The Bitubo HMG1 twin-shock package, part number HD015HMG12, is a rear-suspension replacement and upgrade for 2000-2017 Harley-Davidson SOFTAIL. The setup combines spring preload, compression, length adjustment. 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 HMG1 Softail Series:
The HMG1 is Bitubo’s twin-shock solution for Harley-Davidson Softail models, with continuous preload, compression, and length adjustment in a nitrogen-pressurized package. It is built for riders who want to tune both ride quality and rear ride height while keeping a clean custom-bike presentation.
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.
