Reviews
Wilbers Zero Friction polished two stage progressive fork springs for the K75S have an inital spring rate similar to stock at 5.5 N/mm, but then they ramp up to 8.0 N/mm as they compress to help resist chassis rocking and nosedive under brisk riding or heavy braking. They also help to resist bottoming or using up stroke too quickly during high speed compression events over larger bumps.
You will need one bottle of 10 wt fork oil.
Air chamber is 170 mm for normal street use. Air chamber is measured with spring out and fork compressed and fully bottomed out. Pour in fresh 10 wt oil until the oil level is 170 mm from the top of the tube.
Not for Showa forks which were used 08/91-on.
