Re: KTM 200 Duke

Hello friends. From splus and chinmaykar review it seems the top end is unchanged. Which means max power is at 10k rpm. So anything above that may be difficult. In that case smaller rear sprocket is the best option.

I have stock ecu with 39 tooth rear sprocket. It reaches 145 which is at 10k rpm in good pace but above that takes a long time. I managed to touch 150 only once. But had done 144 / 145 many times.

If remapping gives better low and mid range power then changing the sprocket is the best combo option since u may get the stock acceleration with higher top speed.

By the way has anyone used unleaded petrol till now. Manual says ron91. In India even unleaded petrol is ron91 as per bs3 norms. Premium petrol are just normal petrol with additives if i am right. Any suggestions on this friends

Re: KTM 200 Duke


It would be unfair if we said top end hasn't changed. While the bottom end and mid range is stronger now, we did not get ample opportunity to test the top end.

First being the weather conditions, air is cold hence dense, roads are wet, and too much winds on open roads. Second, it reaches 120-125 pretty quick, however anything above that is uncomfortable due to the wind blast.

Hence, for the top end, we got to wait for favourable conditions.

Regarding heating issues, I too faced heating issue until yesterday. However, a visit to the service centre and Oil and filter change took care of that. Today after riding extensively did not find any overheating.

Also, Abhishek had mentioned bike would take some time to work with the new ECU.

Another piece of information, service centre guys said a pair of Metzelers would cost 11k from them, while same woul cost 25k outside as Bajaj purchases in bulk. Stock D200 tires cost 7k.

Re: KTM 200 Duke

That is some good news bro, you just made my night.
And there is this question eating my head since long. If the kiirus people say that the speed is locked by the speedo console and not the ecu then if the console is disconnected the bike would either not start or the top end restriction won't be there.
Somehow I am not able to digest the fact that a speedo can restrict the speed if we already have an ecu for the same.
If they fiddle with the speedo and somehow your bike starts hitting more in terms of top speed, I would doubt that they just fiddled with the calibration and induced an error.
Fyi, I have done a 142-43kmph on a stock 1st lot duke. 42T rear and 1st lot ecu mapping(the limiter kicks in at 10.5k rpm in 6th).

Re: KTM 200 Duke

I had a feeling that some more air was missing in top end, esp past 10,000 rpm (now the rev limiter is at some 11,650 rpm), not so much in low and mid. But we can know only if we try another air filter like BMC.
I'll call the Motozone guys tomorrow and check with them what is their feedback about BMC filter with and without ECU remap, and whether it is worth getting the BMC filter.

The peak power is technically at 10k rpm, however, with remaped ECU you have more revs now, upto 11,650 rpm. So, even if the top is the same (which we are STILL not sure because we couldn't test the top properly because of wind, so please hold off with the top power conclusions until we test it more in better conditions) it goes further all the way to 11,600 rpm. In some bikes the power line drops considerably after the peak power rpm, but that's not what I noticed - it felt it's holding the same power until 11,650 rpm. Which means you can add 10% more to any top speed if you're on stock sprocket. I am not sure the bike would be able to reach 11,600 rpm in 6th gear with 39T sprocket (which would theoretically be over 165 kmh).
But we all saw that video where Duke can reach 168 kmh. That was with air filter completely removed, so maybe the BMC filter might help considerably in top speed.

Anyway, I don't think you can say the top hasn't been changed. Even if it hasn't - you have 10% more of top end, which is definitely a considerable improvement!
But, I had a little higher top speed (without reaching the rev limiter) with Kiirus ECU than with stock when going in very similar windy conditions - 118 kmh vs 127 kmh. That alone would mean the top IS stronger with Kiirus ECU. But I'd rather wait with top end conclusions till we do some more accurate tests with the top end.

BTW, can you comment on the acceleration of stock sprocket vs 39T?
Is it a big difference?
Does the bike accelerate much slower or just little bit? Or pretty much similar as with stock sprocket, but just "feels" it accelerates slower?

I think all petrol is RON91, but premium has cleansing additives which help to keep the petrol clean.
I've noticed the bike runs little smoother in low revs with premium, but that's the only difference.
I use regular petrol since premium isn't available in my area. But the guys in service center said my fuel filter was very dirty, so you might want to check the fuel filter at every service, and if needed replace it. That's what I plan doing...

@Doga - My heating problems started after I left my bike for 2 months with half tank of petrol (I know it's not good but I left in a rush). Which again makes me believe that some slight damage happened to FI or somewhere there. My fuel meter also became wonky, sometimes would start showing I'm on reserve whereas the tank was full or half. I never had such problems before. I don't know if FI and fuel meter are connected, but something is not right.
At next service next week I'll change to Motul 300V, and see how that affects the engine and heating.
But, I'll still want to fix the problem, even if I have to change the FI.

@chinmayakar - you might want to share that info about Metzelers in D390 thread, I think you'll make many people happy.
If that is true I'll for sure switch to Metz when my MRFs are finished.

I talked about it with both Abhishek from Kiirus and Vikram from Motozone. They both said the same thing - there's a chip inside the speedo which tells the ECU to cut the power if the top speed is reached. Different speedos (from different lots of bikes) have different limits.
The way to bypass this limitation is to disconnect the cable from the front wheel that goes to the console and measures the speed. The console would work, but only the speed would not be shown. That way the chip in the speedo wouldn't tell the ECU to cut the power. However, the only way to check the speed would be with GPS.
Disconnecting a speed cable isn't really an option for anyone, so the only way to get rid of that limiter is to rewire that chip inside the console. Motozone guys said they do that for Rs 1000 if a speedo is sent to them.

For example, my August 2012 Duke was cutting off at 136/137 kmh with the old map that had the rev limiter at 10,500 rpm in all gears. Which points to the fact that something else than ECU was cutting the power off (which would cut the power at 139 kmh).
I am not completely sure (I was maxing the engine at 136 kmh, it was windy), but I think it cut the power again at the same speed with Kiirus ECU few days ago.

I'll first change to 40T sprocket and test the top speed with it, and if it cuts off at that speed then I'll be looking to rewire that limiter one way or the other.
A really low kick by KTM to add such a top speed limiter, btw!!!

Re: KTM 200 Duke

[MENTION=18379]splus[/MENTION], did u get the windscreen? HOw muh did it cost you? Can you please post the link. Also, do give your feedback if the screen serves its purpose or is more of a hindrance.

Re: KTM 200 Duke

Its not your FUEL Injector Guys..Its the fuel pump you need to replace which is in the tank..me and my friend had the same problem ..and got it fixed the power feels new like before.another problem and replace with the duke parts is the fuel pump which is to be changed every 12k KMs

Re: KTM 200 Duke

Anyone used both Motul 7100 and 300V on their Duke's ?

Want to know the comparative difference between the both on the duke !!

Re: KTM 200 Duke

It arrived to my friend's address in Bangalore JUST after I left. I'll be back in Bangalore on Thu, and then I'll put it up and check it out. [MENTION=32641]shv18[/MENTION] has posted an instructional video few pages ago, how to mount that windscreen. It's very simple, especially if you keep some parts already mounted to the windscreen. It seems like the first time would take some 15 min to set up, but every other time would be in 5 min max.

It's MRA RNB (for Racing Naked Bike) windscreen, smoke grey color, and it's exactly Rs 8k, shipping included.
Price is on a higher side, but with euro at 81 Rs it's understandable. It's imported MRA windscreen (German company, best windscreens worldwide), made of special unscratchable and unbreakable material, that is also UV and chemical (petrol, alcohol, etc.) resistant. Of course, I won't try to test this.

Windscreen dimensions are 38.5 cm (H) x 36.5 cm (W).

Here's few photos of the mounting parts with the windscreen:





Edit: as you can maybe guess, one can adjust the angle and position of the screen to be lower or higher. Should be very customizable.

Wow, thanks for this info!
Was your bike also heating up more?

Actually, now that you say, I think the noise of the fuel pump had increased as well compared to before.

Ok, I guess it's the fuel pump that'll get replaced then!

Re: KTM 200 Duke

Used both of them, earlier the duke was running on 7100, 1k kms back gave it some 300v. First thing I noticed was the bike runs a little cooler, even the engine note is a little muted in comparison. Some improvement in terms of vibes.(was already very smooth)
The difference in performance is not much noticeable as of now. Lets see how long the 300v lasts. The 7100 was drained after 4k kms.

Re: KTM 200 Duke


Good you brought this point. I have read 300V is double ester and is known to cause oil leakage. In Duke's case, you may find traces of coolant in the oil. Anybody using 300V for a while has experienced this?

Re: KTM 200 Duke

That was the case with the older Pulsars. Duke's should have better metallurgy & gaskets!

Re: KTM 200 Duke


600 cc bikes too face this issue. Owners on Online forums for 600 cc bikes too faced this issue, and 300V is recommend for high end bikes. I tried to google before I finally decided on 7100. The reason what I could make out was, 300 V in comparison to 7100 is double ester, hence the additives (may be wrong term) that is used in it needs engine packing to be very tight. It easily seeps out of minute openings, where other oils especially 7100 wont seep out.

Re: KTM 200 Duke

I guess depends on an engine...
Just curious, do you remember which particular 600cc bikes were affected?
Those with higher revving engines or with lower revving ones? Or just random...

I'd assume that higher revving engines have tighter parts, but that doesn't have to be the case.

If there are no reports of Duke being affected with this issue then I'll go for 300V anyway.

Re: KTM 200 Duke


I don't remember the model, but yes it was Suzuki. I know you will, but still I would recommend you to search, and you will know what I am trying to say.

Yes, you are right, with high revving bikes packing should be tight, but, I have seen cases at Service Centre where coolant had found a way to mix with the oil, that was on 7100.

Hence, I have my reservations with this oil. Anyways, it is good if people have been using 300V for more than 25K KMs without any issues. Anybody here who is using 300 V for that long?

Re: KTM 200 Duke

Now you are scaring me, friend would kill me if anything leaks.
But then I have used 300v on my old model p200 without facing any leakage issues. Used it for more than 10k kms.
Once I was not able to source 300v for the p200 and had to fill in some crappy castrol ss, after riding for some 1k km noticed some oil leaking from the head.

Immediately I switched back to 300v and all was fine. All this when people say that the pulsars had leakage issues if you use 300v.

I guess the duke should be fine.
