well does it work? If they just throw it into a van can they get away with it going off? Do they know how to disarm quickly? So lets start with a basic motorcycle alarm. This is going to be a “Shock Alarm” an if its something you picked up on eBay from China it may or may note be effective. Perhaps the “shock” part of it is ineffectve. We have found that the “shock” part of any alarm is the weakest part of the alarm. We say that because some alarms you can touch the bike so very gently and it goes off and others, you could sit on it and have to bounce around on it before it goes off. So the next part is the “Tilt Alarm”. This is where if the bike is on its kickstand and is move into the upright position, the alarm will go off. this we gound quite consistent and effective in almost all alarms that have “tilt”. It works well. Now most alarms you look at have these two components: “Shock & Tilt”. The better alarms that we will discuss later have greater sensitivity while the cheaper ones, but now all have less “shock sensitivity” but good “tilt sensitivity. Here’s what we don’t like. A thief could carefully cut the chains to the bike if they are just using basic chains, so now there is nothing to stop them from pulling a van up and then 1,2,3 grabbing it and pushing it into the van and yes the alarm will go off, but its in the van with the doors closed. Best Solution: “Shock, Tilt, Perimeter Alarm”, the most expensive alarm. With this alarm, the perimeter component is beautiful. Walk to within a few feet of the bike, the alarm goes off. Again, a thief can’t even inspect the situation of this potential steal, that loud alarm has the thief outta there. The thief is also aware that when the alarm goes off, most systems send a signal to the remote unit the motorcyclist carries and lets them know the unit has been triggered. Thieves know this. Perimeter alarm components have ups and down sides. The upside is that the sensitivity is adjustable from several feet to a foot or so away. The downside is that we hear from users is that sometimes the wind can set them off, causing a hassle, an annoyance and a possible dead battery. We have heard people say that alarms drain the battery. In our testing, not so. Ok, perhaps if you are not riding your bike frequently, maybe just weekly or every 2 weeks... the battery could get its charge lowered. But if you are riding every day or every other day, no problem. One thing to note. There is no one solution for bike security. Great security will take all categories to protect your motorcycle. While motorcycle alarms are a fantastic deterrent, a would be thief could still get the bike into a van dam quick and close the doors with the 120db sound confined to inside the van. So a chain lock would greatly assist if parked indoors. On the street, your alarm is likely on its own, unless teathered to a post or something. A disk lock will do nothing when 3 guys pick the bike up and throw it into a van.But a strong shrieking siren alarm does deter would be thieves... particularly when they are only within a couple of feet. One thing we did not mention was the paging aspect of upscale alarms. Yes good idea, but if the pager is
