Rear shock Bitubo XXZ B1 for BMW S 1000 RR HP4 13-14

Derived from the pluri-victorious XXF, the Mono XXZ, so far reserved only for our Official Teams, is confirmed as technologically at the top, presenting itself with a totally renewed design bringing with it many technical innovations, such as the 4 adjustments: compression and extension at low and high speeds, with new settings designed to give the rider the best feeling possibile.

Inside it is renewed with technical solutions that optimize the smoothness of moving parts, improve the damping coefficient and increase the stability at high temperatures, without forgetting the use of light materials to lower the overall weight.

The Ø 14mm rod increases smoothness while the piston of Ø 30mm reduces the masses of fluid in motion for a faster response to stress, particular attention was dedicated to maximize the sensitivity and accuracy of adjustments.

XXZ is designed to reduce inertia and ensure an immediate control of suspension oscillations.


TARGET is to give the rider precise control and increase maximum grip, as well as even tyre wear which is  provided by the immediate damping force. This gives confidence to the rider in the corners even at extreme lean angles, during fast direction changes and under hard  acceleration.

At the same time it provides excellent stability of the rear, even under the most extreme braking, regardless of the track  or surface condition.

TECHNICAL FEATURES
Dedicated to the most demanding of riders, it is the most extreme version of our XXZ, the piston rod is treated to reach a stable performance over time.


THE PNEUMATIC SPRING PRELOADER, previously only available for official teams, is now available to everyone! Precision, speed and lightness are the essence of this new adjustment device. It works through a rechargeable tank with quick connection, available on demand.

DLC COATING of the piston rod to reduce friction, therefore providing an immediate damping feedback during suspension oscillations.
