Vega Helmet Corporation (Vega) is recalling certain motorcycle helmets, model XTS, sizes L, XL, and XXL manufactured from May 2011 through October 2012. These helmets may fail to conform to the impact attenuation requirements of Federal Motor Vehicle Safety Standard No. 218, "Motorcycle Helmets." By wearing a noncompliant helmet, the user may not be adequately protected in the event of a crash, increasing the risk of personal injury. Vega will notify dealers and post public notices about the recall. Any noncompliant helmet will be replaced, free of charge. The recall is expected to begin during late January 2013. Owners may contact Vega at 1-425-656-0683. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
