Does this measurement go for all honda scooter motors

51mm=84.6cc (85cc to be generous

) on a stock crank... All those measurements would be on a stock elite crank (41.4) except for the 55mm bore, which is 125cc with a 52.6 crank.

Yes sir

808 is 100% correct

Are there any bore sizes that I don't have listed?

54mm stroker bores are fairly common, 120cc with a 52.6 crank.

Then there's the wonderful world of small strokers, 50/51 cranks teamed up with all kinds of stuff (50/51/54/55), and the new 130 stroker (56mm bore 52.7mm crank).
