The Lazer Chase KinetiCore is a lightweight full-face mountain bike helmet built for riders who demand downhill-level protection without the bulk. ASTM F1952 downhill certified and packed with KinetiCore integrated impact technology, it suits bike park laps, enduro descents and gravity riding of all kinds.

Highlights

  • KinetiCore protection: Controlled crumple zones moulded directly into the shell manage both direct and rotational impact forces — no added liner inserts needed.
  • ASTM downhill certified: Meets ASTM F1952 DH competition standard, plus AS, CE and CPSC certifications for global compliance.
  • Breakaway visor: Integrated visor is engineered to detach under impact, reducing rotational force transfer to the neck.
  • Double D-ring buckle: Reliable, rattle-free closure keeps the helmet securely in place on technical terrain.
  • 11-vent ventilation system: Generous airflow channels keep your head cool without compromising coverage.
  • Plush inner liner: Moisture-wicking padding delivers all-day comfort on long bike park sessions.
  • Lightweight construction: 990 g (size M) — approximately 10% lighter than comparable downhill-certified full-face helmets.

KinetiCore technology

KinetiCore is Lazer's fully integrated rotational impact protection system — the controlled crumple zones are built directly into the helmet's polycarbonate shell and EPS foam rather than added as a separate component. On impact, these zones compress in a controlled pattern that redirects energy away from the head and reduces rotational forces linked to serious brain injury. The result is a lighter, quieter helmet with no additional parts to squeak, rattle or degrade over time.

Ventilation & comfort

Eleven vents channel air through the shell to keep you cool during climbs and sustained descents. The removable, washable inner liner uses moisture-wicking fabric to manage sweat and maintain a fresh, secure fit across long sessions. The flexible front grid adds face protection from roost and splash without restricting airflow.

Compatibility & fit

Size XL fits head circumferences of 60–62 cm. The Chase KC is sized XS through XL — measure your head circumference and refer to the Lazer size chart before ordering. Always replace a helmet after any significant impact, regardless of visible damage.
