Double D-Ring Race-Grade Retention System

The Double D-ring fastening system provides precise chin-strap adjustment and secure retention. Its race-inspired design allows riders to fine-tune the strap tension for a firm and dependable fit.

A properly adjusted retention system is essential for keeping a motorcycle helmet securely positioned on the rider's head during a ride.

The Korda Sonic GP SPI-D comes with a complimentary smoke visor in the box. The additional smoke visor is useful for riders who prefer a darker visor option during bright and sunny riding conditions.

The included smoke visor adds versatility to the helmet's visor setup, allowing riders to choose the appropriate visor for their riding environment.

Multi-Density EPS Impact Protection

Inside the helmet, the multi-density EPS liner uses layered foam construction across important impact zones. The variable-density structure is designed to progressively absorb and manage impact energy while maintaining a comfortable internal fit.

The EPS liner works together with the IRP+ shell to form the core protective structure of the Korda Sonic GP SPI-D full-face helmet.

Advanced Ventilation & Airflow System

Long rides and warm weather demand effective airflow. The Sonic GP SPI-D incorporates an advanced ventilation system with front air intakes, internal airflow channels and rear exhaust ports.

Fresh air enters through the front ventilation openings and travels through internal ducts, while warm air is directed toward the rear exhaust outlets. This airflow-focused design helps improve thermal comfort during daily commuting and longer motorcycle rides.

Aerodynamic Rear Spoiler for Sport Riding

The aero rear spoiler gives the Korda Sonic GP SPI-D its sport-focused aerodynamic character. The rear profile is designed to improve airflow management, support stability and reduce aerodynamic drag during higher-speed riding.

Korda Sonic GP SPI-D Helmet Maintenance Guide

Regular motorcycle helmet maintenance is essential for keeping the helmet clean, comfortable and ready for use. Moisture can accumulate inside the helmet after riding, particularly in hot and humid conditions. After every ride, place the helmet in a well-ventilated area and leave the visor slightly open to allow air circulation.

Allow the helmet to dry naturally before storing it. Avoid hanging the helmet on a motorcycle's rear-view mirror. Prolonged pressure from the mirror stem can potentially create indentations in the EPS liner, while dust and road grime on the mirror can transfer into the helmet interior.

How to Clean the Korda Sonic GP SPI-D Helmet

Cleaning the outer shell and visor is simple. Use clean water and a soft microfiber cloth. Before wiping, wet the surface to loosen dust and road particles. This helps reduce the possibility of scratches caused by dry debris.

Gently wipe the shell and visor with a clean microfiber cloth without applying excessive pressure. Avoid using petrol, thinner, industrial solvents, ammonia-based glass cleaners or harsh chemical sprays, as these products may damage paint finishes, visor coatings, rubber seals or other helmet components.

How to Clean the Removable Helmet Liners

Remove the interior padding carefully and hand-wash removable liners using mild detergent and room-temperature or lukewarm water. Avoid aggressive wringing, twisting or squeezing because excessive force can shift or deform the internal foam and affect the helmet's fit.

After washing, gently press out excess water and allow the padding to dry naturally under a fan. Avoid direct heat sources. Helmet padding can retain moisture for an extended period, so make sure the liners are completely dry before reinstalling them.

Installing damp padding can contribute to unpleasant odors, fungal growth and premature deterioration of the interior materials.

Double D-Ring Retention System Maintenance

Inspect the Double D-ring retention system periodically to ensure the rings, strap and fastening mechanism remain in good working condition. The retention system is responsible for keeping the helmet securely positioned on your head, making proper operation essential.

If you notice unusual wear, damage or a problem with the retention system, stop using the helmet until it has been properly inspected or serviced according to the manufacturer's recommendations.

Helmet Storage & Care Tips

• Allow the helmet to dry naturally after riding.
• Store the helmet in a cool, dry and well-ventilated location.
• Avoid prolonged exposure to direct sunlight when storing the helmet.
• Keep the visor slightly open while drying the helmet.
• Do not hang the helmet on a motorcycle rear-view mirror.
• Clean dust and road grime before they build up on the shell or visor.
• Use only mild cleaning products and clean microfiber cloths.
• Ensure removable liners are completely dry before reinstalling them.
• Inspect the retention system regularly.
• Inspect the helmet carefully after any significant drop or impact.

Protect Your Helmet, Protect Your Ride

A motorcycle helmet is safety equipment designed to protect your head during a critical moment. Its protective performance depends on its structural integrity, correct fit, secure retention system and proper maintenance.

Keep your Korda Sonic GP SPI-D clean and dry, maintain the interior liners, inspect the retention system and check the helmet after drops or impacts. Proper care helps ensure your helmet remains in the best possible condition for the job it was designed to perform.
