Adjustable Pressurized Bitubo Cartridge Bh59 For Yamaha R9

In the world of Bitubo suspensions, the term 'increased wheelbase' related to the EBH59 cartridge indicates that the cartridge is longer than the original (standard) one of the motorcycle. Here's what it entails in detail:

Increase in length: The EBH59 version is designed to extend the total length of the fork, usually by about 15-16 mm compared to the standard measure.

Motorcycle geometry: By mounting a longer cartridge, the front of the motorcycle rises. This allows tuners and riders to have more room to slide the forks or modify the setup (geometry) to improve corner entry or ground clearance when leaning.

Racing Use: This specification is common in competitions (SBK, CIV), where it is necessary to vary the chassis dimensions beyond the limits allowed by the original components to adapt the motorcycle to different circuits or riding styles.

In summary, choosing the version with increased wheelbase is useful if you need a 'higher' front or if you want more freedom for millimetric adjustment of the chassis for sports use. If the customer is looking for a plug-and-play replacement that maintains the original heights, they should instead check the standard version (e.g., EBH09 or similar depending on the model).

The pressurized EBH cartridge contains a series of innovative systems such as the well-known FPS, EC, LC, and the new OPC overpressure control system.

Adjustable pressurized cartridge: preload, extension, compression + 1 lt oil

FOR YAMAHA R9 (RACE) / YZF-R9 2025>

These systems are the result of long development experience by our Research and Development department in collaboration with some of the best Teams that participated in the SBK, BSB, IDM, CIV World Championships.

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

The high damping coefficient from very low speed controls the excessive sinking of the front end from the very first moments of braking.

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

FPS: is an acronym that encompasses the maximum expression of effectiveness and rationality of this patented system. This innovative damping system was created to have immediacy of control of fork oscillations while avoiding any cavitation phenomenon 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 alternately at both ends, a very high damping coefficient can be achieved from very low speed.
