stearing stem bearing dimensions

[FT500R]

does anybody know the correct dimensions for the steering bearings of the Ft500.
I'm planning to change mine into conical ones, I've found an online store that sells a lot of bearings way cheaper than original honda parts, I only need correct measurements.
