The luggage racks came with the ability to attach a 1 gallon Rotax fuel container. Not needed under normal circumstances as the tank holds 6 gallons. However, the GSA WAS 7.5 gallons, and this puts the R back on par with the range. It also officially fills the space that was unofficially filled with the fuel bottle container. The Molle-attached pouch on the Mosko bag can now be used for something else.
