Built for gravity riders who don't compromise on protection. The Lazer Chase KinetiCore is a full-face mountain bike helmet engineered for downhill and bike-park riding, delivering ASTM DH-certified protection with KinetiCore integrated rotational impact technology — all in a helmet that's surprisingly light and comfortable enough for full-day sessions.

Highlights

• ASTM F1952 downhill certified: meets the highest DH standard, covering enduro and bike-park riding as well as competition.
• KinetiCore integrated protection: controlled crumple zones built directly into the shell manage both direct and rotational impact forces without adding bulk or a separate liner system.
• Virginia Tech "Best Available" rating: independently tested and awarded the top protection rating by Virginia Tech's helmet safety programme.
• Breakaway visor: designed to release cleanly on impact, reducing the forces transmitted to your head and neck.
• 11 ventilation ports: generous airflow to keep you cool on climbs and bike-park laps.
• Neck brace compatible: works with standard neck braces for riders who want maximum protection.
• Double D-ring closure: secure, reliable, and widely accepted across all DH-standard certifications.
• Plush sweat-wicking liner: removable and washable for long-term freshness.

KinetiCore Technology

KinetiCore is Lazer's fully integrated rotational impact protection system — built into the helmet itself rather than added as a separate MIPS liner. Controlled crumple zones within the shell flex and absorb energy during an impact, managing both direct forces and the rotational forces that contribute to brain injury risk. The result is class-leading protection in a cleaner, lighter package.

Construction

The Chase KinetiCore uses a polycarbonate outer shell with EPS foam liner construction. A flexible grid covers the front mouth opening to reduce mud and splash ingress on wet days. The removable liner is machine washable, and the double D-ring chin strap closure is secure and simple to adjust even with gloves on.

Fit & Sizing

This listing is for size L, fitting a head circumference of 58–60cm. The Chase is available in five sizes (XS through XL) — measure your head circumference and refer to the Lazer size guide to select the correct size. Always replace a helmet after any significant impact, even if no damage is visible.
