Guide to Leather Motorcycle Jacket Armor Inserts

A leather motorcycle jacket without armor protects you from abrasion in a slide but not from the impact force of hitting the ground or an obstacle. Armor inserts fill this gap. Understanding how armor works, what the CE rating system means, and how to select and maintain armor makes you a significantly better-equipped rider.

What Armor Inserts Do

Armor inserts are impact-absorbing pads placed in pockets inside a motorcycle jacket at the elbows, shoulders, and back. They are made from materials that are flexible and comfortable during normal wear but harden on impact to distribute and absorb the force of a crash. Without armor, all of the energy from hitting the ground transfers directly to your body. With armor, that energy is spread over a larger area and partially absorbed by the armor material.

CE Rating Levels Explained

CE armor is rated at two levels. Level 1 armor transmits an average force of less than 18 kilonewtons in testing. Level 2 armor transmits less than 9 kilonewtons, which means it absorbs roughly twice as much impact force. For elbow and shoulder armor, CE Level 1 is the minimum acceptable standard. CE Level 2 is better and is increasingly standard in quality jackets. For back protectors, CE Level 2 is strongly recommended since the spine and kidneys have no other protection.

Armor Placement: Where It Matters

The elbows are the most commonly impacted body part in motorcycle accidents since they are your natural instinct to brace a fall. Shoulder armor protects against direct shoulder impacts. Back armor protects the spine and kidneys from impact against the road or objects. Some jackets also offer chest armor pockets. In a crash, armor only works if it is positioned correctly over the body part it is designed to protect. Check that your armor sits in the right position every time you put on the jacket.

How to Check If Your Armor Fits Correctly

Put on the jacket fully zipped and check that the elbow armor sits directly over your elbow when your arm is slightly bent. The shoulder armor should sit directly over the shoulder joint. If either piece has migrated toward the forearm or upper arm, the armor pocket design may not match your proportions, or the armor may need to be secured with the adjustment tabs present in many jackets. Armor that is not centered over the joint it protects is not providing full protection.

Replacing Old or Damaged Armor

Armor that has taken a significant impact in a crash should be replaced. Impact-absorbing materials are designed to absorb one crash, not multiple. A visually intact piece of armor may have compromised internal structure after impact. Similarly, old armor that has become stiff and brittle from age should be replaced since it may shatter rather than absorb on impact. Replacement armor is available from motorcycle gear retailers and is generally inexpensive compared to the protection it provides.

Adding Armor to a Jacket That Does Not Have Pockets

If you have a leather jacket without armor pockets, a leather tailor can add pockets for CE-rated armor inserts. Alternatively, a CE-rated armored under-shirt provides impact protection beneath any leather jacket including classic motorcycle jackets and flight jackets like the A-2 and G-1 available at legendaryusa.com. This lets you ride in a heritage jacket with modern protection.

Frequently Asked Questions

What is CE Level 1 vs CE Level 2 armor?

CE Level 1 armor transmits less than 18 kilonewtons of force on impact. CE Level 2 transmits less than 9 kilonewtons. Level 2 absorbs roughly twice as much impact energy. Level 2 is recommended for all positions, especially the back.

How often should I replace armor inserts?

Replace after any significant impact in a crash. Otherwise, inspect annually for brittleness or deformation and replace every 5 to 7 years as impact-absorbing materials degrade over time.

Can I use armor from one jacket in a different jacket?

Yes, if the armor dimensions match the pocket size of the new jacket. Standard D3O and foam armor inserts are often interchangeable between jackets of the same size category.

Is a back protector necessary?

The spine is one of the most vulnerable areas in a motorcycle crash. Back armor is strongly recommended. A CE Level 2 back protector provides meaningful protection against spinal injury and is worth including.

What is D3O armor?

D3O is a brand of rate-dependent impact-absorbing material that is flexible during normal wear but stiffens instantly on impact. It is widely used in premium motorcycle armor and provides excellent protection with good comfort.
