I have an 06 Fat Boy and have been considering swapping the stock bars. I don't want to change the cables at all. I have read some about people changing to heritage bars but I was wondering if anyone has changed to Street Bob bars?

 

I like my khrome werks sweeper bars very well. They are similiar to Heritage bars but have a curve to them that makes them very comfortable and stylelish. Check'm out @ khromewerks.com

 

I swapped the stock bars on my Standard with Heritage bars and short risers (1.5") with no changes to cables. The cables probably wouldn't fit with the stock risers.
Not sure off hand if the knurl on the dynas are the same as the softail, check that first, if similar I would guess the street bob bars aren't as wide/high as the Heritage bars.

 

I think the street bob bars have a higher rise.

 

SB bars are definitely narrower and higher than the Heritage bars.
