The federal agencies allege that Harley-Davidson manufactured and sold about 340,000 illegal devices, known as “super tuners,” that, once installed, caused motorcycles to emit higher amounts of certain air pollutants than what the company certified to the EPA.
Similar to the “defeat devices” Volkswagen used to cheat emissions tests, these super tuners alter a vehicle’s emissions controls and are prohibited under the Clean Air Act for use on vehicles that have been certified to meet EPA emissions standards.
Harley-Davidson also made and sold more than 12,000 motorcycles that were not covered by an EPA certification that ensures a vehicle meets federal clean air standards, the agency says.
Under the settlement, Harley-Davidson will stop selling the illegal aftermarket defeat devices in the US by Aug. 23. The company will also offer to buy back all such tuners in stock at Harley-Davidson dealerships across the country and destroy them.
Additionally, the company will pay a $12 million civil penalty and spend $3 million to mitigate air pollution through a project to replace conventional woodstoves with cleaner-burning stoves in local communities.
