This column isn't much of a fan of the tort bar, yet wonders why litigators have not put the Hayabusa and similar overpowered bikes out of business. High-performance street motorcycles are socially irresponsible, and designed without regard for the safety of riders. Roethlisberger and others who buy high-performance bikes don't wish anyone harm, they're just looking for an ego rocket. But harm is what they cause, and legislatures should intervene. The Constitution says you've got a right to own a gun and to read a newspaper; firearms and materials related to First Amendment political, artistic and religious expression are the only categories of purchases with specific constitutional protection. Race a mega-motorcycle on a private track? Sure. But public roads are subject to public regulation. Our nation's laws do not confer any "right" to operate on public roads a high-horsepower bike, anymore than there's a "right" to drive a bulldozer down the middle of an interstate. It is past time the high-horsepower motorcycle was regulated off the roads. The intended use of these bikes is lawbreaking!
