The SAS Air Suspension has no compressor to mount, no hoses to run, no fittings to fail & is completely plug and play. Absolutely the easiest install and allowing you to raise and lower your rear end at the touch of a button. Add air pressure to improve ride quality, during changing road conditions or while hauling added weight. Add extra air to compensate for your passenger and then release some for solo riding. You can also release all of the air and park your bike down on the ground. Adjustable air pressure makes for a smooth comfortable ride under any condition. No more bottoming out! Comes with a black handlebar switch and a remote filtered air breather that keeps compressor clean and dry. Comes with a 5 year parts warranty and machined parts are warranted for life.
