78 KZ 650

I have a 78 KZ650 I am putting back together (took it apart 20 years ago). I need a new rear tire but dont like any of the options. I want to put a sport tire (lower profile than stock). My point is:

Does anyone know of wider wheels that will fit on the 78 without alignment issues?

I am willing to change the forks if necessary.

Thanks in advance!:woohoo:

metzler lasertec 130/70 H 18",might be little wide for stock rim but its a little shorter than the normal 80 series tires

Here's what some other 650 riders are running:
