Original design of this motorcycle included some fuel storage in the hydro bent frame itself. This was dropped in final design but would make a great reserve tank. The fuel capacity is large (5.0 gallons) however consumption rather high and the fuel gauge is very inaccurate so high liklihood you will run out of fuel on the road if you donĀ“t refill at or before 1/4 tank remaining. I have run out of fuel twice! One time on the Interstate where there were barriers on the edge of the road keeping me boxed in -- very dangerous situation to be in.
