ABSTRACT:
A motorcycle whose front end has a coil-over shock disposed within the head tube and telescopic forks which include linear bearings riding between flats on the outer face of the inner fork tubes and flats on the inner face of the outer fork tubes. The linear bearings ride on hardened steel races, enabling the fork tubes to be e.g. aluminum. Using an odd number of linear bearings in each fork prevents having two linear bearings at 180° opposition which would increase sensitivity to manufacturing tolerance stackups, preload, and the like.
