Are you sure? It looks like it bolts on through existing vents. I would think there would be a better market for an add-on since so many people bought the Super. If I'm going to spend $300 for another helmet then I'll buy the Urge and have more options!
It is hard to see how the side latches attach to the helmet, but I think there has to be something to latch onto that is an integral part of the helmet and vents would not be skookum enough. The rear attachment does look like it plugs into existing vents but not the sides. I think that there is a little lip for a catch at the front side of the helmet edge just in front of the temples.
Debate? Bikes are made for riding not pushing.
