CE Armor Levels Explained: Level 1 vs Level 2

CE Level 1 and Level 2 are printed on armor tags and mentioned in gear specs constantly, but most product pages treat them as interchangeable marketing terms. They're not. There's a real performance difference between them, and knowing which level covers which part of your body — and why — will change how you evaluate a jacket or pair of gloves.
What the Numbers Actually Mean
Both CE levels are defined by European standards — primarily EN 13594 (gloves) and EN 13595 (jackets and suits) for motorcycle-specific applications. The test method is the same for both levels: a drop tower drives the armor sample onto a measurement device at a defined energy level, and the transmitted force on the other side is recorded.
The difference is the threshold:
- Level 1: Transmitted force must not exceed 18 kN on average, with no single reading above 24 kN
- Level 2: Transmitted force must not exceed 9 kN on average, with no single reading above 12 kN
Level 2 armor absorbs twice the energy before transmitting the same impact force to your body. That's not a minor difference. An elbow hitting pavement at speed generates significantly more energy than the certification floor tests for, which is why the gap between levels matters more at higher impact scenarios.
Critically, these tests are conducted by accredited third-party labs — not self-certified by manufacturers. That's a meaningful distinction compared to some other gear certifications.
Body Regions Covered
CE armor certification applies to specific impact zones depending on the garment type:
Jackets and suits (EN 13595):
- Shoulders
- Elbows/forearms
- Back (separate CE standard, EN 13158, or jacket-incorporated provisions)
Gloves (EN 13594):
- Palm
- Knuckles
- Fingers (on higher-rated gloves)
- Wrist/cuff
Pants (EN 13595):
- Knees
- Hips
Hip protectors have their own designation and are often excluded from base jacket ratings. Back protectors are CE-rated separately, which is why a jacket can advertise full CE certification while shipping with a minimal back pad.

Which Regions Get Hit Most
Crash data consistently shows elbows and shoulders take the highest frequency of primary impacts in slides and lowsides. Knees follow. This is where the level difference has the most practical significance:
Elbows — High impact velocity in even moderate speed slides. Level 2 is worth having here.
Shoulders — Primary contact point in many lowside crashes. Level 2 meaningful, though harder to fit in slim jacket designs.
Back — Statistically less likely to be the first impact point in a lowside, but catastrophic when it is. Most stock jacket back armor is Level 1 foam that barely clears the threshold.
Knees — High contact frequency in crashes. Level 2 knee armor in pants is a worthwhile upgrade for aggressive riding.
Why Most Stock Jacket Armor Is Level 1
Manufacturing and fit constraints drive most of this. Level 2 armor tends to be thicker, stiffer, or heavier than Level 1 — at least in traditional foam formulations. Jacket makers designing to a price point include Level 1 because it meets spec, adds minimal bulk, and keeps the jacket sellable at its target retail.
There's also a rider behavior factor: thick, stiff armor gets removed. Manufacturers have learned that riders pull out uncomfortable armor, making Level 1 flexible inserts a pragmatic compromise in some cases.
The arrival of softer Level 2 materials like D3O and Alpinestars' Nucleon series has started to close this gap — Level 2 protection no longer automatically means a rigid hockey puck on your elbow.
When to Upgrade to Level 2
Track days — No debate. Every impact zone should be Level 2. The speed differential in a track off is higher, and the runoff surfaces vary.
High-speed touring — Highway riding at sustained speeds means higher-energy impacts if you go down. Level 2 elbows and shoulders are a reasonable standard.
Aggressive street riding — If you're pushing pace on canyon roads or commuting in heavy traffic where a lowside is a realistic scenario, Level 2 at the primary impact zones makes sense.
Wrist protection in gloves — Often overlooked, but wrist impacts in crashes are common. EN 13594 Level 2 certified gloves are the standard to target. Our guide to [motorcycle glove safety](https://motogearrater.com/complete-guide-motorcycle-glove-safety) covers this in full detail.
D3O vs Knox vs Alpinestars Nucleon vs Foam Inserts
D3O — Rate-sensitive polymer that's soft and flexible at low stress, stiffens on impact. Available in both Level 1 and Level 2 formulations. Extremely popular as an OEM insert and aftermarket upgrade. Thin profile makes it comfortable.
Knox Micro-Lock and Flexiform — Knox has been engineering motorcycle armor longer than most brands. Their Flexiform back protectors and Micro-Lock limb armor are well-regarded for combining Level 2 certification with reasonable flexibility. Used in a wide range of mid-to-premium jackets.
Alpinestars Nucleon — Alpinestars' proprietary armor line, available in Level 1 (Bio Armor) and Level 2 (Nucleon KR-2i and related). The back protector versions are among the most tested and trusted standalone options.
Standard foam inserts — The baseline CE Level 1 foam pads included in most budget jackets. They meet the standard; they don't exceed it. Easy to swap out for any of the above.
Aftermarket upgrades are straightforward in most cases: pull out the stock insert, check the jacket's armor pocket dimensions, order a compatible Level 2 replacement. D3O's Ghost and T5 EVO back pads fit most standard jacket back pockets.
Frequently Asked Questions
Is CE Level 2 armor significantly better than Level 1?
Yes. Level 2 armor must transmit no more than 9 kN of average force versus 18 kN for Level 1 — half the transmitted force at the same impact energy. In a real crash, that difference is meaningful, particularly for elbows and shoulders which absorb primary impact in most lowside crashes.
Can I upgrade jacket armor to Level 2 aftermarket?
In most cases, yes. Jackets with armor pockets at the elbows, shoulders, and back accept aftermarket inserts. D3O, Knox, and Alpinestars all sell compatible Level 2 replacement pieces. Measure the pocket dimensions before ordering.
Are gloves CE Level 1 or Level 2?
Gloves are rated under EN 13594, which also uses Level 1 and Level 2 designations. Most mid-range gloves ship with Level 1 knuckle and palm protection. Premium sport and track gloves typically carry Level 2 certification.
Does CE Level 2 armor add significant bulk or weight?
It depends on the material. Traditional foam Level 2 armor is noticeably thicker. Modern soft-impact materials like D3O Level 2 are only marginally bulkier than their Level 1 equivalents — the difference in everyday wear is minimal.
Why do some jackets advertise CE certification without specifying the level?
Because "CE certified" is a minimum compliance claim, not a performance claim. If a product listing doesn't specify Level 1 or Level 2, assume it's Level 1 or check the armor tag directly. Reputable manufacturers specify the level clearly.
