Bitubo arrière XXZ31 Shock absorberRef : BITU00148A / 1115168

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 XXZ31 Rear Shock Absorber - Ref. MV004XXZ31

The XXZ31 embodies the DNA of BITUBO suspensions developed for competition, offering highly adjustable damping for road and roadster use. Designed to refine the rear behavior, it combines a 14 mm shaft and a 30 mm piston to reduce moving fluid masses and improve sensitivity of reactions without unverified technical modifications.

Designed for the rider seeking precision and adaptability, the XXZ31 features four adjustment pathways (rebound, double compression, and hydraulic preload) as well as height adjustment to fine-tune the machine's stance. The adjustment clicks allow for precise tuning of the response during compression and rebound phases according to riding style and road conditions.

• Low-speed compression: 24 clicks
• High-speed compression: 20 clicks
• Rebound: 24 clicks
• High-speed rebound: 20 clicks
• Hydraulic spring preload: 12 mm = 24 clicks
• Spacing: 8 mm
• Version XXZ31V2: adjustable compact hydraulic preload 10 mm (=20 clicks)

• Piston diameter: 30 mm
• Shaft diameter: 14 mm
• Adjustments: Rebound, Double compression, Hydraulic preload, Height adjustment

Common compatibility: MV Agusta F4 1000 (2008-2009) and derivatives. Ideal for riders seeking a multi-adjustable shock absorber for better feel and precise rear management on demanding roads.
