To answer the question on the 2013 RT, I had a 2011, traded in for a 2013, and about the first thing I felt was the corning was soft, so I myself install the Ron Bar.
You got to get the bike up 2 feet before you can get the bar just right to it slide in. Getting the old bar was not so bad. Now I just traded up again to a 2014 and I removed the Ron Bar from the 2013 RT and I swear it was more effort getting it out then it was putting it in, not saying putting it in was all the easy until I figured it out. My 2013 bike, you could only get the RonBar to to slide in or out from the left side and you got to get it just right and it will slide perfectly in there.
So since I just got the 2014, I got the bar and for sure, I am putting it in soon. The bike is only 2 days old now.
