Built for gravity riding without compromise. The Lazer Chase KinetiCore is a lightweight full-face mountain bike helmet that combines downhill-certified protection with all-day trail comfort — making it equally at home on bike park laps, enduro stages and shuttle days.

Highlights

• KinetiCore rotational impact protection: Controlled crumple zones built directly into the EPS foam absorb the forces of both direct and rotational impacts, reducing rotational energy transferred to the brain without added bulk or a separate MIPS liner.
• ASTM DH certified: Meets the ASTM F1952 downhill mountain bike standard, with additional CPSC, CE (EN 1078) and AS compliance for full international and Australian approval.
• Breakaway visor: Engineered to detach cleanly on impact, reducing neck load and rotational forces during a crash.
• Double D-ring closure: Proven, reliable retention system used by racers for a secure, rattle-free fit.
• 11 vents: Generous ventilation channels keep airflow moving through the helmet so you stay cool on climbs and warm-up laps.
• Flexible front grid: Defects trail spray and debris while remaining comfortable against the face.
• Plush inner liner: Sweat-wicking padding delivers a snug, comfortable feel across long days in the bike park.
• Neck brace compatible: Designed to work with standard neck brace systems for riders who run added protection.

KinetiCore technology

KinetiCore is Lazer's integrated rotational impact protection — the controlled crumple zones are moulded directly into the helmet shell, so there are no separate liners to replace or maintain. Under impact, the zones deform in a controlled way to redirect and absorb rotational energy before it reaches your head. The result is a lighter, cooler helmet that still delivers class-leading protection.

Construction

The Chase KinetiCore shell combines EPS foam, polycarbonate, fibreglass and nylon to balance stiffness, energy absorption and weight. At approximately 990g (size M), it punches well below its weight for a full-face DH-certified helmet. The Matt Dusty Blue colourway is a muted, trail-ready finish that resists showing dirt and scuffs.

Compatibility & fit

This listing is size S, suitable for head circumferences of 54–56 cm (21.25–22 in). Available in five sizes from XS to XL. Measure your head circumference at the widest point above your ears and refer to Lazer's size guide before ordering. Always replace a helmet after any significant impact, even if no damage is visible.
