Hi Ralf,
the information I have shows the Kawasaki SG250 as starting
Frame SG-0001
engine SGE-0001
and says they were produced from 1964 to 1969?
here are some sites but the translation from japanese to english is somtimes not so good.

Engine number SGE-07820
There was a bike (meguro) parted out on ebay in the USA last christmas?
The bike was originally bought by someone at college as there first bike and crashed !
it was unused until sold to the breaker/salvage yard last christmas!
I bought the fuel tank off it which still had the Meguro badges on it and asked about the speedometer?
They sent me pictures of it and the speedo had "kawasaki" wrote in it as and the engine side casings also had the kawasaki badge?
Most of the parts were buy it now and nothing was cheap ,the tank costing $300 but lots of it did sell?
Hope some of this helps you
