A re-entry motorcycle rider is a politically correct name for an older biker who returns to motorcycling after a lengthy absence. Based on an analysis of U.S. Department of Transportation (DOT) traffic statistics, the IIHS determined that age 50-plus riders sustained fatal injuries more often than younger riders. Re-entry motorcycle riders require safety training before they ride a bike again. Their lack of recent experience and control often puts them at greater risk of injury.
