BITUBO XXZ Rear Mono Shock
Ducati V4 (2025)

Since 1975, Bitubo has been the ideal solution for those looking for the best from their machine: performance, comfort, driving precision, and above all, the quality of an excellent product, continuously developed in constant collaboration with advanced research centers, tested and developed with fatigue and destructive tests, both in software and dynamic simulations.  Bitubo products are used in WSBK, BSB, CIV, CEV, IDM, and many other national championships around the world.

XXZB1 Racing Rear Shock 

Derived from the multi-victorious XXF, the Mono XXZ, until now reserved only for our Official Teams, confirms itself as technologically at the top, presenting itself with a totally renewed design bringing with it many technical innovations, such as the 4 adjustments: compression and extension at low and high speeds, with new settings designed to give the rider the best possible feeling.
Inside it is renewed with technical solutions that optimize the smoothness of the moving parts, improve the damping coefficient and increase stability at high temperatures, without forgetting the use of lightweight materials to lower the overall weight. The Ø14mm stem increases smoothness while the Ø30mm piston reduces the masses of fluid in motion for a faster response to stress, particular attention has been paid to maximizing the sensitivity and precision of the adjustments. XXZ is designed to reduce inertia and ensure immediate control of the suspension oscillations.

OBJECTIVE is to provide the rider with a precision of driving and an increase in grip never seen before and a uniform wear of the tire thanks to the instant control of the forces in play. This gives the driver maximum support in curves even at extreme angles of inclination, fast changes of direction, maximum confidence in opening the throttle on all types of track, perfect stability of the rear end even in the most violent braking.

TECHNICAL FEATURES:

DEDICATED TO THE MOST DEMANDING is the most extreme version of our XXZ, the stem is treated for stable performance over time.
DLC STEM TREATMENT for reduced friction, and therefore greater sensitivity during suspension oscillations. PNEUMATIC PRELOAD, previously available only for Official Teams, is now available!
