I would think that like any police vehicle that there has to be some performance modifications done. I was also wondering if the transmission gears were lengthened for highway purposes, and did they cam these things too? Some fxrp history, and specs would be great!! Thanks (1984 fxrp)

The early evo FXRP bikes (1984) were parts warehouse bikes, that is HD went to their warehouses and built a Genuine Harley-Davidson out of Genuine Parts for sale to the police markets.
For example, my 1984 FXRP had a 1983 dual disk front end (as did my friend's 1984 FXRP). There were other parts that were from various years (non 1984) that also differed between the bikes.
At a HOG Rally Q&A session I asked if there was a parts catalog for these bikes as ordering parts could be quite a challenge for the dealer's parts guys. The H-D Rep got back to me about a week later and told me there was no catalog as the bikes had been built from warehouse stock and for that reason no one knew what parts went on a particular bike.
I just adjusted to the fact that I needed to take the part in with me to the parts counter and NOT to allow the parts guys just order as if it were a regular 1984 FXR.
The bike had an enclosed chain final drive, with chain lubrication provided by an oil bath. If you didn't carefully assemble and install the rear drive, they would leak oil. If you were careful about assembly, they were really pretty dry. The primary chain used an oil mist lubrication system with a "dry" clutch.
My bike had many components with a "crinkle" black paint finish where on a standard FXR the part would be chromed. If the black crinkle paint was chipped on a part, you could tell they had just painted a chromed part.
I had also heard the rumor that the engine had modifications to the heads/cylinders for higher compression, but I suspect they used common parts. The idea was to sell these bikes CHEAP to police departments. Special components would have just made them more expensive. I think my FXRP's stock performance was the same as any stock FXR.
I believe later FXRPs had front/rear suspensions with more travel, special tires, etc.
