Overview

1. Function Description

3. Maintenance Features

The HJC DS-X1 is a motorcycle helmet designed to provide protection and comfort for riders. Its primary function is to safeguard the rider's head from impacts and injuries during accidents, while also offering features that enhance the riding experience.

Function Description:

The core function of the DS-X1 helmet is head protection. It is engineered to absorb and distribute impact forces, thereby reducing the risk of serious head injury or death in the event of a crash. The helmet's design incorporates an advanced polycarbonate composite shell, which is lightweight yet robust, and an impact-absorbent liner to cushion the head. The retention system, consisting of a chin strap with a double "D" ring, ensures the helmet stays securely in place during a ride and in an impact. The helmet also features a visor and shield system to protect the rider's eyes and face from wind, debris, and environmental elements, while maintaining clear visibility. An "ACS" Advanced Channeling Ventilation System is integrated to manage airflow, flushing heat and humidity out of the helmet to keep the rider cool and comfortable.

Usage Features:

The DS-X1 is designed with several features to optimize its use and enhance the rider's experience.

• Selecting the Right Helmet: Proper fit is crucial for the helmet's effectiveness. Riders are instructed to measure their head circumference and use a sizing chart as a reference, but ultimately to try on the helmet to ensure a snug and secure fit. The helmet should fit snugly around the head, with the top pad pressing firmly and cheek pads contacting the cheeks, leaving no space around the brow. The fit should be tested by attempting to rotate the helmet while holding the head still; the helmet should move the skin on the head and face, not slide independently.
• Fastening the Retention System: The chin strap must be fastened as tight as possible under the jaw without causing pain, ensuring there is no slack. This is critical to prevent the helmet from becoming dislodged or knocked off in an accident. The double "D" ring system provides a reliable and secure closure.
• Visor and Shield System: The helmet includes a visor and shield for eye and face protection. The visor is adjustable, allowing riders to position it for optimal visibility, especially in muddy conditions where "roost" protection is needed. The shield is made of polycarbonate with an abrasion-resistant coating, designed to withstand minor scratches. It can be removed and installed for cleaning or replacement. The helmet also features a large eye port, which is designed for maximum visibility and to accommodate goggles comfortably.
• Ventilation System: The "ACS" Advanced Channeling Ventilation System ensures continuous airflow from front to back, which is vital for rider comfort, especially in warm conditions. This system helps to flush out heat and humidity, preventing discomfort and fogging.
• Interior Comfort: The helmet features a plush, Nylex interior with removable and washable crown and cheek pads. This allows for easy cleaning and maintenance, contributing to hygiene and long-term comfort.
• Safety Precautions: Riders are advised to always wear eye protection, even if not using the helmet's face shield, and to lock the face shield in place when riding. Adjustments to helmet accessories should only be made when stopped. Dropping the helmet is discouraged as it can cause unseen damage to the shell or protective foam, compromising its safety. The helmet is designed for one impact only, and should be replaced after any impact, regardless of visible damage.

Maintenance Features:

Maintaining the DS-X1 helmet properly is essential for its longevity and continued protective capability.

• Shell Cleaning: The helmet shell, whether glossy or non-glossy, requires specific cleaning methods. For glossy finishes, automotive cleaning and polishing products are recommended, with caution against over-polishing. For non-glossy finishes, warm water and mild soap are advised, avoiding excessive pressure or rubbing compounds that could alter the finish. Insect repellent and gasoline should be kept away from the helmet as they can damage the shield, shell, and protective foam.
• Interior Cleaning: The removable crown and cheek pads can be machine washed and air-dried, promoting hygiene and preventing odor buildup from sweat and humidity. For non-removable interiors, products designed to eliminate bacteria and mildew are recommended.
• Vent Cleaning: Dirt and debris can accumulate in the ventilation system. Compressed air cans, similar to those used for cleaning computer keyboards, can be used to blow out debris, ideally after removing any removable pads.
• Shield Cleaning: The polycarbonate shield should be cleaned with a weak solution of mild soap and warm water. Harsh agents like hot water, salt water, benzene, thinner, or gasoline should be avoided to preserve the abrasion-resistant coating. Deeply scratched shields should be replaced as they can impair visibility. Tinted shields are for daytime use only.
• Inspection: Regular inspection of the helmet is crucial. Riders should check the shield and shield ratchet, re-tightening screws if necessary (without over-tightening). The helmet should be inspected for any damage, cracks, or worn parts. The retention system (chin strap) should be checked for fraying or ripping. All pads (cheek and crown) must be in place.
• Storage: The helmet should be stored in a cool, dry place, away from pets, other animals, and heat sources exceeding 122°F. It should also be kept in its helmet bag when not in use to prevent accidental surface damage. Prolonged exposure to sunlight can cause fading.
• Replacement: HJC recommends replacing the helmet every 3 to 5 years, even without visible damage, due to the effects of UV rays, adhesive, and component aging. After any impact, the helmet must be replaced immediately. When purchasing a new helmet, the old one should be destroyed to prevent its reuse by others, as the protective foam conforms to the original wearer's head over time.
• Modifications: Modifying the helmet, such as drilling holes, cutting the shell or strap, modifying the retention system, removing parts, painting, or attaching non-HJC accessories, is strongly discouraged as it can compromise the helmet's safety and may increase the risk of serious injury or death.
