Where in Norway are you? A few months ago I traveled to Oslo, Gran, Molde, Stavanger, and Svalbard it was an amazing trip!

You should try and ride this road on your motorcycle [its outside of Lysebotn, close to Stavanger]

Anyhow, octane ratings in Europe are different than octane ratings here in the US and Canada. 95 octane in Europe is very close to 90 (89 octane is mid-grade usually) here stateside. 98 octane in Europe is roughly equal to 93 octane, or premium here in North America.

So i should use the 98 then? But shuld i use lead replacements?
I live in bergen. Just north of stavanger. I will try to drive on that road this summer

Yes, I would run the 98. From the specs I looked it, it seems as though that little 440 has a compression ratio of over 9:1 so the higher octane fuel would be good.
