The difference is the direction (type) of fold. Both can be used on either a 1-1/4” or 2” receiver hitch.
- On an HR200 Trail Rider the wheel/tire holder support arms fold up (vertically when the rack is not being used). The HR200 cannot fold horizontally.
- On an HR1000Y the whole rack folds up horizontally (against the vehicle) or down horizontally to access the luggage compartment of the vehicle.
