Lazer's new A-Line KinetiCore is a carbon, dual-certified full-face that chases near-enduro weight with full downhill protection — at a premium US$499.99 (~R8 200).
What Lazer just dropped
Lazer has pulled the wraps off the A-Line KinetiCore, a carbon-shelled full-face that sits at the very top of the Belgian brand's gravity range — above the existing Cage and Chase models. It pairs Lazer's in-house KinetiCore rotational system with a new dual-density DualCore liner, and arrives dual-certified for both downhill racing and higher-speed e-bike use.
It launched at US$499.99 (~R8 200) / €499.99 (~R9 400) / CA$699.99 (~R11 500) in five sizes and three carbon colourways, with first units shipping from October 2025. Full details first appeared via Bikerumor.

Inside the shell: KinetiCore meets DualCore
KinetiCore is Lazer's MIPS alternative: blocks of EPS foam engineered to crumple and shear on impact, managing both direct and angled (rotational) forces without a separate slip-liner. For the A-Line, Lazer layers that with new DualCore — a soft, low-density foam next to your head to absorb rotational energy, and a harder, high-density layer further out to blunt direct hits.
Gravity-specific touches round it out: emergency-release cheek pads so first responders can lift the helmet without twisting your neck, a soft lower trim shaped to spare your collarbones, a fixed visor with an under-visor camera mount sited to avoid snag hazards, a rear goggle gripper, and a double D-ring chin strap.
How light is it, really?
Here's the honest version of the headline number. Lazer's US site and most first-look coverage quote 840g for a size medium, while the brand's global spec sheet lists an even lighter 790g. On the scale, Vital MTB recorded 895g for their sample.
That's still light for a carbon DH lid — a Troy Lee D4 Carbon is a claimed 1,000g — but it's no record-breaker. The DH-certified Specialized Gambit weighs a claimed 640g (and as little as 602g in a small), so 'one of the lightest in its class' depends a lot on which class you mean.

What the reviewers say
Three early takes
Independent verdicts from across the cycling press — follow each link for the full review.
Useful, not gimmicky
“The fit is comfortable, the weight is low, the visibility is excellent and several of the included features feel genuinely useful rather than marketing hype.”

“The A-Line KinetiCore is in a league of its own if it lives up to its promises.”
Read the full reviewSleek first impression
“...a fairly sleek, low-profile shape and streamlined appearance.”
Read the full reviewThe honest balance sheet
- Dual-homologated: ASTM F1952 downhill plus the higher-speed NTA 8776 e-bike standard
- DualCore dual-density EPS targets both rotational and direct impacts — no separate MIPS liner required
- Carbon shell holds the claim to 840g, lighter than traditional DH lids like the 1,000g D4 Carbon
- Smart gravity details: emergency-release cheek pads (two sizes), under-visor anti-snag camera mount, rear goggle gripper, collarbone-friendly trim
- Box includes a spare visor and premium bag; 50% crash-replacement plus warranty extension on registration
- Reviewers praise a snug, rattle-free fit and excellent forward visibility
- Measured 895g on Vital MTB's scale — over the 840g claim and far heavier than the 640g Specialized Gambit
- Ventilation is modest (7 shell vents); this is a protection-first lid, not the airiest park option
- Premium money at US$499.99 (~R8 200), with no MIPS badge some buyers specifically look for
- D-ring closure is fiddly in gloves; one tester would prefer a magnetic buckle
- Even Lazer's own spec sheets disagree on weight (790g global vs 840g US)
A genuinely light, properly certified carbon full-face with clever gravity details — held back only by modest venting, a premium price and a real-world weight above the claim. Compiled from published reviews; not independently tested by BikeBuy.

Lazer A-Line KinetiCore: your questions
Is it legal for downhill racing? +
Yes. The A-Line is certified to ASTM F1952, the downhill standard that also tests the chin bar, and it additionally meets the Dutch NTA 8776 e-bike standard for higher-speed impacts (plus baseline CPSC and EN 1078).
How much does it actually weigh? +
Lazer's US site and most coverage claim 840g in size M, while its global spec sheet lists 790g. Vital MTB weighed an actual sample at 895g — light for a carbon DH helmet, but not a record.
Does it use MIPS? +
No. Lazer fits its own KinetiCore crumple-zone EPS plus the new dual-density DualCore liner to manage rotational and direct impacts, rather than a MIPS slip-plane.
What does it cost? +
US$499.99 (~R8 200) / €499.99 (~R9 400) / CA$699.99 (~R11 500) at launch. South African retail prices, where we list them, appear in the price tracker below.
Is it only for downhill, or enduro too? +
It is light enough that BIKE magazine rates it for enduro and alpine freeride as well as DH, though ventilation is modest, so it leans toward shuttle and park use over long pedally climbs.

The A-Line KinetiCore is Lazer's most convincing full-face yet: a carbon, dual-certified gravity lid with genuinely useful details and a fit reviewers rate highly. Just go in clear-eyed — it's a claimed 840g that weighed 895g in independent hands, the venting is deliberately modest, and at US$499.99 (~R8 200) the lighter, cheaper Specialized Gambit makes it work for every gram and dollar. If you want carbon DH protection that still feels light on a long park day, it belongs on your shortlist; if outright low weight or airflow is the priority, shop the comparison first.
