You guys must have really boring lives if you're worried about the sound of a motorcycle and whether or not it has a modulating headlight. I wish those things could be in my priority list of worries. Right under people using the 10 item express lane and buying a 24 pack of Natty Light.
Not "worried"; just annoyed. I thought this was supposed to be a "sportbike education" thread. Just sharing a couple reasons why some cager might be annoyed at some motor-bicyclist in the rear view...
