My wife had that problem with her current bike (a Dyna). You may find rolling your bars a bit closer to you will help. Think of it as dropping your elbows a little.
The proper arm position for any bike involves having your elbows at or slightly below the level of of the handlebars… So that your forearm is parallel the ground (or bent slightly upward). This is the position in which you have the most control, and the least resistance, where the bars feel lightest and respond most accurately to your steering inputs.
