The ECH pressurized cartridge contains a series of innovative systems: LC, FPS, EC

These systems are the result of extensive research and development by our R&D Department in collaboration with the best Teams taking part in the SBK World Championship and also in the British, German and Italian Championships.

LC= Light Components: this product is manufactured using special lightweight alloys, providing a considerable weight reduction compared to the previous YCE.

FPS= Full Pressure System exhibits the highest efficiency and practicality of this patented system. This innovative damping system provides immediate damping, while avoiding any cavitation of the internal fluid. The system is gas pressurized at low pressure. The cartridges are asymmetric: one controls compression, the other controls rebound. With two alternate chambers at both ends, it is possible to create high damping force even at very low speed.

All adjustments are located on the fork cap for ease of accessibility: the spring is hydraulically actuated, while rebound and compression are separate for each cartridge, simple and intuitive. Thanks to the possibilities offered by FPS, the adjustments available on the Bitubo ECH allow a wider range of damping curves compared to the a standard hydraulic fork, especially at very low speeds.

EC= Easy Changer: this is a quick spring replacement system and new exclusive cartridge dismantling system, which does not require removal of the fork. This system makes spring and damping changes easier for racing technicians. It is only necessary to modify one cartridge for compression or rebound.
It is possible to reach a very high damping coefficient even at very low speed thus avoiding front end diving at the first braking instants.

To offer the rider excellent front end stability, thanks to the perfect control of deceleration forces even under the most extreme braking; to increase grip entering and exiting a curve thanks to its immediate hydraulic control; more uniform tyre wear thanks to its instant control of cornering loads. All of this gives the rider the best control under braking, even at extreme angles, and the most challenging corners on any track.
