Built for gravity-focused riding, the Lazer Chase KinetiCore is a full-face mountain bike helmet that delivers downhill-competition-level protection in a lightweight, well-ventilated package. Whether you're hitting the bike park, charging enduro stages or lining up for a DH race, the Chase KC has the credentials and the comfort to back you up.

Highlights

• ASTM F1952 downhill certified: meets CPSC, CE and ASTM DH standards for race-ready confidence.
• KinetiCore integrated protection: controlled crumple zones built directly into the EPS shell absorb the energy of both direct and rotational impacts — no add-on liner required.
• Breakaway visor: designed to separate on impact to reduce rotational forces on the head and neck.
• 11 ventilation channels: KinetiCore channelling directs airflow through the helmet to keep you cool on long climbs and bike park laps alike.
• Double D-ring buckle: proven race-grade closure for a secure, rattle-free fit.
• Neck brace compatible: designed to work with leading neck brace systems for maximum protection.
• Plush, sweat-wicking liner: removable and washable for long-term freshness.

KinetiCore Technology

Most helmets manage rotational impacts with a separate liner system added inside the shell. KinetiCore builds the protection in. Controlled crumple zones are moulded directly into the EPS foam, flexing and deforming on impact to redirect energy away from the brain. The result is effective rotational and direct impact protection with no extra weight or thickness. The Virginia Tech Helmet Lab awarded the Chase KinetiCore a 5-star rating.

Ventilation & Comfort

Eleven vents — larger than most full-face designs — are paired with KinetiCore channelling that actively moves air across the rider's head. The plush inner liner wicks moisture and can be removed for washing, while the overall construction keeps the helmet light enough for all-day wear.

Compatibility & Fit

Size XL fits head circumferences of 60–62 cm. The Chase KC is neck brace compatible and suitable for downhill, enduro and bike park riding. Available in XS, S, M, L and XL. Always measure your head circumference before ordering and replace the helmet after any significant impact.
