Handsfree systems are particularly important on motorcycles, and Cardo Systems, Inc. seems like they have a decent solution here with their scala rider TeamSet Pro.  The device features a boom mic and speakers that attach to the inside of a motorcycle helmet, allowing you to connect to your mobile phone, GPS unit or media player via Bluetooth.  The device also allows you to talk with other riders via an intercom system.

No word on pricing or availability, but Cardo has a pretty solid network of distributors in the US, so you shouldn’t have a problem finding this device when it’s released.
