i think it's dependent on the bike the forks are on and the weight of the rider... to my knowledge the sbk forks come with a .95 spring because of the heavier bike weight and forward weight bias. when i say heavier, it's in reference to a monster or supersport. the monster and supersport spring rate is .9 and is a bit anemic for larger riders. i've found that the sbk forks grafted on to my 900ss are more than adequate for my 225lb lard ass. whereas they are sorta soft on a friends 996.....I've heard some say the sbk's are on the soft side and others say not..
Re: oil After doing a little research on fork oils I am going to go the expensive route with the Ohlins oil...the bits of info I have gleaned which of course could be marketing bull....is that the benefits of the more expensive oils are prolly worth it....What fork oil are you folks using?
