Designed to be the most stylish, durable and functional handguards to date. The Sentinel guard is larger compared to the Star Series which, in turn, provides more protection. Snow and MX/ATV mounting brackets are 6061 aluminum, while the guard itself is made of two different types of plastic: stiff, two-piece spine for durability and a softer, colored body for flexibility. Handguards and mounts are sold separately.
