I think it was mainly to do with the Japanese motorcycle license laws.
For a start, as part of their test, I think they have to lay the bike on it's side and proove they can lift it up unaided! Wonder how many GSXR1100's sold in Japan...?
Race categories undoubtedly had some bearing on the engine sizes, too.
But aren't they supposed to be bringing in similar limits for UK licenses?
If so, I'd have thought it doubtful that it will go from 125cc to 600...
EDIT: I believe it was a change in the Japanese license that killed off the 400cc market, too!
