I'm looking into picking up a Kawasaki Versys 650 and I was curious if there is anything that might have changed much over the years I should be aware of or that would make one year more appealing than another?

I was really wanting to get a used one. I know looks aren't everything but I love the looks of the 2008/2009 but then hate the looks of the 2010-2014. Then comes the 2015 which looks simply amazing.

So in terms of power, comfort, anything else that would be worth looking in to has much changed? If it isn't obvious yet I don't know a whole lot about cycles.

Also what part of 2016 would a 2016 Versys come out that I could find discounts on the 2015 models?

Thanks for any help!
