I've experienced some grabbiness with the front brake on my 2007 America. Like coming up to a stop sign where you think the intersection is clear, but then realize its not, you end up grabbing some brake and sometimes with the front wheel turned slighty, you end up getting a litte more brake than you expect. Had this happen a few times to the point where I almost thought I was gonna drop the bike. In normal use its fine, just in those low speed situations it can be a little "grabby".
