What each year's complaints describe comes from reading their text. These are counts, not rates: there are no sales figures per motorcycle model year. A complaint is not proof of a defect.
Popular years get more complaints just because more were sold, and newer years have had less time to collect them. There are no U.S. sales figures by motorcycle model year, so these are counts, not rates.
