Bell Lithium Plus RSD Obispo MIPS 2026 Adult Street Helmets
A dynamic new shell design, an integrated drop-down sun shield and a multi-density EPS liner for superior energy management are just the beginning of what sets Lithium apart from the rest. Class 1 rated optics with the Clickrelease V2 shield, and an optional Pinlock shield in the box means Lithium punches above its weight. And three separate shells ensure optimum fitment across the size range. These rider-first features make Lithium a must-have for motorcyclists who refuse to compromise.
Lithium MIPS + takes aggressive style to the next level, engineered for performance-driven riders with premium upgrades. Dazzling pearl, metallic, and color-shift graphics turn heads, paired with a matching iridium reflective face shield for a bold, cohesive look. Inside, a removable liner ensures all-day comfort, while the Click Release V2 shield with ratcheting detents and four closable vents offer customizable airflow. Comms-ready, with a micrometric buckle and DOT/ECE 22.06 certifications, Lithium MIPS + blends cutting-edge protection with standout design—built to exceed expectations and dominate the road.
