Kawasaki ZR-550 Zephyr
The 550ZR (ex Zephyr) is a nice bike in the standard (now called “retro”) styling.
Easy to handle, easy on gas, plenty powerful enough for the roads.
Unfortunately they’re not made for North American sale any longer;
but if you find a good used one and are considering purchase,
it gets my vote. email me for opinions.
The EL-250
is a smaller version of the same bike, which I also
liked while I had one.
