may be a little more performance, probably negligible since these are high-performance bikes anyway. if you get race or higher octane aviation fuel, the difference is somewhat noticeable.

as far as mileage go, I get about 10-15 miles extra per tank if I use premium regardless of riding style. all my riding has been on the street, so I could expect a little better on the freeway.

bwahahaha!

I know that cars use higher octane fuel when they have more advanced timing, higher compression, and/or forced induction. higher octane fuel is harder to ignite and thus burns slower. which makes me laugh at the ricers in their civics with 91 octane stickers on their gas lid, when they have relatively stock engines. higher octane in an engine designed for 87 will not make more power, it would more likely hurt performance.

basically it comes down to what the bike's engineers say, i.e. in the owners manual. but if it runs fine on 87 and doesnt ping(detonate, knock etc.), then run 87

I always thought that too. 2 weeks ago when the gas price skyrocketed, I started putting 87 in my bike. I noticed a SEVERE power increase. I wish I had the money for a few dyno pulls so I had the proof on paper. I couldnt believe it... it goes against everything I was taught.

believe it or not, this is also natural when you switch back and forth after a while. though I didn't notice it when I switched on the bike, but it was apparent on my car. but as your power increase, expect your mileage to go down using regular.

Basically it's different for every bike. Some do better with the high grade, some do better with the low grade. Your bike can run on any grade that doesn't cause knocking/pinging. Personally I go for the cheapest stuff I can. Sure, I might get 1-2 more ponies out of the higher grades (then again, I may get a 1-2 hp loss too), but regardless, who can actually notice a few hp on normal street riding? 90+% of us can't tap 75% (probably more like 50%) of the performance our bikes are capable of, and we're worried about a couple of horsepower? :huh:

I run 87 octane in my bike and I do fine. In fact it runs a little better than premium. Just don't put diesel in it....lol

Spicer's right...you won't be able to notice anything anyway.
