There are three types of ST1100/A/P models. They are antilock ST1100A, police ST1100P, and standard ST1100 model.
...
If you want an overview table for North American markets, just delete the police ST1100P model type for Honda model years 1993, 1995, 1996 and 2000 from the ... World overview table. That leaves 25 model type/model year combinations for NA, namely 13 standard ST1100s, 11 ABS equipped ST1100As, and one 2003 police ST1100P model. (I'll try to post said NA overview table here as a second attachment.)

Back now to the North American imports, it is often said that 1991 was the first ST model year for the USA. Less often you will hear that 1990 was the first Honda ST model year for Canada. While both of those statements are true, you will seldom hear the reason behind them, which is:
American Honda apparently asked Honda manufacturing in Japan to intentionally mislabel the first 1508 ST1100s built for the USA as 1991. I say mislabel because those STs were built from the same (aside from national differences) parts list as the 1990 Canadian ST1100 model, which was being built at the same time. So those 1508 ST1100s "should have been" labeled as 1990 also, but they weren't. (Later, Honda built an additional 1006 USA 1991 STs which were "true" 1991, as were all 1991 Canadian STs.)
This post is primarily
for North Americans.
Attached is an overview table of all the ST1100/A/P models imported into Canada and into the two USA markets (which Honda calls California and 49-state).
For such STs, Honda assigned a model year and put that year in
large digits on the VIN sticker. (I have also left the corresponding model year
codes in the table even though North Americans do not generally speak of those codes.)
The second column lists all ST1100A ABS, with the ABS II in the upper half of the table, and ABS I in its lower half. (
Red coloring is used there for the ABS type.)
The third column lists the Standard ST1100s. (
Green coloring is used for them.)
What I might call the fourth column is for the police model in 2003. (
Blue coloring is used for it, but there is only one police model, listed at the very top right of the table.)
The offerings for Canada and the USA were the same, with the following exceptions:
The one police model was imported only into the USA.
Canada received both 1990 and 1991 models; the USA received two 1991 models.
If I might simplify, the national differences were only that at least as much anti-smog stuff was put onto USA models as was put on Canadian.
Canada imported some green ST1100s, but I think they were built for Australia. I think they were all standard STs from the same model year. (To check, Aussie VINs start out JH2SC26U ....)
Zooming in now on model years 1992 through 2002, in the attached table:
* Two ABS models were imported per year (California and Canadian) thru 2002.
* Three standard ST1100 models per year (49 state, California and Canadian) through 2002.
* No police model during those years, or prior to them.
* By year 2001, American Honda had started calling the California, standard ST1100 the "50 state/California" model (or 50/California, for short).
