For those of you who wear jeans, talk to PacificBusa! Have him send you a photo of his ass after he crashed at 70 mph wearing jeans! It's an ugly site of raw flesh!
I crashed a busa two years ago at 70 mph. Hauled the busa home in pieces but I was unscathed, thanks to full gear. I was beat up and bruised but no serious damage. You'll never catch me in jeans nor a T-shirt on any kind of scooter!
One other thing, boots are extremely important! Ones that buckle up tight above the ankle so you don't loose them during a crash. If you watch the stunter kids crash wearing tennis shoes, they always loose their shoes as soon as they hit the ground leaving their bare feet out there to take a beating and grind the ankle bone down a few cenimeters!
