The YFZ450X is flawed from the factory as the front end does the exact opposite, the caster increases when the front end compresses and the caster decreases as the front end extends. The new upper a-arm caster bracket elimates this problem by keeping your caster at the location you set it at upon installation, it will make a noticable difference in the handling of your ATV, guaranteed.
