Probably round about 2000, the UK police scrapped all their STs because they said they were inherently dangerous after at least 2 cops were killed after experiencing tank slappers and the investigators said it was the bikes fault whilst Honda UK said it was probably because of uneven weight distribution of police equipment.
That problem involved only the ST1300, not the 1100. Both officers were killed on 1300's. The 1300 appeared over there in 2002, we got it in 2003, so the accidents were post 2002. There are still some police 1100's in use in Britain and elsewhere, as you can sometimes notice them in news stories from across the pond.
