Hello WR owners, On the 25th I leave for Big Bend with These guys. I have an Acerbis 3.3 gal tank mounted on a 2006 WR450F. I'm wondering what the average expected mileage would be with one of these tanks mounted? We will be based at a hotel and may have to ride 30 miles or so before even hitting the jeep trails. Any more than that and we will trailer to the trail head. My travel partner is riding an older XR400 with 4.0gal tank and our plan is to arrange rides with others that will be attending. They could be on big GS's, V-Stroms, KLR's and others but most likely we will group with other XR's, DRZ's and WR's. This is my first Duel Sport ride and I have no idea what the WR's range could be with 3.3gal much less the stock tank. Hoping to hear of your experiences and suggestions.
