It’s hard to explain how much power steering can improve your ride if you’ve never used it before. You simply don’t have work as hard and you don’t feel as much kickback from rocks and ruts. Even after a long ride - and I put more than 50 miles on the Grizzly 550 during the test day - you don’t feel nearly as tired in your shoulders and arms. Even your hands aren’t as sore because you don’t have to grip the handlebars as hard.
Power steering on ATVs is still in its infancy, but it improves the overall quality of the ride so much that you can expect to see it on a lot more vehicles in the very near future. It does cost a fair bit more (EPS adds $700 to the price of the Grizzly 550 FI), but it sure seems like money well spent to me and I don’t easily part with my money – just ask my wife.
