Aftermarket security system.
The Sirens are kind of useless in a big city nobody pays attention to sirens going off, it happens all the time. On the other hand it makes people turn their heads and take a look and thats what thieves dont really want, attention.
I agree the Harley system is pricey but it has its own advantages:
- hands-free operation when you have the FOB in your pocket the bike appears to you as if there is no security, just jump on it and start it.
- very high security, the FOB signals can not be hi-jacked by thieves and re-send to disarm the security the FOB IDs are assigned using laptop at the dealers, and they are never transmitted through the air. No hijacker can impersonate your FOB
- Besides disabling the starter motor the Harley system disables the Ignition Controller as well. And thats not done by a wire but using highly encrypted digital password communicated on the vehicle bus between the security module and the ignition module
- A thief cant walk to your bike, put his own security module and start the bike the Ignition Controller remembers the password of the original security module.
As for the siren coming on when moving the vehicle around well, that may be a pain in the *** if you are in a habit of frequently repositioning your vehicle in the garage and dont carry the FOB with. On the bright side the siren never comes full blast right away; it will first give you two gentle chirps to remind you to leave the vehicle alone and go get your FOB.
On rallies and big biker gatherings where vehicles are parked close to each other the perimeter sensor can be kind of nuisance it trips the system anytime somebody walks by, and some rough fellow can give your scooter a kick in the groins.
Another consideration is current drain- it will deplete your battery faster.
Then yet another consideration a good immobilizer is always better than a good noise-maker (siren). Siren can be easily defeated just spray some silly spray on it, or put a scotch tape over it if you can access it, and its done.
