Is buying a motorcycle in Germany and importing it to Finland worth it?

I’m new to Finland and have noticed that used motorcycles often seem cheaper in Germany. Has anyone bought a bike there and brought it to Finland? Is it possible to buy it in Germany and ride it back to Finland, and what would I need for that—temporary registration, insurance, or export plates?

What was the full process for tax, inspection and Finnish registration? After transport and paperwork, did it still work out cheaper than buying the same bike in Finland? Any common mistakes to avoid?
