DescriptionThe whole story▼
When every ride demands serious chest protection without sacrificing freedom of movement, the Knox Micro-Lock Chest Protector delivers. Engineered around Knox's rate-dependent Micro-Lock technology, this CE Level 1 certified armour stays pliable during normal riding yet stiffens instantly on impact — making it as capable on track as it is on the daily commute.
Please note: this listing covers the chest protector only. Any back protector shown in product images is for illustration purposes and is not included.
Key Features
- Micro-Lock material: soft and ergonomic at rest, hardens on impact for maximum energy absorption
- CE certified to EN 1621-3 Level 1 — meets rigorous European chest armour standards
- Perforated, breathable construction keeps airflow moving during hard efforts on track or long touring days
- Mesh carrier system provides additional ventilation against the chest
- Low-profile, slim build sits discreetly under any jacket without creating pressure points
- Compatible with all Knox back protectors — a straightforward upgrade to any Knox protection system
Micro-Lock Technology: Race-Ready Impact Protection
Knox's Micro-Lock material represents one of the most advanced passive-protection systems in motorcycling. The rate-dependent compound flows freely with body movement under everyday conditions, conforming closely to the chest and ribs for a natural feel on the peg. The moment a sharp impact force is applied — as in a crash — the molecular structure locks, converting the protector into a rigid energy-absorbing shield that significantly reduces residual force transmitted to the chest.
That dual behaviour — soft during riding, hard when it matters — is why Micro-Lock armour is trusted on circuit as well as the street. Paired with a Knox back protector, it completes a full upper-body protection system without the bulk of a traditional hard-shell chest guard.
Comfort and Ergonomics
The Micro-Lock Chest Protector is built with the demanding rider in mind. Its slim, close-fitting silhouette adds negligible bulk beneath a jacket, and the perforated face ensures air can circulate freely even during aggressive track sessions or long summer touring stages. The integrated mesh carrier system aids ventilation further while keeping the protector positioned correctly against the body.
Fit and Adjustment
- One-size design with a flexible adjustment system to achieve a secure, personalised fit
- Close-to-body shaping maximises freedom of movement in the tuck or on the road
- Dedicated attachment system anchors the protector to Knox back protectors for a stable, slip-free position
Fitment and Compatibility
The Knox Micro-Lock Chest Protector is designed as a direct add-on upgrade for the full range of Knox back protectors. It retrofits seamlessly into existing Knox protection vests and systems via the purpose-built attachment interface, requiring no additional hardware.
- Compatible with all Knox back protectors
- Suitable for sport road riding, track use (as a complement to a back protector), touring, and everyday riding
