The Complete Guide to Motorcycle Covers, Locks, and Security

Why Motorcycle Security Matters

Motorcycles are disproportionately targeted by thieves. They are lighter and easier to move than cars — a motorcycle can be lifted into a van in seconds by two people. Many motorcycles have high resale value relative to their size, and stolen motorcycles can be stripped for parts quickly.

The consequences of motorcycle theft go beyond the financial loss. Insurance premiums increase. Replacement takes time. If the motorcycle is recovered, it is often damaged. For many riders, the motorcycle represents a significant investment and a deeply personal possession.

Effective security does not guarantee that a motorcycle will not be stolen — a determined, equipped thief can defeat most locks given enough time and tools. But effective security deters the majority of opportunistic thieves and delays even determined ones — increasing the risk and effort required, making the motorcycle a less attractive target than a less-protected one nearby.

Layered Security — The Principle

No single lock or device provides complete protection. The most effective approach is layered security — multiple, different security measures used together. Each layer adds time, effort, tools, and risk for the thief:

Layer 1: Steering lock — The built-in steering lock that every motorcycle has. Minimal deterrent on its own but adds a layer.

Layer 2: A physical lock — A disc lock, chain, or U-lock that prevents the motorcycle from being wheeled away.

Layer 3: Anchoring — A chain or lock that secures the motorcycle to an immovable object (a ground anchor, a lamp post, a railing). This prevents the motorcycle from being lifted into a van.

Layer 4: Alarm or tracker — An electronic deterrent (alarm that sounds when the motorcycle is disturbed) or a recovery tool (GPS tracker that allows the motorcycle to be located if stolen).

Layer 5: Cover — A motorcycle cover conceals the make, model, and value of the motorcycle from passing thieves. Out of sight is the simplest form of deterrent.

Each layer individually is defeatable. Together, they create a cumulative deterrent that makes the motorcycle significantly harder, slower, and riskier to steal.

Disc Locks

A disc lock is a compact, heavy lock that clamps directly onto the motorcycle's brake disc — preventing the wheel from rotating. The disc cannot spin past the lock, so the motorcycle cannot be wheeled away.

Strengths

Compact and portable. A disc lock is small enough to carry in a jacket pocket or under the seat. It is the most convenient lock to carry and use on every ride.

Quick to fit. Clamp onto the disc, engage the lock. Takes seconds.

Visible deterrent. A bright, visible disc lock signals that the motorcycle is secured.

Limitations

Does not anchor the motorcycle. A disc lock prevents the motorcycle from being wheeled away — but it does not prevent the motorcycle from being lifted into a van. Two people can lift a disc-locked motorcycle.

Risk of riding away with the lock fitted. Forgetting to remove the disc lock before riding is a common and potentially expensive mistake — the lock jams against the caliper, damaging the disc, caliper, and lock. A disc lock reminder cable (a bright cable that connects the lock to the handlebar) is an essential companion to any disc lock.

Disc Locks with Alarms

Some disc locks include a built-in motion-sensing alarm that sounds a loud siren if the motorcycle is moved or disturbed. These combine two security layers (physical lock and alarm) in a single device — a practical and popular option.

Chain Locks

A chain lock is a heavy-duty chain (hardened steel links) with a padlock or integrated lock. The chain is passed through the motorcycle's frame or wheel and around an immovable object — anchoring the motorcycle in place.

Strengths

Anchoring capability. A chain is the primary tool for securing a motorcycle to a fixed object — a ground anchor, a lamp post, a permanent railing, or another heavy, immovable structure.

Flexibility. The chain can be looped through various parts of the motorcycle and around objects of different sizes and shapes.

High security (quality chains). A quality hardened-steel chain with a high-security padlock is extremely difficult to cut — requiring power tools, significant time, and creating noise that attracts attention.

Limitations

Heavy. A quality security chain is very heavy — typically 3–8 kg or more depending on length and grade. Carrying a heavy chain on the motorcycle is impractical for many riders. Chains are most practical as a fixed security measure at home, at the workplace, or at regular parking locations.

Length matters. A longer chain provides more flexibility for reaching anchor points — but adds more weight. A shorter chain is lighter but may not reach a suitable anchor.

What to Look For

Chain grade. Hardened, case-hardened, or manganese steel chains resist cutting by bolt croppers and angle grinders. Cheap, unhardened chain can be cut through with basic tools in seconds. The chain grade is the most important factor — a weak chain provides a false sense of security.

Lock quality. The lock (padlock or integrated) must match the chain's security level. A high-grade chain with a cheap padlock is only as secure as the padlock.

U-Locks (D-Locks)

A U-lock (also called a D-lock) is a rigid, U-shaped hardened steel shackle that locks around the wheel and/or frame, and optionally around an immovable object.

Strengths

Very difficult to cut. The rigid shackle is harder to attack with bolt croppers than a chain (bolt croppers need to bite around the material — the rigid, narrow U-shape limits the angle of attack). Cutting a quality U-lock typically requires a power tool.

Compact. Lighter and more compact than a heavy chain. Some models include a frame mount for carrying on the motorcycle.

Limitations

Rigid shape limits flexibility. The fixed shape of the U-lock means it can only secure what fits within the U — if the anchor point is large or awkwardly positioned, the shackle may not reach.

Smaller locking area than a chain. The U-shape accommodates less bulk than a chain loop — it may not fit around both the wheel and a thick anchor point.

Ground Anchors

A ground anchor is a heavy, hardened steel anchor point permanently fixed to the floor of a garage, shed, or parking area. The motorcycle's chain or U-lock is looped through the anchor, securing the motorcycle to the ground.

Why It Matters

Without an anchor, a chain secures the motorcycle to itself — which does not prevent the motorcycle from being lifted or carried away. An anchor provides the immovable attachment point that makes the chain effective.

Types

Bolt-down anchors — Bolted into a concrete floor using security bolts (typically requiring a special tool to remove). The most common domestic option.

Cast-in anchors — Set into fresh concrete when the floor is laid. The most secure option — the anchor cannot be unbolted.

Installation

Ground anchors require a solid concrete floor (minimum 100 mm thickness for bolt-down anchors). Installation involves drilling into the concrete, inserting the anchor, and securing with the provided fixings. The fixings should be tamper-resistant (requiring a unique or specialist tool to remove).

Security Ratings — Sold Secure and Thatcham

Independent security ratings provide objective assessments of lock and security product quality:

Sold Secure

A UK-based independent testing organisation that rates security products at three levels:

Bronze — Resists attack from basic tools for a defined time period. A minimum level of deterrent.

Silver — Resists attack from more advanced tools for a longer period. A good level of security.

Gold — Resists the most sustained and aggressive attacks. The highest Sold Secure rating. Recommended for high-value motorcycles and high-theft-risk areas.

Thatcham

The motor insurers' research centre that rates vehicle security products. Thatcham-approved products may qualify for insurance discounts.

Check whether your insurer requires or recommends a specific security rating — some insurance policies specify a minimum Sold Secure or Thatcham rating for the lock used.

Steering Locks and Ignition Security

Every motorcycle has a built-in steering lock — a mechanism that locks the handlebars at full turn, preventing the motorcycle from being steered in a straight line. The steering lock is engaged by turning the ignition key to the lock position.

The steering lock is a basic deterrent — it does not prevent the motorcycle from being wheeled (by lifting the front or forcing the lock) and is relatively easy to break with force. It should always be engaged, but it should never be relied upon as the sole security measure.

GPS Trackers

A GPS tracker is an electronic device hidden on the motorcycle that transmits the motorcycle's location in real time (or at intervals) to a smartphone app or monitoring service.

What It Does

If the motorcycle is stolen, the tracker allows the owner (and/or the police) to locate the motorcycle — often leading to recovery. A tracker does not prevent theft — it aids recovery after theft.

Types

Self-monitored trackers — Transmit location data directly to the owner's smartphone via a mobile app. The owner monitors the motorcycle's location and sets up movement alerts (notifications if the motorcycle moves when it should not). Typically require a SIM card and a data subscription.

Professionally monitored trackers — Transmit to a monitoring centre that alerts the owner and, in some cases, contacts the police on the owner's behalf. Higher-end services include 24/7 monitoring. Require a subscription.

The Practical Value

A GPS tracker significantly increases the chance of recovering a stolen motorcycle — particularly if the theft is detected quickly (through a movement alert) and the tracker's location is shared with the police promptly.

Hide the tracker securely. If the thief finds and removes the tracker, it provides no benefit. Concealment in a location that is not obvious — behind panels, inside bodywork, or within an accessory — is important.

Alarms and Immobilisers

Alarms

A motorcycle alarm sounds a loud siren when it detects motion, vibration, or tilt. The noise attracts attention and may deter the thief from continuing.

Stand-alone alarms — Small, battery-powered units attached to the motorcycle. Some are integrated into disc locks.

Integrated alarms — Wired into the motorcycle's electrical system. More sophisticated — typically include a remote-control fob, sensitivity adjustment, and sometimes GPS tracking.

Immobilisers

An immobiliser prevents the motorcycle's engine from starting without the correct key, fob, or transponder. Most modern motorcycles include a factory-fitted immobiliser. Aftermarket immobilisers add an additional layer of electronic security.

Motorcycle Covers — Weather Protection

A motorcycle cover protects the motorcycle from rain, UV light, dust, bird droppings, tree sap, frost, and general environmental degradation when parked outdoors or in an open garage.

Why It Matters

A motorcycle exposed to the elements degrades faster than one that is covered. Rain corrodes exposed metal surfaces. UV light fades paint and degrades rubber and plastic components. Bird droppings etch through paint and chrome. Frost and condensation promote corrosion, particularly on chains, brake components, and electrical connections.

A cover also provides visual concealment — a covered motorcycle does not advertise its make, model, or value to passing thieves.

Choosing the Right Cover

Outdoor Covers

Must be waterproof (or at least highly water-resistant), UV-resistant (to withstand prolonged sun exposure without degrading), and breathable (to allow moisture trapped beneath the cover to escape — a non-breathable cover traps condensation against the motorcycle, which causes corrosion).

Heat-resistant lining — If the cover will be fitted while the engine and exhaust are still warm, a heat-resistant inner panel prevents the cover from melting against the exhaust.

Secure fit — Elasticated hems, buckle straps, or drawstrings that hold the cover in place in wind. A loose cover that blows off provides no protection and adds litter to the street.

Lock hole — Some covers include a grommet or reinforced hole that allows a chain or lock to pass through the cover and through the motorcycle — securing both the cover and the motorcycle simultaneously.

Indoor Covers

Indoor covers provide dust protection and prevent accidental scratches (from items stored nearby or from people brushing against the motorcycle). They do not need to be waterproof or UV-resistant but should be soft (to avoid scratching paint and chrome) and breathable.

Size

Covers are sold by motorcycle size category — small (scooters, 125cc), medium (standard motorcycles, 250–600cc), large (sports, touring, 600cc+), and extra-large (full-size touring with panniers). Choose a cover that fits the motorcycle without being so loose that it flaps or so tight that it pulls against mirrors and windscreens.

Combining Security Measures

A practical home security setup:

Disc lock (carried on every ride) + heavy chain through frame to ground anchor (at home) + motorcycle cover + steering lock engaged = four layers of security.

A practical away-from-home setup:

Disc lock with alarm (carried in pocket or under seat) + disc lock reminder cable + steering lock engaged = portable security that provides physical lock, audible alarm, and basic anti-theft in a pocket-sized package.

Adding a GPS tracker to either setup provides a recovery layer in the event that the physical security is defeated.

Common Mistakes and How to Avoid Them

Relying on the steering lock alone. The steering lock is the absolute minimum. It does not prevent the motorcycle from being lifted or the lock being forced. Always use an additional physical lock.

Using a cheap, unhardened chain. A cheap chain can be cut in seconds with basic bolt croppers. Invest in a rated, hardened chain — the chain grade determines the security level.

Not anchoring the chain to an immovable object. A chain looped through the motorcycle but not attached to anything fixed does not prevent the motorcycle from being lifted into a van.

Forgetting to remove the disc lock. Use a reminder cable — every time, without exception.

Leaving the motorcycle uncovered outdoors. A cover protects from weather damage and conceals the motorcycle from opportunistic thieves. It takes 30 seconds to fit.

Not checking insurance requirements. Some insurers require specific security measures (rated locks, approved trackers) as a condition of the policy. Check your policy and comply.
