This motorcycle bag is a really good value for the money and has been designed with a clever magnetic feature. That means that the bag fixes onto your motorcycle fuel tank using extra strong magnets. The bag is best used for motorcyclists who do not ride too fast as it does not contain any straps. However, what this magnetic motorcycle tank bag does contain is a non-slip bottom that is scratch resistant and keeps it firmly in place without causing any damage to your tank. The magnetic tank bag has been manufactured from 1680D polyester and has an expandable cargo with a zipper and clear map pocket so you are able to look at your map without having to remove it from the compartment.
