Product Information

Full details

The Just1 J40 Motocross Helmet is designed for adult motocross riders seeking high-level impact protection and consistent comfort during intense track sessions. Its primary benefit is the combination of ECE 22/06 safety certification with advanced antimicrobial interior technology for improved hygiene and a secure, stable fit. However, users should note that as a dedicated motocross helmet, it features a fixed peak design and specialized ventilation that may not be suitable for casual street or all-weather touring applications.

FAQs

What safety standard does this helmet meet?

How do I remove the cheek pads in an emergency?

The J40 features a specific red-tabbed emergency system; pull these tabs to release the pads for safe helmet removal.

Can I wash the interior lining?

Yes, the interior is removable and should be washed by hand with mild detergent.

Does this helmet come with goggles?

No, the helmet does not include goggles; they must be purchased separately.

Is the visor adjustable?

The J40 features an innovative peak/visor design; check the mounting screws to adjust the height to your preference.

What material is the shell made of?

The shell is constructed from high-strength ABS plastic.

Troubleshooting

Helmet feels loose over time

Check the interior lining for signs of wear and ensure it is properly snapped into place; replace pads if necessary.

Interior smells after heavy riding

Remove the interior liners and wash them with a gentle soap, ensuring they are completely air-dried before reinstallation.

Difficulty putting on the helmet

Ensure the chin straps are pulled outwards while pulling the helmet down to prevent friction with the cheek pads.

Pros and Cons

Pros

  • Meets current ECE 22/06 safety standards
  • Effective odor management with Protx2 technology
  • Includes emergency cheek pad release system
  • Robust high-strength ABS shell construction
  • Excellent ventilation for high-intensity riding

Cons

  • Not intended for non-motocross street use
  • May feel heavier than premium carbon-fiber alternatives
  • Fixed peak requires specific clearance for some goggles

Setup, Compatibility & Care

To ensure your J40 stays in optimal condition, always inspect the shell for hairline cracks after a heavy impact. The lining is removable for washing; use a mild detergent and air dry to maintain the integrity of the antimicrobial treatment. When setting up your gear, ensure the Double D-ring strap is tightened snugly against your chin without restricting circulation. The helmet is compatible with most standard motocross goggles, though you should verify your specific goggle frame size fits comfortably within the eye port before your first ride.
