"Honestly didn't think a disc lock could be this loud. Some idiot tried to wheel my bike off the driveway and the alarm went off like a fire engine. Woke up half the street, woke up me, and by the time I got to the window he was already three yards down. Fits my Yamaha perfectly."
Kev W., Columbus, OH
I do the food delivery rounds on my scooter and I'm on and off it fifty times a night. Clips on in seconds and lives in my jacket pocket. Cheap insurance really. Two of the other guys at the depot have bought one since they saw mine.

"Bought this after a buddy lost his bike to an angle grinder gang. Was skeptical, thought it'd be flimsy for the money, but it's a seriously solid piece of kit. Weighs a fair bit in the hand which is exactly what you want. Rains constantly up here and it hasn't rusted or played up once."

🛡️ Description
The DiscGuard: Thieves Hate It. You'll Sleep Easy.
Your bike is a target. The DiscGuard makes sure it's not your bike they take.
🔊 The 110dB Scream That Ends Theft Instantly The second a thief touches your bike, a 110dB alarm rips through the street — loud enough to turn every head and send them running empty-handed. Most thieves bolt before they even get their tools out.
⚡ On in 2 Seconds. Off in 1. Clamp it onto your brake disc, press down, done — alarm armed instantly, no tools, no fuss. A quick turn of the key and you're gone. Security that never slows you down.
🛡️ Built to Take a Beating Hardened alloy body shrugs off hammers, prying and brute force. They can hit it all they like — it won't budge, and it won't shut up.
🔋 Charge It Once, Forget It for Months A single USB-C top-up (about 70 mins) lasts 5–6 months. No fiddly batteries, no nasty surprises. IP-rated and weatherproof, rain or shine.
Fits virtually every motorcycle and scooter. Slips straight into your pocket. Backed by 10,000+ riders who ride knowing their bike will still be there when they get back.
🔒 What's In The Box
Everything You Need. Straight Out of the Box.
🔒 1× DiscGuard Alarm Disc Lock The star of the show. 110dB alarm, hardened alloy body, ready to armour up your brake disc in seconds.
🔑 2× Security Keys One for you, one for backup (or your partner in crime-fighting). Never get caught out with a lost key.
🟢 1× Hi-Vis Reminder Cable (FREE for Bundle orders) Loops from your lock to your handlebar so you never ride off with the lock still on. Saves your disc — and your dignity.
⚡ 1× USB-C Charging Cable Top up in ~70 minutes, ride protected for 5–6 months. Plug in, power up, forget about it.
All neatly packed, all included, all ready to go. Unbox it, clip it on, and let the DiscGuard do the worrying for you.
🔧 How To Use
Locked & Loaded in Under 10 Seconds
No manual needed. No tools. If you can clip a keyring, you can use the DiscGuard.
1️⃣ Clamp It On Slot the DiscGuard onto your brake disc, lining the pin up with one of the holes. Push it firmly until it clicks shut.
2️⃣ Press to Arm Press down to lock — the alarm arms itself instantly. That's it. Your bike is now guarded 24/7 and the lock can't be removed without the key.
3️⃣ Attach the Hi-Vis Reminder Loop the bright cable from the lock to your handlebar. A simple reminder that saves you from riding off with it still on.
4️⃣ Ride Off Worry-Free When you're back, just insert your key, turn, and lift it off. Disarmed and pocketed in one second flat.
💡 Pro Tip: Fit it to the front disc where it's most visible — the brighter and more obvious your lock, the faster a thief moves on to an easier target.

⚠️ WARNING: BEWARE OF CHEAP FAKES
The authentic DiscGuard is exclusively sold here. Knockoffs found on Amazon or TikTok are unreliable counterfeits that can fail when you need them most. Only our genuine lock uses a real hardened alloy body and a true 110dB alarm to guarantee your bike's security.
YOUR BIKE WILL BE STOLEN. IT'S JUST A MATTER OF WHEN.
EVERY 12 MINUTES. ANOTHER BIKE GONE.
Over 44,000 motorcycles are stolen in the US every year. Angle grinders. Van lifts. Two thieves and 20 seconds — and your bike is gone before you've finished your coffee.
THIEVES GO FOR THE EASY TARGET.
An unprotected bike is a free bike. Thieves scan the street for the one with no lock, no alarm, no fight. Make yours the one that screams back, and they'll move on.
6 IN 10 STOLEN BIKES ARE NEVER SEEN AGAIN.
Only around 4 in 10 stolen bikes are ever recovered. No bike back, no closure — just a claim, a rejected excess, and premiums that climb every renewal.
ARMED IN SECONDS. LOUD IN AN INSTANT.
Clamp it on your brake disc, press down, done — armed in under 10 seconds.
The moment a thief touches your bike, a 120dB alarm screams the whole street awake. They panic, they run, they leave empty-handed. While your neighbour's filling in insurance claims, you're sleeping soundly.
BUILT TO SURVIVE US STREETS.
Hardened alloy body that laughs off every attack we threw at it—hammers, pry bars, brute force. All failed.
Anti-corrosion sealed to shrug off harsh American winters, and a blinding 120dB alarm that turns any tamper attempt into a public scene. Compact enough to pocket, loud and tough enough to ruin a thief's night.
Ear-splitting 120dB alarm scares thieves off
Hi-vis body thieves spot & avoid from across the street
USB-C rechargeable — 5-6 months per charge
Small enough to pocket, tough enough to protect

YOUR 7 BIGGEST CONCERNS ANSWERED
Will this fit my motorcycle or scooter?
Yes, the DiscGuard fits virtually every motorcycle and scooter on US roads, from 125cc commuters to full-blown superbikes. The locking pin is sized to fit the standard holes on almost any brake disc. It takes 10 seconds to check: if your brake disc has holes (nearly all do), you're sorted. Still unsure? Email support@trydespi.com with your bike model and we'll confirm for you.
How quickly can I get it on and off?
Armed in under 10 seconds, off in one. No complicated setup, no instruction manual needed. Clamp it onto your brake disc, press down to lock, and the alarm arms itself instantly. A quick turn of the key and you're gone. Simple enough to use every single time you park, but tough enough to stop thieves in their tracks.
Can thieves actually break through this?
The DiscGuard's hardened alloy body is engineered to resist hammers, pry bars and brute force. But its real weapon is the noise: the moment anyone touches your bike, a 120dB alarm screams the whole street awake. No security is 100% invincible, but here's the reality of US bike crime — thieves want quiet, easy targets. A lock that's impossible to break silently and screams the second they try? They move straight on to the next bike. It's your first and loudest line of defence.
Won't the alarm go off by accident?
No. The DiscGuard uses a smart shock sensor: light vibration triggers 3 short warning beeps first, so a passing truck or a nudge won't set off the full siren. Only genuine tampering escalates it to the full 120dB alarm for 15 seconds. Clever enough to know the difference between the wind and a thief.
How long does the battery last?
Charge it once with the included USB-C cable (about 70 minutes) and it runs for 5–6 months on a single charge. No fiddly batteries to hunt down or replace. A low-battery indicator gives you plenty of warning before it needs a top-up — plug it in overnight and forget about it.
What if I lose the keys?
You get 2 keys with every order — keep one on your keyring and one somewhere safe at home. Lost them both? Like any high-security device, you'd need a locksmith. But honestly, most riders are very careful with the keys that protect a bike worth thousands.
What if it doesn't work for my setup?
Zero risk to try it. Our 90-Day Peace of Mind Guarantee means you can test it properly on your own bike. Doesn't fit? Changed your mind? Email support@trydespi.com and we'll process your full refund, no interrogation. But honestly? Most riders don't send them back — they usually come back to buy a second one for their partner's bike.

Living in Chicago, you're basically asking for it without proper security. Saw two guys on my Ring doorbell at 3am eyeing up the bikes on my street. The second one gave mine a nudge, the DiscGuard went off like a car alarm on steroids, 3am and the whole street lit up. They properly legged it and didn't come back. Best investment I've made all year.

"After my buddy's MT-07 got stolen off his driveway last week (two guys, angle grinder, gone in under a minute), I wasn't taking any chances. Ordered this straight away. Takes literally 10 seconds to pop on and the alarm arms itself. I actually sleep soundly now knowing that if anyone so much as touches it, the whole street's going to hear about it. If you park your bike outside, you need this.

Our neighborhood group chat has been crazy lately with all the bike thefts around here, feels like every week someone's had theirs stolen. Bought a DiscGuard and honestly, half the guys on the street have followed suit now. The road next to us got hit again last night, but ours were all untouched. Thieves want an easy ride, don't give them one!

Fits my Yamaha MT-03 perfectly, slots right onto the disc no problem. And it's loud, tested it in the garage and it really screams. Happy with it.

Decent piece of gear for the money. Alarm's loud and the build feels sturdy. Only knocked a star off because the instructions were a bit brief, but figured it out fine

Fits my MT-07 like it was made for it. No wobble, clamps on tight. Really happy with it to be honest.

Ordered it, turned up quick, fits my CB500X no problem at all. Alarm's seriously loud and it's small enough to actually carry around. Can't complain.

Been using it a couple months now on my GS. Fits perfectly, still on the first charge, and it's survived a fair bit of rain already. Solid product.

Good lock. Fits my Ninja 650 nicely and the alarm's no joke. Would've liked it in a couple more colors but that's just me being picky. Does the job well.

Fits my bike perfectly and it's dead easy to get on and off. That was my main worry ordering online but no issues at all. Quality's better than I expected.

Honestly a well thought out bit of gear, alarm's loud enough to wake the street, and it's small enough that I actually take it with me. That was always my problem before.

Does what it says. Fits my Bonneville nicely, feels well built, and the free lanyard's a handy touch so you don't ride off with it on. Solid buy.
