It's not so bad as it sounds. For one, they have an official list (
Here's the pdf), which is full of Ninjas, Gixxers, CBRs, etc...
Second, registration in Quebec
includes the personal damages part of your insurance. That goes for all drivers, or anyone hurt by a motor vehicle.
Yeah yeah
There are a couple organizations that are lobbying for lower rates, or to at least make this ridiculous hike a little more justifiable. 4,000 bikers rallied last month outside the legislature, and that got a promise to re-evaluate the proposal to take driver education and experience into account.
If you ask me, they have two real reasons. First is that everyone who got any kind of license before 1970-something is allowed to drive a motorcycle -- so we now have lots of boomers getting bikes and they don't know what the hell they're doing, they crash, and they get a cheque from the govt for rehab. So they're doing this to convince people to give up their motorcycle certification.
Second is there are way too many squids on the road in Quebec. About once a week I'll spot someone popping a wheelie/lane splitting at 110kmh/riding on the shoulder. And many of the more sedate riders wouldn't know proper gear if they had their noses rubbed in it. (Yes, I'm talking about the guy in khakis and a t-shirt wearing the shortie helmet without the DOT sticker).
Third is when you say 'biker' in Quebec, most people think
thanks to our lovely biker gang war of the 90s. But that's not a real reason though -- that's just why the govt thinks it can get away with it without too much public fuss.
