ARC (pr. ärk) is known by many as the “Factory’s Factory”. When the top Moto and Off Road Teams need custom top-secret designs, they hire Bob Barnett and his team in Santa Ana, CA to make the best parts on the planet. While these prototypes are not available to the public, the product that put ARC on the map is. Unbreakable Folding Levers. Everybody goes down, and no one wants to lose a race or ruin a ride day with broken or bent levers.
