I have the prior generation scorpio. The perimeter sensor can be a pain in the ass depending on where you park. If your close to a sidewalk, it goes off with every person that walks by and I have mine adjusted pretty low. I will tell you that they can eat your battery if your not running your bike at least once a week. I let mine set for a month and the battery was gone. Course it was set with the alarm on. Now if it is not going to be rode for more than two weeks, I put the tender on it to keep the juice up. Just some things to think about. But I would never have a bike without one again.
