Henry Wolf of San Francisco, California, filed suit in April 2012 against B.M.W. after a May 1, 2010, four-hour ride on a 1993 B.M.W. motorcycle with a ridged aftermarket seat (similar bike shown), allegedly left him with an unusual side effect: Wolf claims that he has had a an erection for 20 months. In his complaint, Wolf claims that his condition, called priapism in medical terms, was caused by "the ridge-like seat on his motorcycle, negligently designed, manufactured and/or installed by [the] defendants." Wolf claims that as a result, "He is now unable to engage in sexual activity, which is causing him substantial emotional and mental anguish," and that he is "distraught and distressed because of this." Wolf is suing for personal injury, lost wages, product liability and emotional distress. Wolf is also suing Corbin-Pacific Inc., the seat manufacturer.
