Theft protection system for motorcycle, comprises two consecutively activated alarm and stop devices

摘要

The first theft protection unit (20) is assembled of an external device (39) providing an identity code (49) to be checked by an internal device before the vehicle can be started. A second unit (21) identifies a vehicle as stolen and releases a visual (35) and an acoustic signal. It also initiates a stop of the power supply in such a case. Both units (20,21) are connected by a transmitting duct (38). The first unit (20) informs the second unit (21) about the false identity. There can be additional sensors positioned at the seat or the lid of the fuel tank.
