Where’s my motorcycle?! With the rLiNK GPS Security System SR-i1100S ($499.95, data plan not included), you’ll never ask that question again. The GPS-based unit detects ignition status, location, movement, shock, speed and tilt. If your motorcycle is started and/or moved, rLiNK knows it. This information is then relayed to a secure server and accessed through the free iPhone application or with any computer or smartphone. Theft tracking and recovery merely scratch the surface of the rLiNK’s many capabilities. The Group Ride feature, for example, allows users to share information, such as trip stats and weather notifications. Updates can even be sent to other riders using Facebook and Twitter accounts that are linked to the system. Optional accessories include a multi-tone 120-decibel siren and starter disable.
