I'm contiplating adding a hack to my adv moto. Any ideas what would be a good hack for a bike like this? Probably be used for grinding up the gravel roads, not real off road stuff. I have a Champion Escort on my old cb900 but that chair is more of a highway outfit. Been thinking velorex or Sputnik. Any thoughts? Oh yeah, it's a 650 parallel Twin Kawasaki Ninja motor.
