"(a) No matter what's going on, you must look down before you put your foot down (duh)." - Geepers
I did much the same thing three years ago getting out of the bed of my F-250. I was in the street in front of my own garage and didn't look as I stepped off the bumper to put my left foot down on the pavement as my right hand hung on to the top of the tailgate. My truck isn't really "lifted" except by the larger tires themselves and it's a long but do-able step down. Except the asphalt had a big chunk out of it, about 12" x 12" and 3" deep and my left foot went right down into it, and folded my ankle to a 90 degree angle with a firecracker-loud crack. If I hadn't been hanging onto the tailgate, I'd have gone all the way down as I had a somewhat heavy load in my left hand. Nothing was broken, but it wasn't right for two years and still can nag at me. Had the exact same injury on the basketball court 45 years ago. Glad you weren't hurt!
Regarding the bike: my bike was delivered to me in an enclosed trailer from the dealer I bought it from five hours away from me. When it arrived, it was found on its right side, having slid across the aluminum anchoring strips for the whole trip. It had snapped its tie-down straps. $2400 in damages to replace all the right side stuff that got scratched. Suggestion: I totally "get" riding it as-is/scratched for exactly the reasons you mentioned, but it might be a smart idea, if it's only the one radiator shroud, to go ahead and look around for one (either new or used) now and set it aside. They are not going to be any easier to find or less expensive as time goes by and you might like to have the option someday of just putting that all behind you and having 'er all spit-shined again! Again, glad it didn't cost you more.
