yep I see the difference. The 2011-2014 bearing was an "upgrade". instead of the assembly rotating on a plastic piece it now has a bearing. Only problem is that the bearing looks like it should be in a powerwheel toy hahaha. Its so cheap did you notice that the instructions say to put it over a clean surface incase the ball bearing fall out? lol and they will and did!! hahaha O well.
