I first saw the drop-down landing gear at a track day. A paraplegic sport bike rider used them on his track bike.
He was very very fast on the bike. All shifting done from the handgrip, and this was years ago.
Another young roadracer I knew lost his right arm in a crash on the track, and had all hand controls re-engineered and moved to the left grip.
He was fearless, and always rode faster than me.
OK, so y'all know... there are lots of riders, young and old, who ride faster than me.
There.
I said it.
