I would assume the R would take more to bottom out due to the larger amount of suspension travel. But from what I've read and watched everyone says neither model bottoms easily.
For KY riding I'd probably go for an X model. Narrower for smaller trails and still plenty of travel for rough stuff.
I agree with everything you said however my question is more along the lines of not bottoming out but the difference between r and x of just how soft it is before you bottom out. I've watched every review video possible. Sxs Blog guys seemed to like the x suspension but they did say it was firm which is why it handles so flat. They also said the r has a little more body roll which makes me wonder if the r has a softer ride overall. Maybe due to it being a true dual rate spring setup with crossover ring. I was hoping @Hondasxs mightve noticed a difference while he test drove both. Btw i hope im explaing myself well.
