The Strobe II modular motorcycle helmet continues the tradition of LS2 offering high performance along with high value. The Kinetic Polymer Alloy (KPA) shell offers state-of-the-art energy managing flexibility. The Strobe II meets or exceeds the ECE 22.06 rotational energy management criteria using LS2’s proprietary Advanced Rotational Energy Management (AREM) technology. ECE homologated as both an open face and full-face (ECE P/J rated), this helmet offers amazing flexibility and is able to be used with the chin bar down for highway riding, or up when circulating a parking lot, stopped to take a photo, or talking to your riding buddies at a rest stop. A convenient built-in, drop-down sun shield adds to this flexibility and makes it a breeze to get the shield up and out of the way when entering a tunnel or shadowed area. Removeable liner with special flex-crown system is super comfortable and easy to keep fresh. There’s no other helmet at this price-point that can compete with the Strobe II’s performance, comfort and flexibility. Meets or exceeds ECE 22.06 and DOT FMVSS standards. Intermediate oval fit. DOT approved. Meets the FMVSS 218 Standard.
