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 reference: K0070XXZ31. Drawing on BITUBO's expertise and derived from the XXF, the XXZ31 family offers a rethought suspension chassis for riders seeking fine adjustments and precise feedback on demanding roads and trails. Designed to optimize the behavior of the rear end, this mono-shock targets sensitivity, oscillation regulation, and consistent performance at high temperatures.

The XXZ31 stands out with technical choices aimed at reducing moving masses: 14 mm diameter shaft and 30 mm diameter piston for quicker response and increased fluidity. The entire setup focuses on better precision of adjustment clicks to refine behavior during entry/mid/exit of corners and during acceleration.

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

• Piston diameter: 30 mm
• Shaft diameter: 14 mm
• Adjustments: rebound, double compression, hydraulic preload, height

Designed for roadsters and demanding riders, the BITUBO XXZ31 offers a wide range of adjustments to fine-tune the feel of the rear end and adapt the suspension to riding styles and winding roads.
