So we know the Gunner is going to have the same small 4.5 gallon tank as the Victory Judge. So using the Judges Fuel economy ratings I figured up a crude estimate of the Gunners mileage range.
So the Judge is pegged at 42.5 mpg average. Based on a 4.5 Gallon fuel tank you're looking at a range of 191 miles to empty.
The one factor to consider here is that the Judge has a dry weight of 869 lbs vs the Gunners svelte 649 lbs, a delta of 220 lbs.
So the figure floating out there is 1 mpg gained per 50 lbs lost, keep in mind this is a vague estimation and in no way shape or form represents hard mathematical fact.
So consider: 50 into 220 4.4 times, meaning a crude estimation of the Gunners fuel economy would have to be 46.9 MPG. That would translate to a 211 mile range between fill ups...
take it for what its worth...
