The Bell MX-9 Adventure Motorcycle Helmet protects your most important tool–the one sitting atop your shoulders. This dual-sport helmet is comfortable on-road or off, and features limited-edition Filson logo graphics. Bell has been an industry leader in head protection for high-speed motor sports and recreation since Roy Richter built his first helmet in 1954. Developed with the help of a veteran U.S. Navy pilot, the early models were used extensively in California’s hot-rod and road-racing scenes. In 1955 a Bell helmet saw its first action in the Indianapolis 500, and in the decades since, Bell has become the first name in helmets for motorcyclists and racers.
