LS2 Stream Fallout Adult Street Helmets

The BEST Technology.

A built-in, drop-down sunshield on a DOT and ECE approved full-face motorcycle helmet for under $150? The LS2 Stream crushes the competition with its factory-direct pricing. It all starts with a lightweight, aerodynamic shell made using High Pressure Thermoplastic Technology (HPTT). The technical fabric comfort liner includes cheek pads cut from one solid piece of high quality foam using LS2's 3D Laser Technology for a perfect fit and no "hot spots." It's fully removable and washable so you can keep it fresh. (Hand wash and air dry liners.) The Stream has the easiest to use Tool-less Quick Release on the market, and makes swapping shields a breeze. The face shield is scratch resistant, UV resistant, and optically correct. LS2 added a built-in Twin Shield System drop-down sun shield, so you get an amazing helmet at an unbelievable value.

  • Chin curtain

  • Magna-Tech liner - LS2 uses a small magnet to hold the neck roll securely in place while riding
  • Security:
  • To ensure optimal protection the helmet must fit your head to perfection, special attention should be paid to the shell shape design and materials to minimize the effects of a possible impact. It is key to obtain a perfect fit to your head from outside to inside, as well as the shell, the configuration of the EPS liner, which should match closely the human head shape
  • Quick-release strap - The metal buckle attaches to a high-quality safety strap. On the other strap is a ribbed plastic tab. Insert the ribbed plastic tab into the metal buckle. You'll hear a light "clicking" sound. Continue to slide it until you get a comfortable, snug fit. Pull the ribbon on the lever to release. For additional initial adjustment, use the metal slider buckle on the strap with the ribbed plastic tab to take up excess strap
