The reason they have a plastic faux tank is to tie it in with their brand, yes its completely useless. The more important question I think is why do they think they can charge 30 grand for a bike that is out performed by a bike 2/3rds the price? The Zero SR's top of the line model is 20 gs and has a lot more torque about 50 lbs more then the HD.I saw a noon news item on the EV a while ago. My first thought was why does it have a gas tank... Since you don't need gas, why not make it a really useful shape: easier to hang onto with your knees while cornering? Or rectangular and large enough to fit 12 american shitty beer cans in?
