Honda police models were the same the world over. The wiring was different to hook in sirens etc, which is the same the world over. The engine and speedos did vary according to country, which is detailed in the Honda manual (metric vs mileage, and different cams and jets to suit various markets). The police wiring did not make it to abs models, but the way the police modified the bikes has changed from the early days so the special wiring is probably not as important these days due to the electronics being able to be installed parallel to the OEM wiring. So the police used the Honda police version, as well as civilian models modified for police use.
The easy well to tell a Honda police model is the rats nest of wires in the rear duck tail, and the police switchblock, but this can be fitted to civilain models. I still have the black box that was connected to all that. All the extra wires filled a small box!
The Honda police models did not get any more performance bits or suspension upgrades (other than using 10W fork oil), but do use the pre 96 ABS forks rather than the civilian non-abs ones.
