Overview

The Oxford Boss Alarm is one of the best-known premium motorcycle security products available today.

Unlike lightweight travel disc locks, the Boss is designed to provide serious theft protection. Its 14mm hardened steel locking pin fits through the brake disc in the same way as a conventional disc lock, but the body is built like a compact D-lock, making attacks with cutting or leverage tools significantly more difficult.

The addition of a motion-sensitive alarm means it doesn’t just resist theft—it actively draws attention if anyone tampers with your motorcycle.

For many riders, it’s the lock they trust when parking away from home.

Build Quality

Build quality is outstanding.

The lock feels reassuringly solid in the hand, with a hardened steel body finished in Oxford’s distinctive bright yellow coating.

The yellow finish isn’t simply cosmetic.

It makes the lock highly visible, reminding riders to remove it before setting off while also acting as a visual deterrent to potential thieves.

The locking mechanism operates smoothly and feels engineered to withstand years of regular use.

Security Performance

This is where the Boss Alarm really earns its reputation.

Key security features include:

• 14mm hardened steel locking pin
• Motion-sensitive 100dB alarm
• Double locking mechanism
• Weather-resistant construction
• Anti-pick lock design
• Sold Secure Powered Cycle Diamond approval

Few portable motorcycle locks offer this combination of physical strength and audible deterrence.

While no lock can make a motorcycle impossible to steal, the Boss Alarm dramatically increases the time, effort and noise required, making it an excellent first line of defence.

---

Alarm System

The integrated alarm activates automatically when the lock is armed.

If movement is detected, the unit initially issues a warning before sounding its 100dB alarm if interference continues.

The alarm is loud enough to attract attention in most environments without becoming unnecessarily sensitive during normal use.

Battery replacement is straightforward and the electronics are well protected against everyday weather conditions.

---

Everyday Use

Despite its impressive security credentials, the Boss Alarm is surprisingly easy to use.

Simply insert the locking pin through a suitable hole in the brake disc and press the lock closed.

The compact design means it stores more easily than a full-size chain and lock, making it practical for daily commuting as well as touring.

The supplied reminder cable is a welcome addition and helps prevent the embarrassing—and potentially expensive—mistake of attempting to ride away with the lock still fitted.

---

Value for Money

There’s no escaping the fact that the Oxford Boss Alarm is a premium-priced security product.

However, quality motorcycle security is rarely cheap.

Considering the replacement cost of most modern motorcycles, along with rising insurance excesses and the inconvenience of theft, the Boss Alarm represents a sensible investment.

Its combination of robust engineering, recognised security certification and dependable alarm system helps justify the higher purchase price.

Motorhome Monkey Tip

Even the best disc lock is only part of an effective security strategy. Whenever possible, combine your Oxford Boss Alarm with a hardened chain secured to a ground anchor or other immovable object. Layered security takes more time and effort to defeat, making your motorcycle a far less attractive target for thieves.
