There are plenty of people such as yourself, who navigated the inherent risks successfully. Unfortunately there are also plenty of people, who don't. It was terrible when I was that officer standing at the front door of a parent at 2:30 am. Certainly, it was devastating for the parent(s), but, it also is incredibly difficult on the first responders.
No one, has told the rider he can NOT have the bike, they are simply advising of the inherent dangers in having one at that age. Although, realistically, there is ZERO need for a litre bike on ANY road in Ontario. There is NO legal use of it, anywhere near it's potential. Unfortunately those who don't navigate, the dangers, are the first and the last person to realize it. By the time they realize it, it is too late.
