They make these bikes have the "cyclops" look (one low beam) for a very good reason. Safety.
Let's say you're coming to an intersection. There's a car coming waiting to turn into your lane of traffic. If you have both headlights running the front of your bike will appear to be a car at a further distance away than you actually are. Said car turns in front of you thinking you're actually a car much further away. Bam. You hit said car.
The perception from the drivers point of view is that "he looked like a car and I thought it was further away than that."
