It’s not a motorcycle, but some old timers may remember these:
I’m 26 myself, and I had one when I was 16 because I thought they were cool as. I sold it to move on to a 125 and have been looking for it ever since. I settled on the above example as it’s as close as I could get, same year, same colour and spec. My original didn’t have the expansion chamber and I took a trip to wales to get a dual seat and mag wheels for that one.
Edit: It’s a 1972 by the way.
This one may get a 70cc kit and big carb at some point.
