I wasn't a fan of the 2016 OEM rear shocks. They bottomed out on me quite often and left me with a sore tailbone after longer rides. I replaced them with the Fox shocks as early as possible. The difference was night and day.
My 17 Sixty has progressively wound rear shocks. When I pulled out the factory springs in the front they were also progressively wound. Interesting that when I got the fluid out there was 140ml in the left tube and 85ml in the right. The bike was brand new with 6 mi. on it. Factory screwup maybe.
