Pretty much this, yes. Road engines run in a fairly low state of tune and have no problems using E10 even though in some ways it's an "inferior" fuel. The only big thing to be aware of is that it does degrade in storage so if you're laying a bike up for a year or more it's a good idea to drain the E10 and put in a stable product like Aspen.

In a carb bike, three months max in my experience and that's E5

I’ve been running my old 70’s two strokes on E10 for at least a year with no issues and have equally just completed a 1000 mile trip in the US on a 1969 two stroke Yamaha using nothing but E10. The stuff seems to work just as well as E0 using std ign / carb settings. Maybe I’m living in a fool’s paradise but it seems fine to me. I can leave my 125 Suzuki for months with E10 in the carb and it still starts 1st / 2nd kick.

Clarification regarding fuel use in the 2020 Yamaha Tenere 700
From what I gather from comments on this site, ethanol is combined ( in Europe anyway, ) with unleaded fuel producing E10 95 Ron as a combination, as an example. When I checked the owners manual for the 2020 Yamaha Tenere 700, it indicated this combination of ethanol/Ron rated fuel is required in the bike, that is E10 95. I thought the information meant that EITHER E10 OR 95 could be used. It seemed an odd way to express it when I first read it. I am going to ride in Europe soon and would appreciate knowing if the fuel is combined as stated above. Here in Australia we have our ethanol fuels pumped SEPARATELY from our 91, 95 and 98 versions and so I am a bit confused with the terminology in the owners manual. Any help available? Can you readily fuel up with non-ethanol, unleaded 91, 95 or 98 in Europe?

The problem doesn't come from burning E10 in your motor. It comes from leaving it sitting in your carb and tank.
As long as you're riding, it will be fine. It does have less "bang" for your buck but with an old XT600 you probably won't notice a thing.
However, over the long term, E10 will perish your 0-rings, fuel pipe etc quicker than E5.
But any modern fuel line and quality carb rebuild kits will be absolutely fine with E10. Just don't buy sh*t from Ebay/China. Pay the money and buy genuine Yamaha rebuild kits. I know they're expensive, but it's cheaper in the long run because they will fit properly and last a long time.
And NEVER EVER EVER leave your bike sitting over winter with a tank and carb full of E10. You shouldn't even do this with E5. But with E10+ it's expecially important.

The ethanol is mixed at the refinery, E10 is 10% ethanol. I'm touring round Europe now and E5 is quite hard to find except as top priced premium fuel. Non ethanol fuel is almost non existent.

Norway you can buy 98 no ethanol from Shell, Bunker oil, its priced high on a high price! But all in all good alternative for storage bikes and old cars. World is still beeing fooled with bs about saving world from running ethanol in fuel....

Nothing to do with Norway having large oil and gas reserves? Elsewhere in the world where climate change is a genuine big issue and the finite nature of fossil fuels can't be ignored, adding ethanol is at least a carbon neutral measure to reduce the impact of motor vehicles.
