1

General
See Figure 1. All models feature air-adjustable rear suspension. Air pressure may be varied to suit personal comfort. Refer to Table 1.
NOTE
An AIR SUSPENSION PUMP AND GAUGE (Part Number:HD-34633) is available at your Harley-Davidson dealer.
Figure 1. Rear Air Suspension Air Valve
Rear Air Suspension
See Figure 1. Adjust the rear shock air suspension pressure by adding or removing air from the air valve located just below the frame cover on the left side of the vehicle.
NOTICE
Do not exceed maximum air pressure for suspension. Air components fill rapidly. Therefore, use low air line pressure. Failure to do so can result in possible damage to components. (00165b)
NOTE
Using pressures outside the recommended loading range will result in a reduction of available suspension travel and reduced rider comfort.
WARNING
Use caution when bleeding air from the suspension. Moisture combined with lubricant may leak onto the rear wheel, tire and/or brake components and adversely affect traction, which could result in death or serious injury. (00084a)
NOTE
  • Do not exceed max GVWR.
  • Always clear the line by adding 3-5 psi (21-35 kPa) before releasing air from the pump's valve, but do not exceed 35 psi (241 kPa).
  • These are recommended starting points. Adjust to suit load conditions, riding style and comfort desired. Less initial pressure does not necessarily result in a softer ride.
