1. Proper fit

To ensure maximum safety, the helmet should fit perfectly and feel comfortable when you wear it. To determine the correct helmet size, the first thing you need to do is to measure your head with a tape measure.

    • Place the tape measure around the crown of your head a couple of centimeters above the eyebrows and ears. ( you can look at the size chart table)
    • Based on the helmet size that you have just determined, now you must try the helmet on to make sure that it fits properly and feels comfortable.
    • The last step is to fasten the chinstrap as tightly as possible but without hurting and with your head bent forward, try to remove the helmet by pulling it from the back to the front.
    • If the helmet comes off easily, it means that it is not the right size for you. Try a smaller size.
  1. Helmet shell

To protect and take care the helmet shell, use cotton swabs to clean out vents and joints. Use soft, scratch-free microfiber towels to clean your helmet. Keep the helmet away from objects that can damage the helmet.

    • Do not use any petroleum distillate or solvent-based cleaner on your helmet and also, do not use glass cleaner or any ammonia-based cleaner
    • Do not apply paint, substances and any other solvent to the helmet. Helmet can be seriously damaged.
    • Don’t make any modifications on helmet parts and structure.
    • If the helmet has experienced a severe impact should be replaced immediately

  1. Pinlock®

Your Pinlock® lens is made from a moisture absorbing plastic. The Pinlock® lens fits exactly into the dedicated recess in the helmet visor and provides you with a maximized free field of view.

The silicon seal on the Pinlock® lens creates an insulating air pocket between the Pinlock® lens and the helmet visor.

The pins, Between which the Pinlock® lens is to be fitted, are eccentric, which means that the axis of the pin is not precisely in the center.

This enables you to increase or decrease the tension on the Pinlock® lens by turning the pins, allowing the silicone seal to have a perfect fit.

Please notice! The Pinlock® lens is less resistant to scratching than the helmet visor!

How to install Pinlock® lens :

    • Remove the helmet visor from the helmet as shown in manual Instructions.
    • Flex the helmet visor and place the Pinlock® lens between the two pins provided in the helmet visor and then allow the helmet visor to reacquire its curved shape. The silicon seal on the Pinlock® lens must make full contact with the helmet visor in order to avoid any condensation forming between the helmet visor and the Pinlock® lens.
    • Remove the protective flm from the Pinlock® lens.
    • Fit the helmet visor back on the helmet.

How to remove Pinlock® lens :

    • Remove the helmet visor or visor from the helmet as shown in manual instructions.
    • Flex the helmet visor carefully until there is no more tension on the Pinlock® lens.
    • Carefully remove the Pinlock® lens from its position.

How to clean Pinlock® lens :

    • Remove the Pinlock® lens as shown in the paragraph “removing”.
    • Only clean the Pinlock® lens and the helmet visor using mild liquid soap, lukewarm water and a soft moist cloth.
    • Allow the Pinlock® lens and the helmet visor to dry naturally before reassembling them.
    • Do not use abrasive cleaning products or liquids that contain ammonia or alcohol.
