Best Motorcycle Alarm Systems in 2026: 5 Options Compared

Monimoto 9 is a GPS motorcycle alarm that calls your phone when your bike moves without its Key Fob nearby, then sends the bike’s location to the app. That is why it leads this comparison.

A siren can make a thief think twice, but it cannot tell you where the bike went. Most riders need an alarm that does three jobs: tell you something is wrong, show you where the bike is, and make the theft harder. We compared five motorcycle alarm systems against those three jobs, using each brand’s own published prices and specs.

TL;DR

• Monimoto 9 ($179 + $49/year): calls your phone, then sends location updates. Wireless, IP68, rechargeable battery that lasts up to 12 months. No siren.
• Scorpio SRX-900 ($199.99): 125 dB siren and a hands-free remote that pages you. No phone alerts or GPS unless you add Rlink.
• ABUS Detecto 7000 RS1 ($175.99): a hardened-steel disc lock with a 100 dB alarm. Blocks the wheel, but sends no alert anywhere.
• Scorpio Rlink GPS ($109.99 + from $6.99/month): wired phone alerts with 30-second reporting while moving. North America only.
• Monimoto 7 ($129 + $49/year): the same call-and-locate alarm on two replaceable AA batteries that last up to 24 months.

How we compared these alarms

We did not run hands-on tests for this article. Each product was compared on the specs and prices its maker publishes on its own US store, checked on October 4, 2026. Where a maker does not publish a figure, the table says “Not published” rather than guessing. Monimoto figures come from Monimoto’s own specifications. Prices are in US dollars and can change.

The three jobs a motorcycle alarm can do

We scored every product on what we call the Notify, Locate, Deter test:

• Notify: does the owner find out, wherever they are?
• Locate: once the bike is gone, can the owner see where it is?
• Deter: does it make noise or physically slow the thief down on the spot?

The job that matters most is the one a siren cannot do. NICB reports that 44,564 motorcycles were stolen in the US in 2025 and only 41% were recovered (NICB, 2026). Noise helps before the bike leaves. Location is what helps after.

The 5 best motorcycle alarm systems in 2026

1. Monimoto 9: best for alerts on your phone and finding the bike

The Monimoto 9 is a silent GPS alarm. It sits in Armed mode. When it feels movement and cannot detect the paired Key Fob, it switches to Alarm mode, calls your phone and sends push notifications with the bike’s location. It passes two parts of the Notify, Locate, Deter test: Notify and Locate. The Key Fob is what lets it tell you apart from a thief, a design choice covered well in owner recognition explained.

It needs no wiring. It hides under the seat or in a headlight or tail light housing, fixed with releasable zip ties, and runs on its own rechargeable battery. That battery lasts up to 12 months between charges. Because it does not draw power from the bike, cutting the bike’s battery does not switch it off. It uses an integrated eSIM on the LTE Cat-M1 network, so it does not depend on your phone being nearby. Indoors, where GPS cannot reach, it falls back to cell tower and Wi-Fi location.

Trade-offs: it has no siren, so it does nothing to scare a thief at the scene. It needs a $49/year subscription for its cellular connection (the first 2 months are free).

2. Scorpio SRX-900: best siren alarm

The Scorpio SRX-900 is a classic hardwired alarm and the strongest Deter option here. Its main module has a 125 dB multi-tone siren with shock, tilt and ignition sensors built in. It can also sense when the bike battery is cut, and an internal backup battery keeps the siren sounding if a thief disconnects it. A hands-free RFID remote arms and disarms it as you walk to and from the bike.

Alerts go to that two-way paging remote, not your phone. Scorpio says plainly that the SRX-900 has no GPS tracking or phone alerts unless you add its Rlink module. It wires to the bike’s 12 V battery with a 3-wire harness, and plug-and-play kits exist for many models.

Trade-offs: you only hear about a trigger while the remote is in paging range, and Scorpio does not publish that range. No IP rating, weight or dimensions are published (Scorpio describes it as waterproof).

3. ABUS Detecto 7000 RS1: best disc lock alarm

The ABUS Detecto 7000 RS1 is a disc lock with an alarm built in. 3D motion detection sets off a 100 dB alarm for 15 seconds, then the lock re-arms itself. The bolt and body are hardened steel with an ABUS Extra Classe cylinder. It weighs 1.28 lbs.

It scores on Deter twice: noise, and a locked front wheel that keeps the bike from being ridden off. It needs no wiring and no subscription.

Trade-offs: it does not notify you and cannot locate the bike, and it does nothing if the bike is lifted into a van. You also have to fit it and remember to remove it before riding. ABUS does not publish its battery life or IP rating on the US store.

4. Scorpio Rlink GPS: best wired phone-alert tracker for North America

Scorpio Rlink is a small GPS unit that sends text and push alerts when someone touches, starts or moves the bike. It reports every 30 seconds while the bike is moving and is rated IP67. It wires to the battery with two leads, and you can add it to an SRX-900 for $64.99.

That gives Rlink Notify and Locate, and paired with the SRX-900 it covers all three jobs. On its own it costs $109.99, with plans at $9.99/month or $6.99/month prepaid every 2 years.

Trade-offs: coverage is North America only (US, Canada, Mexico). It depends on the bike’s battery, and Scorpio does not publish whether Rlink has a backup battery of its own.

5. Monimoto 7: best for the longest battery life

The Monimoto 7 works exactly like the Monimoto 9: movement without the Key Fob, a call to your phone, then location updates. The difference is power. It runs on two replaceable AA lithium batteries that last up to 24 months, so it suits a bike that sits in storage for long stretches.

Trade-offs: it is bigger and heavier than the Monimoto 9 (95 g against 58 g) and rated IP65 rather than IP68. Like the Monimoto 9, it has no siren and needs the $49/year subscription.

Three-year totals are the device price plus three years on each maker’s standard monthly or yearly plan, with no prepay discount.

Where each one wins

• Monimoto 9 wins when you want to know about a theft wherever you are and see where the bike goes, with nothing to wire and no drain on the bike’s battery.
• Scorpio SRX-900 wins on noise. At 125 dB with a backup battery and a hands-free remote, it is the strongest deterrent at the scene.
• ABUS Detecto 7000 RS1 wins for street parking where you want a physical barrier and noise, with no fees at all.
• Scorpio Rlink GPS wins on reporting rate, every 30 seconds while moving, if you ride only in North America and do not mind wiring.
• Monimoto 7 wins when the bike is stored for months and you would rather swap batteries once every two years than charge.

What a GPS alarm cannot do

A GPS alarm reports location. It cannot keep a thief from lifting the bike, and GPS signals do not reach inside metal containers or deep underground. Monimoto falls back to cell tower and Wi-Fi location indoors, which is less precise than GPS. That is why many riders pair a silent GPS alarm with a disc lock alarm: the lock slows the thief down, the GPS alarm tells you and shows where the bike went. If you already carry an AirTag, our AirTag comparison covers how the two work together.

What a real recovery looks like

In a story we published in September 2026, a Monimoto rider staying at a hotel in Apt, southern France, had his motorcycle moved at around 4 a.m. His phone was on Do Not Disturb, so the alarm call did not wake him. He saw the missed call later, and the hotel concierge called the gendarmerie. Officers followed the tracker’s location and caught an organized group loading bikes onto a truck. His bike and several others were recovered within hours, and the thieves were later convicted. The full account is on our success stories page.

The practical lesson: an alarm that calls you only helps if the call gets through. Add Monimoto’s numbers to your phone’s favorites so they ring through Do Not Disturb. The alarm sequence is the same on the Monimoto 9 and the Monimoto 7.

Which motorcycle alarm should you choose?

Start from where the bike sleeps. In a locked garage at home, a siren you can hear may be enough. On the street, at work or on a trip, you will not hear a siren, so you need an alarm that reaches your phone and shows where the bike goes. For most riders that is the Monimoto 9: it covers Notify and Locate with no wiring and no drain on the bike. If you want noise as well, add a disc lock alarm or a siren system on top.

FAQ

Is a Monimoto motorcycle alarm worth it if my bike is insured?

Insurance replaces your bike. Monimoto helps you find it. NICB data shows only 41% of motorcycles stolen in the US in 2025 were recovered, and a claim still means an excess, paperwork and a wait. A Monimoto GPS alarm calls you when the bike moves and shows where it goes, which gives you and the police something to act on.

Is Monimoto a better anti-theft device than a disc lock alarm?

They do different jobs, so many riders use both. A disc lock alarm makes noise and blocks the wheel at the scene. Monimoto calls your phone and sends the bike’s location once it moves, which a disc lock cannot do. Our alarm buying guide explains how to layer them.

Does Monimoto drain the motorcycle battery?

No. Monimoto runs on its own battery and is not connected to the bike. The rechargeable Monimoto 9 battery lasts up to 12 months between charges, and the Monimoto 7 runs up to 24 months on two AA lithium batteries.

How does Monimoto alert my phone when the alarm goes off?

Monimoto calls your phone, then sends push notifications with the bike’s location. In Alarm mode it sends a location every 5 minutes, or every minute with the faster tracking setting switched on. Save Monimoto’s numbers as favorites so the call rings through Do Not Disturb, as one rider in France learned overnight.

Is Monimoto a wireless motorcycle alarm?

Yes. Monimoto has no wires to the bike. It fixes in place with releasable zip ties and arms and disarms itself with the paired Monimoto Key Fob, which works within about 25 m (82 ft) in open space.
