The K-FORK valve kit upgrades the hydraulic control inside the original road fork with rebound and compression pistons, shim stacks, and application-specific setup information. It is built for riders who want more disciplined fork behavior while keeping the factory fork bodies.
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.
