There’s no real ‘mods’ on police bikes really, the r/h switch cluster obviously used to control police lights and sirens that people now use to control extra farkles.
Some of us still have lights and sirens, me and Brock.
Police bikes have a slightly different wiring loom because of the additional lights etc, which are only decommissioned by removing the lights and siren box, usually the wiring pretty much remains.
What kind of mods are you looking to add?, you can purchase a quartet harness which connects to the wiring loom and allows extra connection for upto 4 extra power sockets I believe.
We have uhf radios, heated grips, extra lights, intercom systems, the sky’s the limit for add ons.
Yes it’s true on the 1300 we can leave our panniers unlocked which helps, there’s a few that use cut down keys in volume type knobs so the key remains in the lock and will not start the engine due to its reduced length. A nice little mod.
Has your bike been converted to a dual seat or are you running with a solo seat and pod?
