ENGADGET - Putting a clear pane in the back of a motorcycle helmet, viewable via a front-mounted mirror, might seem like an obvious idea in, er, hindsight, but it took helmet manufacturer Reevu to make it a reality. The company’s MSX1, which has been the worst-kept secret in biker circles for several years, has finally made its official debut, at the EICMA show in Milan. The helmet relies on a distinctive raised crown, which provides a clear line of sight from front to back, enabling the mirror — made of unbreakable reflective polycarbonate — to capture the view from the rear. The helmet is expetcted to be available worldwide at about $399 early next year.

Hot. Not as hot as a heads up display on the visor with current time, map, nearest gas stations marked where I will need them based on my current MPG, a bluetooth headset for my cell phone, and a display of everything behind me, but still hot.
