HJC C10 Blade MC21

HJC C10 - A lightweight, affordable full-face polycarbonate helmet for everyday riding

The HJC C10 stands out as the Korean brand's entry-level benchmark: a shell made of advanced polycarbonate composite, a wide field of view, effective ACS ventilation, and a reliable micrometric buckle. Designed to suit both beginners and riders looking for a simple, comfortable, and well-equipped full-face helmet, the C10 is available in sizes from 3XS to 2XL, catering to both young riders and adults.

HJC C10 Full-Face Helmet: Affordable Protection Without Compromise

Finding a reliable, comfortable, and well-finished full-face helmet at an affordable price isn't always easy. That's exactly the mission HJC set out to achieve with the C10, designed to replace both the older CS-15 for adults and the CL-Y for younger riders.

Its APC (Advanced Polycarbonate Composite) shell was developed using computer-aided design (CAD) tools to provide a precise fit while keeping the weight down. HJC offers four different shell sizes, allowing for better volume distribution based on the chosen helmet size rather than forcing a single shell on all head sizes.

In front of you, the HJ-34P visor--with anti-scratch coating and Pinlock compatibility--offers a field of view that's 10 mm wider than previous generations. The ACS ventilation system circulates air from the front to the back of the helmet to help dissipate heat and moisture, while the antibacterial fabric lining--which is fully removable and washable--makes daily maintenance easy.

Finally, the C10 is built to last: interchangeable cheekpads across all sizes, a micrometric buckle for quick and precise adjustment, and a rear spoiler available as an accessory for riders who spend more time on highways or expressways.

Why choose the HJC C10?

The C10's main selling point is its positioning: a full-face helmet that strikes the right balance between an affordable price and comprehensive features. Unlike a minimalist entry-level helmet, it features a scratch-resistant visor with Pinlock compatibility, active ventilation, and a durable interior.

The four shell sizes also ensure a more consistent fit based on head circumference--a feature often overlooked in more affordable helmets. Available in sizes ranging from 3XS to 2XL, the C10 is suitable for both young riders and adults, making it a practical choice for equipping the whole family with a helmet that shares the same technical foundation.

Finally, its design remains customizable thanks to the rear spoiler available as an accessory, which helps optimize aerodynamics for higher-speed rides.

Comfort and Ventilation

Whether riding in the city, on the open road, or on the highway, the C10 is designed to remain comfortable across a variety of riding conditions. The ACS system circulates air from the front intakes to the rear exhaust vent, helping to remove heat and moisture accumulated during exercise or in hot weather.

The antibacterial fabric interior also promotes faster drying. The inner liner and cheekpads are fully removable and washable, and the cheekpads remain interchangeable regardless of helmet size--a real plus for fine-tuning the fit without changing models.

HJ-34P Visor and Field of View

The HJ-34P visor effectively protects against debris and wind while filtering out 99% of UV rays. Its coating that resists scratches limits premature wear from daily use, and its Pinlock-ready design allows you to easily add an anti-fog lens for morning rides or wet conditions.

The field of view has been widened by 10 mm compared to previous generations, a significant improvement for peripheral visibility in both city traffic and on the open road.

Safety and Features

The HJC C10 meets the European ECE 22.06 standard. Its micrometric buckle allows for quick and precise adjustment of the chin strap, while the APC shell combines lightness and durability thanks to a CAD-optimized design.

Care Instructions

Clean the HJC C10's visor with lukewarm water and a soft microfiber cloth, avoiding any harsh household cleaners that could cause scratches on the anti-scratch coating.

Since the inner liner and cheekpads are removable, wash them regularly by hand with mild soap, then let them air dry away from direct heat sources.

Periodically check that the micrometric buckle, air intakes, and vents are working properly, and ensure the visor is securely fastened, to keep your helmet comfortable and reliable over time.
