He 2WheelsGood,

I do hope you will not give me the same Snaer you did Ede (who in my perception asked a genuine question given the initial information) but rather than continuing guessing, it actually is the best to visit a real KTM dealer that knows about the Duke (preferably first AND second generations) and drop your concern there.
KTM is a well-established brand and I can think of no other reasons for this company to alter certain things other than to improve them to satisfy riders experience.

The double set up fan in the video I have seen first about 3 years ago on an Indian guy's Duke 200 first gen touring from India to Malaysia and who told me back then it worked very well.

For bike wreckers as in the video, these people hardly ever move in a straight line and as such need to find ways to get enough airflow through the radiator to cool down the engine enough especially with the constant revving to please the public.

For us mortals (and more genuine bikers) it would be prefered not to close the rear of the radiator off completely in order to have the straight line "natural" airflow passing through.

The only last thing I like to comment on your particular issue is the ty-wrap mounts that I think are not the way this is meant to be mounted looking at the parts drawing.

I hope you'll find the answers soon and share.

To clarify, I’m not saying it’s held in place by zip ties. Only that extra little flap at the bottom seems to have a zip tie keeping it from flapping around more than it already does.

Was just at a dealers looking at the 390 and 2 new 2018's both had these shield things on. (uk)


Very strange. I was at the dealer yesterday, and one had it and one didn’t.

According to the guy at the dealer, my bike was made in June of 2018. Maybe it was right around that time they started putting them on. He wasn’t sure when the change was made, but it appears that it was some time in the middle of 2018 as many 2018s don’t have them.

Interesting....It does seem the reason is to steer the heat drawn from the fan away from the rider. I do hope so because i'm still on the fence about buying this bike and the heat from fan is 1 of the things putting me off (bike will be used in HOT Africa.


Where r u located?

San Diego, California. I’m near the coast, so it never gets very hot (or cold) around here. But for what it’s worth, I’ve never felt hot air blowing on me when the radiator fan is on.

I live in hot Bangkok and the fan is running very often. I wear long jeans and I never felt that it is uncomfortable hot. Maybe with shorts its too hot but in my opinion shorts and riding on a bike like that is anyhow a bad idea.

Is your fan on often 2WheelsGood?

And did you ever ask the guys at dealers what the rubber sheet thing is for? I thought about asking today but could tell the sales guys was "a sales guy" by his answer to another question i asked and knew he's just make something up.


What year is your bike Ede?

I talked to three different people, including two mechanics. Given that there’s a 2018 on the floor without one, it’s not certain as to why exactly. The one most knowledgeable dude said KTM often makes changes like that, but doesn’t tell anyone why. Being that it’s listed in the parts blowup, it’s obviously not a forgotten piece of packing material. Some of their 2018s have it and some don’t. They must have started doing it right about the build time of mine, because mine was built in June 2018. Everyone’s guess is that it’s to direct hot air to the side instead of blowing it right on the rider’s leg.

As for the fan, I wouldn’t say it’s on often. Maybe more often than other bikes I’ve had, but this is also the worst traffic I’ve lived in... even with lane splitting.

My bike is a 2017 Duke 390, I bought it in May this year in Bangkok.


I like the temperature management from this bike. Previously I had a Honda VFR400 NC30. It had a fan but the fan only switched on when the temperature was already high. Then sometimes, especially in stop and go traffic, the bike just got too hot.


With the Duke the fan switches on in the middle of the temperature range (4 bars out of 8). It runs, cools the bike a little, and switches off again. All within the 4th temperature bar.
Worst case every I had 5 bars on the temperature range - well within good working temperature.


I use Torque App from time to time to monitor the engine values. I had intake air temperatures of about 50 degree Celsius and the fan made sure the water temperature was still on 4 or max 5 bars.


And I never moved my legs just because it is too hot. Sometimes it's a little warm but entirely acceptable.

Did you sit on both of them?
I saw the MT03 next to my Duke and the MT03 seat is significantly lower.
I am 186cm tall and I can flat-foot the Duke - just about. I would not recommend it for not so tall people.

Re: MT 03; Yes i sat on 1 today & a few weeks ago, i'm around 6ft and they both feel fine to me.
I think i want the Duke more, its seems (as nuff ppl say) more fun, but its just the reliability i'm worried about, especially having no dealers in Africa.

I am sure there are people here who are more qualified than me to discuss this.
But it seems the KTM is not the easiest motorcycle to work on in DIY fashion.
What would you do i.e. if your TFT screen does not work in the way you want? Buy a new one? Even if you have warranty?
If there is no dealer that would be a reason for me not to buy the bike - any bike with no dealer.
Exception of the rule is if you have a couple of bikes and you don't mind if you send one bike somewhere far away to the specialists whenever necessary...

Right.......Its the same with Yamaha, no dealers there...but the Yamaha is more reliable.
If only KTM's quality control was how it should be i'd deffo get 1...How it is now i could get 1 and get a perfect machine n have zero problems or get a friday afternoon model riddled with problems. Main things im concerned about is clutch problems, valve clearance after 1stt 600 miles and over heating.

No problem. But I think you should take reliability ratings and internet anecdotes with a grain of salt.

I think my story is relevant to your situation. This KTM wasn’t my first choice. I initially steered away from it because I too was afraid of its reliability history. So I bought another bike in the category that should have been far more reliable. After 3 weeks and 300 miles on the bike, the water pump went. I took it to the dealer, and they also found engine issues. My three week old bike was in for service for over a month! When I got it back, it started leaking water again. That’s when I got a lemon lawyer, and I’m currently in litigation to get them to buy that bike back.

So far, I haven’t had any problems with my KTM.

The point being, we don’t live in a perfect world. Just because a bike might be more reliable on paper, it’s no guarantee you won’t have problems. And I’ll tell you what, the KTM is WAY more fun than my more “reliable” choice.

So don’t let your decision be driven purely by horror stories you’ve read on the internet. Go with the bike that speaks to you, and take a risk. It’s a risk either way.
