Designed for riders who demand downhill-level protection without sacrificing ventilation or weight, the Lazer Chase KinetiCore is a full-face mountain bike helmet built for bike park laps, enduro descents, and gravity riding. With a Virginia Tech five-star safety rating and multi-standard certification, the Chase gives you the confidence to push harder.

Highlights

• KinetiCore rotational impact protection: Integrated controlled crumple zones absorb both direct and rotational forces without a separate liner system, keeping the helmet lightweight and efficient.
• ASTM DH certified: Engineered and certified to ASTM F1952 downhill mountain bike standards — plus CPSC and EN 1078 — for trusted protection on the most demanding terrain.
• 11 ventilation channels: Generous airflow keeps you cool on climbs and bike park laps without compromising structural integrity.
• Breakaway visor: Designed to separate cleanly on impact, reducing rotational forces transferred to the rider's neck and spine.
• Double D-ring closure: Time-proven buckle system keeps the helmet securely in place through rough terrain and crashes.
• Neck brace compatible: Designed to work with popular neck braces for riders who want an additional layer of protection.
• Virginia Tech five-star rated: Independently tested and awarded the highest safety rating by the Virginia Tech Helmet Lab.

KinetiCore Technology

Unlike bolted-on rotational protection systems, Lazer's KinetiCore is built directly into the helmet shell using controlled crumple zones. These zones deform in a managed way during both linear and rotational impacts, dispersing energy more effectively across the helmet. The result is a plastic-free, lighter-weight rotational protection system that doesn't rely on a secondary liner — and doesn't add bulk or heat.

Construction

The Chase KinetiCore shell combines EPS foam, polycarbonate, fibreglass, carbon fibre, and nylon in a construction tuned for the demands of full-face downhill and enduro riding. The plush, sweat-wicking inner liner is removable for washing and long-term freshness. Weighing approximately 990 g (size medium), it sits at the lighter end of the full-face category.

Compatibility & Fit

This listing is size Small, fitting head circumferences of 54–56 cm. The Chase is available in sizes XS through XL.

Always replace a helmet after any significant impact, regardless of visible damage.
