The handlebars do not want any weight on them. There is weight (downward pressure) and countersteering (forward pressure.) I think of a graph from math or physics class: Our downward weight is the Y-axis and our steering is the X-axis. We want 0 force on the Y-axis, straight down. The reason is that downward pressure diminishes the ability to steer the bike. Weight on the bars freezes them in place. When we then push them to steer, the weight presses against us. The long tank and lying down position naturally puts a lot more weight on the bars. We must fight against this design.
Sit on your bike. Lean forward and put your hands on the handlebars. Close your eyes and feel how much of your weight is pressing down. All of that is bad.
Remove your hands from the bars and sit back up. Squeeze your legs together on the tank. They will hold up your trunk weight. Reach forward and keep watching your hands. Drop them slowly, deliberately onto the bars. just touching the bars. Lift them, then lower them. Say to yourself "light as a feather, light as a feather." That, ideally, is all the weight we should be putting on the bars, ergo none. A light touch. It will allow us to steer like lightning. Do everything possible to remove this weight from the bars.
Ignore that. The aerodynamics were created because removing a couple square inches of frontal surface allows 3 more miles per hour, which otherwise might take a massive 10-15 horsepower. The design is to help reach the highest speeds like 200 mph. Bolt on whatever makes your lifestyle better and do not worry about aerodynamics.
