Because with a higher octane fuel you need to advance the ignition to get the optimum burn.
With a bike like the Gen1 you can't do that, that is unless you fit an ignition advancer unit.
So with the higher octane fuel the piston is further past TDC when the main burn or explosion occurs, so maybe that could make it feel smoother or better. But in reality the performance of your bike is, if anything, very slightly down. And I'd put good money on it all being in the head.
It's worth reading the article via the link that Mike posted. Note the use of language in the naming of grades. ie planting the concept that a higher grade fuel will be better for, or perform better in your motor when it simply won't, all it will do is cost you more money and make more cash for the oil company. Shell is just pushing this further.
We also know that modern bikes have had problems with high tech oils and bedding in, so just in case I might be minded to avoid a fuel that claims to be trying to coat my bores!
At the end of the day it's just more marketing bull. All modern fuels have to meet certain standards, all have detergents etc, and I'd bet if you strip yer bike engine doon, assuming you've changed the oil now and again, I'll bet you'll find it pretty darn clean in there.
Anyway filled up with 95 RON tonight, that's all I'll ever be putting in her. Can't even remember what brand our local filling station is selling, it's changed several times over the last few years.
