The ACS-RAM is Sena’s brand new Bluetooth communication system specially designed for the Arai SZ-R VAS helmet. The compact communication system offers a two-way Bluetooth intercom and smartphone connectivity for music listening, turn-by-turn GPS, phone calls, and more.

Custom fit for the Arai SZ-R VAS

The ACS-RAM fits perfectly inside the open-face Arai SR-Z VAS helmet. The ACS-RAM speakers and microphone install easily inside the helmet, enabling incoming and outgoing audio while riding. The compact design of the ACS-RAM makes the device barely visible from outside the helmet once installed.

2-way Bluetooth intercom

The ACS-RAM supports two-way Bluetooth communication with a range of up to 500 meters (0.3 miles). The ACS-RAM features a 3-button control that allows users to easily operate helmet functions while riding. The ACS-RAM fully charges in 2.5 hours and offers up to 12 hours of talk time.

Sena Motorcycles APP

Connect the ACS-RAM to the Sena Motorcycles app to control many device functions at your fingertips. Riders can configure device settings and access the quick start guide from the comfort of their smartphone.
