I rode my friends 2003 Grizzly 660 today to compare it to my 2014 Grizzly 550 with power steering to see how much harder the 660 would steer. To my surprise the 660 turns a lot easier at any speed than my power steering 550. I have read the old post about the power steering but was not expecting this result. I will say my 550 tracks a lot easier than the 660 without wandering around. The power steering light is not on but it makes you wonder if the power steering is really doing anything.
