In this video I adjust the air pressure in the rear suspension on a 2008 Harley Davidson Road Glide. I use a Harley Davidson Air Pump part number 54630-03A. The rear suspension air pressure for a 2008 Road Glide should never exceed 35 psi, and the pressure is dependent on the rider, passenger and cargo weight. If the air pressure is less than the recommended amount for the load, than the bike can bottom out. This is a safety issue because it effects the handling of the motorcycle. If the pressure in the rear suspension ever exceeds 35 psi, than a failure in a rear suspension component can occur.
