AirCells were scientifically designed to control the compressed air pressures and flow rates in your forks. AirCells will improve the feel of stock, modified or the high dollar "works forks" - Guaranteed!

AirCells reduce the harsh feeling over braking and acceleration bumps, whoops, tree roots, rocks and over-jumping. Also, the cornering is improved dramatically! Head-shake is reduced or eliminated, arm pump and fatigue are reduced as well. The AirCell Fork Air Control System will equalize the air pressures of both forks, creating a totally balanced front-end feel! They are absolutely the best Fork Tanks you can buy!  Period!!

Almost none! You will never have to worry about the oil accumulating in the AirCells. Built inside each AirCell is an "Automatic Oil Return System" (referred to as AORS). With every rebound stroke of the fork, any oil that has migrated into the AirCells is automatically returned to the appropriate fork.

Absolutely! Each AirCell has an adjustable Air Compression Damping Valve (ACD Valve). This valve controls how fast the compressed air can enter the AirCells, allowing you to control how plush you want your forks to feel and how much dive your forks have entering a corner. The ACD valve has an internal by-pass system that allows the high pressure compressed air to return to your forks un-restricted. This helps eliminates suspension packing. You have complete control!

Here are a few guidelines for deciding. We strongly recommend you always check your motorcycles owners manual for recommended compression and rebound settings before adjusting the oil level.

Assuming your springs are right for your weight and riding ability - NO. If you are not bottoming out on the largest obstacles (jumps), you should not have to add any oil. Light bottoming a few times per lap is acceptable. If you are bottoming hard, you can add 5 cc of oil to each fork and then re-test until the bottoming is minimized.
