The Chennai PBK was flooded with dukes, as Shubz stated the play in the foot pegs I checked a couple of bikes and all of them had the play. So, putting a washer will fix it, I guess.

nice meeting u too!...

So, even i am starting to loose my patience here

... Booked it 8 days back (24-2-12) @ chennai KTM, so any idea when i might get mine delivered ;-)

I get pissed when i see all those cbrs and r15s cruising down the lane next to my house :| want mine asap ;-) ;-)

I put SHELL normal, it was actually a mistake but it has posed no problem after 80kms.

This is exactly the info I needed

So that's a good thing. When you ride out of the city, all you need to do is some planning and you won't have much trouble.

Hey people who have booked on 11th Feb have not received it yet.

Was one of the first people to have the test drive as soon as bike came to the adyar showroom.

Fuel Octane Rating

I had a discussion with BPCL's Delhi sales manager. He had the following things to say -
1. Nowadays, Octane rating of all kind of fuels is more than 90.
2. Unleaded Petrol ~ 91 Octane Number
3. Speed ~ 93 Octane Number (with additives that remove carbon from the engine which is deposited because of incomplete combustion)
4. Speed 97 = 97 Octane Number

So if there is no adulteration by the filling stations, there wont be any issue in using the unleaded petrol. But to be on a safer side, its better to go with Speed!

Ride Safe!

What petrol is required as per the manual? 91 Octane? Because if that is the case, Normal petrol is alright. No need for premium petrol. Actually Premium petrol is not required on most engines as long as they do not have lean burn / direct injection / stratified injection. Those are the engines where you can feel the difference (both in Power and FE) due to premium fuel.

With the right cam and correct timings, a manufacturer can easily run a 11.5:1 compression ratio engine on regular 91 Octane. Yamaha runs the FZ1 on a 11.5:1 compression ratio engine and its manual clearly mentions that it will run well on 87 octane.

So, I *hope* Bajaj/KTM is not stupid enough to recommend 95 octane on a *relatively* mass market street bike. However premium it may feel, it is not more premium than a liter class bike.

Agreed. I think KTM/ Bajaj wants to be on a safer side with the initial bikes. Dont know the rating specified in the manual as i havn't received mine yet. Rest u know with Emission norms coming up in 2014 & 2016, (BS 4 & BS 5) the fuel will be much better.

93 + additives or 91 + additives = 93? Which one?

If I'm not wrong, its 95 RON mentioned.

Not quite really; higher RON is required to avoid pre-ignition & certainly not that 95 & 91 makes a huge difference, but, higher RON gives a noticeably smoother combustion than 91. I've experienced it on CBR (10.7:1) & fellow xBhpian experienced it on GS1200.

Its 93 + additives. (Additives wont add to the octane rating)
& yes. More the octane number, better the combustion & smoother the ride!

My friend, who in India makes 93 RON

? The highest RON rated Petrol is available from BPCL, a.k.a Speed 97

Exactly my point & that's what the manufacturers also recommend on a higher CR engine.

Normal Petrol is RON 91 (Both BS3 and BS4)

Premium Petrol is RON 95 (Both BS3 and BS4) So maybe the additive they are using is an octane booster.

Speed 97 was discontinued in April 2010 AFAIR when BS4 came into existence(From what i remember, sale in Pune has been stopped quite a while back.) purely because it didn't make any sense if RON 95 is so widely available.

So it seems BAL/KTM are not as smart as I thought they were. If thats the case, better stick to premium fuel on the Duke. Just reconfirmed it on the xBHP review, it is in fact RON 95.

Of course what you wrote is true. Thats why I wrote a manufacturer *can* adjust timings and cams for lower RONs. That doesn't mean they always will. Apparently Yamaha did, KTM did not.

I'm aware my friend

Originally posted by antz.bin View Post

Which premium Petrol & available where? SHELL has premium one, both rated at 91 RON, just that they've some additives like corrosion resistant & few others (when I first heard, sounded like rip off RG!!!). So who makes this? Pls share, I can probably use this as good alternative to fuel my CBR than the regular 91 RON & high priced 97 RON.

It is very well available, atleast, here in Chennai & Pondicherry (verified 2 weeks ago when we were there for a BFast ride) & I usually fill Speed 97 after every service as BPCL is close to HMSI ASC. I'll get this also confirmed this weekend or next. The last I filled Speed 97 was Nov 2011

95 RON? Where? Which PSU/Private makes it?

No no!!! Its not that simple as it sounds; I highly doubt if FZ1 comes with adjustable timing; I know for sure GS1200 & few other BMW motorcycles have it as its not only expensive, but, complex technology. Probably Niks can confirm from his owner's manual.

Sorry about the OT & I stop it here

**mid** · 03-04-2012, 03:38 PM

as far as i kno, there is no 95 ron petrol, normal speed and extra premium comes with same ron numbers as ordinary petron but with additives like friction busters & cleaning agents. speed 97 is the only high octane fuel, its still there, aint it?
may be the premium fuel is less adulterated :P

**Rajathslr** · 03-04-2012, 04:04 PM

May day...may day...

Folks need some interactive discussion, I bet this is going to be the most DECISIVE factor of the DUKE 200...

I made up my mind to test the FE of my Baby Duke today, filled the tank full with Shell Super high octane petrol, set the trip1 meter to zero, headed out to the nelamangala elevated highway(Bangalore).

Bright sunny day, Supersmooth highway, no much traffic...I rode consistently at 70kmph for the next 22kms, then had to switch to a 6 lane Bangalore-Mangalore highway, increased the speed to around 78kmph and managed to reach a top speed of 94kmph at a slope only once & I dint stress the engine at any point during the journey (max 6k RPM)

After 60kms, i took a break for ten mins, then headed back non stop in the same pace to the same gas station and to the same attendant..

Total kms : 101.2
Total litres :

(

)

Please try your best to guess the Mileage I got....(each wil get 2 chances)
