Bitubo XXZB 368mm Rear Monoshock for 2019+ BMW S1000RR - BW051XXZB1

The Bitubo XXZB Rear Monoshock, part number BW051XXZB1, is a rear-suspension replacement and upgrade for 2019+ BMW S1000RR. The setup combines pneumatic preload, dual rebound, dual compression, length adjustment and a 368 mm length. 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 XXZB Racing Series:

The XXZ is Bitubo’s top-tier racing monoshock architecture, built around low- and high-speed damping control, lightweight internal components, and a fast-response 30 mm piston/14 mm shaft layout. The XXZB version adds pneumatic spring preload with the XXZ multi-adjustable damping package, giving serious chassis tuners a very wide setup window.

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.
