No "particular" bar it's just a case of overall length. There will be many options that don't require new cables. And many that do.
As but one example I've got the Wild1 "mini apes" on my Road King. The name notwithstanding they don't look like like ape hangers. I don't really care for tall apes. These bars look good, feel fine, good wrist angle and didn't require longer cables than stock.
If the Harley bar is 1.25" even at the riser mounts you'll have another change to make when swapping the bars. Most bars (even 1.25" aftermarket bars) are only the standard 1" at the riser mounts. So you'll be changing the risers also. To use the more common 1" risers. That's not a big deal. They aren't even very expensive. Plus it's a great opportunity to change the old riser bushings while you're doing it. Be sure and use a one piece top clamp when you put it all back together. Makes for a stronger mount.
