Honda Z50J

The Honda Z50J refers to a popular motorcycle produced by Honda Motorcycles belonging to its Z Series family of mini bikes. It began production in 1973 for the European and Japanese markets. In its first few years of production, it was the same as its American counterpart, the Honda Z50A. But in 1978, when Honda dropped the Z50A from its American motorcycle lineup, the European Z50J continued to evolve until 1999. Fewer Z50J are being produced each year and are being sold only as limited editions.

Here is some info about monkeymodels which were sold in Finland. There may be some errors in writing due to my bad english.
