    Thanks. The 7.5 seems to be the good choice.

    You will want to use maxima "heavy" weight shock oil. They sell a light, medium and heavy weight. Or a 10wt shock oil of your choice. In my opinion anything lighter just makes the rebound to fast.

    I have used both at different times. I prefer the Ohlins oil but I also like the Maxima heavy weight. I believe the Ohlins oil is a 10wt. but I am not 100% sure on that as they have reformulated it over the years.

    This will not answer the original question, but is important to note that Ohlins Shock Absorber Fluid comes in three different weights:

    28.0
    18.0
    14.0

    all measured at cSt / 40 degrees C

    Attached is a catalog page from Ohlins and a viscosity chart to convert cSt / 40C to SAE weights.

    Thanks Vinskaord, but cSt/ 40 degrees C looks like Chinese to me.
    I'm taking differents informations . Seems that 7.5 w to 10 w must be the good oil.

    The viscosity chart shows the approximate SAE equivalents. Although it is preferred to use the oils cSt/40C weight - here is a 'wag' (wild a** guess) for SAE weights:

    28.0 cSt/40C = 15W
    18.0 cSt/40C = 10W
    14.0 cSt/40C = 5W

    Check the cSt for whichever oil you end up choosing for an exact match.

    That's more comprehensive. 10 w is good for me !
