Reviews (0)


The 50R Mesh 2.0 Intercom couples Sena’s most advanced technology to date with a low-profile user friendly design.

With its sleek good looks, rugged durability, and next-level technology it represents Sena’s flagship offering as well as setting a new motorcycle communication standard.



The 50R features three different intercom modes: Group Mesh Intercom, Multi-Channel Open Mesh Intercom, and Bluetooth Intercom.

With Group Mesh, you’ll create a single, private group that supports up to 24 participants over a range of up to 5 miles / 8 km (min 6 riders @ 1 mi / 1.6 km intervals)

Users are invited into Group Mesh, giving added control and privacy.

Multi-Channel Open Mesh lets you communicate with virtually anyone participating in the Mesh 2.0 network within a range of up to 5 miles / 8 km. Open Mesh also features multi-channel options, an industry-first! With nine channels available, you can switch to a new frequency for conversations with different riding groups within the larger Open Mesh group.

Finally, traditional Bluetooth Intercom mode rounds out the third communication option included. All riders and their ever-changing riding scenarios will surely benefit from the incredible flexibility and technology engineered into the 50R Mesh 2.0 and Bluetooth intercom modes.


Mesh 2.0 delivers a robust new level of reliable intercom connections and intelligent routing management. This innovative system has resulted in a staggering increase of 80% more data being transferred across harsh and challenging conditions, providing superior intercom audio quality with a rock-solid connection.

Additionally, information sharing between connected devices is happening in real-time at mind-boggling speeds, allowing Mesh 2.0 to instantly assess the optimal path for delivering messages to all participants in the network.

Stress tested and proven by over 140 global riders during the International GS Trophy 2020

How did the riders feel it performed?


The newly redesigned in-helmet speakers are optimized for both physical comfort and impressive audio performance. These particular speakers have been designed with a beveled taper and easily fit in the speaker pockets of a helmet, giving the rider a comfortable experience. But exterior design is nothing if the audio output doesn’t meet expectations. With a marked increase in volume, bass boost, and clarity, these all-new HD speakers not only meet expectations but shatter them.


Take control of the 50R without lifting a finger. Voice commands give you hands-free control of the 50R, operating select functions, including entering Open Mesh or answering a phone call. Simply say a command, and the 50R will act for you. The 50R supports multi-language voice commands, responding to eight different languages, including English, French, German, Spanish, Italian, Chinese, Japanese, and Russian.

The most powerful upgrade to the 50R voice commands is the new direct, hands-free access to Google or Siri through your smartphone! “Hey Siri, directions to the nearest hotel, please!” “Hey Google, what’s the weather forecast  today?” No buttons, no other preliminary commands. The 50R connects to everything Google Assistant and Apple’s Siri have to offer…all while you’re rolling down the highway!

Access phone numbers, music apps , ask for directions .  Simple & effortless.


50R power running low? With its new high-density battery and technical improvements to the Fast Charging feature, the 50R will charge 30% faster than previous Fast Charge units.

Plug it in for just 20 minutes, and you’ll get 3.5 hours of Mesh Intercom™ or 6 hours of Bluetooth intercom operation.

A full charge of the unit happens in just an hour and provides 8 hours of Mesh communication or 13 hours of Bluetooth intercom talk time.

Differences between the 50S and 50R

The  50R is the slimmer of the two units and is designed for off road users who wear neck braces, such as the Leat brace. It connects to the helmet either via non destructive 3M adhesive tape or removable Velcro       (both options supplied). This allows for the 50R to be flush with the bottom of the helmet and it will not interfere with a neck brace.

The 50R is operated via three ultra-low-profile buttons, making it further streamlined. Contributing further to its reduced form factor are two included microphones : a wired boom mic & a wired button mic.

The 50S has a slightly thicker form factor and connects to the helmet via a clamped base ( the same base as the Sena 30K ). This base has an integrated  boom microphone as well as the 50R’s wired boom mic & wired button mic, as standard. There is also a 3.5mm port for earbuds integrated into the base of the 50S ( to use earbuds on the 50R will require the optional 10R Earbud Adapter Split Cable (part #: 10R-A0101).

The 50S is operated vis Sena’s tired and tested glove friendly Jog dial.

You’re going to get an hour more talk time from the 50S battery as opposed to the smaller, sleeker battery on the 50R.

Both house Sena’s most up-to-date tech in both hardware and software.

Both are incredible pieces of class leading machinery.
