The amount of "pullback"' on stock bars is @ 14" thus no excessive slack for taller risers. I replaced my stock bars with a 8.5" height, 34" wide and 7" of pullback and in turn I got plenty of slack due to the pullback. Not saying to switch bars but just a example of what the pullback spec can do to influence the fitment. This happened 2x on the VT1100C Spirit and the Valkyrie using these bars and in return greatly improved low speed handling on both bikes because of the "buckhorn" style wrist placement sucks. I'm a 5'11" normal build person.
Here's a listing for stock MC handlebars.

Very solid set of bars. The stock risers covered the knurl also compared to the skinnier VT1100C risers.
