My 300 is a '13. So it has a button, it just doesnt work
I have not even touched a clicker or set the sag on the 150, and the suspension from the factory is 100x better than the revalved and resprung, dialed in stuff on my 300. Its not even close
I personally like the open cartridge WP Xplor stuff. It's great for moderate speed technical trail riding (what I do). I set the sag on my 150 and put the clickers between the factory "comfort" and "standard" settings. That's it. Luckily I fall right into the weight range of the stock springs at 170lb with gear.
Hard to turn away a 20+ Sherco or Beta since they have both gone KYB now on the factory/race models
But I also agree that the new KYB stuff is nice. Better at faster speed chop thanks to the closed cartridge, but not as plush as open cartridge.
