An aluminum front steering hub carrier that further enhances the cornering performance of YZ-4SF2 on high grip road surfaces such as carpets or artificial grass.
Comparing with standard caster angle (8 degrees), the caster angle of 6 degrees is specialized for high grip road surfaces.
This change would reduce the entanglement at the exit of the corner and the feeling of remaining rudder, which would result more linear operation feeling.
The improved stability makes it easier to maintain the rhythm between corners, and the aluminum rigidity and weight increase the feeling of grounding, this option may improve overall time.
