Model Fitment
For dirt-bike steering-head assemblies that match these cup, race and bearing dimensions. Compare all supplied measurements, seating profiles and the assembled stack height with your original components before ordering. Fitment is dimension-based, not universal across dirt bikes.
Install with the correct bearing lubrication and steering-bearing adjustment for your vehicle. After assembly, check that the steering moves freely without binding or excess play.
