Get the leather ones with tassels. Wear spurs and a large-brimmed hat that can trail behind you when you go fast.
Refer to your bike as a steed, chew tobacco and carry a revolver. Cars won't mess with you. No-one will.
BONUS TIP: Ride a tall bike, and measure its height in "hands". Refer to the guys you ride with as a posse. Start a brawl in a saloon. Fill your panniers with beef jerky. Yee-hah!
