Replacing the fork springs is the first step in customising the front suspension to suit the rider's needs, whether for intensive use on the track or on the road.

LINEAR SPRINGS
Linear K-rate springs are ideal for sports bikes that require a uniform response over the full travel of the front axle.
They are available in different levels of rigidity, for different focusing needs.

PROGRESSIVE RESULTS
Progressive K-rate springs are ideal for Touring and Naked motorbikes, which have a wide range of uses. They offer driving comfort, stability and safety, even under heavy loads.

TECHNICAL CHARACTERISTICS
Bitubo fork springs are made from CrSi alloy steel, heat-treated, shot-peened and finally compressed. They guarantee very high performance over time. Unless otherwise stated, a specific oil for the various applications of the model is included in the kit. The choice of viscosity is the result of the experience acquired by our Bitubo development team.

The assembly instructions contain details of the type of oil and the quantity required.
