Do the smaller engines get better mileage? I have a Honda 250 with a 2.4 gallon tank. Seems pretty small in comparison to what you guys are talking about.

 

the smaller the cc engine most of the time the better gas milage for sure.

 

With my 2004 Sportsman 400 the fartest I went
without filling up was 97 miles, and when I
topped it up I had 1/2 to 1 litre left in the tank.

 

The smaller engines probably get a lot better mileage. I had a Kawasaki Lakota 300cc that would go about all day on a tank that was on the small side. Same with the 250cc 2 stroke Polaris Xplorer 4x4 I had. Never went on any 60+ mile trips with them though.
