Wayne, I'm just a messenger and maybe the message is incorrect, don't know.
All I can tell you is what Wild1 says about the 575s on their website: "GETS THE GRIPS 2" CLOSER TO THE RIDER ON FLHX, FLHT/C/U/K"
I can tell you that the 575s do get the grips closer than the stock bars - at least on my '07 cuse2 and my '12 cuse7.
Did a little research and looked in the H-D P&A catalog at their bars. Stock bars for '07 EG (non-CVO) are 55924-97 and are still listed in the P&A catalog showing 6.25 pullback. Stock bars for '07 CVO cuse2 (56007-04) are not listed in the P&A catalog but those for the '12 CVO cuse7 are - p/n 56036-08 with a 6.50 pullback. Even the bat wing reduced reach handlebar (56176-08) which moco says 'brings controls 2" closer to the rider for increased comfort' only shows 7.50 pullback.
So does the moco measure pullback differently? From the chart on the catalog it looks the same as Wild1. Perhaps a misprint? Jeez, I have a headache now.
