Motorcycle airbag jackets and vests are a relatively new technology for road bikes, so join us as we dig into this leading-edge safety gear.
There are two triggering systems used in these jackets; tethered and non-tethered.
We go into more detail below the reviews, but essentially a tethered airbag requires it to be physically connected to the motorcycle, whilst a non-tethered system uses wireless technology to trigger inflation.
Let’s have a look at some of the various products available:
Helite Touring Air Inflatable Textile Jacket – Tethered
This textile jacket from Helite is an excellent piece of motorcycle clothing – even before considering the airbags.
It uses 600D Cordura fabric with reinforced 1000D sections on the elbows and shoulders and features a waterproof, breathable membrane layer.
A removable thermal liner with comfort mesh means year-round use.
The airbag features are also top-notch. The head, neck, and spine are stabilized, preventing hyperextension, and your internal organs are better protected from impact.
While this is a tethered solution, it uses a multi-directional triggering system. This means the vest inflates in every situation, including when the rider is struck from behind.
This is a quality jacket with the added bonus of integrated airbags. It stands on its own as year-round technical riding gear – waterproof, windproof, durable and warm.
- Great all-round jacket
- Multi-directional triggering system
- Waterproof, windproof, and with a removable thermal liner
- Arguably less effective than smart/electronic solutions
Helite Airnest HV Inflatable Airvest – Tethered
This hi-vis vest is designed to be worn over your jacket.
It fastens in the front and uses 3D air mesh panels for comfort and airflow.
As a tethered solution, this jacket inflates when the lanyard is pulled on by a force greater than 25kg (approx). And it does this quickly, taking less than 0.1 seconds.
In an accident, the inflated panels offer excellent protection to the back, neck, coccyx, ribs, and chest.
The vest also features an integrated Knox back protector and an external pocket for storing essentials.
This is a great product from Helite and comes with a good reputation.
One unexpected bonus – people may mistake you for a police officer because of the hi-vis and get out of your way. Pair this jacket with a white bike, and you’ll own the road.
Jokes aside, this is a great tethered vest that you’ll barely notice you’re wearing (unless you look at its bright colour).
- Hi-vis for added safety
- Good protection
- Integrated back protector
- Some people hate hi-vis
Ixon IX Airbag UO3 – Non-Tethered
This smart airbag vest from Ixon is designed to be worn under your jacket. And at only 1.3kg, it’s comfortable and barely noticeable.
It uses stretch fabric for an ergonomic fit and to help it stay in place in the event of an accident. A 3D mesh and breathable fabric also help with fit and comfort.
As a smart solution, this doesn’t require any lanyard or sensors connected to the bike, meaning total freedom of movement.
Rider monitoring occurs 1000 times per second, meaning ultra-fast detection and inflation times (under 60ms).
The intelligent tech behind this is upgradable via PC and collects data for customized protection.
The drawback here is that a subscription to the In&Motion website is required for the vest to function – a pretty big caveat. This is, however, an excellent, high-tech piece of kit.
If you have no qualms about making recurring payments after the initial purchase, this is a good option.
- Quality protection
- Integrated back protection
- No connection to your bike
- Requires a subscription to work
Klim Ai-1 Airbag Vest – Non-Tethered
This lightweight smart vest from Klim uses a breathable, stretch textile construction with mesh for a comfortable fit.
It sits under your jacket and features an integrated CE level 1 back protector.
Like the example from Ixon, this vest uses an autonomous, wireless monitoring system without any connection to your bike.
Information on rider position and speed is monitored 1000 times per second. This means lightning-fast deployment in the event of an accident.
One feature we like is the indicator LEDs that tell you battery status before riding – convenient.
Its intelligent firmware is upgradable through WiFi or the app, which brings us onto the next, less stellar point.
The Klim vest requires a subscription to the In&Motion website to function. This will immediately put some people off.
But if you’re willing to pay a subscription fee, this is an excellent piece of kit.
- Comfortable, lightweight, and slim
- LED battery indicators
- Requires a subscription
Motorcycle airbags fulfil the same function as their counterparts in cars. Equestrians first used similar devices. Horse riding doesn’t involve the same speeds as motorcycling, but injuries from falling are common. Self-inflating vests seemed to mitigate that risk.
Like most innovations in motorcycle equipment, rider airbags were first tested on the professional racing circuit. And the jury is in – airbags do help protect you in an accident!
Broadly speaking, there are two kinds of solutions here – tethered and electronic.
Tethered air vests use a lanyard to connect to a point on your bike and function similarly to a kill cord on a wave ski or outboard motor.
But, rather than killing the engine, the lanyard on an air vest pulls a pin that pierces a CO2 canister. This canister then inflates the panels in the vest/jacket in under a second.
Typically, it takes around 25-30kg of force to get the needle to perforate. This makes accidental inflation unlikely. However, being hit from the back won’t always generate enough force to inflate the vest due to the lanyard design.
- Generally cheaper
- Tried and tested over 20+ years
- Won’t always inflate when rear-ended
Non-Tethered Electronic/Sensor/Smart Solutions
Smart airbag vests and jackets use accelerometers, gyroscopes, and other sensors to monitor rider position many times per second.
Any abrupt change in speed or position will trigger the vest/jacket to inflate. This type of solution uses a huge amount of data and a complex algorithm to ensure inflation only occurs in an accident.
Smart vests/jackets also offer protection when hit from behind, as they can sense this motion and don’t depend on a lanyard being pulled away from the bike.
- No lanyard to remember
- Effective protection – even from being rear-ended
- Generally more expensive
- The subscription model annoys some people (more info below)
Some solutions require a yearly subscription to get the most from your purchase (or use it all in some cases).
Vests from Klim, for example, require an additional purchase (either a one-time buy or a monthly/yearly subscription) to the company In&Motion to function. The “brain” of the unit won’t activate and pair with the smartphone app without doing this.
Your subscription will also mean regular updates to the algorithm and optimal function of your device. Nonetheless, we are not entirely convinced by this.
Locking safety features behind a paywall for a product you’ve already paid for is hard to stomach. The product should, at a minimum, continue to function without firmware updates.
How They Work
Watch the video below to see how these things deploy in the real world.
It is important to understand that tethered jackets are effective in some accident scenarios but not others.
Riding into a brick wall (should you feel the need!) will not activate the jacket on time because there is no distance created to put tension on the lead and activate the inflating mechanism.
Hitting a car and flying over its roof is much better (can’t wait!) because the rider will very quickly become separated from the machine, and the lead will become tight and activate the jacket well before you make an impact.
They probably hope you’ll never use it at all. Some come with a limited guarantee, although in the event of failure, it’s unlikely you’ll be around to get your money back! Ok, you get the idea.
Non-tethered motorcycle airbags do not have the above limitations as they use sensors to detect rider position and can deploy instantly when they sense and impact from any direction.
The motorcycle airbag doesn’t give all-around protection because it can’t. Resembling a life-jacket or scuba diver’s buoyancy control device, it only covers the chest and back areas.
The good news is that once fully inflated, preferably before impact, the rear coverage extends right up to the back of the helmet, acting as a temporary neck brace.
There is plenty of cushioning down the back below the pelvis area, and the chest is completely covered.
Legs and arms are still vulnerable, but the vital organs of the torso are protected.
How to wear it
Riders may choose to wear an airbag device under or over their regular riding jackets if the inflation isn’t restricted. That would be unlikely given the temporary pressure of 1.35kg per square centimetre it exerts when deployed.
They’re also less likely to be punctured or damaged during an accident if worn under an existing jacket, but you’ll probably have other things to worry about!
A rider also has the option of doubling up. Choose an airbag device with a bright fluorescent colour, and you also have a high-viz safety jacket.
Another option is the integrated jacket – a normal motorcycle jacket with a built-in inflatable airbag device.
Can I reuse a motorcycle airbag?
Yes, provided it hasn’t been punctured or damaged, you can reuse a motorcycle airbag. Buy a new CO2 cartridge and replace it; you’ll be ready and equipped for your next fall!
Can airbag vests fire accidentally?
Accidental deployment is unlikely given the tension of around 30kg required to activate the inflation mechanism. If you park your bike and walk away forcefully without remembering to disconnect the lead, the consequences are more likely to be embarrassing than dangerous.
Are motorcycle airbags suitable for pillion riders?
Yes, pillion passengers can wear airbags too by attaching their leads to somewhere solid on the bike. As long as it doesn’t restrict either individual while on the road or become caught in any moving parts, it will deploy as described if needed.
The airbags, when bought separately, may appear expensive compared to a normal jacket with a similar price tag.
However, an integrated model avoids duplication and absorbs much of the cost.
A rider has to decide whether protecting these vital areas can be achieved by hard armour at a lesser cost or if the separate airbag option is worth the extra expense.
Just don’t forget to connect the cord!
