Oxford Boss 16mm Heavy Duty 100 Decibel Alarm Motorcycle Disc Lock & Chain

The 16mm Boss Alarm Padlock is Oxford's strongest ever lock with an integral alarm. The padlock has a 16mm shackle and an ear-splittingly loud 100bB alarm which is triggered by movement sensors (the padlock can also be engaged without setting the alarm). The 16mm shackle can be used as either a padlock or disk lock, and is vibration-resistant and weather-proof against water, frost and heat. 

The Oxford Boss Alarm Chain Lock has been independently tested and approved by Sold Secure and has been awarded Motorcycle GOLD standard, SBSC and ART 4*. Insurance discounts are available in the UK when you use this lock.

The Big Boss Alarm lock has a key replacement service so that if you are unfortunate enough to lose all your keys a new one can be made up. Just remember to take note of your key number and keep this in a safe place.

Also available in a slightly smaller 14mm Boss version.

Available with or without matching Oxford Boss 12mm chain in 1.2 metre, 1.5 metre or 2.0 metre lengths.
