I am new here. My new rubicon 500 2015 is being delivered today. I opted for manual without ES. My last atv was a fourtrax 350 2003. I have never had power steering. I have read mixed reviews. I like to keep things simple and the less i have to fix down the road the better. I will be doing mostly trail riding. I just can stop thinking if i made the right call for me not getting it. I hate to not like the bike because of it. I would like to hear from more experienced people what there thoughts on ES are?
