After a late 2010 introduction, the 2011 550 with EPS returns after being heralded by enthusiast magazines across the country as one of the best Arctic Cat ATVs ever produced. Arctic Cat’s Variable Assist Electronic Power Steering (EPS) allows steering assistance to the ATV before it even starts to move at idle. This is a huge benefit to conserving the rider’s input energy when in 4WD, and especially when the differential lock is engaged. Arctic Cat EPS will reduce the torque necessary to steer the ATV when changing direction with loaded racks or navigating tough obstacles like rocks, deep mud or logs.
