FAQs
How do I know what size AT4.0 CARBON motorcycle helmet to get?
Take a fabric measuring tape, wrap it around your head just above your eyebrows and ears. Pull the tape until comfortably tight. Take the measurement. Our motorcycle helmet fit is intermediate oval.
How tight should the AT4.0 CARBON motorcycle helmet be?
A helmet should feel snug, with even pressure around your crown and a firm cheek bite. Cheek pads bed in over time, so it shouldn't feel loose (or "perfect") straight away. There should be no helmet movement when turning from side to side. A snug fit is essential for safety.
Does carbon fiber perform better?
Carbon fiber delivers a perfect balance of light weight and superior impact absorbing characteristics, making it a great choice for motorcycle helmets.
What is RHEON™?
It's impact tech that hardens on crash impact, preventing injuries from linear and rotational impacts. Standard headliners can't do this. RHEON™ can.
What buckle does the AT4.0 CARBON motorcycle helmet use? Is it safe?
Fidlock. It's magnetic + mechanical. The magnet pulls the tab in. The mechanical lock holds it. To open, pull tab which will open the mechanism. Wind won't open it. Crashes won't open it. It's much quicker to use than a double D-ring and just as safe.
How do I clean the AT4.0 CARBON motorcycle helmet visor without scratching it?
Rinse the visor first, grit is the enemy. Use mild soap and a microfiber towel. Wipe off. For longlasting protection, order one of our Muc-Off Helmet Cleaning Kits.
