Yamaha introduced the ATV industry to Electric Power Steering (EPS) in 2007, and the 2014 Grizzly 550 uses essentially the same system. Possibly the greatest safety enhancement ever injected into the off-road industry, EPS makes encounters with rocks, ruts, roots, and other hidden trail obstacles easier to negotiate by preventing the handlebars from being ripped out of the rider's hands. Four wheel drive typically requires more steering effort from the driver, but EPS helps offset the energy required from the rider and thus, helps prevent premature rider fatigue. The Grizzly has a narrow body and a tall 10.8 inches of ground clearance, which allows the Grizzly to negotiate even the tightest, gnarliest trails with ease. The four wheel hydraulic disc brakes worked exceptionally well, and a parking gear eliminates the need for an emergency brake.
