The Grunt reinvisions, what you thought possible before. Go anywhere, Climb almost any hill, and expand your riding adventure like never before.  Hear that? That's the peacefulness of a Gates Carbon Belt Drive system, making the new Grunt EVO a chain-free environment. EVO has a narrower frame than its predecessor and the redesigned swing arm lightens the weight while adding a sportier appearance. We also mounted the electrical components to the frame for a more minimal look. The Grunt Evo is the perfect weekend adventure vehicle whether you are a recreational weekend warrior or demand a working farm tool the Grunt EVO delivers.
