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 – Manufacturer Ref. MV003XXZ31

The XXZ31 is based on the technical foundation of the XXF and features a redesigned chassis and cartridge to provide fine adjustment of damping on powerful roadsters. Designed for demanding riders, it has four distinct adjustments (compression and rebound at low and high speeds) and hydraulic preload to precisely adjust the stance and behavior of the rear according to riding style or load.

Highlights:

• Piston diameter: 30 mm — reduces the mass of moving fluid for a responsive feel
• Rod diameter: 14 mm — improves operational fluidity
• Adjustments: rebound, double compression, hydraulic preload, and height
• Version XXZ31V2: compact hydraulic preload adjustable by 10 mm (≈ 20 clicks)

Factory Settings (Markers)

• Low-speed compression: 24 clicks
• High-speed compression: 20 clicks
• Rebound: 24 clicks
• Hydraulic spring preload: 12 mm = 24 clicks
• Spacing: 8 mm
• High-speed extension: 20 clicks

Ideal for enhancing rear sensitivity, grip, and cornering stability on sport bikes. Common compatibilities: MV AGUSTA F4 1000 (2006/2007) and derivatives.
