COMPLETE PRESSURIZED FORK CARTRIDGES BITUBO EBH59 (+ 15 MM) PER YAMAHA R1 2020-2024

Bitubo EBH series fork cartridges made with a series of innovative systems such as the already known FPS, EC, LC and the new OPC (over pressure control) overpressure control system.

On the top cap there are all the adjustments, spring preload, rebound and compression which are distinct in the two cartridges.

They guarantee an excellent feeling thanks to the high damping coefficient which, even from very low speed, controls the excessive sinking of the front end from the very first moments of braking.

Technical features:

- Hydraulic control with FPS system ( Bitubo patent) piston Ø27mm in ergal

- Ø10mm pumping rods with anti-friction surface coating

- Mechanical limit switch with polyurethane pad in NBR

- Cr-Si steel springs, with heat treatment, settling process and final shot peening

- Fork top cap with integrated spring preload adjustment

- Independent adjustment of compression and rebound damping

- Coaxial compensation chamber ( Bitubo patent)

- Ergal cartridge body with anti-friction surface coating

- Hydraulic lubrication separate from sliding lubrication

- Pressurization force control system

LC: This product has a high percentage of special light alloys and weight-optimized details, with the aim of achieving the maximum possible lightness.

FPS: Innovative damping system created to have immediate control of the oscillations of the fork while avoiding any phenomenon of cavitation in the internal fluid. The system is pressurized with low pressure gas. The cartridges are asymmetrical: one controls the compression phase, while the other controls the extension phase. By placing the compensation chambers alternated at both ends, it is possible to obtain a very high damping coefficient already from a very low speed.

Package contents:

- Application specific assembly instructions where the viscosity, oil level and setting recommended by our R&D are indicated
- Keys for making adjustments and installation
- 1 liter of high smoothness oil
- 2 additional spare springs with different stiffnesses for different tuning needs are included in the package, in order to obtain the best control and highest performance.
