Dirt bike gas mileage?

Question

how many miles per tank of gas does a 2005 yamaha ttr 125 get in pretty rough terrain?

Answer 1

This is nearly impossible to figure given the parameters. What your really looking for is hours per gallon not miles per gallon. My Jeep gets 22 mpg on the highway if I'm care-full but only around 12 mpg running fast fire roads and when I'm in the rocks I've got as low as 4 miles for 10 gallons of gas.  Of course it took almost 8 hours to traverse those 4 miles. Your 125 should get around 65 mpg on the road but in rough terrain I wouldn't look for more then 20mpg.

Answer 2

there are so many variables to consider, carb, pipe, tank size, your speed, on road, off road. gear. etc.

on my YZ 125 i can go most of the day on one tank, but

it could range anywhere from 30-60 miles.

i get about 45 with my yz and that has a FmF pipe front to back.
