Burned 4 gallons of 100 octane during my 4 hour practice session today...
The 500 will get 38mpg cruising over long distances, but the fuel economy goes south really quick when you are cranking the throttle WFO around actrack.
Big Bell Mine at Chloride City, California - about 5 miles from the Nevada border. It's a full day's ride to get there. I slept really comfortable on those old bed springs...
