With the 6.9 gallon tank on my XRR, I and can ride a 250+ mile loop without having to stop for gas. I'd like to have a good idea what the mpg is for the 520, so I can plan my rides. I know the mpg depends on speed and terrain, but if anyone can give me an average mpg, Iíd appreciate it.
I donít understand the manufacturers sell their DS bikes with those itty bitty 2 gallon tanks!
With the Clark 3.8 gallon tank on a de-smogged 2011 520 RS running 14 x 48 gearing and JD jet kit for low elevation with FMF Q pipe carrying lots of off-road tools, tubes and 2 gallons of extra fuel, a gallon of water, etc. rider weight without riding gear of 200 lbs, running Maxxis Desert ITs and ultra-heavy-duty tubes I got 140+ miles out of a tank. I was riding fairly quickly, mostly high gears, probably 60-80% WOT over mostly open, but varied terrain dirt.
I was consciously riding one gear higher when I could in order to conserve fuel. Your results may vary.
