Yes, Eric has been banned for some time. We'll get you a close estimate for distance on that loop.
For DV you really want at least 150 mile range. Most of the routes/loops are over 100miles, many are 125-135, some are longer. There's generally quite a bit of high-speed dirt or hiway involved.
Gas carrying options are GL Mojave - drop a couple of msr liter bottles in the side bags. Add two more to a backpack. That's easy to carry and should give you about 150 miles.
I'm on a TE630, low fuel light comes on at about 110. With a 1.5gl Kolpin pax on the rack it gives me at least another 65 miles. Lately the bike has been getting close to 50mpg.
