A stone shield would help for the small stuff for sure. I've considered it myself, as the 'dangle angle' of the S1 is a bit more exposed with a bigger filter.
The filter I run is both larger in diameter and longer than a stock filter.

Forgive me for the angles, I needed another person to shoot these pics:
Bottom line is that it IS exposed. There is a chance you could take this sucker out with a road hazard or a deep pothole.
I'll probably fashion some sort of skid plate for this one when it goes in. But in the long run, the Zilla isn't a daily driver except in the late spring-early fall timeframe. Not much inclement weather or bad conditions.
For most 87-99'* here? Probably not a great idea.
