Bugger! That is a bit of a blow; probably won't do much for its resale value either.

With classic cars there is now a supply of ethanol compatible parts, I don't know if the bike market is lucrative enough to support something similar

all hondas since 1993 made for the EU are compatable with e10, yet bikes with carbs might suffer poor running in vert cold temps, which is probably a bit of carb iceing.

Some bikes had carb heaters fitted maybe there is a kit?

Carb icing can be combatted another way, keep the throttle open

It also works great at cleaning the engine internals such as injector tips, pistons and valves. No need for fuel injection system cleaner additives.

Rather than a manufacturer simply listing whether or not a scooter is unsuitable when it comes to E10 I feel it would be more useful if they list the parts affected & possible solutions.

An example would be with the nylon petrol tanks that absorb water in the fuel causing them to swell; a simple inner coating may well be enough to solve this problem. Also with fuel lines sweling, fuel lines are fairly easy to replace, but only if we have some of idea of which fuel lines to replace them with (I replaced the fuel lines on my Guzzi & the new ones have the same problem as the old so need replacing again; yes, an easy job on a Guzzi, but more expense).

Declaring a whole scooter unfit for use with E10 is too simplistic when it's just a few £s worth of bits to fix, & about 3 hours worth of removing plastic panels to get to them.

It can also be the fuel pump seals and injector seals that are unsuitable. Although I've found most are ok now. But still some cars come with seals that need to be replaced first before E10 can be used long term.
