Bitubo XXF31 Shock Absorber - Superbly Engineered




Racing Monoshock with hydraulic preload

Introduced in 2008, under constant development, the Bitubo XXF range sits at the top of current technology and leading the field at all levels of motorcycle sport
EVOLUTION of this shock has culminated in an overall weight decrease, using an aluminium body, which has always been the uppermost important feature in racing for better handling response and feel for the rider. In addition to new set-ups, even more race-ready, and an upgrade aimed at  better performance and adjusting simplicity of the length and hydraulic spring preload adjustment.
INNOVATION is in the internals of the shock, with new technical solutions for improving the damping coefficient and increasing the stability at high temperature. The Ø14mm rod improves the sliding friction, while the Ø30mm piston reduces the moving fluid masses. These improvements have produced a reduction of inertial forces, and therefore an immediate control of the suspension oscillations. 
Some particular attention has been paid to increasing sensitivity and precision of the adjustments, which are all positioned in the upper portion of the shock and readily accessible. 
OBJECTIVE is to give the rider the precise control and maximum grip increase, as well as even tyre wear thanks to the incredibly responsive force control. This ensures the best rider control in the corners even at extreme inclination angles, fast direction changes, maximum confidence under acceleration on all kinds of tracks and perfect stability of the rear, even under the hardest braking.
XXF is supplied with the following adjustments:
  • Low speed compression in  24 clicks
  • High speed compression in 20 clicks
  • Rebound in 24 clicks
  • Hydraulic spring preload range 12mm (in 24 clicks)
  • Adjustable shock length up to 8 mm.
