Yeah, I got my knee down today.
and my ass, elbows, back and chest :/
My first sliding down the road experience wasn't all that pleasant tbh. Just glad it was low speed (< 30) and that I was actually wearing my armoured jacket, jeans and gloves.
For those who want to know:
I went through a patch of diesel/oil whilst braking, the front wheel locked and slid. Before I knew it I was on my ass. Fortunately I've only bruised a finger and thumb, my bike on the other hand is going to need a litte TLC on the scratched chrome
