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. S0058XXZ31. Specifically designed for roadsters, this mono-tube shock absorber is derived from the XXF and features an optimized architecture to provide fine control of the rear end. Its design emphasizes the modulation of responses and the precision of adjustments for the demanding rider.

The XXZ31 offers four adjustment axes (compression and rebound at both low and high speeds) as well as a compact hydraulic preload (XXZ31V2 version available). Inside, the pistons and shaft are sized to reduce moving masses and improve damping fluidity.

• Main Features:
  • Piston diameter: 30 mm
  • Shaft diameter: 14 mm
  • Adjustments: rebound, double compression (low and high speed), hydraulic preload, height
• Detailed Adjustments:
  • Low speed compression: 24 clicks
  • High speed compression: 20 clicks
  • Rebound: 24 clicks
  • Hydraulic spring preload: 12 mm = 24 clicks (V2 version: 10 mm = 20 clicks)
  • Spacing: 8 mm
  • High speed extension: 20 clicks
• Common Compatibilities: suitable for SUZUKI GSX-R 600 (models 2004–2005) according to reference.

A technical choice for those looking to refine the rear behavior of their motorcycle, with extensive adjustment possibilities to tailor the rear end to riding style and chassis constraints.
