The HJC RPHA 70 is a premium full-face helmet designed for sport-touring and road riding, built around HJC's lightweight PIM+ (Premium Integrated Matrix Plus) composite shell. It sits in HJC's upper-tier RPHA family, balancing aerodynamic performance with everyday comfort.

This listing features the KOSIS graphic in the MC-1SF colourway — a bold, race-inspired finish suited to riders who want a distinctive look without sacrificing function. The interior is fully removable and washable, and the visor system is designed for quick, tool-free replacement.

An ideal choice for commuters and touring riders seeking a well-appointed lid with a premium graphic finish at a competitive price point.

  • Remove the inner liner and cheek pads before washing; hand-wash in mild soap and warm water, then air-dry completely before reassembling.
  • Wipe the outer shell with a damp microfibre cloth and mild soap; avoid solvent-based cleaners, petrol, or abrasive pads that can degrade the shell and graphics.
  • Clean the visor with a soft damp cloth; never dry-wipe a dusty visor as it will scratch the lens coating.
  • Deploy and retract the inner sun visor using the side lever; keep the mechanism clear of debris to prevent sticking.
  • Replace the visor using the RapidFire Plus mechanism — no tools required; inspect the visor seal periodically for wear.
  • Install a Pinlock insert into the visor if riding in cold or humid conditions to reduce fogging.
  • Check helmet retention strap and buckle for fraying or corrosion before each ride.
  • Store the helmet in its bag or a cool, dry location away from direct sunlight, fuel vapours, and solvents.
  • Replace the helmet after any significant impact, even if no visible damage is present — internal EPS damage may not be obvious.
  • As a general guideline, consider replacing the helmet after 5 years of regular use or as recommended by HJC, due to gradual degradation of materials.
