The blue bar looks exceedingly narrow to me ... commuter-width road-cycling narrow. Could just be the angle of the photo.

Bars on my Rize 4 are 670 mm and don't feel wide at all. I know I tried a few bars ion my last MTB, and eventually resorted to the hacksaw to get the width I wanted--which I think was wider than I use now. But that bike rode and balanced completely differently.
