Does anyone know the approximate range for a 660?

I fully realize it depends directly on how and where you drive the machine. I'm just trying to get a ball-park average.

 

I have a trail tech speedo.. so my numbers are pretty solid..

I can do 60 miles semi beating on it.. 80 if I'm light on the gas and riding for distance/fuel not performance.. these numbers are for wood trails riding

about 40 in the sand..

These numbers are full tanks, run to empty (literally)...

 

It may depend on whether you are talking about the Grizzly or the Raptor. I just put 67 miles on my Grizz (first tank of gas)and used 3/4 or a tank according to the gas guage. Take into consideration I'm only breaking it in so I haven't been hard on the gas yet. Hope that helps.
