I've read that also but I don't understand why people say that. Sorry I can't give a better explaination. I guess the wider bars give more leverage, which to me isn't neccessarily a bad thing.
Just had my shoulder replaced last week hope it dosen't take too long before I can ride .
Put 575s on my 2009 flhx but it didn't help, had to have the surgery
Well I bought a used set of 508's today on Ebay, I didn't want to spend alot on a set of bars I had no idea would be helpful or not. I guess we will see after I change the apes for the 508.... thanks again everyone.....
I suspect you won't be sorry, I have ridden a few bikes with apes over the years and I can honestly say the 518's are far more friendly to me, the 508's should do as well for you.
