The F4MC allows bike-bike toggling with up to four riders within a range of 1/2 a mile.

The system receives GPS voice instructions and allows communication with a pillion, or other group riders. Phone calls can also be made and received inside the helmet including automatic radio muting for incoming calls.

You can listen to music from a stereo A2DP connection, or MP2/iPod via c able. It also has a built-in FM radio with RDS, as well as a preset memory to save up to eight stations.

For real ease of use the F4MC can be used with interphone's remote control, which is fitted to the motorcycle handle bars and means the whole system can be used without loosing contact with the motorcycle.

Standard features – that are also present on other units in the MC range - include music sharing mode, so rider and pillion can listen to the same stereo music. Also, a two-way volume setting that increases conversation in the intercom mode as the volume can be set in two ways; one for open-faced helmets and another for full-faced.

The F4MC is available in UK dealers and priced at £169.99 for a single unit and £299.99 for a twin set.
