FAQ

As a general safety guideline, a motorcycle helmet should be replaced every 3 to 5 years from the date of first use — even if it has not been involved in a crash.

Helmets are constructed from materials that naturally degrade over time:

• EPS (Expanded Polystyrene) liner — designed to absorb impact energy — can gradually lose its protective performance due to heat cycles, moisture, UV exposure, and general ageing.
• Outer shell materials may experience long-term environmental stress.
• Interior comfort padding compresses with use, which can affect fit stability and retention performance.

You should replace your helmet immediately if:

• It has experienced any impact or crash, regardless of visible damage.
• You notice cracks, loose components, or structural deformation.
• The fit becomes loose or unstable.

A motorcycle helmet is engineered as a single-impact energy management system. Once the EPS liner absorbs significant force, its structural integrity is permanently compromised.

Usage conditions, riding frequency, storage habits, and environmental exposure all influence lifespan. Riders in high-heat, high-UV, or high-humidity environments may experience accelerated material ageing.

When it comes to protective equipment, performance consistency matters more than appearance.
Your helmet is not a lifetime product. It’s a performance safety device.
When in doubt, replace it.

Choosing the correct helmet size is critical for both safety performance and long-term comfort. A helmet must fit securely to manage impact energy effectively.

Step 1: Measure Your Head Correctly

Use a soft measuring tape and measure the circumference of your head:

• Wrap it horizontally around the widest part of your head
• Position it approximately 1–2 cm above your eyebrows
• Keep the tape level around the back of your head

Record the measurement in centimetres and refer to GRACSHAW’s official size chart. Always follow the specific GRACSHAW sizing guide, as sizing can vary between brands and models.

Step 2: Check the Fit

A properly fitted helmet should:

• Feel snug and evenly firm around the entire head
• Sit level (not tilted backwards or forward)
• Have no pressure hotspots or sharp discomfort
• Move your skin slightly when rotated side to side

When the chin strap is secured:

• The helmet should not roll off forward or backward
• It should not shift excessively when you shake your head

New helmets will feel tighter at first. The interior padding will naturally settle and conform after several hours of riding.

If a helmet feels comfortable immediately because it is loose, it is likely too large.
If it causes sharp, localised pain within minutes, the size or internal shape may be incorrect.

A helmet should feel secure — not tight to the point of pain, but firm enough to remain stable during impact.

Proper fit is not optional. It is fundamental to how the helmet performs in a crash.

Yes, you can replace or customise interior padding for a better fit.

Only use Genuine GRACSHAW official parts and accessories from GRACSHAW Authorised Dealers and comfort padding intended for your model. Never modify the EPS liner or structural components.

Proper internal fit enhances both safety and comfort — but safety must always come first.

Regular cleaning maintains hygiene, preserves material integrity, and extends the functional lifespan of your helmet. Proper care also prevents premature degradation of liners, adhesives, and visor coatings.

Exterior Shell Cleaning

Frequency: As needed, depending on riding conditions.

Procedure:

1. Rinse the helmet with lukewarm water to remove loose debris.
2. Use a mild, non-abrasive soap solution.
3. Clean with a soft microfiber cloth or sponge.
4. Rinse thoroughly.
5. Air dry at room temperature.

Avoid:

• Benzene Cleaners
• Solvent-based cleaners
• Petroleum products
• Alcohol or ammonia-based chemicals
• Abrasive pads or brushes

Harsh chemicals can weaken shell materials and damage protective finishes.

2. Interior Padding Cleaning

1. Remove them carefully.
2. Hand wash using mild soap in lukewarm water.
3. Gently press — do not twist or wring.
4. Rinse thoroughly.
5. Air dry completely before reinstalling (this may take 24 hours).

Never use a washing machine, dryer, or direct heat source.

3. Disinfection Best Practices

To disinfect safely:

• Use helmet-specific antibacterial sprays.
• Ensure products are non-alcohol-based to prevent material degradation.
• Allow proper ventilation and complete drying before storage.

Excessive moisture trapped inside the helmet can promote odor and microbial growth.

5. Drying and Storage

• Always air dry at room temperature.
• Avoid direct sunlight for extended periods.
• Do not use hair dryers or heaters.
• Store in a cool, dry location away from chemicals or fuel vapors.

A helmet is a precision-engineered safety device.
Improper cleaning — especially with aggressive chemicals or heat — can compromise structural materials and performance.

Clean regularly. Dry completely. Avoid harsh substances.
Proper maintenance preserves both hygiene and protection.

1. Remove the visor if the system allows.
2. Rinse off dust before wiping.
3. Use warm water and mild soap.
4. Dry with a clean microfiber cloth.

For stubborn debris (e.g., insects), place a damp cloth over the visor for several minutes to soften the residue before wiping it off.

Important:
Do not use benzene or glass cleaners, as ammonia can degrade visor coatings and KLEARAF anti-fog treatments.

Your visor (shield) is a critical optical and protective component. Clear vision directly affects reaction time, hazard detection, and riding safety. A compromised visor should never be ignored.

You should replace your visor if any of the following occur:

Visible Scratches That Affect Vision.

Cracks or Impact Damage.

General Wear Timeline.

There is no fixed replacement interval, as lifespan depends on:

• Riding frequency
• Cleaning habits
• Environmental exposure
• Storage conditions

For frequent riders, replacing the visor every 1–2 years is common to maintain optimal optical performance.

A visor is not just a wind barrier — it is your primary optical interface with the road.

If clarity, structural integrity, or coating performance is compromised, replacement is the safest decision with our GRACSHAW Authorised Dealers near you.

If the Helmet Fell Off a Seat or Handlebar (Unoccupied)

If the helmet fell:

• From a low height
• Onto a smooth surface
• Without a rider’s head inside

The risk is generally lower because the helmet was not supporting head mass during impact. In many cases, replacement is not necessary.

However, inspect carefully for:

• Cracks in the shell
• Dents or soft spots
• Loose internal components
• Rattling sounds
• Visor misalignment

• Dropped or impacted during a crash: Replace immediately.

When impact protection is uncertain, contact the GRACHSAW or authorised dealer for inspection guidance.

Helmets are protective equipment — not cosmetic items. External appearance does not reliably indicate internal structural condition.

When impact protection is uncertain, the safest decision is replacement.

Wind noise can come from multiple sources, and it is not always a helmet defect. It is usually the result of airflow interaction between the helmet, the rider, and the motorcycle.

Here are the most common causes:

1. Helmet Fit and Seal

A helmet that does not fit correctly can allow turbulent air to enter:

• Loose fit around the cheeks or jaw area
• Incomplete neck roll seal
• Incorrect size or internal shape

Even small gaps can significantly increase wind noise at speed.

2. Visor and Vent Sealing

Wind noise may increase if:

• The visor is not fully sealed against the eye port
• Visor mechanisms are worn or misaligned
• Vent sliders are partially open or damaged

Check that the visor locks firmly and that vents open and close smoothly.

3. Motorcycle Wind Protection and Turbulence

Often, the motorcycle itself is the main contributor:

• Windscreens can create turbulent airflow at helmet height
• Naked bikes, touring bikes, and scooters all produce different wind patterns
• Seat height and rider posture change how air strikes the helmet

Changing windscreen height or riding position can dramatically alter noise levels.

4. External Factors

• Crosswinds
• Head movement
• Open collars, hoodies, or loose clothing around the neck

These can introduce additional turbulence and noise.

Important Note on Expectations

No motorcycle helmet is completely silent.
Helmets are designed to balance ventilation, stability, visibility, and comfort — and airflow noise is an inherent trade-off.

If wind noise is excessive:

• Verify proper fit
• Ensure visor and vents are fully sealed
• Consider ear protection for long-distance riding

Wind noise is usually a system interaction issue, not a single failure point.

CAN I APPLY STICKERS OR DECALS SAFELY?

Yes — but only if you follow proper precautions. Helmets are precision-engineered safety devices, and incorrect application of stickers or decals can compromise materials or finishes.

Stickers are cosmetic only. They do not enhance protection, and improper application can reduce shell integrity or damage coatings.

When done carefully, applying decals is safe — but always respect the helmet’s materials and structure.
