How to properly remove a helmet from a Teldrin Cero motorcycle: instructions with photos and videos

Removing a helmet from a motorcycle Teldrin Zero (popularly known as “Sero”) is a task that at first glance seems simple, but in practice raises questions even among experienced bikers. The design of the fastenings for this model has its own peculiarities: the manufacturer used a combined fastening system with a quick-release mechanism and additional safety latches. Wrong actions may cause damage to the plastic shell of the helmet, scratches on the motorcycle fork, or even breakage of fasteners.

In this article we will look at three official ways removing the helmet (depending on the year of manufacture Teldrin Zero), we will list the necessary tools and show how to avoid common mistakes. We will pay special attention to models 2020–2023, where the fastening system has been modified. If you have never removed a helmet from this motorcycle or have encountered a jammed mechanism, this guide is for you.

⚠️ Important: On motorcycles Teldrin Zero 2026 model helmet mount integrated with system SmartLock. To withdraw, you will need to first unlock it through the mobile application (instructions in section 5).

1. Preparation: What you need to know before removing your helmet

Before you begin dismantling, check two key points:

1. Mounting type - on Teldrin Zero three options are used:
   • 🔧 QuickRelease (quick release, models until 2021)
   • 🔒 DoubleLock (double commit, 2021–2023)
   • 📱 SmartLock (electronic locking, from 2026)

Mechanism condition — if the helmet was not removed for more than 6 months, the fastenings could oxidize. In this case, processing will be required WD-40 or similar composition.

Also prepare your workspace:

• 🛠️ Flat surface (it is better to use a motorcycle stand to avoid falling).
• 🔦 Light source - mounts are often located in hard-to-reach places.
• 🧤 Gloves with rubber pads (prevent slipping when pressing the latches).

⚠️ Attention: On models Teldrin Zero Sport The helmet is attached to the fork via an adapter on the left side. Do not try to remove it by force - this can damage the hydraulic pipes of the brake system located nearby.

2. Method 1: Removing the helmet with the QuickRelease system (until 2021)

This system is the simplest, but has a caveat: if you do not press the safety latch, the helmet will not detach completely and may damage the plastic retainer.

Step by step instructions:

1. Locate on the inside of the helmet (motorcycle side) red plastic button - This is the main unlocker.
2. Press and hold it while pulling the helmet up and a little on yourself.
3. If the helmet does not budge, check second latch (metal lever under the button) - it needs to be moved to the side with a flat-blade screwdriver.

🔹 Common mistake: Bikers forget about the second latch and pull the helmet with force, which leads to breakage of the plastic fastener. If the mechanism is stuck, use silicone lubricant Liqui Moly Silicon-Spray — it does not damage rubber seals.

3. Method 2: DoubleLock (2021-2023 models)

From 2021 Teldrin equipped with double-locking helmets. Here you will need 4 mm hex key (comes with the motorcycle). If you don’t have one, any high-quality tool will do - cheap wrenches can lick off the edges of the bolt.

Algorithm of actions:

1. On the right side of the helmet (looking from the front of the motorcycle) find rubber plug — the locking bolt is hidden under it.
2. Remove the plug and insert the hexagon. Rotate counterclockwise 90° - there should be a click.
3. After that, press the main unlock button (similar to QuickRelease) and remove the helmet.

Step	Action	Possible problem
1	Removing the rubber plug	The plug is stuck - pry it off with a plastic spatula
2	Rotate hexagon	The bolt does not turn - treat it WD-40 and wait 5 minutes
3	Pressing a button	The button does not press - check that the bolt is turned all the way

⚠️ Attention: On some parties 2022 Teldrin Zero the locking bolt had a defective thread. If you feel "resistance with slippage" when turning the key, do not use force - contact the service to replace the fastener under warranty.

4. Method 3: SmartLock (models from 2026)

Latest mounting system requires pre-authorization via app Teldrin Connect. Without this, the helmet cannot be removed - even physical pressure on the latches will not help.

Instructions:

1. Open the application and go to the section Accessories → Helmet.
2. Click Unlock the mount — a timer will appear on the screen for 30 seconds.
3. During this time, click on touch button on the helmet (located under the brand logo).
4. After the beep, pull the helmet up.

🔹 If the application does not see the helmet:

• Check if it is enabled Bluetooth on the phone.
• Make sure the helmet is within 2 meters of the motorcycle.
• Reboot the app or phone.

5. Typical problems and their solutions

Even with the right actions, difficulties can arise. Let's look at the most common ones:

• 🔧 The helmet does not come off after unlocking - the reason is often deformation of the plastic retainer. Try gently rocking the helmet left and right without applying vertical force. If it doesn't help, contact service.
• 🔊 There is a click, but the helmet does not detach — check if it’s caught fastening strap parts of the motorcycle (for example, a mirror or brake lever).
• 🔋 SmartLock does not respond to commands - update the motorcycle firmware via Settings → System → Software Update. In 2026, a critical update was released that fixed blocking bugs.

⚠️ Attention: If after removing your helmet you notice that metal fastening elements are covered with rust, immediately treat them with a rust converter (for example, Hi-Gear HG5717) and apply graphite lubricant. Ignoring corrosion will lead to jamming of the mechanism.

What to do if the helmet is stuck?

If none of the methods help, do not try to remove the helmet by force - this may damage the motorcycle fork. The best option: dismantle the mount along with the helmet (you will need to unscrew the 4 bolts on the fork) and take it to a service center. In 80% of cases, the problem is solved by replacing the spring in the locking mechanism (repair cost starts from 1,200 rubles).

6. Caring for fasteners: how to avoid problems in the future

To make the helmet come off easily, follow these recommendations:

• 🧴 Lubrication — once every 3 months, apply to metal parts of fastenings silicone grease (do not use lithol or grease - they collect dust).
• 🚿 Cleaning — after rain or washing the motorcycle, wipe the mounts with a dry cloth. Moisture is the main cause of corrosion.
• 🔄 Prevention — if the motorcycle has been standing idle for more than a month, take off and put on the helmet once every 2 weeks so that the mechanism does not “stagnate.”

🔹 For models with SmartLock: Update your motorcycle firmware regularly. In 2026 Teldrin released a patch that eliminates a bug with spontaneous locking of the helmet when the motorcycle battery is low (below 12.3 V).

💡

Use only original Teldrin lubricants (part no. TL-SL001) - they are tested for compatibility with the plastic of the helmet and do not cause softening of the seals.

7. Frequently asked questions (FAQ)

Is it possible to remove the helmet without an Allen key on 2021-2023 models?

Theoretically yes, but it's risky. Some bikers use a flathead screwdriver to turn the bolt, but this often ends up stripping the edges. If there is no key, it is better to order a duplicate (article number TL-TOOL-04, cost ~300 rubles).

Why do scratches remain on the fork after removing the helmet?

This occurs due to the incorrect position of the helmet when removing it. Always pull it straight upwithout tilting to the sides. If there are already scratches, use polish for plastic (for example, Sonax Plastic Polish) - it masks minor damage.

How to check that the helmet is fastened correctly before the trip?

Shake the helmet with your hands in different directions - if you hear play of more than 1-2 mm, the mount is not secure enough. Also note lock indicator (green mark on the latch). On models with SmartLock The “Helmet locked” notification should be lit in the application.

Can I install a helmet from another manufacturer on Teldrin Zero?

Technically yes, but it will be required mounting adapter. Officially Teldrin recommends using only original series helmets Z-Line and S-Line, since they have passed crash tests taking into account the characteristics of the motorcycle frame. Non-original helmets may not withstand the load of an accident.

What to do if the helmet cannot be removed after a fall?

In this case do not try to remove it yourself — deformation of fastenings may be invisible, but critical. Contact service Teldrin or to an authorized dealer. In 90% of cases, after an accident, the entire fastening unit must be replaced (cost: from 3,500 rubles).
