Yamaha YZ 80 H 81 Tapered Headrace Bearing Set (By All Balls USA)
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.
30x48x13mm 25x43x11mm plus two seals

Care And Maintenance
Although bearings are subjected to large amounts of stress and are continually being used to fulfil various duties, they are precision made and typically last a long time (bearing failure is often due to improper installation and fitting). However high-mileage bikes and dirt bikes, which are exposed to a lot of mud and water, can become vulnerable and require attention sooner than expected.
