General description

The ECH fork cartridge contains a range of innovative systems, such as:

Light Components:
This product is manufactured with a large proportion of special light alloys, which significantly reduces the weight compared to the previous YCE fork cartridge.
The adjusters for the diverse setting options are located on the upper end caps:
The spring preload is adjusted hydraulic, while rebound and compression damping damping are distributed across the two fork cartridges, making adjustment simpler and easier.

FPS = Full Pressure System stands for maximum efficiency and practicality. This innovative and patented damping system provides immediate damping and prevents cavitation of the internal fluid. The system is pressurised with gas at low pressure. The cartridges are asymmetrical: one controls the compression phase (compression damping), the other the rebound. With two alternating chambers at both ends, it is possible to generate high damping force even at very low speeds. The FPS system and its settings enable a wider range of damping curves compared to a standard hydraulic fork, especially at very low speeds.

EC = Easy Charger is the system for quick spring replacement without having to mount, fit, assemble the fork from the motorcycle. This system facilitates spring and damping changes for racing technicians.
It is possible to achieve a very high damping coefficient even at low speed, which controls excessive fork dive during the initial moments of braking.

AIM:
To offer the rider maximum stability on the front wheel, ensuring perfect control over the front wheel even during fierce full braking; improved grip when cornering thanks to immediate hydraulic control; more even tire wear thanks to immediate control of cornering loads. All this leads to maximum stability when brakeing, even at extreme lean angles and difficult corners on any track.

ADJUSTMENT OPTIONS:
- spring preload (hydraulic)
- compression damping (24 clicks)
- Rebound (24 clicks)
