Handlebar improves handling
Bigger bars might feel better at low speed, but they can be more touchy at high speeds. They 'amplify' your input.
Smaller, narrow bars feel 'tighter' or more stable at high speeds.
With a wide 34 inch handlebar move your hand 1 inch and you deflect the front wheel 3 degrees.
Three test bicycles differed only by handlebar configurations: racing (Maes Bend), standard, and high rise. The manoeuvrability of each bicycle was measured as subjects performed six tasks: circle, lane change, figure-eight, straight lane tracking, cornering, and slalom. Subjects were matched by riding experience and grouped by their familiarity with either race or standard bicycle. Analysis of variance showed that no bicycle times bicycle-familiarity interaction effects were significant in any one of the analyses. The performances observed on the bicycles with high-rise and standard handlebar configurations indicated they were not significantly different from each other. On the circle, figure-eight, and slalom tasks, performance with both the high-rise and standard handlebars was significantly better than with the race handlebars. The high-rise showed a slight performance edge on tasks requiring the greatest amount of manoeuvrability, while the standard handlebars offered more control at slower speeds and on tasks requiring stability in tracking.
Wider bars....as mentioned provide greater leverage. You’ll feel like it takes less effort to turn the bars as they get wider.
Hand & wrist angles are often overlooked. Find the bars which give you the most natural angles (and therefore grip) and you’ll ride with better comfort and easier control.
I’m 6-0 riding a 2020 RGL equipped with Factory 47 x 12” bars. I like this height as my arms, shoulders and hands all feel very natural. I could ride with 14” easily, but can’t see any advantage or improvement for myself.
Take a look at Khrome Werks website for their bars. They show all the dimensions for their bars, inclusive of pitch angle. I'm on my 2nd set (1st set got bent from an accident) of their mini apes. They have a 30.4 degree pitch angle for where your hand contacts the bars. Aside from T bars / drag bars, these have a relatively flat angle compared to something like beach bars. I find the flatter pitch angle allows better leverage.

You steer a bicycle, you don't steer a motorcycle at speed.
Push right handlebar grip on bicycle, go left.
Push right handlebar grip on motorcycle, go right.
The bars provide the leverage for the 'steering head' geometry! More leverage, more response.
You ride a bike with drag bars, and it feels tighter. You put apes on it, and it feels looser.
