hello all i would highly recommend craigslist as a sorce of purchasing bike parts because today i was on there and found a guy that was selling a scorpio alarm with the 2way remote for 75 dollars which is a super steal. as for the alarm it is the coolest thing i got on my bike it has a proximity sensor, tilt sensor ignition sensor all that fun stuff and took mins to install. keep in mind that working on bikes is not my specialty. everything was plug and play the hardest part of the install was to hook it up to the pos term on the battery other than that its probably as easy as a seat cowl. lol if any one needs help on the install let me know maybe i could help you out. it saved me 200 by not taking it to the dealer.
