GRiSO/Stelvio springs of rearshock identical?

Hi,

does anybody know if the rearshock springs of the of GRiSO and Stelvio are the same? I'd guess the Stelvio one could be stiffer due to probably higher loads on the type of bike (riding with 2 persons, luggage etc.) … hmm

thank you for input in advance,

Dietrich
