• SuperCool Interior: Features high-speed drying, antibacterial, and odor-resistant properties. The interior is removable and washable for easy maintenance.
• Efficient Ventilation: Designed to effectively exhaust internal heat from the helmet.
• Adjustable Visor: Visor angle can be adjusted using three screws to protect against mud, small stones, and glare.
• Goggle Band Retention: Ribbed shape from the side to the back of the head helps prevent goggle bands from slipping.
• Intercom Speaker Pockets: Provides dedicated space for speakers, enhancing comfort during intercom use.

Safety Information

Your HJC i50 TONA helmet is designed to meet SG/JIS standards. Always wear a properly fitted helmet when riding. Ensure the chin strap is securely fastened. Never modify your helmet, as this can compromise its protective capabilities. Replace your helmet after any impact, even if visible damage is not apparent.

Setup and Fitting

1. Selecting the Correct Size: Ensure the helmet fits snugly around your head without causing pressure points. The helmet should not move freely when you shake your head.
2. Chin Strap Adjustment: Fasten the chin strap securely under your chin. It should be tight enough so that you cannot pull the helmet off your head by rolling it forward or backward.
3. Visor Adjustment: The visor can be adjusted for angle using the three screws located on the helmet. Loosen the screws, position the visor as desired to block sun or debris, and then tighten the screws firmly.
4. Goggle Fit: Place your goggles over the eye-port. The helmet's ribbed design helps secure the goggle strap in place. Adjust the goggle strap for a comfortable and secure fit.

Operating the Helmet

The HJC i50 TONA helmet is designed for off-road motorcycle use. Its ventilation system and SLID technology work automatically during riding to enhance comfort and safety.

• Ventilation: Air enters through the front intake and is channeled to the rear outlets, effectively expelling hot air from inside the helmet.
• SLID System: This system is integrated into the helmet's liner and functions passively to reduce rotational impact forces in the event of a crash. No user interaction is required for its operation.

Maintenance

• Interior Cleaning: The SuperCool interior lining is removable and washable. Gently remove the pads and wash them by hand with mild soap and water. Allow them to air dry completely before reinserting.
• Exterior Cleaning: Clean the helmet's exterior with a soft cloth and mild soap and water. Avoid abrasive cleaners or solvents, as these can damage the helmet's finish or materials.
• Mouth Vent Maintenance: The mouth vent can be detached with a single screw for easy cleaning if it becomes dirty with mud or dust.
• Storage: Store the helmet in a cool, dry place away from direct sunlight and extreme temperatures.
