Product information
Adjustable Rear Mono, Integrated Reservoir: hydraulic spring preload, double rebound, double compression, wheelbase 368 +4 -4, Red spring
Code: BW051XXZ31
Bitubo XXZ31 rear shock absorber specific for BMW S 1000 RR motorcycles (model years 2019-2024). It is a high-end racing component designed to offer exceptional control and driving precision.
It confirms itself as technologically top-notch, featuring a completely renewed design with many technical innovations, such as the 4 adjustments: compression and rebound at low and high speeds, with new settings designed to provide the rider with the best possible feeling.
Internally, it renews itself with technical solutions that optimize the smoothness of moving parts, improve the damping coefficient, and increase stability at high temperatures, without forgetting the use of lightweight materials to reduce overall weight. The Ø14mm stem increases smoothness while the Ø30mm piston reduces the moving fluid masses for a quicker response to stresses, with particular attention given to maximizing the sensitivity and precision of adjustments. XXZ is designed to reduce inertia and ensure immediate control of suspension oscillations.
The GOAL is to provide the rider with unprecedented driving precision and increased grip, along with uniform tire wear thanks to the instant control of the forces at play. This gives the rider maximum support in curves even at extreme lean angles, quick direction changes, maximum confidence when opening the throttle on all types of tracks, and perfect rear-end stability even in the most violent braking.
This shock absorber, derived from the multi-victorious XXF model, features several advanced technical solutions to optimize track performance.
Adjustments: It offers complete and independent control over four main adjustments, all positioned at the top for greater ergonomics:
Compression (high and low speeds): 20 clicks for high speed and 24 clicks for low speed.
Rebound (high and low speeds): 24 clicks for rebound and 20 clicks for high speed.
Hydraulic spring preload: 12 mm adjustment with 24 clicks.
Variable wheelbase: Adjustable up to 8 mm (+4/-4 mm).
Technology and materials:
High-strength steel body and lightweight aluminum alloy components to reduce overall weight.
Ø14mm stem to improve smoothness and reduce friction.
Ø30mm piston to reduce moving fluid masses and ensure a quicker response to stresses.
