"I still cannot understand how these bikes especially this year and model would fetch buyers like that, its unreal."...
Simple, supply & demand, only so many made.
1976, something like 3000 here in the US, Z1's whoa different story worth more if as Jeff stated, original/non customized build.
Want a real rush, go search the Japanese sites buying and selling restored KZ's... These old KZ's are worth a mint over there, why not, country of origin!
Not to mention these old Z1's became King of the Road, for years mind you, opened up a whole new era of sport bikes world wide...
Hell, that's why most of us are even here, other then ball busting & Photo Chopping
, where as kids we were introduced to the KZ series of bikes...
Example, unfortgetable Kerker sound, wholly crapola, music to the ears... Every time I start mine, twist the throttle, I giggle like a school girl...
On the freeway at 6500rpm, twist her open with that 1.5" comp baffle, damn still gives me wood
...
Nothing better than that.... KAW Green baby!
