Strict speed limits in Scandinavia, so the X-Country will be fine
FWIW. And slightly OT.
Going up there in 3 days, regardless of the selected route, is not much of vacation pace. If you go through Sweden it is stil 700 km a day. A 3 day ride means keeping 120km/h on the clock for 8 hrs. driving a day. That's quite a pace for a 650.
If you go domestic, it means 800km a day, and you may expect to progress 60 km/h, i.e 13 hrs of riding + stops.
May I humbly suggest that you spend at least one more day going up there….
