DO NOT inflate the air suspension system until it is installed. Inflation of the air suspension system before
both ends are supported by the motorcycle’s frame and/or appropriate suspension components may result in serious
personal injury and/or damage to the air suspension system. The maximum recommended air spring inflation pressure
is 200 psi.
GENERAL INFORMATION:
Reading this manual signifies your agreement to the terms of the general release, waiver of liability, and hold harmless agreement, the full text of which is available at
Not to be stored below 5°F (-15°C) or above 122°F (50°C).Avoid damage to air lines and electrical components.Removal and installation is only to be performed by fully qualified personnel.
Damage to the motorcycle and air suspension system can be incurred if work is carried out in a manner other than
specified in the instructions or in a different sequence.
Each owner or installer is unique, therefore installation of this system can be done many different ways. The mounting locations
of the compressor and inflation switch are suggestions by our engineers. If proper wiring guidelines and instructions are
followed, relocation of the compressor or switch will neither affect the system operation nor void your warranty.
Adjust air shock pressure as required for desired ride quality to maximize the benefits of your system. Excess pressure will result
in a firmer ride, too little pressure will allow the suspension to bottom out.
To avoid the possibility of short circuits while working with electric components consult your owner's manual on how to
disconnect your battery.
Refer to the Owner’s Manual for the bike and instructions for the motorcycle lift for all correct lifting procedures. It is also
recommended that you protect any chrome or painted surfaces that may be damaged during lifting, removal or installation
process.
Use a solid, level surface to position the bike on a motorcycle lift and use all recommended safety techniques.
