Hi Martin and thank you for your question!
To start off with, your frame number looks unusual. From all the abbreviations, one-xray-zero is not in the list and actually I would expect it to be "ST70-". According to my documentation, frame numbers changed to a more uniform code after 1981 into something like SC010*BM000001. Before that, I would expect something like: ST70-5000001
So one could assume that your bike is from before 1981. A 6-digit frame number is not unusual, as is a 7-digit number. If my information is correct, 6-digit numbers have been used in 1969, 1970 and 1971. So now we're down these three years.
There is a giant "but" though, and that is that your number is lower than 100000.
Can you tell me the following things:

I hope to hear from you and that this has been already helpful for you!
Best regards,

Any clue what year this is and possibly where it was made? The registration papers say year 97, but often here vehicles are imported second hand and the year is then then sometimes the year of first registration.
