ACS-RAM is a Bluetooth communication system from Sena designed specifically for the Arai SZ-R VAS open face helmet. This compact communication system features two-way Bluetooth intercom and smartphone connectivity for listening to music, using GPS, taking phone calls, and more.

The ACS-RAM installs precisely into the internal compartments of the Arai SR-Z VAS open face helmet. The ACS-RAM speakers and microphone easily slide into the helmet, allowing audio to be received and transmitted while riding. The ACS-RAM's compact design allows it to be virtually invisible from the outside of the helmet once installed.
2-WAY BLUETOOTH INTERCOM
The ACS-RAM supports 2-way Bluetooth communication with a range of up to 500 meters and features a 3-button control that allows users to easily manage the device's functions while riding. The ACS-RAM takes 2.5 hours to fully charge and offers up to 12 hours of talk time.
SENA MOTORCYCLES APP
