[QUOTE="Fred W, post: 1314881, member: 3828"] Except it doesn't actually work that way. You can't make a spring increase it's spring rate with preload. When you crank up the preload (by any means, either screwing down the adjusters or adding spacers inside) all you are going to do is alter the ride height. The spring will still compress the exact same amount inside after you put a static load on it, and it will still deflect at the same rate from there because the spring rate is the same Where did you get that info? The ES has the totally different, upside down forks. The FSM does says the 2013-2015 A model has a dual rate spring, 0.85 kg/mm & 1.02 kg/mm, but the ES model claims to have a single rate spring for all 135mm of travel. They say it is 2.04 kg/mm, but I assume that to mean the sum of the two fork springs. In any case it is a single, stiff spring rate on the ES. Why they changed how they are specifying the spring rate for the ES is anybody's guess. [/QUOTE]
