Unfortunately yes, the bike does shimmy if I ride no hands above 25 mph, but not with at least one hand on the bars. This is not a defect, per se, and it's debatable whether a different headset can make a difference. It's simply a matter of trail, load, tire size and tire pressure. Low trail and fat tires both conspire against a bike to promote shimmy.
I have my own thoughts on headsets and how they may prevent shimmy. And it's not what most people think.
