All Balls Racing Fork Oil Seal Kit — BMW R100 RS (1976-1984) + 25 more
Product Details

Forks weeping oil down the tubes, or you've noticed dust building on the uppers above the dust seal — time to refresh the seals before the chrome scores. All Balls fork seal kits use OEM-spec rubber and exact-size dimensions so the fork action stays factory after the rebuild. Bushing-kit variants add the slider and leg bushings for a full re-build at the same drop. Includes copper washer, o-rings, and snap rings.

Kit fits the bikes listed below. Match your fork-tube diameter and bike year before ordering.

Kit contents:

  • 2x Fork Seal
