Looking for some educated input on something I don't know a tremendous amount about. I checked my suspension settings, as delivered from the dealer, on Sunday night. They were all, bar one, in line with what is listed in the owner's manual.

I weigh 167, so the bike is set-up for the 170-190 range, now with a couple of variances that I tweaked(Rear preload = Notch 5, Rear compression = 16 clicks out) more in line with 190-210 weight.

The only adjustment that didn't look right (again, per the manual) was the Rear Rebound. By the book, that looks like it should be 1 turn out from Max. But my bike as delivered was 1 1/2 out. Does the dealer know something I didn't?

I wouldn't assume that they even looked at the settings.

What you really want in damping is for both ends to work the same. With the suspension warm, bounce the bike by pressing down on the tank/seat and letting it rebound - do both ends work the same or is one faster than the other? Same thing with hitting bumps quickly enough that they seem like one impact for both wheels - is the recovery the same, or does one end seem to stay compressed?

Generally the sequence is to set the preload/sag, then set the rebound damping to control that rate and the rider weight - then fiddle with compression on a preference/surface basis.

Kevin, thanks for that. I wasn't willing to work on "they probably did it" assumptions either, but was pleased to see my dealer set the bike up in the range I asked for. The only one outside of the specs (or even the manual) was the rear rebound, which led me to think there could be a reason. I'm probably not a good enough rider to even notice fine differences, but this is how we learn!

Try making some *big* changes - move that rebound full soft and full hard, play with the bike and see the effect. It's really hard to tell minor changes, much easier to go from way off to very close. The changes are easy to make and to recover from; you won't hurt anything by playing.
