Hi!

In Estonia we have 95 and 98, not the same than in US. This year 95 changed and the new one, 95E10 has 10% biocomponents.

You shouldn’t drive some old cars with this petrol. What about our motorcycles? Should be fine, I don’t know much about fuels.
 
I get the highest grade I can get. Usually its 91 or 93 octane. Our gas in the States usually contains 10% ethanol too. Never had issues except when it comes to storage, and the shelf life of the gas is terrible.

Most of my bikes life, it has had the original 360cc engine, which has slightly more compression than the 400s do. I use the same gas with the 400cc.
 
Ethanol and bio Mass that causes water rust (ethanol) are the enemy, not the grade of gasoline. Premium is generally a waste unless ethanol free
