Do You Need a CE Level 2 Back Protector?
If you ride at road speed, a CE Level 2 back protector is one of the few upgrades genuinely worth prioritising, because the spine is the one thing you cannot rehabilitate your way out of. Under EN 1621-2, Level 2 must keep transmitted force under 9 kN against 18 kN for Level 1, the widest gap between levels anywhere in motorcycle armor. Before you shop, though, check what is already in your jacket: that flat pad in the back pocket is very often uncertified foam, not a protector.
Key takeaways
- Many jackets ship with a foam comfort pad, not a certified protector. If there is no CE mark, it is not armor.
- Back protectors are graded under EN 1621-2: Level 1 ≤ 18 kN, Level 2 ≤ 9 kN transmitted.
- Type A vs Type B is about coverage area, not strength. Type B covers more of your back.
- Good coverage runs from the base of the neck to the lumbar, and it must stay there when you ride.
- Modern soft, visco-elastic protectors now reach Level 2, so comfort is no longer the excuse it once was.

First, check what is actually in your jacket
This is the part that surprises riders. A large share of jackets, including good ones, arrive with a plain slab of foam in the back pocket. It is there to stop the pocket flapping and to make the jacket sit nicely, and manufacturers usually describe the real back protector as an optional extra. Pull yours out and look for a printed CE mark and an EN 1621-2 reference. No marking means no certification, and no certification means nobody has measured what it does.
✗ Comfort pad (not armor)
- Plain, uniform foam with no printing
- No CE mark, no EN 1621-2 reference
- Thin, light and completely flat
- Often described as a “back pad” in the spec sheet
✓ Certified back protector
- Printed CE mark and EN 1621-2
- States Level 1 or Level 2
- States Type A or Type B
- Shaped and articulated, not a flat slab
What EN 1621-2 actually requires
Back protectors are tested the same way as limb armor, with a 50-joule strike and a sensor measuring what gets through. The difference is the pass mark: because it is your spine, the thresholds are far stricter than for an elbow or knee.
| Level | Average force allowed | No single hit above | In plain terms |
|---|---|---|---|
| Level 1 | 18 kN | 24 kN | The certified baseline |
| Level 2 | 9 kN | 12 kN | Halves the force reaching your spine |
Do not compare levels across body parts. A Level 2 elbow protector may transmit up to 20 kN. A Level 2 back protector must stay under 9 kN. Same words on the label, a much harder test. We break the whole system down in what CE-rated armor means.
Type A or Type B: how much of your back is covered
Alongside the level, every back protector carries a type, and this one is about area rather than impact performance. Type B covers more of your back than Type A. Both can be Level 1 or Level 2, so you will see combinations like “Level 2, Type B”, which is the most protective pairing.
Insert, strap-on or vest?
Pocket insert
Replaces the foam pad in your jacket. Cheapest and simplest upgrade, and invisible once fitted.
Watch for: it can shift with the jacket rather than staying on your spine.
Strap-on harness
Worn against your body with shoulder and waist straps, so it stays put and works under any jacket.
Watch for: an extra layer to put on, and a little warmer.
Protector vest
A garment built to carry armor, often with chest protection too. Falls under EN 17092 Class C.
Watch for: bulk under a close-fitting jacket.
That Class C marking is worth understanding, because a vest is rated as a garment even though it offers no abrasion protection of its own. Our guide to EN 17092 and the AAA to C classes explains where it fits.
Getting the fit right
A back protector only guards what it covers, and only while it is in the right place. Most are sized by back length rather than jacket size, so measure from the base of your neck to the top of your hips and buy to that.
✓ Do
- Check coverage while leaned onto the bars, not standing up
- Size by back length, neck to hips
- Choose articulated panels so it flexes as you move
- Make sure it sits centred on the spine
✗ Avoid
- A protector that rides up and bares your lower back
- Assuming the foam pad that came with the jacket counts
- Buying by jacket size instead of back length
- A rigid board that stops you tucking or turning
Hard shell or soft visco-elastic?
Hard shell
Segmented polymer plates over foam. Excellent at spreading a sharp, concentrated hit and usually cheaper for a given level.
Best for: value, and riders who want a visible physical barrier.
Soft / visco-elastic
Flexible material that stiffens instantly on impact. Moves with you, then hardens when struck. Plenty of these now certify at Level 2.
Best for: all-day comfort, touring, and gear you will not leave at home.
A decade ago the trade-off was real: Level 2 meant a stiff board down your spine. Soft protectors have largely closed that gap, which removes the main reason riders used to settle for Level 1 on their back.
So do you actually need one?
Yes, go Level 2
Motorway and touring miles, fast back roads, track days, or any riding where a get-off happens at speed.
Level 1 is still a real upgrade
If budget or bulk is the barrier, certified Level 1 beats the foam pad by a wide margin. Anything certified beats nothing.
Worth it even in town
Low-speed spills still land you on your back on a kerb. The spine does not heal like a collarbone does.
The honest answer: of everything in a jacket, the back protector is the piece most often missing and the hardest injury to come back from. If you upgrade one thing this year, make it this.

Frequently asked questions
Do I need a Level 2 back protector?
If you ride at road or motorway speed, it is the upgrade worth prioritising. Level 2 keeps transmitted force under 9 kN against 18 kN for Level 1, and spinal injuries are the hardest to recover from. Where budget or bulk rules it out, certified Level 1 is still far better than an uncertified foam pad.
Does my jacket already have a back protector?
Often not. Many jackets ship with a plain foam comfort pad that fills the pocket but carries no certification. Pull it out and look for a printed CE mark and an EN 1621-2 reference. If there is no marking, it is a pad rather than a protector, and the real one is usually sold separately.
What is the difference between Type A and Type B?
Type is about coverage area, not impact performance. Type B covers more of your back than Type A. Both are available in Level 1 and Level 2, so “Level 2, Type B” is the most protective combination you can buy.
Is a Level 2 back protector the same as Level 2 elbow armor?
No. The label wording matches but the tests differ. A Level 2 back protector must keep transmitted force under 9 kN, while a Level 2 elbow protector under EN 1621-1 may transmit up to 20 kN. Back protectors are held to a much tougher standard.
Insert, strap-on harness or vest: which is best?
An insert is simplest and cheapest but can move with the jacket. A strap-on harness sits against your body so it stays on your spine and works under any jacket. A vest carries armor and often adds chest protection. For touring, a harness or vest tends to stay better positioned.
How should a back protector fit?
It should cover from the base of your neck down to your lumbar and stay there while you ride. Size by back length rather than jacket size, and check the coverage while leaned forward onto the bars, since a protector that looks right standing up can ride up in your riding position.
Are soft back protectors as good as hard ones?
Many soft, visco-elastic protectors now certify at Level 2, so on the test numbers they match. They flex as you move and stiffen on impact, which makes them far more comfortable for long days. Hard shells remain good value and spread a sharp, concentrated hit well.
When should a back protector be replaced?
Replace it after any significant impact, even if it looks intact, since the material may have already done its job. Otherwise check it for cracks, permanent dents or hardening with age, and follow any replacement interval the manufacturer prints on the label.
