gov.uk E10 checker says:

"All Honda motorcycles and mopeds produced for the EU market since 1993 can use ethanol-blended gasoline up to 10% although carburettor-equipped models could experience poor driveability in cold weather conditions."

I suspect that's because many other countries have been using E10 for years so they probably made them compatible ages ago.

All I would suggest is that if you use E10 then don't leave it sitting with a tank of the stuff over winter as Ethonol absorbs a certain amount of water (and at around 0.5% it separates out). Maybe run it down to half a tank and stick some Esso Synergy supreme+ 99 in as a top up pre-winter. All assuming you don't use it over winter of course.

My understanding is similar fella! FI bikes should be much less affected compared to carb'd bikes, hence I am looking at a CBF. This would be a replacement for my old GS500e which now really needs super unleaded all the time as I don't want to risk any problems with this new E10 stuff.

Honda says its OK, so carry on. You can still get E5 petrol in UK - it's the 97 RON stuff. It costs more than the 95 but you get better running ("We need more power, Igor") and more MPG after a few tankfuls , so the cost differential ends up very small. Different companies call it different names such as "Super Unleaded", "City Super", PowerPlus", "Save the Planet Unleaded", "Makes your penis Larger Supa".......

It isn't really about the running, there's even suggestions that the Ethanol has a higher octane rating than the petrol it is mixed with.
It is about the emissions (CO polution).

The issues are elsewhere, stuff you don't see, know or think about.  The collapsing plastic tanks, failing inlet rubbers, reactions with brass carb components etc.  None of these things happen instantly but are affected (to some degree or other) over time. 
Okay, Honda say the biffers are safe, so that's all we can go on (but they were, originally, deemed safe on E5 - I don't think everything has been retested).

Over winter storage could be a concern and the general advice seems to fill up with E0 if you can (or E5 if you must) - or go to adding other chemicals in.  Personally I've always stored mine for winter filled with super unleaded; never had an issue so far (on E5) and always managed to start it without flooding issues first time after.

Only do it right - no bodging please.   Keeper of the failed stator list.   John.

+1 any failings caused by the use of E10 will be gradual to parts we don't normally see.

E10 mileage is now at 2,500 miles and still no NOTICEABLE difference
