TLDR; slow rider, wants to do some longer trips around Europe on a mash two fifty. Yay/nay?

Full text: I was looking at doing some road trips around Europe, and truth be told, I'm not one for ludicrous speed. I like slower rides, with a great view, and will gladly take an extra hour or two to have that view of an awesome valley. I rode a Honda cbf 125cc up until 2022, but it was just a bit underpowered as it struggled to do 90km/h or 55mph uphill and I never did long trips, longest I did was around 2h. So I was looking at a mash two fifty. It seems to top out at around 115km/h or about 70mph which seems great for me. I've read some good reviews about the bike, but I'm not sure if taking longer trips is okay. Mind you, I would take a break every 1.5-2h and would probably not ride more than 6h a day. A 250cc would be really perfect for me, both for fun and budget (insurance and road tax would be dirt cheap), but it seems those options are limited nowadays.
