The front bearing is 5, the rear bearing is 6. This is the rear bearing for that motor:

Hang on, I think the front bearing is supposed to be 6mm too. Boca lists it as a 5.

Here is the 6mm front from TKO:

Wow, that is good.
Just interesting if patent time is over, or they just breaking the law?

There have been bearings with offset races since the ball bearing was invented. Nova holds no patent on that. They were just the first to use them.

I have 2 novarossi plus 21-7FMS and 1 plus 21-7, I've had older TOP and Novas, RB's, modded many new and old nova 21's, 12's, older and newer ones like 3ct's & 353's plusII .12's and have never seen an skf bearing on them - and I look for them, that's my favorite bearing brand of all.
In fact I've never seen an skf in any engine - could it be this bad luck of mine?
