I was looking at the vid for the Yamaha F3 and it shows this new bike riding with a single headlight illuminated.
I understand this on a dual sport where you may need to turn off one headlight to gain more power to drive heated gear, but why on a Sportbike?
When i see this on the road i always think it looks odd, like the bike blew a bulb.
Is there another reason? Is it required for racing or something?
