"Q: Can I use ethanol in my motorcycle?
A: The use of E10 is approved for use by major motorcycle manufacturers including Harley-Davidson, Honda, Kawasaki, Suzuki and Yamaha. Harley-Davidson goes so far as to recommend the use of renewable, clean air fuels such as E10 because of their environmental and performance benefits."
