Fork Spring Upgrade Kit YSS for BMW C400X

Better road contact, safer handling with the YSS Fork Upgrade Kit.

The YSS Fork Upgrade Kit includes a stiffer fork spring as well as an adjustable fork tube cap.
For vehicles with conventional forks, a fork valve is also included.

For vehicles with upside-down forks, a fork valve cannot be installed for technical reasons, so it is not included in the delivery.

The fork tube cap allows for fine adjustment of the fork preload from the outside:
By turning the adjustment screw, the pressure and thus the preload of the fork spring is increased.

YSS delivers this kit vehicle-specific as a complete set.
