I didn’t really find anything on the subject, so I’m simply asking: what reasons have actually led to the Europe-wide limitation of the 50 ccm class to 45 km/h? Why exactly this value? Are there any concrete studies or justifications that have been and will be cited for this limitation? I’m seriously interested in the underlying safety philosophy. All the world is excited about this limitation, but I don’t necessarily want to create a thread in which I just want to know what philosophy is behind this concrete value. Greeting Michael
