The Bitubo CYU1 Rear Monoshock, part number BW048CYU11, is a rear-suspension replacement and upgrade for 2013-2017 BMW F. The setup combines spring preload, rebound, dual 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 CYU1 Dual Sport Series:
The CYU1 is Bitubo’s fully adjustable long-travel dual-sport rear monoshock with manual spring preload, separate reservoir, low/high-speed compression, rebound, and length adjustment. It gives adventure and dual-sport builds a much wider setup window than a basic replacement shock.
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.
