What’s in the BoxClear & tinted visor included

The new gold standard. AT4.0 CARBON Gold is forged through the same lengthy eight-stage nano paint and finishing process as our SOLD OUT Chrome helmet from 2025, delivering a liquid metal shine with rich heat and 24 karat presence. Limited to just 200 individually numbered helmets, this helmet is rare, valuable and highly demanded.

Premium feel, daily usability. Every touchpoint is tuned for repeat rides. Easy to live with, confidence-inspiring to wear, and made to stay comfortable when the hours stack up.

Sport model for fast, high-octane rides. AT4.0 Carbon takes the Street attitude and dials it up. Stronger, sharper, and more advanced for riders who live for speed, with a true performance edge when you’re pushing on. Explore AT4.0 Carbon.

The value is in the platform. Clean design now, options later. Add Shockwave Bluetooth audio (sold separately) for music, navigation, calls and rider-to-pillion comms. Switch up the look with visors.

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.

I love this helmet. I would recommend it to anybody. The shockwave system does have a couple bugs, though nothing too major.
WardukeJune 1 2026
Disagree helmet are our helmets if you get the proper size fit so well Pfizer is easy to change. The vents were great and snug around your head so when it’s chilly out, you stay good winds not whistling up under your helmet. They’re just great helmets plus they’re also the ECE instead of just the DOT.
Sammy KitchensJune 1 2026
It's a beautiful helmet. I love the graphics and everything. But the not very wind resistance. Its very noisy when going over sixty mph

Helmet is beautiful
Mrs GMay 22 2026
Great quality and my husband loves it! I ordered that Catwoman to match but I really want you guys to come out with a Harley Quinn remake
PhilMay 20 2026
Design turns heads and quality of finish on the helmets feels and looks great. Helmet is tight to get on but once on fits well apart from there’s a noticeable tightness on my cheeks which makes me adjust the helmet more than I expected. Quality of liner feels fine and hoping this issue fades the more I wear it. Had it on for 5 hours and no real issues. Visor was swapped for tinted and really happy with how it closes and the level of tint. Very pleased overall.

Gift for my husband he absolutely loves it! Said he feels like a bad ass just wearing it
