DescriptionThe whole story

The Just1 J-STR Astro in its striking gloss Red / Blue / Black graphic is a full-face helmet designed for riders who want reliable everyday performance without sacrificing style. Built on the proven J-STR platform and certified to ECE 22.06, it earns its place as a dependable daily companion whether you're commuting across town or stretching out on a weekend road run.

Key Features

  • ABS outer shell produced in 2 shell sizes for a more precise fit across the size range
  • EPS inner shell in 2 densities, optimising impact management for each shell size
  • ECE 22.06 and DOT certified — meets the latest international safety standards
  • J.I.E.R. Emergency Cheek Pads Removal System for rapid, safe helmet removal by first responders
  • Robust double-D ring fastening — the trusted standard for secure retention
  • Protx2 antimicrobial lining treatment keeps the interior fresher for longer, even on back-to-back rides
  • Wide Vision visor with scratch-resistant clear lens and Pinlock 70 preparation for anti-fog use in cold or wet conditions

Comfort You Can Feel on Every Ride

Day-to-day wearability is where the J-STR Astro genuinely delivers. The fully removable and washable interior can be refreshed whenever needed, while the comfortable cheek pads hold your head securely without creating pressure points over long distances. An efficient ventilation system channels airflow through the shell, keeping temperatures manageable during urban stops and open-road stints alike. The Protx2 antimicrobial treatment works quietly in the background to resist odour build-up, so the helmet stays pleasant ride after ride.

Visor and Visibility

The Wide Vision visor provides a broad, unobstructed field of view that makes filtering through traffic and reading the road ahead noticeably easier. The clear lens is scratch-resistant and prepared for an optional Pinlock 70 insert, which virtually eliminates fogging in damp or cold weather. A nose cover is included in the box to reduce interior airflow and further manage misting at lower speeds.

Design and Finish

The Astro graphic wraps the gloss shell in a confident combination of red, blue and black — a colour scheme that reads cleanly at speed and stands out in a sea of plain lids. It suits naked bike and sport bike riders looking for a head-turning finish that does not demand track-day pricing.

Fitment and Compatibility

The Just1 J-STR Astro is a universal full-face helmet suitable for adult riders across all motorcycle types. Use the size guide below to select the correct fit before ordering.

“Two shell sizes and two EPS sizes at 1,520 g, with a double-D ring, emergency cheek-pad release and a fully vented chin bar — a proper specification for the money. Be aware of what is behind the score: nobody has measured this helmet independently, so those areas are left out of the total rather than guessed.”
