HJC i90 Helmet - LARK MC-3H

The HJC i90 LARK MC-3H is a modular flip-up helmet that combines the ventilation and convenience of an open-face design with the protection of a full-face shell. It suits commuters and touring riders who regularly need to communicate at stops without removing their helmet.

The LARK graphic is finished in HJC's MC-3H colourway on an advanced polycarbonate composite shell. A drop-down inner sun visor and Pinlock-ready face shield mean riders can adapt quickly to changing light conditions without carrying additional equipment.

The fully removable and washable interior liner and quick-release cheek pads make the i90 easy to maintain and straightforward to fit across different head shapes.

• Modular flip-up chin bar — open-face convenience with full-face coverage
• Integrated drop-down inner sun visor for fast light adaptation
• Pinlock-ready clear face shield reduces fogging in cold or humid conditions
• Advanced polycarbonate composite outer shell
• Multi-density EPS impact liner
• Fully removable and washable comfort liner
• Quick-release cheek pads for secure fit adjustment
• LARK graphic presented in MC-3H colourway

Clean the outer shell with warm water and a mild soap solution; avoid petroleum-based solvents, thinners, or abrasive cloths that can damage the polycarbonate shell and graphic finish.
Clean the face shield with a dedicated visor cleaner or mild soapy water applied with a soft cloth; never wipe a dry visor as this scratches the surface and impairs vision.
Fit and align the Pinlock insert according to the insert manufacturer's instructions, ensuring the seal is fully seated around the inner perimeter of the shield to prevent fogging.
Remove the comfort liner and cheek pads and hand-wash in cool water with a mild detergent; rinse thoroughly and allow to air-dry completely before refitting — do not tumble-dry.
Raise and lower the flip-up chin bar deliberately and check the locking mechanism is fully latched before every ride; never ride with the chin bar unlocked or partially engaged.
Replace the helmet immediately after any impact, even when no visible damage is present — EPS liner compression is not reversible and the helmet will not provide equivalent protection in a subsequent impact.
Inspect the retention strap, buckle, and D-rings regularly for wear, fraying, or corrosion; replace components or the helmet if the retention system is compromised.
Store in a cool, dry place away from direct sunlight, fuel vapour, and cleaning chemicals, all of which degrade polycarbonate and EPS materials over time — use the supplied bag or a dedicated helmet bag when not in use.
