If you are going to use it for more work than play get the Foreman. The larger size will come in handy with heavier work, yet will not be an issue when playing on the trails.
Good point, the guys at the dealership steered me away from the Rancher FI. They said they had much more problems with those and to wait a year or 2 untill the ATV FI got sorted out better. One guy said they were having to install new spark plugs left and right on the Rancher FI to keep them running right during display BEFORE they were sold.the rancher is also EFI, i perfer a carb bike- foreman. IMO
