Scorpio SR-i900 Security System

The Scorpio SRi900 Security System introduces the next step in motorcycle security by incorporating the convenience of hand free operation to an ultra-compact 2 way FM paging security system.

By utilizing RFID technology the system is able to know when the remote is in range, allowing the user to never have to reach for the remote to arm it. The SR-i900 transceiver is capable of receiving alarm triggers from up to 1/2 Mile away from the motorcycle.

For its sensing mechanism, the SR-i900 utilizes a built in accelerometer that detects both impact and changes of angles with a high degree of accuracy. This allows the module to be placed in any position or mounting angle.

SR-i900 includes TRS-9 remote transceiver, charging cord, MCM (main control module), RFID antenna,  universal installation kit, accessory harness and main harness.


  • Ultra low power drain main control module (MCM)
  • Built-in 120 dB multi-tone siren with soft chirp arming
  • Auto or manual arming and disarming
  • Dual-axis accelerometer for detecting impact
  • Ignition circuit sensor
  • Range and signal status display
  • Compact design (3 11/16" x 2 3/4" x 7/8")
  • Sensor violation display
  • Audible/vibrating alert
  • Smart Battery Safeguard with sleep mode
  • Motorcycle battery voltage display
  • Remote motorcycle finder/panic alarm
  • Optional Scorpio Multi-Stage Perimeter Sensor detects motion around the motorcycle
  • Optional Scorpio Ignition Disabler allows disabling of the motorcycle's electrical system and prevents "hot wiring"
  • Optional Scorpio Factory Connector Kits are available and plug directly into the factory harness making installation fast, clean and easy

Getting the job done The installation was relatively straightforward, and I consider myself a noob when it comes to this type of thing. During the installation, the alarm was accidentally triggered, and it was VERY loud. Scared the $@#* out of me! I almost exclusively use the manual on and off function, and it has worked flawlessly. Tonight, my alarm was triggered, and when I ran out to my bike (less than 100 feet from my office), I found a guy crawling under a nearby gate and he kept running. Based on the distance of the kickstand from the kickstand plate that I use, this possible would-be thief moved the bike only an inch or two before he triggered the alarm. So far, I'm very satisfied with this product, which I installed a few months ago, and I feel it was money well-invested. February 19, 2015
Great alarm system for my motorcycle! I bought this product from revzilla.com and it’s a really great alarm system for my motorcycle. It’s very very easy to install and very reliable. If you finish the installation and the alarm doesn't work as is expected, remember to do the encoding of the remote (page 12 in the user's manual). The perimeter sensor is great and you can turn on/off as you like from the remote. Two additional comments: 1. In my case I’ve bought the Factory Connection Kit for my Yamaha R6 and it was 100% unnecessary. You can do the same thing with the standard Connection Kit provided for free with the alarm. 2. For my the only feature that is missing in this alarm is the capability of turn off automatically the motorcycle and trigger the alarm when the motorcycle is running and remote control is no present. This is in case of hijacking the bike when you’re on the road. January 1, 2015

Bryn H: Yes it will, you just need to find a good mounting position for the system. Just as a heads up, unless you get the factory connector kit you will need to splice wires. But you can give Scorpio a call and see if they can get you a factory connector kit for your bike. Mar 27, 2015

Michael G: I don't have a Trumph, but I installed mine on a BMW S1000RR. T/he size of the actual unit is pretty small and I was able to install it under the seat behind my battery. I hade just enough room for the unit and wire management. It was very easy to install and only took about an hour. Most of the time was planning where I wanted to install it. Hope this helps.
