jumping is is definitly fun wheelies are just addicting there just as fun but in a different way. But why would you want to case a 50 foot double, clear that thing

Hey i was wondering if the guys in those video have some sort of after market grab bar on the rear of there bikes that hold up better when there draging it on the ground. Also is it real bad for the bike if when your doing wheelies you don't use the clutch to shift?
