What’s in the BoxClear visor included

Red rules the road. Empora is a metallic gloss red built to hit hard in daylight and glow under city lights. An evolved, tougher take on the classic crimson energy. Simple, loud and adorned with the trademark RR logo.

Made for the streets. Built to perform effortlessly the second you roll out, AT4.0 STREET feels light, balanced and planted through traffic and open stretches. Keep fatigue off your shoulders from first light to last call.

No compromise on safety or comfort. AT4.0 STREET takes all the key DNA from our signature CARBON line, delivered in a lightweight fibreglass shell that gives the perfect balance of toughness, safety and comfort. Explore AT4.0 STREET.

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 you measure for the AT4.0 STREET motorcycle helmet?

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 snug should a new AT4.0 STREET 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.

How do I stretch the inside of my helmet helmet?

Wear it. That's it. The liner compresses naturally over time and will allow more give. If pain persists after 15 hours of riding time, you need the next shell size.

How long do AT4.0 STREET motorcycle helmets last?

Five years from the date of manufacture. All EPS foam degrades over time even if it looks fine. You should always replace a helmet after any impact.

How do I clean the AT4.0 STREET motorcycle helmet liner?

Remove cheek pads. Hand wash cold. Use mild soap only. Air dry for 24 hours. Never machine wash.

Absolutely stunning helmet in person!
Dimitrios SavvidisSeptember 20 2026
Very attractive, apart from some comfort issues: Very fast delivery, very beautiful design & finish of my EMPORA (red) helmet, but the head opening to put it on, was VERY tight (note that my size is 56, which stands in the middle of the 55-57 size of the helmet I bought). Once fully fitted, it was OK, but again taking it off was unpleasantly narrow. I fitted a small child ball just at the level of the neck opening and inflated it at 7 psi. I left it for 48 hours and the result was much improved comfort. In addition, the tip of my nose may come in contact with the nose bulge of the helmet. For these comfort issues, I do not give full stars rating.
