AIR SUSPENSION PUMP AND GAUGE	HD-34633	1

General

See Figure 1. All models feature air-adjustable rear suspension. Air pressure may be varied to suit personal comfort.

For FLHRS models, refer to Table 1.
For all other touring models, refer to Table 2.

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.
ON FLHRS MODELS: Always clear the line by adding 3-5 psi (21-35 kPa) before releasing air from the pump's valve, but do not exceed 50 psi (345 kPa).
ON ALL BUT FLHRS MODELS: 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.
