Re: CBR929RR steering head bearing part numbers
I also figured that tapers were an upgrade. I even ordered the All Balls kit, but in the end didn't use it after getting some conflicting info on balls vs. tapers. Maybe it's BS, maybe it's not, but I am happy with how the bike is handling with the replacement OEM bearings.
The specific reasons I heard for staying with balls were:
1. Tapers are difficult to adjust properly--and you can't use factory preload torque values, because these are defined for the balls
2. Tapers have a larger contact area, which adds drag and takes away some steering feel.
On the plus side for tapers, they will last longer than balls if both are maintained the same (due to the larger contact area, the tapers will wear less). But I can stomach doing this job every 14 years...
