Henry Wolf has alleged that a four-hour ride on his motorcycle on May 1, 2010, left him with priapism (A persistent, lasting erection) that has lasted for 20 months, according to news reports.

Wolf is suing the North America branch of the firm and the seat’s manufacturer, in a product liability lawsuit in the California Superior Court in San Francisco, claiming the “negligent design, manufacture and/or installation of the seat” has caused the painful condition.
