Diameters outer 33.5mm, piston 15mm; valve height: 26mm. Ready for use; subsequent fine tuning can be done by changing the amount or viscosity of oil.
YSS fork valves turn a conventional fork a controlled feeling with improved road contact. CAD designed and hardened from extremely lightweight 6061 T6 aluminum with 65 Rockwell. Fine adjustable and suitable for almost all fork diameter: through an elaborate system of holes in the valve of the oil flow in the fork is changed so that the road contact and feedback is much more direct. The driver thus gaining security and feel for the road surface.
The YSS fork valve is inserted between the piston rod and fork sprin; therefore it is important to previously know the internal diameter of the dip tube and the bore in the piston rod. Depending on fork valve diameter used additional oil flow holes must be drilled in the piston rod. The fine-tuning of the fork valve is possible after installation with little effort: the crown has solved pulled the oil out of the fork and the fork valve are lifted upward, then can be tightened in increments of 2 turns or dissolved again with an allen wrench, remove the screw.
A very detailed installation instructions with pictures included in the delivery.
