Motorcyclists, be it pro riders or beginners have the risk of motorcycle accidents which can cause an injury to the spine. A damaged spine is a real serious concern and can even involve disability, paralysis or even death. This is why wearing a certified spine/back protector while riding a motorcycle is a must for racers or street commuters.

In this blog, we have discussed various armour protection ratings, testing setups, European Standards for back/spine protectors, types of back protectors and the most widely used back protectors by motorcyclists globally.

Motorcycle Armour Protection Rating

Motorcycle armour is one of the motorcycle riding gear that needs to confront to safety standards. In the UK and many countries, motorcycle gears have to be “CE Approved” and you should always buy the spine protector that is CE Certified.

CE Ratings are further classified into CE-1 and CE-2. Compared to CE-2, CE-1 are cheaper and offers a lower level of protection. CE-2 have high protection and cost more than CE-1 motorcycle armours.

Levels of European Standards for Protective clothing against external impacts


This safety rating covers all body parts like armours designed for protection motorcyclists knee, lower leg, elbows, forearm except spine/back. For spine protective gears, EN1621-2 is the European Standard for spine armours.

In the test setup, a 5 kg mass has a dimension of 40x30 mm is made to strike a test sample which is placed on top of a hemispherical dome standing at a height of 50 mm. Nine tests are performed with kinetic energy at impact not exceeding 50 KN and based on the average transmitted force, there are two levels with EN1621-1

EN1621-1 Level 1: average transmitted energy is less than 35 KN

EN1621-2 Level 2: less than 20 kN


EN1621-2 covers European Safety Standards for spine/back armours. The test setup is similar to EN1621-1 but differs in the impact and configuration of the anvil. Here, the mass is a prism having dimensions 160x50x30.8 mm and a radius of 12.5 mm. The axis of the cylindrical anvil is directed in the direction of impact and has a radius of 50 mm and a height of 190mm.

EN1621-2 Level 1: average peak value must be less than 18 kN, with no single test value exceeding 24 kN

EN1621-2 Level 2: average peak value must be less than 9 kN, with no single test value exceeding 12 kN

Materials of Motorcycle Spine Protectors


Protectors made from foam are either open-celled or closed celled. Soft foamed offer very little protection while hard foamed absorb impact for once and needs replacement after the incident.

Memory Foam

These are dense foamed and offer more protection than foam type spine protectors by slowly rebounding after getting compressed.

Hard Plastic

These armours do not on their own protection from the impact but offer resistance to punctures or abrasion. They are used with some other material that lines inside, toward the spine.


These back protectors are gel-based impact absorbers and having varying densities. This type of protector fit close to the body and offer comfort.


This material has a very high resistance to impact and at the same time comfortable fit. This material remains soft until it gets impacted. Upon impact, the material quickly forms a rigid and protective mass. A viscoelastic material is used in the manufacture of BMW apparels, jackets, hand gloves, armours like D3O, Knox Microlock, SAS-TEC and many more.
