In July 2009, the Alberta Government changed the licensing requirements.
Prior to July 2009, a class 6 motorcycle license was required if:
However, new regulations came into effect on July 1, 2009. These regulations put Alberta more in line with other provinces in Canada. You now need a class 6 motorcycle license for your scooter if:
1) Your scooter has an engine displacement of more than 50cc, OR
2) Your scooter has a maximum speed of more than 70km/h
Basically, the provincial government eliminated the weight restrictions and upped the maximum speed, making it easier for riders of 50cc scooters to avoid getting a class 6 motorcycle license.
This means the vast majority of commercially available 50cc scooters in 2009 can be ridden with a class 7 or class 5 license.
Is this a good thing? Not really, as it just means there will be more scooters on the road with untrained riders. The Apocalypse Scooter Club highly recommends all riders or scooters and/or motorcycles to take a motorcycle safety course and obtain their class 6 license.
