Congrats on the new machine and welcome to the Forum.
I run my Xpedition in Turf mode (1 wheel drive) any time I’m on pavement. This saves tire life and excessive wear on the drivetrain. Then 2 wheel drive on the majority of off-road riding. I only use all wheel drive as needed and only for as long as it’s needed. Such as steep rocky hills or really sandy areas. Stuff like the sand dunes is just all all wheel drive.
For the throttle switch, I typically run on normal, switching to comfort for technical parts on trails or things like loading it onto a trailer. Stuff where better throttle control is needed. Sport mode I usually only use at the sand dunes or where the tire traction is minimal. It can be a little touchy on the throttle in sport mode.
And then there’s the shock settings. 1 being the softest and 3 being the firmest, you want the lowest setting that doesn’t allow the suspension to bottom out, for the most comfortable ride.
