HJC RPHA 1 Helmet - SENIN MC-1SF

The HJC RPHA 1 is HJC's flagship full-face helmet, developed with direct input from the brand's MotoGP racing programme. Its shell is constructed from PIM+ (Premium Integrated Matrix Plus), a multi-composite layup combining carbon fibre, glass fibre and aramid fibres to achieve a high strength-to-weight ratio suited to performance riding on road and track.

The interior features a 3D-fitted, moisture-wicking liner with removable and washable cheek pads that include an emergency quick-release system — a feature carried over from HJC's race homologated helmets. ECE 22.06 certified, the RPHA 1 meets the most current European homologation standard and is approved for road use in Australia.

The Senin MC-1SF colourway presents a bold race-inspired graphic on the shell in HJC's semi-flat finish, making it a standout choice for riders who want podium-level engineering with a distinctive look.

Clean the outer shell with a soft cloth dampened with warm water and mild soap; never use petroleum-based solvents, petrol, paint thinners or harsh household cleaners, as these can degrade the shell finish and underlying composite materials.
Clean the visor with warm water and a soft microfibre cloth; avoid abrasive cleaners or paper towels, which can scratch the anti-scratch coating and impair optical clarity.
Fit and remove the Pinlock 120 MaxVision lens gently; clean it only with a soft, damp cloth using minimal pressure — aggressive wiping can cause micro-scratches that reduce the lens's anti-fogging effectiveness.
Remove the interior liner and cheek pads and hand-wash with a mild detergent in cool water; do not machine-wash or tumble-dry; allow to air-dry completely before refitting to prevent odour and mildew.
Store the helmet in its protective bag in a cool, dry location away from direct sunlight, fuel fumes, oils and solvents, which can degrade EPS liner performance over time.
Do not apply adhesive stickers, paint or aftermarket coatings to the shell unless explicitly confirmed safe by HJC — solvents in adhesives and aerosol paints can compromise structural integrity.
Replace the helmet immediately after any significant impact, even if no external damage is visible; EPS liner compression is often internal and not apparent to the eye.
As a general guideline, plan to replace the helmet within five years of the manufacture date regardless of apparent condition, as shell and liner materials degrade over time even with minimal use.
