If it was me, I'd take the speedy in a heartbeat. No doubt what-so-ever.
But I just love the look of the blacked out engine and the mag wheels and the single seat compared to the America.
But if you really can't decide then just go with the America because it's cheaper! And other than the blacked out engine and the expense of the wheels, you can make either look like either. The difference in engine isn't really noticeable. One has more hp and one has more torque and neither is really enough to make a noticeable difference.
So if neither speaks to you right away, get the America.
Isn't it great knowing you can't make a bad decision?
