33.5mm Outside diameter Piston diameter Hole in the fork: 26mm Overall height valve: 15mm The YSS fork valves transform the behavior of the conventional fork giving the rider a controlled feeling of better contact with the road. CAD designed and hardened from extremely lightweight 6061 T6 aluminum with 65 Rockwell.
Through an elaborate system of holes in the valve of the oil flow in the fork is modified so that contact with the road and feedback is much more direct.
The driver thus gains in terms of safety and perceive changes in the road surface.
A very detailed instructions with pictures are included in the delivery.
Application: on. off-road. racing and touring applications.
The fork valves are complete set for the respective fork diameter.
A subsequent fine adjustment can be made by the amount of oil or other oil viscosity.
Active ingredient: The YSS fork valve is inserted between the stem and the fork spring. Therefore it is important to know in advance the internal diameter of the immersion tube and the hole in the stem.
Depending on the fork valve diameters used additional oil flow holes must be drilled in the piston. This is described in detail in the installation instructions.
The setting of the fork valve is possible after installation with minimal effort. pulled the oil from the fork and the fork valve are raised upwards.
Then the screw can be tightened at 2 turns or loosened with an Allen key.
