Product Details

Scorpio SRX-900 Security System

The Scorpio SRX-900 is an effective, easy to install Security System that is compatible with just about any 12V motorcycle.

The installation is a straight forward process involving just 3 wires, one to each of your battery's terminals and one to any 12V switched wire. The SRX-900 includes a posi-tap style connector for this final switched wire, ensuring a nice secure connection without needing to break out the wire splicers.

Once the installation is buttoned up, using the system couldn't be easier. The SRX uses RFID technology to detect when a paired remote is nearby, one such remote is included, but more can be purchased and paired to the unit for bikes with multiple riders or for riders with multiple sets of keys. Once the remote is detected, the system disarms itself automatically, no need to fish around in your pocket with your gloves on. Once your ride is over and the remote goes out of RFID range (2-3 feet), the system automatically rearms itself until you and the remote return. 

For its sensing mechanism, the SRX-900 utilizes a built in dual-axis accelerometer that is able to detect both impacts and changes of angle. This allows the module to be mounted in any position or angle without reducing its effectiveness. Should the system detect that something is amiss, it will active its built-in 120 dB siren and notify all paired remote controls within a 1/2 mile.

The SRX-900 system has been optimized to use as little power as possible and uses less than half as much power as previous versions.

Top-notch alarm system
This is an amazing alarm. Ive had it for a week and it has given me no problems at all. Install is really easy if you get the factory adapters, it is just plug and play. It chirps when it is messed with and i havent had a random chirp. I also got the perimeter sensor and it also works great. You could adjust the sensitivity to your liking. Price is kind of high but it is worth the peace and mind of knowing that your motorcycle would be less vulnerable.

Saved me from a theft
I don't write a lot of reviews, but after the incident I had about a month ago, I felt it necessary to post my experiences with this alarm. I should say I have the SR-i900, but from what I can tell from the description, it's the same thing, maybe rebranded or maybe the RF range is further, I'm not sure. Anyway, I've had this installed a little over 2 years now and most of the security features have worked well as deterrents. The auto arm/disarm based on range of the transceiver has worked fine. I'm a daily rider 365 days a year if I go anywhere, so I can attest to this feature being the best. You can set the shock sensor to a couple settings and it's gone off always as far as I'm aware. The one piece I don't use is the perimeter sensor, but that's mainly because it works a little too well. I probably should just adjust it down further but I park in places that are usually very close to other motorcycles, so it's not much of a benefit for me for that reason. I just turn it off. To the theft, I had some guys break one of my forks, under the headlight, and punch out part of the ignition. This was the only thing that prevented them from completing the whole process, and I'm insanely glad it worked, though I admit I'm not sure how long it took to work since they got as far as they did. Ultimately, they were thwarted, so I have to give props as I didn't know they tampered with it until the morning. Last point this brings me to is the siren is not as loud as it could be. I live in a condo complex and it's parked maybe 50 ft from my door on the second floor and I didn't wake up to the sound but it was clearly enough to scare them away from finishing. This seems to be common with all alarms I've read about so far though sadly. On the point of anti-theft, don't let this be your only theft deterrent. Get a cover, chain, alarmed disc lock and whatever else you can afford if you live in a place where this is a problem.

35 Third world countries-zero thefts or pilferage
I travel with soft luggage on a single cylinder bike. I've used my Scorpio alarm in all kinds of dodgy places without a single incident of theft or pilferage. When you pull up to some place and there are a bunch of onlookers and you stride off in confidence, then they hear the signal and lights flash of the autoactivation unit, you have communicated " This nice bike is protected by an alarm and it is active".
I have the perimeter sensor and the disabler installed. The perimeter sensor gives a friendly indication to anyone hovering around that the bike has a sophisticated alarm activated. The disabler is very important in the sad/ dangerous occasion that you should find yourself carjacked. Just hop off the bike and let them have it. When they are a safe distance, not more than 100- 150 meters, just push the remote buttons and the motor stops. The perpetrator will, almost certainly, abandon the bike and run. I've run tests and it actually works as advertised.
The remote works up to about 200 meters in open terrain and a 100 in urban settings. If I am having a beer someplace and my beeper goes off, I just amble over to the door to see what the cause might be. It is usually something benign and I go back to my beer.
My Scorpio alarm allows me to be more relaxed and confident as I travel the world.

Safe and secure
I just installed this unit on my 2015 Yamaha R1 and it was easy as pie although my particular bike has like no room to fit the unit I found a way and am very happy with everything the RFID is the way to go keyless arm disarm is the best thing ever I also purchased the plug and play kit and not having to find that 12v to slice into is the way to go just plug and play just like it says the only thing I had issues with and it was my own fault was I had the module plugged in as I was attaching the power and ground to the battery and the alarm started sounding and didn’t stop for about 20 minuets lol wasn’t fun but as long as you read the instructions first you won’t have my problem and last thing I called tech hotline and they were the best super helpful and amazing customer service I recommend this alarm for any motorcyclist out there that wants their bike safe and secure from theft

What is the difference between SRX-900 & SR i900 ?
A shopper on Mar 15, 2018
BEST ANSWER: I have the SR i900 and the only thing I can gather from the description of the SRX-900 is the range of the transceiver appears to be much further than the i900. Everything else in the description and parts showing appears the same to what I have.

Will this work on my 2016 Yamaha R3?
A shopper on Jul 12, 2018
BEST ANSWER: It will fit any motorcycle
According to the user manual, only three cables need to be connected, excluding the turn indicators. The user manual says the turn signals would flash. I believe they will flash only if the accessory harness is used, right?
A shopper on Apr 14, 2018
BEST ANSWER: You are right, they won't flash if not wired using the accessory harness. I never connected those, just the 3 wires and it works like a charm. Very reliable system.
Does the kit include the perimeter sensor?
