  • COMMUNICATE HELMET TO HELMET
    WITH MESH INTERCOM™

    Sena’s Mesh Intercom™ allows riders to communicate hands-free with any other Mesh user (R2 EVO, R1 EVO, M1 EVO) within a half-mile range (900 meters) with the touch of a button. Multi-channel Open Mesh offers 9 channels, letting you switch between groups on different frequencies. Sena’s Mesh platform offers flexibility by allowing riders to come in and out of range while keeping the rest of the group connected. Whether you are riding with one other person or a group, the R2X will take your ride to the next level. Audio is delivered through integrated speakers located above the rider’s ears, which allows for awareness of surrounding sounds such as traffic, unlike in-ear buds. Located in the front of the helmet is a built-in microphone that houses Sena's patented Advanced Noise Control™ technology, picking up and transmitting your voice clearly.

  • PREMIUM FEATURES
    FOR COMFORT AND SAFETY

    The R2X houses an integrated LED taillight. With three brightness settings, you can enhance rider visibility based on your particular lighting situation. The R2X is also safety-certified and built with a protective in-mold polycarbonate shell. The helmet, lined with removable and washable inner padding, features a smooth nylon chin strap, and a spin lock for a secure fit.

  • SMARTPHONE CONNECTIVITY

    Bluetooth® technology allows you to connect to your smartphone, enabling you to tap into Alexa Built-in, make phone calls, listen to music, hear GPS navigation, and even connect to fitness apps. The Sena Cycling App allows riders to conveniently take control of the R2X's features. Through the app, you can create groups of friends to easily connect with, control taillight settings, manage multi-language voice prompt selection, and access the Quick Start Guide on the go.
