I found out today how much range I have on my bike under normal desert riding conditions. I hit empty at 65 miles and was able to go 3 miles more on reserve for a total of 68 miles. I knew I was getting low, so I headed for more gas and ran out just across the street from the gas station in Ocotillo Wells. I ride with a bunch of guys with Hondas (XR650s & a CRF450) who all have much larger tanks than me. I have not heard of any great choices for a larger tank for the WR450 (I heard the IMS tank had some mounting issues with the fuel petcock?). Has Clarke or Zip-Ty come out with a good larger tank yet for the WR450? Any help on this subject would be greatly appreciated.
