Motorcycle Recommendations UHF Radio

Need a little advise from all of the professionals here. Currently using a hand held with a helmet head set, but that does not work well. I have a 2012 BMW R1200RTP that I would like to install a radio similar to what Law Enforcement use. Looking for recommendations on a radio that can be remotely mounted, and would allow a blue tooth or hardwired helmet head set. Originally the bike was a former Sheriffs unit. Originally it had the radio mounted in the back with just the mike on the fairing. It also had a feature to blue tooth to the helmet. It was equipped with a PTT button on the right handle bar. Looking for something that I can use on this bike that wont break the bank.
I am not finding what I need online but figured someone here might know what I need.

Any recommendations would be greatly appreciated.
