The EPA DOJ have just come to a settlement agreement with Harley-Davidson, which sees the American motorcycle manufacturer agreeing to pay a $12 million fine for its Screamin Eagle “super tuner” devices. Also in the agreement, Harley-Davidson agrees to spend $3 million to mitigate air pollution (through a project to replace conventional woodstoves with cleaner-burning stoves in local communities), as well as to stop selling, buy back, or destroy any illegal devices that increase air pollution from the company’s motorcycles. While not quite the Dieselgate scandal that caught Volkswagen circumventing EPA emission standards, Harley-Davidson’s “super tuners” do provide an aftermarket solution for motorcyclists to circumvent the emission devices on their motorcycles.
