Recommended Pressure

The recommended pressures are starting pressures for the total weight of rider, passenger and luggage. Vary the recommended pressure to suit road conditions, riding style and comfort. Refer to Table 1.

Table 1. Rear Suspension Recommended Air Pressure

SHOCK LOAD	TOTAL WEIGHT	PRESSURE
SHOCK LOAD	TOTAL WEIGHT	psi	kPa
Solo rider	up to 68 kg (150 lb)	5-10	34-69
	68–91 kg (150–200 lb)	10-20	69-138
	91–113 kg (200–250 lb)	20-30	138-206
	113–136 kg (250–300 lb)	30-40	206-276
	136 kg (300 lb) to maximum added weight allowed*	40-50	276-345
Solo rider with capacity luggage of 36 kg (80 lb)	up to 68 kg (150 lb)	25-30	172-206
	68–91 kg (150–200 lb)	30-40	206-276
	91–113 kg (200–250 lb)	40-50	276-345
	113 kg (250 lb) to maximum added weight allowed*	50	345
Rider plus passenger	Any weight up to maximum added weight allowed*	50	345
Maximum loaded vehicle	Maximum added weight allowed*	50	345
Do not exceed 345 kPa (50 psi) rear shock pressure. *Refer to Specifications → Specifications → Weights for maximum added weight allowed on the motorcycle.

Adjustment

NOTE

See Figure 1. Use a no-loss air pump such as the DIGITAL TOURING SUSPENSION AIR PUMP (Part Number:54000033) available from a Harley-Davidson dealer. This pump can also be used as a tire air pressure gauge.

1.	Press the power button (3) to turn on the display.
2.	To switch the display between psi and kPa units, hold the power button five seconds.
3.	Remove right side cover.
4.	Remove the cap from the air valve under the right side cover.
5.	Install the pump air valve adapter (2) on the air valve. NOTE Before releasing pressure, purge the shock absorber of oil by inflating an extra 20.7–34.6 kPa (3–5 psi). For best results, press the pressure release button (1) slowly and only partially.
	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)
6.	Adjust pressure. a. Release pressure: Press the pressure release button on the pump. b. Inflate pressure: See Figure 2. Pull out the handle. Rotate the handle to the T-position. Pump until the display indicates the recommended pressure.
7.	Remove the pump from the air valve.
8.	Install cap on air valve.
9.	Install right side cover.
