This purchase is for a passenger grab bar/luggage rack with side cases for the above bike model. The removable cases can support up to 6 lbs on each side. The luggage rack has mounting points in the center rack to allow the use of aftermarket luggage and also provides mounting points for straps and bungee cords. Made of steel tubing, the rack has six mounting points to prevent them from rotating in the event of a low side. We use highest grade bolt commercially available 12.9(177,000 psi in tensile strength) wherever possible. Rest assured that you are getting the best material commercially available.
