Product Code: Y0149XXFB1
Availability: Typically ships in 15 days
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.
Dedicated to the most demanding of riders, this is the most extreme version of the XXF.
PNEUMATIC SPRING PRELOAD: previously only available for official teams, is now available to everyone! Precision, speed and low mass are the essence of this new adjustment device. Adjustable via Bitubo's rechargeable tank
DLC coating on the piston rod: to reduce friction, therefore providing an immediate damping feedback during suspension oscillations.
The XXFB1 incorporates new technical solutions for improving the damping coefficient and increasing damping consistency at high temperatures. The 14mm rod improves sliding, while the 30mm piston reduces the mass of the fluid in motion. These improvements have produced a reduction of inertial forces, and thus immediate control of the suspension oscillations. Particular attention was paid to increase ergonomics and precision of the adjusters, which are all positioned on the upper portion of the shock for ease of access.
The target is to give the rider precise control and increase maximum grip, as well as even tire 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 at the rear, even under the most extreme braking, regardless of the track or surface condition.
