Legend Suspensions AXEO21KO Front Suspension Kits include two identically built cartridges with our unique design due to a floating piston that separates the oil-filled damper from the nitrogen chamber and touring spring rate. This kit will only fit the 2018-2022 CVO Road Glide with the OEM Knockout 21" front wheel. The AXEO21KO kit we offer has a longer cartridge length than the travel limiting kit we offer and does not require the travel limit collars to be used in the lower fork leg.
