All Balls Tapered Headrace Bearings

On models with tapered original steering head bearings All Balls heavy duty tapered bearings function as a high quality direct replacement.

On models that originally took ball-type steering head bearings, All Balls tapered bearings can be used as an upgrade. Ball-type bearings have tiny points of weight-bearing contact area, which means that ball type bearings have a much shorter lifespan than a tapered bearing, where the weight is spread across the long surface of a cylindrical roller. In addition, tapered bearings are far easier to install and do not have the issue of over or under-tightening of the original uncaged bearing design which could cause handling problems.

All Balls tapered steering head/headrace bearing kits contain the upper and lower bearing and seals where appropriate.
