Kit d'amélioration de fourche Triumph Bonneville -'15 YSS

The YSS fork valves are inserted between the piston rod and the fork spring by changing the fork oil flow in both directions. They turn a conventional fork ensuring 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.

Thanks to the fork spring preload plugs it is possible to further refine the adjustment of the elastic thrust of the fork: adjusting them increases the pressure and therefore the stress of the fork spring.
