HJC i90 Helmet - LARK MC-1SF

The HJC i90 is a full-featured modular helmet designed for touring and everyday road riding. Its flip-up chin bar mechanism allows easy visor swaps and communication with passengers, while the integrated drop-down sun lens means you can adapt to changing light conditions without stopping.

Built around an advanced polycarbonate shell, the i90 combines a comfortable interior with HJC's ACS channelling ventilation system. The LARK MC-1SF graphic is applied in HJC's semi-flat red finish — a bold look that sits between gloss and full matte.

Suitable for riders who want modular convenience without sacrificing everyday wearability, the i90 is a practical choice for commuting, weekend rides, and longer touring stints.

Clean the outer shell with mild soap and warm water on a soft cloth; avoid solvents, petrol, or abrasive cleaners that can damage the finish and shell integrity.
Clean the visor with the same mild soap solution; never use paper towel or dry cloth, as these scratch the lens.
Remove the cheek pads and interior liner before washing — hand wash in cold water with gentle detergent, reshape, and air-dry flat away from direct heat.
Do not machine wash any helmet component.
Replace the helmet immediately after any significant impact, even if external damage is not visible — EPS foam is a single-use energy absorber.
As a general guideline, replace the helmet every five years from the date of manufacture regardless of apparent condition, as UV exposure, sweat, and general aging degrade materials.
Store the helmet in its bag (if supplied) or a breathable cover in a cool, dry location away from direct sunlight, fuel vapours, and extreme heat (e.g. not in a car boot in summer).
Inspect the chin strap ratchet buckle and flip-up chin bar locking mechanism regularly for smooth, secure operation; do not ride if either feels loose or fails to lock positively.
Lubricate the visor pivot mechanism sparingly with a silicone-based lubricant if it becomes stiff; avoid petroleum-based products.
Ensure the Pinlock insert (if fitted) is seated correctly and the two pins are engaged before riding in cold or wet conditions.
