Fork Oil for 1986-Present Front Forks

Typically, the fork oil is replaced with the forks on the bike. One fork at a time, the drain screw is removed and the forks are exercised to 'pump' the oil from the fork. Then the drain screw is replaced and a specific amount of fork oil is poured back into the fork.

The MoCo specifies the proper quantity of oil to use in the forks based on the fork design, ie., length of the sliders, slider travel distance, etc.

If the forks are removed from the bike and serviced, replacement of the fork oil is specified by the MoCo in two different terms. It is specified as to quantity (ounces) but is also specified by then measuring the distance the fork oil is down from the top of the slider tube. This measurement is taken with the fork spring removed and the slider & leg compressed together.

Both measurements are found below.


The MoCo specifies HD Type B or E (and respective equivalents) fork oil depending on year/model.
