I always ride in and slide out in neutral! I'll use the front brake while backing out, if it slides a little no big deal then when I feel the back wheel go off of the ramp I loosen up on the front brake and with both feet on the ramp sliding backwards it rolls out. Just make sure you keep it straight upright and don't panic and tighten up on the front brake because when bike is 1/2 way off of the ramp your feet may not be touching! My toy hauler is pretty easy...it is a little squeamish backing it out of my 1 ton dually on my triple 9ft ramps!!
