Top Block

SRA certified disc lock with 120 dB AVA alarm


French motorcycle security specialist Top Block has added to its anti-theft range with a compact disc lock featuring an integrated alarm - to combine anti-theft performance with active sound-based deterrence. 

Top Block designs and assembles this device at its own facilities in France, so the company can assure its customers that products "meet the highest standards of reliability and resistance - including those required by SRA - the French certification for motorcycle locking systems".

The integrated AVA alarm is said to be capable of emitting a powerful 120 decibel signal upon detection of interference with the bike - its adaptive sequence helps reduce false alarms while maximising deterrence. 

The lock body is made of corrosion-resistant stainless steel and available in polished or textured black paint. The waterproof electronic system is powered by a long-lasting CR2-3V lithium battery (included). To suit a wide range of disc brakes, it comes with two interchangeable locking pins,10 mm and 14 mm, offering excellent resistance to sawing and cutting. 

The ergonomic design ensures easy handling and installation and comes with a soft transport and storage pouch. Equipped with an anti-drill lock featuring multiple key combinations and supplied with two keys, this model fully complies with SRA certification standards. It comes with a 5-year warranty and is available in black or silver.
