I bought a ST1300 from Manhielm Fowles a few years ago and changed the seat over to a Corbin twin seat. The WA Police hierarchy decided that motorcycles were not the way to go and down sized the fleet, so they off loaded quite a few of them, mine had less than 6,00 kms on it when I bought it
Causeway Honda in Perth got caught with a few extra ST1300P Hondas when the police changed their mind. They ended up converting these bikes to civilian bikes by changing them to a twin seat, putting on a genuine top box and advertising them for $19,999. The bike in the photo looks like one of the ones from Causeways.
A couple of years later the W.A.P.D. realised their mistake and went back to ST1300 Hondas and are only now changing to FJ1300 Yamahas because they can't buy any more Hondas.
The Police bikes are different that the civilian models, the easiest way to tell with Hondas is the frame No ST1100P/ ST1300P . CB750P P=Police!!
As said before the switch gear is different, bonus because you can use them for your accessory switches, spotlights etc. They have an upgraded rear shock and are rumoured to have a thicker frame. The rear frame is slightly different because it has an extra bracket either side to support the Electronics mount plate, I cut the mounts off when I fitted my Corbin because it fouled the bottom of the seat.
I am told that they also speed limited the Police ST1300s to 198 KPH ( not that I have ever tested the theory, and this was done because the UK Police bikes had different pod on the rear to house the radio/ blue light controls etc, the shape of the pod (and possibly the weight of the electrics) caused instability at high speed which led to some fatalities.
I have not been able to find out how to remove the speed limiter, even the local Honda technicians are not clued up.
