The tank has a real tight fit which might be a bit stubborn for trail maintenance. I'm real happy I can get a tank in this size. I run 4.5 gallons on my WR and that seems to be enough for any trip I've done without being cumbersome. I'm guessing the DR will get better mileage than the WR and 4.2 gallons will take me just as far on this bike.
I prefer the clear tank so I can see how much gas I have, but I know it's not the best looking thing out there.
