MPG with stock tires on 450?

You shouldn't have a problem with that distance. On mine I'm running 27's and I get around 30 miles on a tank. You shouldn't have a problem with stock tires.

My Foreman 500 gets 42 mpg.It's completely stock with 25" dirt devil tires.I don't run it hard.I can get over 100 miles on a tank driving on trails and county roads going 25-30 mph.The mileage really drops when I hammer on it and play in the mud,hills,etc.

Thanks guys, I hope to put some miles on the beast soon. So much stuff to do, so little time. i might just have to go solo this weekend.

I have 27" bearclaws supertrapp pipe K&N filter and jet kit and i get 50 miles or more per tank

I have 26 inch Mudlites and I get a little over 60 miles before reserve.

Foreman gas mileage

I went to Windrock a couple of months ago - managed about 52 miles on a tank before going to reserve. I stayed in 4 wheel drive most of the day riding the difficult trails - Riding in 4 wheel drive cuts mine big time!

I've checked mine several times running 26" tires. 25 MPG everytime. I have run 72 miles on 1 tank before and thought i was on fumes. But when I filled it up it took 2.95 gallons. I was at 60 miles also when I had to put it on reserve.
