Legend Aero Air Shocks allow the rider to experience all the benefits of a traditional air suspension, with the added kicker of a model-specific, bolt-in on-board compressor. What does this mean for a rider? The ability to adjust ride height on-the-fly by way of the included handlebar-mounted compressor switch. Adjustable air suspension has never been so accessible - custom suspension at bolt-in prices, with bolt-in installation. Legends packed a lot of value into this kit!
