Welcome to KZR! Where did you find the KZ700? That should be a rare motorcycle in the Netherlands (and Europe).
Not really a spectacular story, just came by on a marketplace. I would've wanted a Z1000 ofcourse, but that was not in my student budget.
Indeed the 700 was (as far as i know) never officially sold in Europe. It was special to the US to circumvent the tarriffs on larger foreign bikes. As did a lot of other japanese manufacturers.
There were a lot of used bikes imported to the Netherlands (and maybe Europe in general) from the US in the past.
My registration also states 1987, but as far as i know, the Z700 was a 1984 only bike.
I guess the registration procedures weren't that thorough back then and it was brought into the Netherlands after 3 years.
It also received a 750cc cylinder bank somewhere in it's life, so it isn't officially a real kz700 anymore.
