Senin HJC RPHA 1N Motorcycle Helmet

The Senin Motorcycle Helmet HJC RPHA 1N is a highly anticipated release that caters to MotoGP enthusiasts. Formerly known as the HJC RPHA 01R helmet, this model has now been renamed as the HJC RPHA 1N helmet since its retirement over a year ago. As part of HJC’s 50th anniversary celebration, this helmet showcases the Sponsored Racer design, which you may have seen in top-tier superbike series like MotoGP and Moto3. It has been specifically engineered to offer exceptional stability and optimal airflow, crucial factors for high-performance racing.

The RPHA 1N helmet proudly boasts the FIM (FRHPhe-01) safety rating, a requirement for all MotoGP racing helmets. Notably, the Senin Motorcycle Helmet HJC RPHA 1 is the European version that lacks the DOT rating. Rest assured, the USA version of the helmet retains the FIM (FRHPhe-01) rating and the ECE rating.

The Senin Motorcycle Helmet HJC RPHA 1N design is directly inspired by the MotoGP track, ensuring a genuine racing experience for consumers. It’s essential to note that this helmet is not a diluted adaptation of a MotoGP race helmet but rather an exact replica in terms of shell design and specifications. The HJC RPHA 1N embodies the characteristics required by world-class riders in MotoGP and WorldSBK circuits. Moreover, it holds the FIM homologation safety certification necessary for MotoGP riders. After years of anticipation, the Senin Motorcycle Helmet HJC RPHA 1N is finally available, meeting and surpassing the expectations of riders worldwide.

HJC Helmet Fitting Instructions

HJC Helmet Warning Icon
Never buy a used helmet or borrow someone else’s helmet. Over time the protective foam in helmets will adjust to the contours of a user’s head. A used or borrowed helmet may not offer as much protection as a new helmet.

HJC Warning Icon
Wearing the wrong size helmet can increase your risk of serious injury or death in an accident. A helmet that is too large for your head may be dislodged or knocked off in an accident. To select the right size helmet for your head, follow these instructions:

  1. Measure your head. Wrap a tape measure around your head about one inch (2.5 cm) above your eyebrows.
  2. Use the sizing chart to select the helmet size that corresponds most closely to your head measurement. If your head size falls between two helmet sizes, try on the larger helmet first and then the smaller size. Click here to see the sizing chart.
  3. Try on the helmet by grasping both chin straps to pull the helmet completely onto your head, ensuring that the top of your head is in contact with the top of the helmet interior.
  4. Check for a proper fit. To make sure your helmet is the right size, check that:
    • The helmet inner lining fits snugly around your head.
    • The top pad presses firmly on your head.
    • The cheek pads contact your cheeks.
    • There is no space around your brow under the inner lining.
    • Test this by trying to insert your fingers. If the helmet does not fit snugly, try on a smaller size.
  5. Check your field of vision when trying on a helmet. Some helmets may obstruct or block your vision when looking left, right, up, or down.

    6. Warning Icon
    Always make sure you can see well enough to safely operate your motorcycle.

  6. Test the helmet fit by placing your hands on each side of the helmet. While holding your head as motionless as possible, try rotating your helmet from left to right then up and down. If you can feel the helmet padding sliding on your head, it is too big, try a size smaller. You should feel the helmet move the skin on your head and face as you try to move the helmet.

    7. * The Sy-Max and CL-Max were designed to be used in the closed chin bar position, thus be sure all helmet “fitting” is done while chin bar is in the closed and locked position.

  7. Fasten the retention system (chin strap) as tight as possible under your jaw without causing pain. There must be no slack in the strap, and the strap must be tight up against your jaw. Click to view the helmet retention system.

    8. Illustration of rotating the helmet forward

  8. Test the retention system (chin strap)<>
    Put your hands on the back of the helmet and try to push the helmet off by rotating it forward.
    Put your hands on the front of the helmet above your forehead (or on the chin guard) and try to push the helmet off by rotating backward.

    HJC Warning Icon
    If helmet comes off, try another size or another model or brand.

    Repeat steps 3 through 8 until you find a helmet that fits your head snugly and securely.
