Racetech is probably the only source that tells OEM springs to be 4,4, either we have different setup in Europe and USA or RT are wrong.

What about the shock? Is the springrate ok, or does it have to be stiffened too when upgrading the fork?

Well it looks like they upgraded their website and offer another spring.
Now .75kg and 95kg. Still seem heavy to me. Especially when compared for other springs offered for this bike. Ohlins .55kg, Bitubo, Standard Hyperpro progressive .52-74kg.

A caparable bike that is heavier, especially in the front. Stock 950 is 4.5NM which converts to .49kg. Koonz racing offers a .62kg spring for the 800xc which is also heavier than a F800 in front.
