I have the Touratech crash bars, great piece of kit.
Mine have been thoroughly tested, and passed. Mine was a longer slide than that in the earlier clip, then up a small bank then into some saplings, which stopped the bike going down a 20ft drop. My slide was also on the r/h side, apart from the crash bars nothing else touched down.
It took four of us to drag the bike back out, again the crash bars are useful for handholds and we could pass a security chain through them to help four old farts trying to haul 1/4 ton out of a hedge.
After all that I was able to jump back on and carry on riding.
