4.2 gallon (16L) add-on tank increases fuel capacity from 2.4 gallons to 6.6 gallons. This tank drapes over the motorcycle in the location of a normal fuel tank ahead of the seat. It drains by gravity into the original underseat tank. Installation involves attaching special fuel fittings thus drilling holes into the bottom of the BMW underseat tank.
With the excellent fuel mileage of the G650X (60+mpg!) it becomes a capable long-distance traveler.
USA D.O.T. certification is not available for this tank and thus we consider it for "off-road use only".
These tanks may be on backorder, the best way to get one is to confirm a backorder, they are flowing thru but the best way to get one is to get your name on the list.
