Actually reminds me of a time a guy and I were riding (both experienced) and met a newb on the hill (outside of Palm Desert on hwy 74). Hadn't had his bike long, bought a new R1 of all things. We weren't out to race around or anything, not even trying to go fast, but we told him don't try to keep up anyway. Well I was on my "little" 600, guy riding with me had an R1, and newb decides to try and keep up anyway.
Like I said, we weren't even going fast, but I kept watching my mirror for the kid behind us. Crusing along headed down the hill to the city, come into a sharpish 180. Come out of it and onto the straight and still watching my mirrors, only the kid isn't back there anymore. We slow down, still not there. Stop and wait a moment, still not there. I turned around and headed back to find him and his new R1 laying in the middle of the road. He came into this turn, got scared, stood on the rear brake and locked it up, and went straight into the rocky hillside.
Shattered his arm, broken scapula, ruptured liver, bruised kidneys. Was talking to him later in the hospital and he said he saw that little 600 in front of him and figured he could keep up. Accident prone kid, had previously broken his back in a jet skiing accident.
