Built for riders who send it hard. The Lazer Chase KinetiCore is a lightweight full-face mountain bike helmet engineered for downhill, enduro, and bike park riding. With multi-standard certification (AS, CE, CPSC, ASTM DH) and Lazer's KinetiCore integrated impact protection, it delivers serious protection without the bulk of traditional full-face designs.

Highlights

• KinetiCore integrated protection: Controlled crumple zones built directly into the shell manage both direct and rotational impact forces — no separate MIPS insert needed.
• ASTM DH certified: Meets ASTM F1952 downhill mountain bike standard, plus AS, CE, and CPSC certifications for broad compliance.
• Neck brace compatible: Engineered to work with protective neck braces for riders who want maximum protection on technical terrain.
• Breakaway visor: Designed to separate cleanly on impact, reducing the risk of excess shell rotation.
• 11 ventilation channels: Strategically placed vents keep airflow moving through the helmet during sustained efforts and warm-weather laps.
• Secure double D-ring closure: Reliable, time-tested retention system that stays put under impact loads.
• Plush removable liner: Sweat-wicking padding can be removed for washing, keeping the helmet fresh across long seasons.

KinetiCore technology

KinetiCore replaces the traditional add-on rotational impact liner with controlled crumple zones integrated directly into the helmet's construction. When impact occurs, these zones deform in a controlled way to absorb and redirect both linear and rotational forces — resulting in a lighter, cleaner helmet that doesn't compromise on protection. It's the same technology Lazer deploys across their road and gravel range, now brought to full-face MTB.

Construction

The Chase KC uses a polycarbonate outer shell over an EPS foam liner, with fiberglass and carbon fibre reinforcement where it counts. The result is a helmet that weighs just 990g in size M — notably lighter than many downhill-certified full-face alternatives — while maintaining the rigidity needed for high-speed impacts.

Compatibility & fit

Size M fits head circumferences of approximately 56–58 cm. Available in XS (52–54 cm), S (54–56 cm), M (56–58 cm), L (58–60 cm), and XL (60–62 cm). Measure your head circumference at its widest point and refer to the Lazer size chart before ordering. Compatible with standard neck braces. Always replace your helmet after any significant impact.
