I remember reading somewhere it was around 70-75 miles. Don't know for sure.

 

Don't know about you guys but we rode about 2-3hrs on the dunes (maybe 20min stopped) and it only was down to maybe a little less than half, while our banshee was about 1/5 left

 

it's all about your riding style... i rode over 40 miles and only used maybe 1/20th of my tank in my warrior... doing JUST trails but when i ride in snow i may get 40-60 miels max when i ride in snow cuz it's mostly WOT
