Congratulations on your purchase of an Arnott® Motorcycle Air Suspension system. This system provides you with the ability to maintain your bike at a constant level regardless of load, resulting in enhanced vehicle ride, handling, and performance. We at Arnott Incorporated are proud to offer a high quality product at the industry’s most competitive pricing. Thank you for your confidence in us and our product.

Proper installation is essential to experience and appreciate the benefits of this system. Please take a moment to review these installation instructions before you begin to install these components on your motorcycle. The removal and installation of air suspension products should only be performed by a fully qualified, ASE Certified, professional.

It is equally important to be aware of all necessary safety measures while installing your new Air Suspension System. This includes proper lifting and immobilizing of the motorcycle and isolation of any stored energy to prevent personal injury or property damage.

1. Screw a VOSS fitting into one of the air shocks. Pull out the white plug and insert the 4mm air hose until you feel it seat. Unscrew the VOSS fitting from the shock and verify that the keeper is attached to the hose. Screw the fitting back into the shock and snug tight with a 10mm wrench. (FIGURES 1, 2 ,3)

2. The orientation of the VOSS fill port can be changed in relation to the shock mounting eyelets. Unscrew and remove the shock can. Snug the lower shock eye in a vise. Grasping the lower portion of the air spring and twist it on the shock body until the desired clocking is reached. Flip the shock in the vise. This time gripping the other end of the air spring. Twist to realign the shock eyes. (FIGURES 4, 5, 6, 7)

4. On rebound adjustable shocks, the rebound damping force can be increased or decreased to suit the rider’s preference. Increasing the rebound damping will slow the speed at which the shock extends after it is compressed. This is usually desirable when running higher air pressures than normal for a single rider. For example, riding 1 up would require lower air pressure and less rebound damping than riding 2 up with a fully loaded motorcycle. The increased air pressure is trying to extend the shock faster. This can lead to an uncontrolled bouncy feeling in the rear of the motorcycle. Increasing the rebound damping will help slow down the extension and make a more controlled feeling. (FIGURES 10, 11)
