On my 2013 FLHR I made a deal when I bought the bike,to add heritage style bars,so I got a we owe,and went on my way.I had heard a lot about the stock bars creating back/shoulder aches.But was surprised,it never really happened.I put 1,000 miles on with them.Changed then at the 1st service.I am more comfortable with the new bars,they give 3in.more pull back.However,I think I could have lived with the stock ones.
