Bitubo Race Suspension continues to apply decades of track experience to the street, this time with its high-performance XZE monoshock for the modern Harley-Davidson Softail. The XZE rear shock delivers race-proven performance in a bolt-on package for the Milwaukee-Eight Low Rider, Street Bob and other popular Softail models. Tunability is Bitubo's secret sauce, and the XZE features a remote hydraulic preload adjuster option that lets you easily set up the spring for your weight and riding style. Add in Bitubo’s unique, stepless, seven-click rebound adjustment, and the XZE can be tuned for total suspension control from a firm race feel to plush ride in a few clicks.
