I know this thread is getting a bit old but I have a 2014 Street Glide special. so I thought I would give you my two cents worth...
I am 5'9" and have an elbow that does not extend all the way do to injury.
I replaced the stock bars with:
Yaffy Monkey bars: "PYO:MBBPW-12 C 12" Monkey Bagger Bar, 2014-Later, Pre-Wired, Chrome "
All my research said they come back the furthest, IF there is such a thing!
Any how, I like the bars quite a bit and they are WAY better then the stock.
As to the pull back they say 2" BUT it is limited and, I think most all the bars are limited!
The bars hit the tank (if you come back much) it just there nature and unavoidable so they stay at least near the 90 degree angle.
as for the stock mirrors they had to go with these, the bars are about center in them so perch mount mirrors are required.
The guy I worked with was very helpful and informative give them a call and ask your questions as this is likely true of any brand you end up choosing../
Thats my two cents. good luck
