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 technical innovations, 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 piston blade 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 adjustments. 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 when cornering, even at extreme angles of inclination or during rapid changes of direction, maximum confidence in opening the throttle on all types of track, and perfect stability of the rear end even during the most violent accelerations.

BITUBO XXZ81V2 Rear Shock Absorber — manufacturer reference A0050XXZ81V2. Developed from BITUBO's innovations and derived from competition models, the XXZ81V2 offers a rear suspension designed for demanding roadsters. Its design incorporates internal solutions aimed at improving the fluidity of moving parts and thermal management, while limiting oscillating masses for a more responsive suspension.

• Type: mono shock, suitable for roadsters
• Piston diameter: 30 mm
• Rod diameter: 14 mm
• Adjustments: rebound, double compression (low and high speed), hydraulic preload and height
• Factory settings: low speed compression 24 clicks, high speed compression 20 clicks, rebound 24 clicks, high speed extension 20 clicks, hydraulic preload 12 mm = 24 clicks, spacing 8 mm
• Version / variants: available in versions with compact hydraulic preload (e.g. XXZ31V2)

Designed to provide fine-tuning of behavior — stance, support, and stability of the rear end — the XXZ81V2 is aimed at riders who want to refine their machine's setup and experience better feedback at the handlebars during angle changes and accelerations. Common compatibilities: APRILIA TUONO 660 (2023-2024) and FACTORY versions.
