Now, I'm going to chime in. The KZ1000P (Police) was made until 2005 or so. so mechanical parts are available. That motor was very popular with drag racers, so High Performance parts are readily available. The electrical system is weak (not as bad as a Suzuki GS1100 which is JUNK) It has many variants (LTD, GPz1100, Shaft) so retrofit/upgrade possibilities abound. It won't die because you can't get a camchain tensioner like a CB1100F. And the J isn't bad to ride. And, it was the base model of one of the three bikes I care about.
