BMW F800 GS Auxillary Tank

Never before has an efficient design like this been available for long distance riders.  Are you one of those people who like to take the path less traveled?  It's less traveled because there are no gas stations where you are going.  This tank can boost your range to over 300 miles of hard riding.

The all-new F800GS AdvTank carries 1.6 gallons of fuel, and includes the beefy Aluminum Anodized Top Rack. 

The fuel delivery system fits right into your existing vent line on your BMW.  Fuel is fed from the AdvTank into your stock tank via the vent line.  The AdvTank drains first, and then becomes a component in your vent line. 

The AdvTank is contructed of heavy duty plastic and has been tested extensively.

There is no need to remove your Carbon Canister. 

The kit includes the AdvTank, the Top Plate, and all necessary mounting hardware including posts, bolts, fuel line, vent line, and gas cap.
