Bitubo arrière XXZ31V2 Shock absorberRef : BITU00155A / 1115179

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 XXZ31V2 Rear Shock Absorber — designed by BITUBO, this mono-shock derives from the competition solutions XXF and is aimed at riders looking to refine the rear behavior of their machine. Designed for road/roadster use, it features a modern architecture and multiple adjustments to tailor the suspension response to riding style and conditions.

The XXZ31V2 combines a Ø14 mm shaft and a Ø30 mm piston to reduce the mass of moving fluid and improve sensitivity to inputs. Its design incorporates elements aimed at limiting internal friction and maintaining consistent damping under sustained efforts, while offering a compact hydraulic preload for quick adjustments.
