The KZ1000 is a great bike. I rode one once, when I first started motors (just to see what it was like).
All police bikes are beat to shit. We ride clutch half in/out, we constantly drop them, we are always going into red rpm's. The only bonus is that you know it's getting a regular service.
Another bad thing about police motorcycles. Until Honda jumped into the game, all the bikes were made in three different shops. First the dealer built the bike... then they send it to amother shop to put in the emergency lights... then they send it to another shop to put in three radio equipment.... God save you if you're having any additional equipment (RADAR?) put in.... this gives about 12 miles of wiring inside the bike, that no one can ever decipher, and everyone blames any electrical problem on the "other guys".
Honda and BMW now make complete bikes in shop (BMW still outsources the radio).
