Now that I know I'm not the only one who thought the pro bikes look low in the rear, it's got me obsessed a little. Let's first accept that pro suspension is nothing like ours. The similarity ends at how it looks and the purpose they serve. With all the changes the teams make with geometry,it would be no surprise that they are able to alter the sag
height. My best guess is that they run a stiff spring with less preload and then alter the valving and other internals to run deeper in the stroke. I'm sure they can stand to loose an inch+ of travel to optimize geometry for corners and such. Really if you think about it the pros intend to land jumps perfectly every time so less travel can work. I recall a post on here a while back where an A rider and his suspension guy had found 118-120 mm of race sag to produce the best ride on a 2014 yz450f. If that's where the geometry come together to produce the best handling why not alter the shock to run in that part of the stroke?
