The Bitubo WMM twin-shock package, part number HD059WMM02V2, is a rear-suspension replacement and upgrade for 1917+ Harley-Davidson Touring Models. The setup combines spring preload, rebound, compression, length adjustment, a 306 mm length and Dark Edition finish. It replaces aging factory damping with a purpose-built Bitubo component while adding the adjustment range specified for this exact part. That gives you a more useful setup window for matching the chassis to rider weight, load, and intended use instead of being locked into a one-setting stock suspension package.

About Bitubo WMM Performance Bagger Series:
The WMM is Bitubo’s remote-reservoir twin-shock package developed specifically for Harley-Davidson Touring performance-bagger applications. With adjustable spring preload, rebound, and compression in a rebuildable nitrogen-pressurized design, it is built for heavy bikes that are being ridden hard rather than parked for show.
About Bitubo Suspension:
Founded in 1963, Bitubo develops motorcycle suspension and damping systems for street, racing, V-twin, scooter, Vespa, and off-road applications. Bitubo continues to design, engineer, develop, and manufacture its suspension products in Italy, drawing on decades of R&D and competition experience. For Elite Race Fab customers, it is the kind of hardware we like to see: purpose-built components, useful adjustment where the application calls for it, and a clear focus on getting the chassis working the way it should.
