The Lazer Chase KinetiCore is a gravity-ready full face helmet built for riders who want certified downhill protection without unnecessary bulk. Lightweight composite construction, integrated rotational impact technology, and a chin bar face grid make it equally at home on bike park laps or enduro descents.

Highlights

  • KinetiCore rotational protection: Integrated controlled crumple zones manage the forces of both direct and rotational impacts without added bulk or a separate liner system.
  • ASTM DH certified: Meets the ASTM 1952 downhill standard, plus CE (EN 1078) and CPSC and AS certifications — cleared for gravity disciplines.
  • Virginia Tech 5-star rated: Independent testing places the Chase KinetiCore among the best available full face helmets for impact protection.
  • Breakaway visor: Designed to separate cleanly during impact to reduce rotational load on the neck and head.
  • 11 ventilation channels: Keeps airflow moving on climbs and transitions without compromising the full face structure.
  • Neck brace compatible: Works alongside leading neck braces for riders who want a full protection setup.

KinetiCore technology

Unlike helmet systems that add a separate rotational liner, KinetiCore builds the protection directly into the EPS foam shell using precisely engineered crumple zones. The result is a helmet that is lighter and cooler than comparable add-on systems while still absorbing the forces of both linear and rotational impacts.

Construction

The Chase uses a composite shell combining EPS foam, polycarbonate, fibreglass, carbon fibre, and nylon for a strong, lightweight structure. The plush, sweat-wicking inner liner can be removed for washing. Closure is via a secure double D-ring buckle — the trusted standard for full face MTB helmets.

Compatibility & Fit

This listing is size XS, fitting a head circumference of 52–54 cm (20.5–21.25 in). Measure your head circumference at the widest point above the ears before ordering, and check the Lazer Chase size chart. Always replace your helmet after any significant impact, regardless of visible damage.
