Best Motorcycle Locks (Tested & Ranked for 2026)

The best motorcycle lock overall is the Kryptonite New York Fahgettaboudit Chain 1415 -- 14mm hardened manganese steel links with a disc lock cylinder that resists bolt cutters, angle grinders, and pry attacks. For a portable everyday lock, the ABUS Granit Detecto SmartX 8078 disc lock adds a 100 dB alarm and Bluetooth smartphone control. Budget riders should grab the Kryptonite Keeper 585 Chain Lock for under $50 -- it won't stop a determined crew, but it stops the vast majority of opportunistic theft.

A motorcycle is stolen every 11 minutes in the US. According to the National Insurance Crime Bureau (NICB), over 46,000 bikes disappear every year, and the recovery rate is roughly 30%. Most stolen motorcycles are stripped for parts within hours. Your steering lock is not security -- it's a suggestion. A screwdriver defeats it in seconds.

The right lock doesn't make your bike unstealable. Nothing does. But it makes your bike harder and slower to steal than the one parked next to it. Thieves are opportunistic. They want speed and silence. Every obstacle you add -- a disc lock, a chain, an alarm -- buys time they can't afford to spend. That's the game.

Our Top Picks:

How We Evaluated These Locks

We assessed every lock across five criteria that actually matter for motorcycle security:

Security rating -- Sold Secure, ART, and Thatcham ratings exist for a reason. These independent organizations test locks against real attack methods (bolt cutters, angle grinders, picks, pry attacks) and assign a rating. Gold or Diamond ratings mean the lock survived serious, timed assault.

Attack resistance -- What specific tools does it take to defeat this lock? A 5mm chain falls to bolt cutters in seconds. A 14mm hardened chain requires an angle grinder and several minutes of loud, sparky, conspicuous cutting. Bigger matters.

Portability -- The best lock in the world is useless if you leave it at home. A 15-pound chain isn't going on your daily commute. A disc lock fits in your jacket pocket. You need security you'll actually carry.

Alarm capability -- Built-in motion sensors and alarms add a layer of protection that turns a silent theft into a public event. Not all alarms are created equal -- some trigger from a breeze, others require deliberate movement.

Value -- A $30 disc lock and a $200 chain serve different riders. We matched each lock to the rider it's best for, not just the rider with the biggest budget.

Best Motorcycle Chain Locks

Chain locks are the strongest physical deterrent you can put on a motorcycle. A heavy chain through the frame, locked to a fixed anchor, prevents your bike from being rolled, lifted, or loaded into a van. The trade-off is weight -- the best chains are heavy. But at home, where over 50% of motorcycle thefts occur, weight doesn't matter.

1. Kryptonite New York Fahgettaboudit Chain 1415 -- Best Chain Lock

The Fahgettaboudit is named after a New York attitude for a reason -- this chain was designed for one of the highest-theft cities in the world. The 14mm links are made from hardened manganese steel, a material specifically chosen because it resists cutting, sawing, and hammering. Bolt cutters can't get through it. Period. An angle grinder can, but it takes time, creates noise and sparks, and draws exactly the kind of attention thieves avoid.

The included New York disc lock cylinder uses a double-deadbolt anti-rotation design with a pick-resistant keyway. The lock body itself is hardened and drill-resistant. Kryptonite rates it 10/10 on their own security scale, and Sold Secure gives it Diamond -- the highest possible rating.

The catch? It weighs about 15 pounds in the 3.25-foot length. You're not carrying this in your backpack on a daily commute. This is a home security chain -- thread it through your frame (not the wheel, wheels are removable), lock it to a ground anchor bolted into your garage floor or a fixed post, and sleep well.

Strengths

• 14mm hardened manganese steel defeats bolt cutters
• Sold Secure Diamond -- highest independent security rating
• Pick-resistant disc lock cylinder with double deadbolt
• 5-year warranty with anti-theft protection offer
• The benchmark that other chains are measured against

Weaknesses

• 15 lbs -- too heavy for daily carry
• 3.25 ft length limits anchoring options (longer versions available but heavier)
• ~$130 price point is premium
• Requires a separate ground anchor for maximum effectiveness

Who it's for: Any rider who parks at home and wants the best physical security money can buy. Also excellent for workplace parking if you can leave it locked to a fixed object.

2. Oxford Monster Chain Lock -- Best Mid-Range Chain

The Oxford Monster sits in the sweet spot between budget chains and the Fahgettaboudit. The 12mm square-profile links are the key feature -- square links are harder for bolt cutters to grip than round links, giving this chain better cut resistance than you'd expect from the 12mm spec. The included padlock is double-locking with a hardened steel shackle.

At $80-100, it's significantly cheaper than the Kryptonite Fahgettaboudit while still earning a Sold Secure Gold rating. The 1.2m (about 4 feet) length gives you enough reach to thread through the frame and around a post or ground anchor.

The trade-off is straightforward: it's not as heavy-duty as the Fahgettaboudit's 14mm links. A determined attacker with an angle grinder will get through it faster. But for the price, it's excellent security -- and far, far better than no chain at all.

Who it's for: Riders who want serious chain security without spending $130+. Great for apartment complexes where you can chain to a railing or post.

3. Kryptonite Keeper 585 Chain Lock -- Best Budget Chain

Let's be honest about the Keeper 585: it's a deterrent, not a fortress. The 5mm links can be defeated by large bolt cutters. An angle grinder goes through them quickly. This is not the chain you use to protect a $15,000 bike parked on a city street overnight.

But here's what it does do: it stops opportunistic theft cold. A thief walking through a parking lot looking for an easy score sees a chain and moves on. They're not carrying bolt cutters. They're looking for bikes with nothing but a steering lock. The Keeper 585 makes you the harder target.

The integrated lock cylinder is a nice touch -- the lock is built into the chain, so there's no separate padlock to carry, lose, or have picked independently. The 2.7-foot length is enough to loop through a wheel and around a post, though threading through the frame is always better.

At under $50, it's cheap enough that every rider should own one. Keep it in your top case or under your seat for those times you need to lock up somewhere you didn't plan to be.

Who it's for: Budget-conscious riders, new riders buying their first security, or anyone who needs a lightweight chain they'll actually carry.

Best Motorcycle Disc Locks

Disc locks are the everyday carry of motorcycle security. They clamp onto your brake rotor, preventing the wheel from spinning. Small enough to fit in a jacket pocket, fast to apply, and effective at stopping ride-away theft. Every rider should own one.

The limitation: a disc lock doesn't prevent lifting. Two people can pick up your bike and put it in a van with the disc lock still on. That's why disc locks work best as Layer 1 in a layered security approach -- the visible deterrent that says "this bike isn't unprotected."

4. ABUS Granit Detecto SmartX 8078 -- Best Smart Disc Lock

The SmartX 8078 is what happens when German engineering meets motorcycle security. There's no keyhole -- you unlock it with your phone via Bluetooth. No key to lose, no cylinder to pick. The ABUS app lets you share access with other riders, check lock status remotely, and view an alarm history log.

The 3D tilt sensor is smarter than basic vibration alarms. Instead of triggering when a truck drives by, it detects actual movement of the bike -- tilting, lifting, or rolling. False alarms are minimal compared to cheaper vibration-based systems. When it does trigger, the 100 dB alarm is loud enough to make everyone within 50 meters stop and look.

ABUS rates it Security Level 18 out of 20 -- one of the highest-rated disc locks in production. The lock body is hardened special steel, and the 13mm bolt is massive for a disc lock. It fits most motorcycle brake rotors, though you should verify clearance on your specific bike before buying.

The price -- around $150 -- is steep for a disc lock. But you're getting physical security, an alarm system, and smart lock technology in one package. For riders who want the best single-device solution, this is it.

Strengths

• Keyless Bluetooth unlock -- no keys to lose or keyholes to pick
• 3D tilt sensor dramatically reduces false alarms
• 100 dB alarm is genuinely loud and attention-grabbing
• ABUS Security Level 18/20 -- near-maximum security rating
• App features: shared access, lock status, alarm log

Weaknesses

• ~$150 is expensive for a disc lock
• Requires smartphone to unlock (dead phone = locked out without backup)
• Battery replacement requires a specific ABUS tool
• Heavier than basic disc locks at ~1.5 lbs
• App can be finicky with Bluetooth connection on some phones

5. Xena XX6 Disc Lock Alarm -- Best Disc Lock Under $75

The Xena XX6 has been a rider favorite for years, and for good reason: it's a dead-simple alarm disc lock that works every time. Lock it on your rotor. Walk away. It arms itself automatically in about 15 seconds. If anyone touches, bumps, or moves your bike, a 120 dB alarm screams until the movement stops.

There's no app, no Bluetooth, no smartphone dependency. Just a lock, a sensor, and a very loud alarm. The CR2 lithium battery lasts several months with normal use and takes 10 seconds to replace. The stainless steel body resists corrosion and looks sharp even after years of use.

The 6mm locking pin fits most motorcycle brake rotors. It's compact enough to carry in your jacket pocket or tank bag. At under $75, it gives you both physical locking and an alarm system -- two security layers in one affordable package.

The downside? The alarm can false-trigger. Heavy wind, a nearby car door slamming, or a truck rolling past can set it off. It's not as smart as the ABUS 3D tilt sensor. But honestly? A few false alarms are better than no alarm at all. Thieves don't know it's a false alarm.

Who it's for: Riders who want alarm protection without paying $150+ for the ABUS. The best value alarm disc lock on the market.

6. Kryptonite Evolution Disc Lock -- Best Basic Disc Lock

Not every rider wants or needs an alarm. If you want a straightforward, well-built disc lock that does one job extremely well -- preventing your wheel from spinning -- the Evolution Compact is it.

The 13mm hardened steel shackle is thicker than most disc lock pins, giving it genuine resistance to cutting and prying. The flat-top plate design sits flush against the rotor, minimizing the profile and making it harder for a thief to get a tool on it. Sold Secure Gold and ART 4-star ratings confirm it stands up to real attack testing.

It includes a reminder cable (the bright orange cord that loops to your handlebar) and three stainless steel keys. The lock cylinder is pick-resistant and drill-protected. At under $50, it's one of the most affordable Sold Secure Gold disc locks available.

Who it's for: Riders who want proven physical security without electronics. Great as a backup disc lock to pair with a chain at home, or as your primary carry lock for daily stops.

Disc Lock vs Chain Lock: Which Do You Need?

This isn't an either/or decision. Disc locks and chain locks serve different purposes, and the best security uses both.

The ideal setup: A disc lock that goes on every time you park (even for 5 minutes at a gas station), plus a heavy chain locked to a ground anchor at home. The disc lock handles your daily security needs. The chain handles overnight and long-term parking where your bike is most vulnerable.

If you can only afford one right now, start with a disc lock. It's the security you'll actually carry and use consistently. Add a chain when budget allows.

Ground Anchors and GPS Trackers: Completing Your Security

A chain is only as strong as what it's attached to. Wrapping your Fahgettaboudit around a wooden fence post gives a thief a 30-second shortcut -- they cut the post, not the chain.

Ground Anchors

A ground anchor is a hardened steel bracket bolted or cemented into your garage floor, driveway, or parking area. You thread your chain through it, creating a fixed connection between your bike and the earth. Good ground anchors use tamper-proof bolts that can't be removed with standard tools.

The Kryptonite Stronghold Anchor and Oxford Anchor Force are both Sold Secure Diamond rated and designed for concrete installation. Budget around $40-60 for the anchor itself, plus installation (four concrete anchors and a masonry drill bit).

If you rent and can't drill into concrete, look for portable ground anchors with heavy base plates, or chain to existing fixed structures -- steel posts, metal railings, or embedded fixtures. The goal is an anchor point that takes more time to defeat than the chain itself.

GPS Trackers

If a thief defeats your locks, a GPS tracker is your recovery tool. Hidden trackers like the Monimoto or Apple AirTag (tucked under your seat or inside a fairing) let you track your bike's location in real-time after it's taken.

GPS trackers don't prevent theft -- they help you get the bike back (or help police get it back). The recovery rate for tracked motorcycles is dramatically higher than for untracked ones. A $100 tracker can save a $10,000 bike.

How to Use Motorcycle Locks Effectively

Even the best lock fails if you use it wrong. Here are the rules:

Lock to fixed, immovable objects. Signposts, fence posts, and lightweight bike racks are not security. They can be cut, unbolted, or lifted over. Use thick steel posts embedded in concrete, structural columns, or dedicated ground anchors.

Lock through the frame, not the wheel. Wheels unbolt. Frames don't. A chain through your wheel only costs the thief the time to remove two axle bolts. A chain through the frame means they need to cut the chain or cut your frame -- both require real tools and real time.

Lock high, not low. A chain lying on the ground gives a thief leverage and a surface to brace tools against. Keep the chain off the ground so they can't use the pavement as an anvil while swinging a hammer at your lock. This also makes bolt cutters harder to position.

Use the disc lock on the front rotor. The front wheel is harder to defeat than the rear because the forks and steering geometry make it nearly impossible to roll with a locked front rotor. A locked rear rotor can sometimes be dragged if a thief lifts the rear end.

Lock every time you park. Not "when you feel like it." Not "only at night." Every. Time. Theft happens in broad daylight in busy parking lots. The five seconds a disc lock takes is always worth it.

Layer your security. One lock is a barrier. Two locks are a serious time problem. A disc lock AND a chain AND an alarm turn a 30-second theft into a 5-minute public spectacle. Most thieves walk away from that.

Where Motorcycle Theft Happens

Understanding where bikes get stolen helps you prioritize your security spending:

At home -- 50%+ of thefts. Your driveway, apartment parking lot, or garage (if it's accessible). This is where heavy chains and ground anchors pay for themselves. Invest the most security here because your bike spends the most time here.

Public parking -- 25-30% of thefts. Shopping centers, restaurants, downtown streets. A disc lock is your primary defense here since you can't carry a 15-pound chain everywhere.

Work/school -- 15-20% of thefts. If you commute by motorcycle, your bike sits in the same spot for 8+ hours every day. Thieves notice patterns. A disc lock plus a lighter chain (like the Keeper 585) is a solid combo for regular workplace parking.

How Much to Spend on Motorcycle Security

A reasonable security budget is 5-10% of your bike's value. A $5,000 bike justifies $250-500 in security. A $15,000 bike justifies more. Here's how to allocate:

Budget setup ($75-100): Kryptonite Keeper 585 chain ($45) + Kryptonite Evolution disc lock ($50). Two layers of security for under $100. This handles the majority of theft scenarios.

Mid-range setup ($150-200): Oxford Monster chain ($90) + Xena XX6 alarm disc lock ($65). Stronger chain, alarm capability, three security layers.

Premium setup ($300+): Kryptonite Fahgettaboudit chain ($130) + ABUS SmartX 8078 ($150) + ground anchor ($50) + GPS tracker ($100). Four to five security layers. This is the setup for high-value bikes, high-theft areas, or riders who simply refuse to be a victim.

No matter what you spend, comprehensive motorcycle insurance with theft coverage is the final safety net. Even the best locks can be defeated given enough time and tools. Insurance ensures you're not financially destroyed if the worst happens.

Lock Maintenance

Locks live outdoors, get rained on, and collect road grime. A seized lock is as useless as no lock at all.

Lubricate the keyway every few months with graphite lubricant (not WD-40 -- it attracts dust). A few squirts keep the cylinder turning smoothly and prevent internal corrosion.

Keep chains clean. Wipe down your chain with a rag after wet rides. Road salt, in particular, accelerates corrosion on even hardened steel. A light coat of chain lube or anti-corrosion spray extends the life significantly.

Replace batteries in alarm locks. The Xena XX6 uses a CR2 battery; the ABUS SmartX has a rechargeable internal battery. When your alarm starts chirping weakly instead of screaming, it's time. Carry a spare battery in your tool kit.

Inspect for damage. After a tip-over or impact, check your disc lock pin for bending and your chain links for deformation. A damaged lock may not close properly or may be significantly weakened.

Frequently Asked Questions

What is the best type of motorcycle lock?

A heavy chain lock (12mm+ hardened steel) anchored to a ground bolt is the most secure single lock type. But the best overall approach combines a chain lock at home with a portable disc lock for daily stops. No single lock type covers every scenario -- layered security with multiple lock types is always stronger than relying on one.

Are disc locks worth it for motorcycles?

Yes. A disc lock is the minimum security every rider should carry. It prevents ride-away theft, takes 5 seconds to apply, and fits in your pocket. It won't stop a lift-and-load theft (two people picking up your bike into a van), but it eliminates the most common theft method -- someone riding your bike away. At $25-60 for a basic model, it's the cheapest meaningful security you can buy.

Can bolt cutters cut a motorcycle chain lock?

It depends on the chain thickness. Bolt cutters can cut chains up to about 10mm relatively easily. Chains 12mm and above require increasingly large bolt cutters and significantly more force -- a 14mm hardened manganese chain like the Kryptonite Fahgettaboudit is effectively bolt-cutter-proof. An angle grinder can cut any chain, but it requires time, electricity or battery power, and creates noise and sparks that draw attention.

Where should I put a disc lock on my motorcycle?

Always on the front brake rotor. The front wheel is harder to defeat because the fork geometry makes it nearly impossible to roll the bike forward or backward with a locked front rotor. A rear disc lock can sometimes be overcome by lifting the back end and dragging. Thread the locking pin through one of the ventilation holes in the rotor, and always attach the reminder cable to your handlebar so you don't try to ride off with the lock on.

How much should I spend on motorcycle security?

A good rule is 5-10% of your bike's value. A $5,000 bike justifies $250-500 in security (a chain lock, disc lock, and possibly a ground anchor). A budget setup with a Kryptonite Keeper chain and Evolution disc lock runs under $100 and covers most riders. If you park in a high-theft area or own an expensive bike, invest in a premium chain, alarm disc lock, ground anchor, and GPS tracker.

Do motorcycle lock alarms actually deter thieves?

Yes, alarm disc locks are effective deterrents. A 100-120 dB alarm is as loud as a chainsaw or rock concert -- it draws immediate attention from anyone nearby. Most thieves abandon a theft when an alarm triggers because the noise creates witnesses. The alarm won't physically stop them from cutting a lock, but it compresses their time window and increases their risk of being caught or identified.

Should I use a motorcycle cover with my locks?

Absolutely. A motorcycle cover hides your bike's make, model, and value from thieves scoping targets. A thief can't decide if your bike is worth stealing if they can't see it. Thread your chain through the cover's lock hole (most quality covers have one) so the cover can't be easily removed. Combine it with a disc lock underneath for two layers of deterrence before a thief even touches the bike. See our best motorcycle covers guide for recommendations.
