I agree on that. Just over 4gal on the 500efi is probably good for about 100km the way I ride. I've done 80km on a little over 10litres, so that's 8km/l and mapping that forward would yeild about 120km (75miles) per tank.

My warrior on medium trail riding would hit 150 - 160km on it's 9litre tank, easy.

 

Arctic Cat has the right train of thought,there smaller 400 has a massive 6.5 Gallon!!tank. They must bring there snowmobiling expertise over to there ATVs yet Polaris does not.

 

I've had my 06 500 efi for 1 yr. tomorrow, have 3300 miles on it and not a singlr problem other than false "HOT" signal which was fixed by dealer immediately. I would go with efi as fuel economy is better and cold weather starts are easy.

 

Not from what we noticed. We fill up both bike head out for a long ride and when we top off to replace what we used during the ride the difference is less than a quart of fuel. Defiantly not enough to nearly make up for the 4.26 L smaller tank he has.
