Oooh yeah. Believe me, I've trolled through the Touratech catalog more than once. I debated whether or not it was really necessary to add the shaft-drive protection, rear brake protection etc. In the end, most of them didn't really look like they'd add enough protection to prevent damage in a real get-off, and they're not cheap (even from "other" vendors).
I'm basing my purchase on having reviewed dozens of videos from riders who've already done the ride I am planning, and seeing the kind of terrain they have to deal with. The speeds are mostly low, so extensive armor isn't that critical, but the roads are often less than one lane wide, and have lots of protruding rocks, ungraded water crossings, and mud, and there is often a lot of sand/dust or liquid mud being flung around by other vehicles trying to navigate the unimproved sections of road. Hence, a full-coverage cage to protect against low-speed tip-overs and clipping rock outcrops, the plate to help with sliding over rocks in landslide areas, and the lens-type headlight protector to keep the $450 headlight unit from getting chewed up by flying debris and mud which would go through a mesh-type protector.
