allballs has a handy reference chart/application for compatible
steering bearings
next step in the process is stem length.
i am very close to a bolt-on swap to a early 90's GSXR inverted fork to 650.
it will require using two lower bearing and races from the 650
GSXR's stem length is very close but i have not confirmed just yet IF
it's all going to work.
