That's a common Japanese practice, all bikes with plain bearings have that type of system. I believe it allows two things, a closer tolerance engine and less wasted material. If a crank is undersize somewhat or the register bores a little large, the bearings compensate. On the bikes you would read the coding on the crankcase and crank( probably rods too)
and use a chart in the manual to pick bearings. It has it's advatanges/disadvantages. That's not the case with most american V8s. Not sure if they junk undersize cranks/oversize bearing registers or just regrind the cranks. Typically US engines use standard undersizes as was mentioned by Ernie. Micro polishing helps gain more clearance if needed. I think there is a reliance on the bearing crush, as well, to take up some variances. Compared to the other procedure assembling the Ford engine is almost "tossing" them together.
