Steering head bearings

[VW_NUT]

I am in the process of rebuilding the suspension on Hangin_biposto's bandit 400 & have a question about the steering head bearings.

I checked the fische on bikebandit.com and can't find the steering head bearings on there.  Anyone here know how much they go for?  Also are they a standard size that I can get from a bearing house?

I'd call the zuki dealer, but its monday & they are closed.

aftermarket tapered bearings are usually cheaper
