I think people need to go up into Halton hills on a Saturday-Sunday morning and see how bad it is with middle aged men and women on straight pipe Harleys. They ride into town and make all that racket, then buy a small double-double for the local economy.
When the law kicks in, the HD crowd will likely complain and protest with LPSL, but they have nothing to stand on, because all proper studies prove loud pipes either just make noise, or put the rider at higher risk. Seems to me if one was really concerned about safety, they would buy a bike with less weight, actual cornering clearance and useful brakes, and maybe anything but a novelty helmet.
The number of these bikes I see dumped on the 403W/Linc on/off-ramps every weekend is pretty comical. Hamilton's Tail of the Gecko.
