Derived from the multi-award-winning XXF, the Mono XXZ, until now reserved exclusively for our official teams, is now at the cutting edge of technology, with a completely new design and a host of new technical features, including 4 settings: compression and extension at low and high speeds, with new configurations designed to give the rider the best possible feeling.  Inside, it has been updated with technical solutions that optimise the fluidity of moving parts, improve the damping coefficient and increase stability at high temperatures, not forgetting the use of lightweight materials to reduce overall weight.  The Ø14mm stem increases fluidity and the Ø30mm piston reduces the mass of fluid in motion for a faster response to stresses. Particular attention has been paid to increasing the sensitivity and precision of settings.  XXZ is designed to reduce inertia and provide immediate control of suspension oscillations.
The aim is to provide the rider with greater driving precision and grip than ever before, as well as uniform tyre wear thanks to instant control of the forces at play. This gives the rider maximum support in bends, even at extreme lean angles, rapid changes of direction, maximum confidence in opening the throttle on all types of track, and perfect rear-end stability even under the most violent acceleration.

BITUBO XXZB1 Rear Shock Absorber (ref. BW047XXZB1) — Designed for roadsters and demanding riders, this mono derives from the XXF range and features an architecture focused on precision and sensitivity. Its design has been revised and the interior optimized to limit moving masses while improving fluidity and thermal stability.

• Ø30 mm Piston and Ø14 mm Shaft for quick response and better sensitivity to small oscillations.
• DLC treatment on the shaft to reduce sticking and increase consistency in performance.
• Adjustable double compression (low and high speed) and rebound to adapt the settings to winding roads as well as sharp accelerations.
• Pneumatic preload available (rechargeable reservoir with quick connection sold separately) for fine adjustment of the preload.
• Lightweight materials and settings designed to reduce inertia and improve rear end control.

Settings: low speed compression 24 clicks, high speed compression 20 clicks, rebound 24 clicks (including high speed rebound 20 clicks), pneumatic preload 10 mm = 10 clicks. Included: specific model instructions and adjustment sheet.

Ideal for those looking to refine the behavior of the rear end, regain stability out of corners, and achieve precise feedback at the handlebars. Check compatibility with your machine (e.g., BMW HP4 ABS 2013‑2014) before installation.
