Bitubo arrière XXZ31V2 Shock absorberRef : BITU00091A / 1115077

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 Rear Shock XXZ31V2 — Manufacturer's reference: A0043XXZ31V2

Derived from the competition developments of the XXF/Mono XXZ range, this BITUBO rear shock XXZ31V2 offers a technical evolution designed for demanding roadsters. Engineered to provide fine-tuning of the rear behavior, it combines a Ø30 mm piston and a Ø14 mm shaft to reduce the mass of moving fluid and enhance sensitivity to inputs.

The hydraulic core features four distinct adjustment pathways: compression and rebound at both low and high speeds, plus an adjustable hydraulic preload. These adjustments allow for precise tuning of the stance, compression response, and rebound according to your riding style and road conditions.

• Piston diameter: 30 mm
• Shaft diameter: 14 mm
• Adjustments: rebound, double compression (low and high speed), hydraulic preload, height adjustment
• Version XXZ31V2: compact hydraulic preload adjustable over 10 mm (= 20 clicks)

• Low speed compression: 24 clicks
• High speed compression: 20 clicks
• Rebound: 24 clicks
• Standard hydraulic spring preload: 12 mm = 24 clicks (see version XXZ31V2)
• Spacing: 8 mm

Suitable for high-performance roadsters, the XXZ31V2 is particularly compatible with APRILIA RSV4 (2017 models 1000 cc). It targets riders seeking precision, multiple adjustments, and better rear control without making unverified technical promises.
