BITUBO XXF31 V2 Racing shock absorber 2012-2014 BMW S1000RR

In the shock absorbers for racing models market, the acronym XXF is a synonym for quality and technological innovation.

Development implied a reduction in overall weight and better response to the biker’s controls. Besides, the new ‘race ready’ set-up and upgrade of the adjustment of the inter-axis and the hydraulic spring-preload have proven to be key. As for innovation, damping ratio was improved along with stability at high temperatures. The 14-mm stem increases flowability, whereas the 30-mm piston reduces the movement of fluid masses. All these enhancements were aimed at reducing inertia and better controlling oscillations of the suspensions. Special attention was paid to the accuracy of adjustments, which are now available on the upper head.
XXF shock absorbers can be easily customized by replacing the XP compression and XS extension valves. Available set-ups are labelled on the body of the shock absorber.

When developing this racing shock absorber, the engineers' specifications were evolution and innovation. With a significant reduction in weight as well as an optimization of the set-up and the simplification of the setting options, an evolution was achieved. The interior of the damper is innovative. By using a 14mm piston rod, the friction could be significantly reduced and a 30mm piston reduced the amount of fluid to be moved. Together, this lowers the moment of inertia of the shock absorber and leads to a faster build-up of the damping even with a small spring deflection and low speed. The response behavior of the shock absorber has been significantly improved and thanks to the arrangement in the area of ??the damper head, all adjustment options are easily accessible. Even the length adjustment (max.
All functions of the damper have only one goal ... to give the driver the best possible grip and control and to ensure uniformly low tire wear. Only if the driver has absolute confidence in his chassis can he fully exploit the performance potential of his BMW S1000RR.

Compared to the standard version of the XXF 31 shock absorber, the spring preload is set using a hexagon screw directly on the damper head. This saves the handwheel and the associated connection hose.
