300 kilometres is a standard driving day on backroads, accounting for lunch and breaks. 500 kilometres is a sustainable maximum for highway driving. I only do the latter when I really have to. On long trips I estimate 200 kilometres a day, or 2 days on, 1 day off.

With a comfortable motorcycle this is perfectly reasonable. I have a 2017 V-Strom 650 and it's perfectly suitable for the task.
