HJC I71 Helmet - SIMO MC-21SF

The HJC i71 is a full-face road helmet built for everyday riders who want ECE 22.06-rated protection without unnecessary complexity. Its polycarbonate shell is paired with a multi-density EPS liner and a full ventilation system, making it a practical choice for commuting and weekend riding alike.

The SIMO graphic in MC-21SF (Sun Fluo) brings a fluorescent hi-visibility finish that helps riders stand out in traffic. An integrated drop-down sun visor and included Pinlock 30 anti-fog insert mean the i71 is ready for the variable light and weather conditions common across Australian roads.

Clean the outer shell with mild soap and warm water on a soft cloth; avoid petroleum-based products, solvents or abrasive cleaners that can degrade polycarbonate.
Clean the visor with a dedicated visor cleaner or mild soap and water; never use dry cloths or paper towels, which can scratch the anti-scratch coating.
Remove the interior liner and cheek pads and hand-wash in cool water with mild detergent; allow to air dry completely before reinserting.
To deploy the integrated sun visor, operate the visor lever smoothly; ensure the sun visor is fully retracted before removing or fitting the helmet to avoid damaging the mechanism.
If fogging occurs, confirm the Pinlock 30 insert is correctly seated on the visor's Pinlock pins and that the silicone seal makes full contact around the insert perimeter.
Store the helmet in a cool, dry location away from direct sunlight, fuel vapours and chemical fumes, all of which degrade shell and liner materials over time.
Do not paint, apply stickers with solvent-based adhesives, or use aerosol sprays directly on the shell, as these can weaken the polycarbonate structure.
Replace the helmet after any significant impact — even without visible damage, the EPS liner may be internally compromised and will no longer absorb energy as designed.
As a general guideline, consider replacing the helmet after five years of regular use, or sooner if the shell, liner, retention strap or buckle show signs of deterioration.
