One Crazy Summer

Kawasaki GPZ??? With that colour scheme I think more likely one of the early Honda CBR models. Non... Effectivement Kawasaki GPZ, 600 ou 750 I wondered why I couldn't get the front fender to match. Here is what it is - a 1985 Kawasaki GPZ600R Ninja. http://www.motorcyclespecs.co.za/model/kawasaki/kawasaki_gpz600r%2085.htm

Yes, Kawasaki GPZ 600R or 500R

Z 650 LTD,custom variant of the touristic Z 650

There never was a Z650 LTD, just the D model (SR) or the CSR that had spoked wheels. That bike is a 550 or 750.

Kawa LTD

Same bike? /vehicle_115569-Kawasaki-Z-650-LTD.html

I see a 1965 or so Plymouth Valiant in the background. As for the bikes, you're on your own. The one on the right is a Harley. The other three are all Kawasaki 1000s - the middle two are Z1000 LTDs from about 1977. On the left is one of the sporty versions from about the same era The red don't resembles a Z1 R??? That fairing set up is very distinctive but I haven't found a reference to it yet. It maybe aftermarket. The factory ones were much more angular by about 1982. la moto de droite n'est pas une Harley mais peut être une Yamaha Virago

In order from left to right. 1982 Yamaha XJ550RH Seca 550 1981-82 Kawasaki KZ550 LTD 1985-86 Yamaha XJ700 Maxim 1984-85 Yamaha XV700 Virago.

Honda CM 750 F??? Kawasaki Z 650 LTD ?? One of the same Z1000LTDs seen in another pic.

Now that I see the tank it is a 1985 Yamaha XJ700N Maxim.
