General description

XXZ 31 B1, the extreme evolution derived from the multi-award-winning XXF and previously reserved only for our official teams, confirms its position as a technological leader and presents a completely renewed design that brings many technical innovations, such as the four adjustment possibilities: compression and extension at low and high speeds, with new settings that provide the rider with the best possible feel.
Internally, it has been updated with technical solutions that optimise the smoothness of moving parts, improve the damping coefficient and increase stability at high temperatures, without forgetting the use of lightweight materials to reduce overall weight. The Ø 14 mm rod increases smoothness, while the Ø 30 mm piston reduces the mass of moving fluids for a quicker response to loads. Special attention has been paid to maximising the sensitivity and accuracy of the settings. XXZ has been developed to reduce inertia and ensure immediate control of suspension vibrations.

The aim is to give the rider precise control and increase maximum grip, as well as consistent tire wear, provided by the immediate damping force. This gives the rider confidence in corners, even at extreme lean angles, during quick changes of direction, and under hard acceleration. At the same time, it ensures excellent rear stability, even during extreme braken, regardless of track or surface conditions.

Dedicated to the most demanding riders, it is the most extreme version of our XXZ; the piston rod is treated to achieve stable power, performance over time.

The pneumatic spring preloader, previously only available for official teams, is now available to everyone! Precision, speed, and lightness are the essence of this new adjustment device. It operates via a rechargeable fuel tank with a quick connection, available when needed.

DLC coating of the piston rod to reduce friction and thus provide immediate damping feedback for suspension vibrations.
