Built for gravity riders who don't compromise on protection. The Lazer Chase KinetiCore is a lightweight full-face mountain bike helmet offering ASTM downhill certification and integrated KinetiCore rotational impact technology — so you can charge descents, hit the bike park, and tackle enduro stages with confidence.

Highlights

• KinetiCore rotational impact protection: Controlled crumple zones built directly into the EPS foam absorb both direct and rotational impact forces without added weight or bulk.
• ASTM 1952 DH certified: Approved for international downhill racing and meets CE EN 1078, CPSC, and AS standards.
• Virginia Tech 5-star rated: Independently tested and awarded the highest available protection rating.
• Breakaway visor: Engineered to detach upon impact, reducing rotational forces transferred to your neck.
• Neck brace compatible: Designed to work with standard neck braces for riders who want maximum protection.
• 11 ventilation ports: Keeps airflow moving on long climbs and bike park laps without sacrificing coverage.
• Double D-ring closure: Reliable, race-proven buckle system for a secure, consistent fit every ride.

KinetiCore technology

KinetiCore is Lazer's integrated rotational impact protection system — the first of its kind built directly into the helmet's EPS foam rather than added as a separate liner. Structured crumple zones flex and compress on impact, redirecting both direct and rotational energy away from your head. The result is a helmet that protects more, weighs less, and breathes better than traditional dual-layer designs.

Construction & comfort

The Chase KinetiCore is constructed from a composite shell combining polycarbonate, fibreglass, and carbon fibre over an EPS foam core. A plush, sweat-wicking inner liner keeps you comfortable across long days in the saddle, while the flexible front grid shields your face from trail debris and splashes. Goggle retention channels keep your goggles securely in place on rough terrain.

Compatibility & fit

Size M fits a head circumference of 56–58cm. If your measurement falls between sizes, Lazer recommends selecting the smaller size for a snug protective fit. The Chase uses a single outer shell across sizes, with varying padding thickness for precise fitment. Replace your helmet after any significant impact — even if no visible damage is present.
