The con with the alarm, as I found out after I had mine fitted, is that it switches itself off after a few days....
Yep! About 7 days. Even if you have it on an Optimate. It is to save bike battery life.
The answer is to re-activate once a week. If mine isn't being used I just turn it on, then set the alarm when I turn it off.
Living under a cover, I always check it is still my bike under there and not some cardboard cut-out. This happened to a mate of mine back in my air force days. Bike parked outside mess, under cover. Guy went out to go home on it one weekend and all that was under the cover was a pile of cardboard boxes biffed into a rough bike shape! Bastards!
