This bearing kit will fit swinging arm models without any modification.
Rigid and plunger frame models will require the inner corner edge of the frame relieved where the steering stem passes through the area where the outer race cup sits in the frame, there is a sharp corner edge which will need to be chamfered by a dremmel or similar tool to clear the inner bearing race when it sits in the outer race.

The taper bearings locate and support the steering head and front end weight, the bearings will give a light positive feel to your steering and improve the handling of the bike in general.
