The Gorilla alarm is a cake walk. Install in less than 20 minutes. No ignition kill to play with . Mount main module, mount tilt sensor, connect to power, program remote, done. I used one for a while but thieves stole that bike so how good was it really? Another $100.00 and your in the Scorpio SR-i500 price range. Much better system. Word of advice...If you use the Gorilla don't install the warning led light. All that does is let criminals know you have an alarm and they can come prepared to defeat it. I know cause there is an 04 Blue/Silver still missing that had a Gorilla alarm installed on it.
