As for sports type bikers they dont go out unless its a sunny day with no chance of a spot of rain...
Bwahaha! Actually, I have. Used to go to rallies with a mate called "Animal". Crazy ****er he was. He once jumped off his scooter at about 40 mph to bite and generally **** up a greasy biker who'd been foolish enough to try and kick him as he rode past. He sorta warned me he was about to do it. I managed to grab the handlebars and come to a stop, but I still fell off. Keep the faith. Happy days.
