I ran C12 (108 octane) last year with 13:1 compresion ratio and you could eat out of the megaphone it burns that clean. If you are doing a track day try a can of U4 (Ultimate 4-stroke) just for the fun it. You will notice the difference in performance. It comes in steel cans so it keeps.

(stephanie i don’t think many of us guys have knitting needles to run some sound comparison tests with - can we borrow some?)
But i really like the added performance of the higher octane -- trust me it works
Nothing more thrilling than running the morning at our track days with regular premium then filling up with race fuel at lunch and seeing an extra 15km/hr on back straights and more pull out of corners.
Splurge and enjoy the extra power when ever you can!

Seems to me that we're not really choosing a specific octane number - only deciding between 'Good, Better & Best'. What I was hoping for was a 'REAL Octane Number', like they are required to show on the pumps in Europe, so I'd know for sure what should go into my bike.
Why can't we have that here ? European standards too constrictive for the North American fuel companies to meet ? Or like the Metric system, someone deciding for us that our way is better and we don't need the Europeans to tell us how to rate our gasoline. How about some truth in advertising
what a concept 
it would never fly here
