SF 750 bearing sizes

[harpmeister]

I have a SF1 that I picked up as a project and it is fitted with the double disc set up off of a SF2, according to laverdamania the bearing size for the front wheel is 17 x 40 x 12 but on changing mine I find that the bearings in the front wheel measure 20 x 42 x 12. which one is correct, can anyone throw any light on this.

It's the 20x42x12 (6004 - 2RS)for disc brake models - drum was the 17mm I.D. one - regards - Phil

Trust me Clem I may be thick but I'm not that thick, just checking if someone had replaced the front wheel with a dodgy one.
