Normal Petrol have RON 91 in India except for a brand whose name I cannot remember (it has RON 89). Bharat Petroleum's Speed is also RON 91 but with additives that help in keeping the "system clean". Now, it is of no use to have Petrol with octane higher than 91 in Duke 200 as its compression ratio is around 11.3:1. Basically, Speed 93 and Speed 97 are useless for Duke 200. (Speed 93 will be good for Duke 390 tho as its compression ratio is above 12:1)

Also, it is of "absolutely" no use to fill your tanks with Speed (just a waste of money). It would be sufficient to use normal RON 91 petrol. However, you may get it filled with Speed once in a month or two just to "clean the system".

Rest all features (like Smoother engine, better pickup etc.) of Speed (BP), Extra Premium(IOC) and Power(HP) are all marketing gimmicks.

P.S.: These are my views based on my findings and discussions with "experts". Still you can curse me if you want to. :P

Update:
Bikes that are in Run in period (New bikes) are recommended to use Premium petrol like Speed. After run in period you may change to normal fuel. (But RON 91, and not 89)

I was honest in admitting the truth and frankly I all I could expect was brickbats here . I agree. There is no running away from the fact that I did a stupid thing and in hindsight that stupid thing could very well have turned into a fatal thing for me or for someone else. Though I was hardly doing 20 and did not hit an oncoming vehicle(I actually hit a person just trying to ride his bike out of parking from blind spot because my line of sight was blocked by a huge SUV), it could have been a lot worse. Fact is I in general abide by the traffic rules and this was a very rare occurrence when I did it. I should learn my lesson and not repeat it.
But one thing I'd like to add. Sometimes people,although totally right in voicing their outrage, become a bit too preachy and in not a very friendly way. Ok sir I am nincompoop/moron/'jeopardizer' and what not but tell me one thing here guys: Which is the race track people go to for testing the limits of their machines and report routinely here on this forum about the rev limiter of the duke cutting in sharply at 137/138 , about the Ninja's prowess at high rpms or about the CBRs long legged manners on the streets/highways? I'd like to go to that track too to crash my bike and hit some innocent bystanders or some other rider.
Even if the argument is that the stretch which was used to test it is a desolate road with sparse traffic, there is always a chance that some slum dweller just decides to jump on the road after having relieved himself in the bushes. Who would be the moron then? The rider? The jaywalker? or Both?
Truth is almost all of us act stupid and break some kind of traffic rule once in a while. Speed limits are the most common ones. Entering a wrong lane was recipe for disaster and the guy who paid for his stupidity was me that day and I would try my best to abide by the rules from now on. But I just hoped people would be a bit milder here.(though some guys did show their soft spots I'd agree )

Got mine serviced yesterday. And the chainset was replaced. Total bill was around 5025rs.Its quite fascinating about the chain going off around some odd 11000kms. My friend had his bike's changed at around 11-12k kms.

The cut off in 6th gear in the original first ECU map was at 137-138 kmh and it was quite strong and sudden.
The cut off in new (5 months old) ECU map is at 133-134 kmh and is soft and gentle.
At least in my bike...

You might want to check with KTM which ECU map you have (sounds like the old one) and decide if you want to ask them to flash the new one or not.
The new map locks the revs in 5th and 6th gears at 10,000 rpm (leaves it at 10,500 rpm in other gears), so it reduces the top speed but not by much, and smoothens the power delivery at low revs, it's less jerky.

Or you could go with Kiirus or Race Dynamics' modified ECU and increase the rev limiter to 11,700 rpm and top speed at 149 kmh, with boosted power esp in mid range...

What's the minimum fuel efficiency you guys have seen on the console yet? I saw 17 km/L yesterday. That's as low as i have ever gone.

My worst mileage so far has been 37 kml when I ride @ 125 kmph @ 9000 rpm on NICE road & best has been 65 kmpl .......

Are you F***'in kidding me! 37 kmpl is one of my best mileages. But 65 kmpl is ridiculous! Are sure about the figures?

Hey, thanks for the reply buddy.

I saw the bike hit 137 and a sec latter it hit the rev limiter. So am guessing it kicked in at 138kmph. I bought the bike on Nov 26th and was told that all the old problem have been rectified and mine was from the new lot. I doubt it coz, the rear shock was replaced last week under warranty. Paint was chipping off, as far as i remember that problem existed only in the older lot.

Any reviews on Kiirus or Race Dynamics modified ECU?

But thanks to KTM it could take so much beating and being lightweight it just kept running tilted and I could pick it up straight (due to my standing position). It would have been really fatal if bike had fallen and I would have been thrown on road with speeding traffic. The vehicles behind me did see what happened and I just couldn't stop myself and sped off from there all trembling.

I am sure if it would have been any other bike, I might not have been writing this post. It was just plain stupid of me. And whatever be the case, I might not be able to speed up on that road again. For those who are from Mumbai, it was the JVLR road going towards Powai just after crossing L&T.

Got my self the duke 200 yesterday purchased it from the showroom at phoenix compound (lower parel).And Boy does it acclerate in a flash. It just keeps going. Although i read everywhere that it has rev limter at 7500 rpm but my bike just went on goin to 85 and upward's i thought rpm imiter would kick in but it seem's it doesnt have a limter. So i slowed down and kept riding at 40-50. when i reached home i see the heat bar almost all the way up some warning signal's flashing, i could smell something burnt, like oil or may be it was just the heated up exhaust and other components. So my question is should i hv a limiter on or not, the showroom sales guy said yesterday that it has a limiter till 1st svc, but the mechanic told me today that it does'nt. Also when excatly does the radiator fan start spinning? and is there anyway to know if the coolant is being circulated properly?

This pic was taken a little later after i stopped, the heat indicator was even higher than in the pic, but not all the way up i guess.

Hey,

All the new dukes are limited to 7500 rpm till 1st service. No exceptions. The bike does around 90 or so (I havent tested it at that speed yet) at 7500 rpm. Next time you take it up, try checking what the tacho is saying instead of the speed. That'll probably clear your doubt.

The heat is normal, as long as it stays within the big segment as indicated on the MID. Dont worry about it, since the bike is new, components are running in, hence more friction, hence more heat. It will settle down over time. The fan comes on as soon as you reach the higher end of the segment and will bring it down by a few degrees.

Enjoy your bike and welcome to the club

And i guess heat it not really a big issue untill the bar goes all the way up to maximum? is that correct?

Although i read everywhere that it has rev limter at 7500 rpm but my bike just went on goin to 85 and upward's i thought rpm imiter would kick in but it seem's it doesnt have a limter.

Rev-limiter comes into play only at 10.5K RPM in the first four gears & at 10K RPM in the remaining two gears. Heat is normal, nothing to worry about as long as the fan kicks-in & there is no 'High Temperature' warning message in the MID.
