Well to ressurrect an old thread, i was reading the manual for the MT09 today (come on, how many of us have bothered to?!) as i needed to adjust the clock, and section 3-19 says:
Recommended Fuel: Premium Unleaded gasoline (gasohol -E10 acceptable)
"Your Yamaha engine has been designed to use premium unleaded gasoline with a research number of 95 or higher. if knocking or pinging occurs use gasoline of a different brand, use of unleaded fuel will extend spark plug life and reduce maintenance costs.
Gasohol:
there are two types of gasohol, those containing Ethanol and those containing Methanol, Gasohol containing Ethanol can be used if the Ethanol content does not exceed 10% (E10) Gasohol containing Methanol is not recommended by Yamaha as it can cause damage to the fuel system."
So as long as it's decent quality 95RON it's unlikely to make any difference.
Personally I'll always avoid supermarket cheapo stuff in the bike or any cars as i've been told by two different RAC mechanics, my local mechanic - who i trust, and my colleague who's into tuning and remapping that it's cheap because it's 'watered down' (not with water i suspect!) and doesn't have the proper cleaning/lubricating chemicals in it.
HTH
