Unless you’re planning on riding up the ramp, good luck,for a normal size,about 23 degrees.

My Harley has a ground clearance of 4.4″ , the height of my trailer is 22″ . The ramp I built is 30″ wide and 7’8″ long. This works great as I can ride it up the ramp and back it down while on the bike using the brakes to keep it under control.

I ride the bike in and slide the ramp into the brackets I built. I then hook up to the motor home and away I go. When I get where I am going I off load the Harley by putting the ramp in the slots and getting on the bike and back it down the ramp using the side rails of the ramp for support and the brakes to keep it under control.
