A Triple Tree, Triple Clamp, Steering Head, Steering Head Yoke, or Steering Stem is the name given to the entire basic steering assembly. Until around 1985, the majority of motorcycles, but not all, used loose ball bearings for their steering races. These bearings have upper and lower outer races that are tightly press fit in the frame, as well as a lower inner race that is press fit to the steering stem. The upper inner race is a little baggy.

They are double row bearings, but unlike traditional double row bearings, they do not have an inner ring.
Because of their configuration, they have a self-aligning feature. They have two rows of balls on the inner race and a common spherical surface on the outer race, the centre of which coincides with the centre of the bearing.
