Ethanol, like all alcohols, does indeed have very high detonation resistance, and so has a high equivalent octane value. Unfortunately, it also has a rather low energy content, so you need to run it much richer than gasoline to get any power out of it. When used straight as a racing fuel, its biggest advantage is from the extremely high compression ratios and/or supercharger boost levels that can be run with it, rather than an increase in thermal energy in the fuel itself.
The reason it's in pump gas is to increase the amount of oxygen in the fuel in order to try to get a more thorough burn of the very lean mixtures run by modern automobiles. If you're looking for something to increase performance in your bike, I would not only look somewhere else, I'd avoid that fuel altogether.

as for mixing your own you would need pure ethanol. mixing might not be that safe. also you don't know what other additives are in there make it all work
any one know if ethanol is bad for the motor?

Speedway uses methanol not ethanol and you have to clean out your carb after every
meeting because it turns to jelly. My old man races formula 500's (mini sprintcars) and
they run methanol. He has to tear down the motor every few meetings too.
