The video from a few years ago about the Johnny Pag bikes the police explained that they were using the bikes for general patrolling in the suburbs--quiet bikes which meant more anonymous. The JP bike (as seen in the video) was based on the Regal/JP Raptor.

As far as getting one of these? Maybe the company can sell you the bike as a rolling chassis sans engine? Or sell you the parts and you can stick them on a used Suzuki?
