Re: KTM 200 Duke

eh. D200 hitting 160 KMPH?!?!?! RC struggles to hit 135 (on the speedo) and slows down.. wow.. more speed won't hurt more.. :P

Re: KTM 200 Duke

Will require modifications but hitting those speeds is quite possible. I remember my little 200 hitting 151kmph on a regular basis and this was without a remap. It did have some serious work on the head and clutch basket though

Re: KTM 200 Duke


stock d200 hitting 151 ? or polished head / air flow geometry changed for valves ?
please assist on the work done. would love to learn further.

Re: KTM 200 Duke

Check one of my old posts, I made a list of all modifications on the bike. Or let me look for it...

Re: KTM 200 Duke

Yes, even I am wondering how is that even possible on a stock and new duke. RCs, touch 127 and the speed limiter kicks in. It has become very annoying nowadays, keep watching the speedo and let couple of RPMs to fall to escape the vague limiter which stop the speed very abruptly. Ajay, how you are doing 135, haven't you experienced speed limiter?

I think we should have this discussion on RC thread.

Re: KTM 200 Duke

I have a D390 and the engine braking is massive, it becomes difficult to have smooth on-off throttle transitions. I'd be grateful if you'd let me know what revision you did to the throttle body springs.

Re: KTM 200 Duke

For the D390 I would suggest Dhaval's quick throttle clamp, it reduces the play and does away with the rough on off throttle positions. It basically reduces the throttle play from 4-5mm to about 1.5mm

Re: KTM 200 Duke

Yeah.. Well.. 137 is the speedo and at that level it's the 6th speed almost at red line... That's it.. That's when the limit kicks in.. Maybe a different map on ecu for you?? Maybe KTM changed the map in there newer models???

Re: KTM 200 Duke

That is perfectly normal top speed for the 200. [MENTION=73103]joe_marvy[/MENTION] - i've seen the speedo indicate 137 for a second or two and drops down to 135kmph.. this is on my bone stock d200.
From what i understand, the ktm's somehow regulate the speed and prevent it from going beyond 137 (say even if you have done various mods to enhance top speed). I think you need to play with the electrical/electronics to be able to cross 137 kmph on a D200. No?

The 2015 duke (the one with the slipper clutch) already comes with a revised throttle setup (at the controls not the throttle body). you have to get used to the engine braking man. A quick throttle is only going to make it more 'racy' every time you get off the line and is not going to help with reduce engine braking (in fact might make engine braking more pronounced since you are opening/closing 'more' of throttle for every twist when compared to stock)

----consecutive posts auto-merged-----

127!? noway man.. maybe you are having clutch slip. you should be able to touch 135~137 on the speedo.

PS: am not encouraging anyone to ride at these speeds, but just stating the capabilities of the bike from what i have experienced. Ride wisely

Re: KTM 200 Duke

The cut off is for the Rpm not the speed... Having run the KIIRUS remap as well as the stock ecu with mechanical mods, it is possible to get past the 137kmph mark pretty easy.

As for the revised throttle on the slipper D390, the throttle is the same but the fuelling has been revised. Different maps. We know this because we swapped ECUs, if you haven't used Dhaval's throttle setup, refrain from commenting.

Re: KTM 200 Duke

yes, i know the rpm has a cut off.. but I remember reading somewhere that the speed was also limited. I might have been wrong.

i haven't used dhaval's quick throttle setup, but i have ridden few bikes like the Rx100's , 135's (no engine braking on two strokes), pulsar's ,cbz with a quick throttle way before these ktm's made their presence on planet earth. so relax and refrain from asking me to refrain from commenting.. this is an open forum and be open to discussions.
and dhaval's quick throttle is just another mechanical quick throttle no different from the ones that I have used on other bikes. And the guy was asking about ways to reduce engine braking and your solution was to use a quick throttle ? Do you know that the quick throttle makes things more snappy and isn't going to help with reducing engine braking.


PS: I have nothing against mr.dhaval or his quick throttle contraption, its just that its purpose is different. I for one use another such contraption from his stable.

Re: KTM 200 Duke

The choppy throttle on the D390 is because of the excessive play in the throttle grips, Dhaval's 'contraption' helps in an easier on/off transition making the engine braking less apparent.

Engine braking is more pronounced when there is a huge difference in the fuel going into the engine during open/close transitions. One option is to mess with the AFR which is what most of the remaps do, the reason there is a drop my mileage when you ride hard on a remap. The second option is to mess with the throttle body springs, which is what I did, the springs have better tensile properties and allow for a smoother roll off reducing engine braking aiding in faster corner entry. I only did this because of the amount I tracked the bike.

The reason I recommended Dhaval's quick throttle is because I have used it on a D390 and I know the massive difference it makes, it's doesn't make the bike jumpy buy does it make it way more responsive

Re: KTM 200 Duke


So yes, there seems to be some sort of a speed limiter and i remember reading about this at a few other sources.
another discussion on this speed limiter topic: http://www.xbhp.com/talkies/motorcyc...-duke-733.html

Re: KTM 200 Duke

A little history, the initial Duke 200s sold used to hit the Rev limiter even in the 6th gear and we used to top out at 141-143kmph before the Rev limiter kicked in, this was the limiter bouncing off at 10.5k... So to solve the issue they remapped all the ECUs in a very unofficial recall, calling it routine free service. The speed dropped to 132-133kmph with the 43 tooth sprocket, most of us went up in arms because of the drastic drop in top speed, though now the remap didn't allow the Rev limiter to be reached in 6th, this wasn't a speed limiter but rather a Rpm limiter. They dropped the rear sprocket by a tooth and hence we now have the 42 tooth sprockets this allowed the top speed to inch it's way back to the 135-137kmph mark.

Now again, if you ask me how I know this, 2 things, owners experience and dyno runs...

Re: KTM 200 Duke

I second this. First lot 200 owner, have hit 140/141 on numerous occasions on that raunchy hot stock map.
