3. Setup and Sizing

Proper helmet fit is crucial for safety and comfort. The Valiant II helmet is designed to fit a long oval head shape. If your head shape is intermediate oval or you are between sizes, it is recommended to size up for a better fit.

3.1. Measuring Your Head

1. Locate Your Measuring Tool: Use a flexible measuring tape. If you are using string, wrap it around your head just above your eyebrows, mark the point where it overlaps, then measure using a straight ruler.
2. Measure Your Head: Wrap the measuring tool around the widest part of your head, typically about 1 inch above your eyebrows and ears. Note the circumference in both inches and centimeters.

Refer to the table below to find your corresponding helmet size based on your head circumference.

4. Operating Instructions

4.1. Modular Flip Mechanism

To convert the helmet from full-face to open-face, locate the release button at the bottom of the chin bar. Press the button and slide the chin bar upwards and over the top of the helmet. The chin bar will securely lock into place at the rear, providing an open-face configuration. To return to full-face, reverse the process, ensuring the chin bar latches firmly into position.

4.2. Twin Shield System (Drop-Down Sun Shield)

The helmet features an integrated sun shield. To deploy the sun shield, locate the sliding lever on the side of the helmet (typically on the left). Slide the lever downwards to lower the tinted sun shield. To retract the sun shield, slide the lever upwards. This system allows for quick adaptation to changing light conditions without needing to wear separate sunglasses.

4.3. Quick Release Chin Strap

The chin strap uses a quick-release buckle for ease of use. To fasten, insert the male end of the buckle into the female receiver until it clicks securely. To release, press the red tab on the buckle and pull the male end out. Adjust the strap length for a snug, comfortable fit under your chin.

4.4. Ventilation System

The helmet is equipped with adjustable intake and exhaust vents. Locate the sliders or switches on the top and front of the helmet. Slide them to open or close the vents, allowing you to control airflow and maintain comfort in various weather conditions.

5. Maintenance

5.1. Cleaning the Shell

Clean the helmet shell with a soft, damp cloth and mild soap. Avoid abrasive cleaners, solvents, or petroleum-based products, as these can damage the finish and material. Rinse thoroughly and dry with a soft, clean cloth.

5.2. Visor and Sun Shield Care

Clean the clear visor and integrated sun shield with warm water and a soft cloth. For stubborn dirt, use a helmet-specific visor cleaner. Do not use harsh chemicals or abrasive materials. Ensure the visor is completely dry before closing or storing the helmet. The PinLock insert should be handled with care and cleaned according to its specific instructions.

5.3. Interior Padding

The interior comfort padding is removable and washable. Gently detach the padding from the helmet. Hand wash with mild soap and cool water, or machine wash on a delicate cycle in a laundry bag. Air dry completely before reinserting into the helmet. Do not tumble dry or use harsh detergents.

5.4. Chin Strap Maintenance

Periodically inspect the chin strap and buckle for any signs of wear or damage. Clean the strap with a damp cloth and mild soap. Ensure the quick-release mechanism operates smoothly and locks securely.

6. Troubleshooting

6.1. Visor Not Closing Properly

If the main visor does not close smoothly or completely, check for any obstructions in the visor mechanism or along the seal. Ensure the visor is correctly seated in its pivots. Clean the pivot points and apply a small amount of silicone lubricant if necessary. If the issue persists, inspect the visor for damage or warping and consider replacing it.

6.2. Chin Bar Mechanism Sticking

If the 180-degree flip chin bar mechanism feels stiff or sticky, ensure no debris is lodged in the pivot points. Clean the mechanism thoroughly. Avoid forcing the chin bar. If the issue continues, contact LS2 customer support for assistance.

6.3. Excessive Noise While Riding

While modular helmets may exhibit some noise, excessive wind noise can indicate an improper fit or an issue with the visor/chin bar seal. Ensure the helmet is correctly sized and worn. Check that the main visor and chin bar are fully closed and sealed. Inspect the helmet's seals for any damage or gaps. Adjusting the ventilation can also sometimes affect noise levels.

6.4. Sun Shield Not Operating Smoothly

If the internal sun shield is not deploying or retracting smoothly, check the sliding lever for obstructions. Ensure the mechanism is clean. Avoid applying excessive force. If the problem persists, it may require professional inspection.
