About Bitubo MFORK Series:

The MFORK line is Bitubo’s fork-spring upgrade program, with application-specific linear or progressive spring rates and dedicated fork oil where specified. It is the logical first suspension move when the stock fork needs better support or a spring rate better matched to the motorcycle and its use.

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.
