Here’s some info that might prove useful:
MCN spoke to major bike brands back in 2013 when E10 was first introduced to find out what a switch to higher ethanol fuel would mean for them.
The least-affected brands were Yamaha, Triumph, Honda and BMW. Yamaha and Triumph both said that all models from 1990-on are compatible with E10, while Honda said everything post-1993 is compatible, although carburettor-equipped models could experience poor driveability in cold weather.
BMW said that all their models regardless of the year of manufacture can run on E10 fuel with no adverse effects.
Suzuki models made after 2002 are compatible with E10 and those made after 1992 might be but owners should seek advice.
Ducati said that their Multistrada 620 and 1000 models were not compatible with E10 fuel, with tanks known to expand or leak in markets with ethanol-rich fuel.
And Kawasaki said that models made from 2006-on would be ok on E10 but advised customers not to use the fuel in bikes that weren’t specifically approved.
Piaggio (who own Moto Guzzi and Aprilia) were the least E10-friendly manufacturer in 2012, saying that all motorbikes built before 2011 would not be compatible with the fuel.
