DescriptionThe whole story

The Just1 J-GPR in the Marco Melandri Replica livery is a full-face racing helmet built around a genuine 3K carbon fibre shell — one of the most demanding materials in the sport — and engineered for riders who refuse to compromise between track performance and road refinement. Every curve of this striking replica graphic is laid over a shell that has been constructed using Just1's proprietary S.D.C. (Sequential Density Construction) system, where multiple materials of differing densities work together to absorb and redirect both linear and rotational impact forces. The result is a helmet that wears the name of a MotoGP champion and backs it up with the engineering to match.

Key Features

  • 3K carbon fibre shell available in 4 shell sizes paired with 4 EPP/EPS liner sizes for a genuinely precise, anatomical fit
  • S.D.C. (Sequential Density Construction) multi-density impact system addresses both linear and rotational crash forces
  • J.1.E.R. emergency cheek-pad removal system allows first responders to extract the helmet safely without risk of secondary injury
  • PROTX2 antimicrobial technology woven into the interior fabric keeps the liner fresh across long riding seasons
  • Comprehensive ventilation circuit with 5 intake and 6 exhaust ports, plus an integrated, ventilated chin guard lined with EPS
  • Anti-fog Pinlock visor included as standard, with a dark tinted visor also in the box — ready for sun or shade
  • Hydration-system ready: the shell is prepared for a CamelBak-style drinking tube

Construction and Materials

Four distinct shell sizes mean the J-GPR is never simply scaled up or down from a single mould. Each size is engineered independently, so the carbon fibre maintains its optimum thickness and structural integrity regardless of whether you wear an XS or an XXL. The gloss finish on the Marco Melandri Replica graphic is applied with the same attention to detail as the underlying safety architecture — this is a display-quality livery on a race-certified shell.

The interior is equally considered. A removable and fully washable liner retains its shape and antimicrobial properties through repeated washing cycles. A new liner-retention net keeps the padding precisely located so comfort does not degrade over time. The double-D-ring retention system is the benchmark fastener choice for track use: simple, secure, and independently verifiable at a glance.

Ventilation and Comfort

Eleven vents in total — five intakes channelling fresh air directly across the crown and forehead, six exhausts drawing heat away from the back of the shell — create a through-flow circuit that keeps concentration sharp on long summer sessions. The integrated rear spoiler contributes aerodynamic stability at speed, while the EPS-lined chin section adds protection where many helmets remain thin. For riders who push hard in warm conditions, the CamelBak preparation allows hydration without removing the helmet.

Fitment and Compatibility

The Just1 J-GPR is a universal full-face helmet suitable for all motorcycles. Select your size using the guide below: measure approximately 1 cm above the ears around the widest point of your head.

  • XS — 53–54 cm
  • S — 55–56 cm
