I had a cbr600f2 back when the f2s were cool. I traded it for 3 broken metacarpels(the slowest bone in the body to heal I found out), a broken collar bone, and 40 stitches in the back of my head and 3 pins and a screw! When I start dreaming of getting another I just scratch the scar on the back of my head, I scratch my head alot.......
