Scorpio SR-i900R Security System

The Scorpio SRi900R Security System is a hands free security system featuring an FM remote receiver, Three-Stage Perimeter Sensor and Remote Ignition Disabler. The Remote Ignition Disabler allows the user to remotely cut off the engine in case of hijack or “hot wiring” while the Programmable Perimeter Sensor with warn away detects motion around the bike, protecting saddlebags, luggage and other accessories.

By incorporating RFID, the system is able to know when the remote is in range, allowing the user to never have to reach for the remote to protect the bike. The SR-i900R transceiver is capable of receiving alarm triggers from up to 1/2  mile away from the motorcycle.

The SR-i900R utilizes a built in accelerometer that detects both impact and changes of angles with a high degree of accuracy. It allows the module to be placed in any position or mounting angle and requires no adjustments.

SR-i900R includes TRS-9 remote transceiver, MCM (main control module), RFID antenna,  universal installation kit, accessory harness, main harness, built in Back-Up Battery, Three-Stage Perimeter Sensor and Remote Ignition Disabler.

What's better than watching someone stealing your bike?
Remotely disabling the ignition and watching them go down. (I know, it's not nice. You don't need to go about telling me the legal aspects of harming a thief)
So most people would buy this as an option to protect their motorcycle. That's great. You do have to remember that most motorcycles get stolen by shady people who come by, pick up the bike, load it into a van, and drive away. If you're truly concerned regarding someone stealing your motorcycle in public, you're better off buying a heavy duty chain and chaining your motorcycle to a fixed object. This alarm is more for anti-tampering purposes.
So let's begin with the parts breakdown.
You have your main alarm. The unit is great. 120 dB is no joke. This thing WILL attract attention if it goes off. There's even a backup battery so if it is armed and someone disconnects it from the battery, it will immediately begin sounding off. If you're installing this on a R6, do not buy the factory harness. The last time I bought a factory harness thinking it'd be easier, it was actually more difficult. The wires were wired wrong from factory and swapped the grounding cable and brake signal with the turn signals. Because of this, every time I signaled left, it'd set off my alarm. You're better off cutting the sheath over the wires with a razor and installing using the generic harness that's provided with the setup. Do not trust the clamps that are provided to break the sheath. They're not sharpened to break any sheathing and you might not be able to get a good connection. Also, when wiring it, do not wire the brake wire (from the alarm) to the brake on/off signal wire (on the bike). Wire it to the running brake light wire, otherwise you're also going to trigger the alarm every time you brake. Note: this applies to the R6. I don't know how the harnesses for other bikes are. The alarm also has incorporated into it its own lean sensor and knock sensor. Hitting the bike or moving it to an upright position from being on the kickstand will set it off.
Next up, we have the remote. This little thing lasts a while. I've gone a week and a half without recharging the remote (I can't accurately gauge how much battery life is still in it because the battery level in the actual remote fluctuates). You will have to write down the remote's serial number somewhere just in case you lose it and need to get a replacement remote. The screen is blue backlit. A nice part of the remote is that when you arm and disarm the alarm, it will show you your battery's current voltage. It's a nice reference to have, especially if you're not using a battery tender. There is one downside to it displaying the voltage though. The backlight usually cuts out before it displays the voltage. Also, the remote operates using two different means. You have the regular wireless alarm frequency, then you have RFID. Nothing to be really concerned about. It just means that the alarm will disarm if you bring the remote next to the bike. This is nice because it's more of a set and forget. You don't need to disarm it when you start it, it'll arm and disarm as you put turn on your bike or turn off your bike, but you do still reserve the option to do so without being near the motorcycle.
Perimeter sensor is next up on the list. This thing is pretty easy to install. No custom wiring or cutting into the harness. Only downside is that this thing isn't waterproof. If any water gets into it, you'll need to get a new one. I live in California, so I don't experience much rain, but if you live in a rainy area, put a plastic bag over it and zip tie the end so that no water will get into it. The sensor works fine with a bike cover and won't trigger prematurely. Also, the rain will not set off the perimeter sensor.
Finally we have the remote ignition disabler. This one is a bit more tricky as you do have to cut into either your fuel electrical lines, tilt over (lean angle) sensor lines, or your ignition. There's no way around it and you also have to remember, these things fail. Ultimately, this is the reason people don't recommend alarms. If it fails, you won't even be able to run the engine. I got lucky as my ECU solution had a plug that served as an extension for the lean angle sensor. I spliced that wire that was coming out of the plug and wired in the remote ignition disabler into it. It works flawlessly. How you choose to do it will probably differ from my solution. Note: the ignition disabler is not immediate. It gives whoever is stealing your bike 15 seconds of engine time before it cuts it off. It will not reset unless you bring the remote near the RFID wire so the bike will be disabled until then.
Overall, I'm satisfied with the alarm system. I haven't had any battery issues and my remote ignition disabler has not gone bad. I've had the system for about 3 months now and am just waiting to see if anything will go bad. If you don't have the technical know how of how to identify wires based off of your wiring diagram, tap into electrical lines, splice wires to add a circuit, don't do it yourself. Bring your motorcycle to a shop that does know how to do it, otherwise you'll just risk a lot of down time.

Great potential but it needs work
First off let me start by saying i am not sure if i bought this alarm from Revzilla cause that was over 2 years ago and the review is only for the product not for Revzilla, which by the way does an PHENOMENAL job in the industry!!!

PROS of the alarm
-It is loud
-The little remote is quite useful
-It covers every security aspect (perimeter,ignition and back up battery)
-Installation in relatively easy

CONS of the alarm
-Too expensive
-Alarm only goes off for a minute or so and then it stops
-Drains the battery, which defeats the purpose of leaving your bike stored (or not) with the alarm
-I accidentally broke the remote so i ordered a replacement. Followed the instructions, called customer service but i still couldn't get it matched to the alarm again. Had to send back the whole alarm for them to match it and then ship it back to me matched
-Info on colored wiring is a bit off

All in all, now i have totally removed the alarm and i to be honest, i don't think i will be using it again. Yes, it is loud but whats the point if it only goes off for a minute?! I'd rather it went off forever and i need a new battery than lose the bike hahahaha

Works Very Well. Honda CB500x ABS 2014
This alarm was installed on my Honda CB50x ABS (2014) in about a half hour or so.
I used the factory connectors (Honda 6, I beleive) and it was a snap.
The proximity sensor is VERY sensitive so, I turned mine all the way down and it works just as your put your body over the motorcycle seat. The Ignition disable is a later feature I'll install later. It works well in the rain and after a heavy rainstorm in Portland, so I know it's waterproof. The sensors also do not seem to have "false" alarms if you turn it down to the lowest or second lowest setting.
The shock sensor works pretty well too and the alarming motorcycle will transmit that to your little handheld reciever it comes with (two way radio).
It works well from a few hundred feet away but I haven't tested it further than this. I'm sure it works several hundred (more) feet away.

My favorite feature is that the seat protects it from water, the alarm can automatically turn off as you walk up to the motorcycle and put the key to ignition "ON" and makes a cool beep sound. Not sure why that's so cool to me but I guess I love high tech gear....and this is high tech!!!

I would certainly get this!

State of the Art Alarm
I installed this alarm on my BMW G650GS. As I am travelling through Latin America and use soft bags it gives me some sense of security. The proximity award works well although in some cases I have to turn it off if too many people walk by the bike. The remote works at about 100 yards. The RFD works perfectly. The build is very robust. The remote stays charges a couple of weeks.The only bummer is the charger for the the remote is massive and wont work on 220V. If you want 220V you have to buy a different massive charger. They should make it charge on micro-usb.

Tough to Recommend, User interface needs a lot of work.
Does this Alarm do a good job of making me feel my ride is protected?
Yes, it most certainly does. I live in an apartment complex and I cannot see my bike from my apartment. I wanted piece of mind. When I'm in my place, I'm about 60 feet away from my bike with several walls between us. The remote is still able to receive signals from the bike. This concludes the positive aspects of my review.

Was this alarm easy to install?
Not for me. I'm at best a novice with electronics or wiring much less motorcycle wiring schematics. I took my bike ('12 Griso 1200) to my local MG dealer and had them put it in. Even so it took them the better part of 6 hours to work it out. There isn't much in the way of user friendly instructions. That goes for the user manual as well.

Is this alarm easy to use?
NO!!! Easy to use products are designed with the user in mind. This product was most likely designed by engineers who are very good at designing and constructing quality components that work flawlessly when operated by other like minded Vulcans but who don't have any experience with making a user friendly product for us faulty humans. Don't get me wrong this alarm works great. Using it is a stressful, potentially embarrassing experience. In short using it sucks.

This system comes with a wide array of great features that have a huge amount of adjustability. But for all the great features you get with this alarm, you have 2 buttons with which to work it all out. Neither of which is actually marked or designated button 1 or 2. The manual gives instructions on which button to press to do this or that but then accompanying illustrations just show a line pointing towards the left side of the remote, not to a specific button. I can assume button 1 is the top but inevitably I just end up mashing one or the other until i get the desired result.

At just about every button press you get an accompanying loud chirp from the alarm to confirm your choice. None of which means anything to me other than to scare the !@#k out of me, and annoy my neighbors. The only time I should hear any noise from the alarm is when a thief is having his way with her. Not when I'm trying to manage the alarm features. It really shouldn’t be this nerve racking. I literally have to take a calming deep breathe every single time i try and mess with anything on this system. A bit like using chopsticks to disarm a bomb.

So far the rules to live a peaceful life with this alarm is just remember to always have the remote on your person because the alarm knows the difference between someone with the remote and someone without it. Don't let anyone near your bike unless they have the remote on them or you manually turn off the alarm by pressing and holding button 1, or 2, no wait buttons 1 and 2? ALARM ALARM ALARM!

What could be done to make any problems better?
#1 Simplify, simplify, simplify. More thorough installation instructions for people not used to such procedures. Less confusing user manual.

#2 Loose the remote and make it a smartphone app. Anyone spending this much money on their luxury vehicle’s alarm system is already going to own a smartphone. Hire some user interface professionals and a software development team to design a simple easy to use app that manages all the settings and features. Then test your product with everyday people. If your testers can figure it out without being coached you’ve got a winner. If you can’t manage the smartphone app due to Bluetooth or wi-fi being to weak of a signal, then completely redesign the RF remote to be easy to use just like the app i described above.

Overall verdict?
Owning and riding a motorcycle for me is a bit like trimming a bonsai tree was for Mr. Miyagi. If I could go back in time and not have spent the money on this alarm, and the money it cost to have it installed I would. I’d much rather risk an unprotected bike than have something as tedious as this alarm get between me and my ride.

Awesome alarm system, very well design easy to install, my only concern is the range of the remote control signal, when you enter in buildings the signal is lost, on open areas is really effective .

Increased overall protection
This is a great feature to any bike. Along with a disc lock brake and with this alarm really keeps my mind better at ease since I live in a apartment complex where my bike is exposed to all. Installing can be tricky at times. I would highly and strongly recommend if you can, get the "Factory Connector Kits" because they seriously make the installation a plug and play. Without it I would have had a very hard time figuring out the connections. I wished the ignition kill switch would have been made easier to install. You have to splice your cables and that's something I was uncomfortable in doing to my bike. It's a pretty small package but given some bikes that has very limited space like my Ducati Monster S2R, it can be hard finding space where there isn't any. One major tip would be to have the main unit as flat as possible. I first tried installing the unit under my side fairing but upon testing, the tilt sensor didn't work. Re-reading the manual I saw that it needed to be leveled to work the best. Only wised the signal would be stronger that can pass through concrete walls. As soon as I'm 100' into my building at work, I lose connection with the remote. But it's still nice that the alarm will do it's thing, just that I won't know anything has happened until I get close enough. Oh, and the alarm is loud. Which is good ;)

This is the best Security alarm hands down. I wish I have this in my car. Perimeter sensor is awesome, nobody gets close to my bike lol! Tilt sensor is awesome as well. I like how the remote alarm sounds so loud. Easy install, no wire cutting needed as long as you buy the factory harness (depends on the bike). took me just 10 minutes to install this with the factory harness.

For security reasons. The KTM 1190 RC8R is a very unique bike. There arenâ??t many around especially the black and orange version which I recently purchased. After spending hours researching on Google and Youtube, Scorpio SR-i900R security system seems like the best option out there. I considered LoJack at first but after visiting their website, they no longer offer security systems for motorcycles.

To deter thieves from attempting to take the bike. If it's parked in a not-so-good area, I can at least respond to the two way alarm system before it's stolen. Also, it prevents people and their little kids from trying to "sit" on the bike, or touch it. It will warn them when they get too close.

Does this alarm include a tracking device?
A shopper on Aug 15, 2013
BEST ANSWER: The SR-i900/R does not have GPS/Tracking ability. The Ride Core-S is a separate system and the most current model with GPS communication.
why is your price is too high ?, it is selling for $249 on official website
A shopper on Mar 22, 2014
BEST ANSWER: Yeah, It is definitely $315 on their website for all of these components
What's the difference between the SR-I900 and the SR-I900R? If you add the accessories manually on the SR-I900, there a difference of $30.10 if you compare with the SR-I900R model (with this model being more expensive).

Is there a difference between the two for me to be paying this extra $30.10?
A shopper on Jan 13, 2016
BEST ANSWER: SR-1900R comes with an engine imobilizer. I've actually had this alarm system on my bike since April 2014 and it's great. I even installed it myself. It's worth it if you ask me.

Is there a factory connector kit available for the 2012 Kawasaki ZX-14R?
A shopper on Dec 28, 2014
BEST ANSWER: Hi - i bought the scorpio i900r for my 2012 R6. The connector kit is available on the scorpio website. If your year / make bike is not listed speak to a representative and they will get you the correct connector kit. Hope this helps.

I am looking for a good alarm system, I was wondering if this would work for a new Kawasaki Z800, is there any issue with the connectors in Europe? I am located in Germany.

Is it compareble to the M+S Legos 4 Alarm system?

Thank very much!
A shopper on Jun 24, 2014
BEST ANSWER: The SR-i900 works well any motor cycle due to the universal harness. The connector kit part number KAW-6 should work for you.
