DetailsBetter contact with the road, more safety with the YSS fork upgrade kit.The YSS fork upgrade kit includes a firmer fork spring and an adjustable fork tube cover.
For vehicles with conventional forks, a fork valve is also included.
For vehicles with an inverted fork, a fork valve cannot be fitted for technical reasons, so it is not included for these. With the fork tube cap, the fork spring preload can again be fine-tuned from the outside:
Turning the adjusting screw increases the pressure and therefore the preload of the fork spring. YSS supplies this kit as a complete set for specific vehicles.
