Product Description : 

Since 1975, Bitubo has been the ideal solution for those looking for the best from their machine: performance, comfort, driving precision, and above all, the quality of an excellent product, continuously developed in constant collaboration with advanced research centers, tested and developed with fatigue and destructive tests, both in software and dynamic simulations.  Bitubo products are used in WSBK, BSB, CIV, CEV, IDM, and many other national championships around the world.

Bitubo's XXZB1 Race only pressurized Rear Shock incorporates the latest feedback from top level riders in WSBK, BSB, CEV, and other championships to bring you the best value in performance.  The goal?  To offer the rider excellent front rear end stability, thanks to perfect control of deceleration forces even under the most extreme braking; to increase grip entering and exiting a curve thanks to immediate hydraulic control; more uniform tyre wear thanks to instant control of cornering loads. All of this gives the rider the best control under braking, even at extreme lean angles, and in the most challenging corners on any track.  Includes installation instructions and settings guide.
