New to GG but been riding for years. I had KYB SSS on my last few bikes (YZ250, Husky TXC310R) and they were both sent out to Factory Connection and KYB SSS are known to be some of the best out there.
Out of the box I am very impressed. Very plush (ran 18 clicks out and no preload). I purposely set them soft until they break in, but I am already getting comments from my riding partners that I am quicker especially in the whoops, which is all about suspension. It is a bit soft for me 185lbs. Had to tame down the rear with a little less rebound (2 more clicks than compression) as the rear was kicking around some, but it seems that helped significantly.
All in all I would say right now it feels even better than my valved KYB's. I am impressed with the bike and the suspension. Much better all around than either Husky or Yamaha.
