    I heard petrol works pretty well :D

    On a more serious note, if you're talking about say 95 vs 98 petrol then it's not going to make a big difference at all, not on a 125 at least, as long as you don't use diesel you'll be just fine for a very very long time :p

    yep, the difference will be tiny, but also bear in mind that lots of tiny differences add up to a faster bike.

    Higher octane (MON/RON) = more bang. Better fuel is one of the easiest ways of getting more power - e.g. race fuel, avgas, nitromethane.

    Also afaik the mon/ron rating affects mostly high compression engines (since that number is also about how much compression the fuel can handle without detonating) and bike engines are/(were?) generally higher compression than cars so potentially better fuel would have more of an effect than on an equivalent "entry level" type car.

    Still, multiply by a tiny engine and you still got fk all but it's fun ;)

    Mine gets whatever has the highest number, usually BP ultimate or Shell Vpower, esp as a tank full is still less than £15 xD
