What model is actually being sold here? Is this the 2011? I have one made in 2010n and hate how the zipper on the bag sticks and there is no chin pad, have read zipper is better now and now has chin pad - but I thought the newest one had a button on the kick stand? This one looks different than mine (mine is a lighter blue) but there is no button on the kick stand. (I don't really want the button but would like the zipper to work better and have a chin pad)
