Changes that would benefit motorcyclists and the industry would require political lobbying/power. We and the industry have zero power which is why, since 1990 and having seen governments from all three major parties -- NDP, PCs and Liberals -- we have seen little to no legislation or action to aid us in any way, shape or form.
According to StatsCan there are ~220,000 motorcycles and mopeds registered in Ontario. We probably could form a decently powerful political lobby to advance our cause(s). In 2015-16 there were "only" 124,000 "FTE" (full-time equivalent) teachers in Ontario. They wield significant political power because they're organized and politically (over)active. We could probably muster similar numbers of motorcycle enthusiasts (and spouses and significant others and friends etc) into a vocal bloc but we're too lazy, too disorganized and, as demonstrated in this thread, too busy fighting each other over stupid **** to organize effectively.
Of the 220,000 bikes there are fewer owners. I once had three ready to ride as have many on the forum.
Regardless there is a generic problem in that our roads were meant for transportation not recreation. They were not meant for stunting, racing, impressing chicks or any variation of playing "Look at me." Nor were the roads designed for roller blades, skate boards, Segways, hover boards, joggers or pogo sticks.
If you look at the teachers or other cultural / ethnic groups you will likely find a large degree of common goal that doesn't exist in motorcycling. I wish I had a copy of a M/C cartoon I saw where two bikers cross paths at an intersection, one on a dresser the other a bobber. Both give the other approving nods but once the other is out of sight they both do a thumbs down.
Name your argument. Loud vs quiet, sport vs touring, metric vs SAE.
Since the majority of cars are used for transportation there is a relatively small percentage of drivers that are openly annoying.
Since the majority of bikes are used for recreation there is a relatively large percentage of riders that are openly annoying.
If you add the performance potential of modern bikes to the testosterone of a young male rider you do not get a long term common goal.
Responsible hunters and fishermen / women follow sustainability guidelines unlike bush butchers who kill anything they can.
The bigger overall problem is that if everyone became as big a wet blanket as me the economy would collapse. We'd all be driving K car equivalents and be making our own coffee at home.
What if we ended up with blue plate restrictions on anything over 500 cc's?
