A motorcycle alarm is a device that allows you to increase the security around your bike by using your own vehicle to signal when it's being tampered with or robbed. Motorcycle Alarms come in two forms: Wireless and Wired.
For maximum security, your Motorcycle Alarms should be both hard-wired to the receiver, with a fuse for all three types of alarms, meaning that there's no chance whatsoever of them being unplugged while you're away. That's why some motorcycle security systems have such strong wires, even though you're only securing your battery or remote. These kinds of wires make it very easy to cut through and disable the alarms, even if they work in conjunction with other kinds of locks, such as with a deadbolt or a conventional deadlock. Because of this, it's always a good idea to take the time to make sure that you have the right Alarms for your bike and your needs.
While most motorcycle alarms will work just fine if a thief simply removes your keys, if your bike has a battery or an internal combustion engine, then you'll need to have a working battery backup just in case. This doesn't mean you'll have to leave your bike plugged in all the time, but if you ever fall victim to a break-in, then you need to have a way to disarm your bike in a safe manner. The best option for this is to have a battery backup that you plug into a spare outlet and simply connect to a power supply cord. This prevents the battery from being drained, and it also ensures that your motorbike security system will actually work on your bike in the event of a break-in.
