Though not required by law, riding gear is nearly as important as wearing a motorcycle helmet. This California rider isn't even wearing a shirt so he's one accident, hideous road rash, and septic shock away from winning a Darwin Award.
"My protective backpack will save me."
Remember, four wheels good, two wheels good, but mixing stupid with two wheels can be much worse than with four. And another thing, shirtless motorcycle guy, in traffic try to keep your hands on the grips. We all know you're a badass on account of your not wearing a shirt and all, but I don't want your flailing Yamaha FZ1 and limbs scratching my car when you wreck.
(Thanks for the pictures Scott!)
