But......100 octane will not give your stock bike anymore power.
Oxygenated fuel is a different story.

As long as your bike doesn't have catalytic converters , the lead is not a big deal.
Most people don't realize , as the octane goes up , the fuel is harder to ignite.
Really cheap 87 octane is the most explosive fuel out there.
Each octane point you go , over and above what your engine needs , will make less power as it gets higher.
Automobile engines can usually use 87 octane , as they are water cooled and have better anti detonation abilities.
There is a point on air cooled engines where there is very little control of the maximum engine heat produced , so the manufacturer recommends a higher octane to prevent detonation at high temperatures.
If you only ran the bike where it was super cold all the time , you could go below the recommended octane and be safe.
Unless you have really high compression , the octane above 93 would be a waste of time in most vehicles on the street.
