere hotter this could be a mistake because the oil may not offer protection at startup.

You have to run the bike before starting. To correctly read the oil level you must bring it up to operating temperature which you can read on the dashboard.

@@alastairtheduke It means whatever your bike normally reads when it sits at idle after a short ride.

What kind of oil did you use? Thanks

[@MotoMirius]

I use an oil made by a UK oil company. You should use an oil which meets the JASO T903 MA2 standards. Most oil manufacturers will recommend an oil for your bike on their website. KTM recommend semi synthetic and since they have a sponsorship with Motorex recommend Motorex Formula 4T. If you are within the warranty period on your bike then I would recommend sticking with the recommended products to avoid any risk of challenges. I'm currently using Rock Oil Synthesis XRP Off Road 10w50. Skäl David

[@HarimanAbdRahman]

is both the oil strainer the same size?

[@MotoMirius]

It depends on the year. On the later bikes the strainers appear to be the same parts but on earlier bikes only 390 and 250 appear to share both the same strainers.

[@udayysingh.message]

Sir Sorry to say that you have need some oil pour in oil filter then you fit that.

Whilst you can do that, KTM do not agree with you. The process I have shown is as described by KTM. Filing filters with oil before fitting is not usual with this design of filter, and with many filter fittings not even possible. Skäl. David

[@rexxtherider414]

Yes if u fill the oil fiter with oil it will be good for the engine,but in this case it doesn't matter because The filter housing holds very minimal amount of oil and second it is difficult to do that and don't worth and you can't fill it to the full anyways so it doesn't matter

Hi Daniel. KTM spec is 15w50 but here in the UK it rarely gets hot enough to justify putting in an oil with that heat rating but it does get cold enough that I’m comfortable enough dropping below to 10. Rock Oil who are a UK oil manufacturer recommend 10w30. Skäl. David

Can you define hot for the duke?

Daniel Mak hot would be tropics, places like India. I have a video on oil choice that might explain my views on it. As I said in the video, using the recommended oil by Motorex is what I recommend. But the right oil for say India isn’t the right oil for Alaska, so there is room for deviating from recommendations - at your own risk of course.
