You're absolutely correct. Your explained age and bike power factors are the same in Windsor, Ontario. Yet a town over, in Amherstburg, Ontario, I was told that a motored bike's power is of no concern. All the police ask is that anyone who rides such a vehicle be at least 16, wears a helmet, and goes no faster than 50 KMs hour. I responded saying, "You police are great. I love this town!" I always loved the town, even before this bike thing. Not even a DOT rated helemet is required! But in Windsor it is required.
