Make sure you are reading both your manual and the rating on the pumps correctly. America and Europe use different ratings. In America, our manual says to use 86 or higher octane. I know Europe uses a different standard, and your post relfects that with the "research octane rating". We use "on the pump" rating, which are different. Granted you are in UAE, so the I can't say what standard applies for you.

 

Heh heh heh

 

Ok so i cant find my manuel. so can someone with an 05 600RR tell me what the recommended octain is. I have been using 91 (premium here) but if the manual only says 87 then im going to swtich. THanks

Just out of curiosity, about 15 yrs ago I had a 71 camaro SS that I ran 500hp with, 13:1 pistons, dual half inch feeds into a holley 750 cfm double pump. Yes 4 miles to the gallon. Anyways when I would pull up to the racing fuels station the gas in the pump was leaded, I guess my statement would be to those who are using the hot stuff at the pump that you are making sure its not leaded. I know you can buy race fuel in the 55 gallon drum from race fuel companies(not that I would). Just so you all are aware of the possible complications to your fuel system.

 

I saw an article one time about this debate.
Their test bike, which was a ~2001 R6 actually made an
extra HP or 2 with 87 (recommended) over 93.

Interestingly, the 1000cc machine the tested showed less of a difference. They concluded it was because of the higher compression higher reving 600's that proper utilization of fuel was more important for max HP.

A more complete burn = more power.

Use what the bike calls for, don't just "give it the good stuff". You are not only spending more $$$, you are actually loosing (small amount) of Horsepower, and possibly leaving deposits from a less complete combustion process that in the long run could reduce performance even further. However, if you feel you or your riding buddy expert - is smarter and more educated on the matter then HONDA/Yamaha/Suzuki/Kawi and everyone else, go ahead... it's your bike.

Don't be a **** and assume higher is better etc, and don't believe that "Octane boosters" add HP. They don't, they add octane.

Also, look up the differences between "Octane" and "RON"

Also, you'll likly find that the number in your manual is different from the number on that sticker in your tail.

To the guys above: You are comparring a 2003 600rr to a 2006 600rr. It's possible (I'm too lazy to look) that Honda
may have raised the compression a bit and recommends a different fuel.

 

Different article, but still a good read:

http://www.rc51.org/fuel.htm

"In hours & hours of dyno testing & Powercommander map building several key points were discovered some we intentionally set out to test others just came about on their own:

1. Standard Race Fuel (VP C12, C14, Sunoco 104, 100LL AvGas even high octane pump gas 96 or 100) ran straight on a stock RC51 motor will actually lose horsepower."

"...sometimes by as much a 4-6hp"

 

NOT TRUE THE 05 CBR 600RR STATES 87 OR HIGHER LOOK IN THE QUIK REFERENCE

 

I havent been nearly as involved with bikes to date as I used to be cars. I did drag racing cars (1400 hp mustang)up until about two years ago where it got to the point where my wallet just had no more blood to bleed lol.
I was fortunate enough to have a friend who owned a speed shop with a dyno and we spent 100 bazillion hours on that thing. Anyway, before my last turbo combination, I was running a nos set up. On motor only, 13.5:1 compression the car lost 16 h.p by using 116 octane as opposed to 112.
Someone mentioned above you need to advance the timing in the engine to take full advantage of the increased octane and that is absolutely correct. On the flipside, since higher octane fuels burn slower, using a higher octane than is required is pretty much the equivelant of retarding your timing. Thats not only my oppinion, thats hours of dyno proven results.

 

OK I never did buy into the higher oct = higher perform. BUT what I have believed was that the Higher Oct. was a cleaner burning fuel so I've been using it for that fact... So maybe some of you can shed some light on this for me, Does 93 burn cleaner than 87 ????

 

Tre - I think that answers your question doesn't it? You make the call...
