As far as fuel economy vs octane.... there should be no difference on a bike, or a vehicle with an old-style ignition system.

On vehicles with a knock sensor, it is possible to get better MPG on higher octane fuels, because the ECU will retard the spark timing when it senses knocking, which reduces cylinder temperature/pressure... reduced knocking, but also reduces MPG.
