HJC C50 Dash MC4

HJC C50 - A lightweight polycarbonate motocross helmet designed for off-road riding

The HJC C50 is a motocross helmet designed to offer an excellent balance of comfort and protection both on the track and during off-road rides. With a wind tunnel-tested APC composite shell, tool-free visor, ACS ventilation, and optimized compatibility with motocross goggles, it combines all the essentials for efficient riding, without any unnecessary frills.

HJC C50 Motocross Helmet: Versatility Designed for Riding

In motocross, a helmet must be lightweight, well-ventilated, and stable enough during acceleration and at full speed. The HJC C50 was developed with this in mind, featuring an APC (Advanced Polycarbonate Composite) shell designed using CAD tools to ensure a precise fit. Two shell sizes allow for better volume distribution based on head circumference.

Its visor has been tested in a wind tunnel using CFD (Computational Fluid Dynamics) simulations to provide maximum stability and reduce drag at high speeds. It can be removed and reattached without tools, saving valuable time during quick changes on the track. The ventilation cover at the mouth is also removable, making it easier to clean after intense sessions.

In terms of comfort, the antibacterial fabric lining promotes better moisture wicking and quick drying. The head liner and cheekpads are removable, washable, and interchangeable across all sizes, allowing you to fine-tune the fit without changing helmets. The C50 also features a dedicated groove for eyeglass temples and a design optimized to provide excellent fit with a motocross goggle.

Why choose the HJC C50?

The C50 stands out first and foremost for its technical sophistication at an affordable price: a wind tunnel-tested shell, a CFD-optimized visor, and an efficient ventilation system--features rarely found together in an entry-level motocross helmet.

Its design, optimized for wearing motocross googles--with a dedicated fit and a groove for glasses--also allows you to ride with a full set of gear without compromising on comfort. Finally, the interchangeable cheekpads across all sizes offer considerable adjustability to fine-tune the fit over time.

Ventilation and Comfort

On the track, exertion and heat build up quickly. The C50's ACS system channels air from the front to the back of the helmet to help wick away heat and moisture, while the removable ventilation cover at the mouth simplifies cleaning after a muddy or dusty session.

The antibacterial lining promotes quick drying, and both the inner liner and cheekpads are fully removable and washable for easy maintenance between rides.

Visor and Aerodynamics

Unlike a full-face road helmet, the C50 features a visor (peak) rather than a shield, as is typical on a motocross helmet designed to be worn with goggles. This visor has been specifically tested in a wind tunnel using CFD simulations to minimize wind resistance and improve stability at high speeds. It can be removed and reattached without tools, a practical advantage for maintenance or if it needs to be replaced after a fall.

Goggle and Eyeglass Compatibility

The HJC C50 was designed to accommodate a motocross helmet, with space and retention specifically engineered for this purpose. A dedicated groove also allows riders to wear prescription glasses under the helmet--a significant comfort feature for riders who need them.

Care Instructions

After each ride, remove the removable ventilation cover to clean it with lukewarm water and remove any accumulated mud and dust.

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.

Regularly check that the visor is securely fastened and inspect the condition of the double D chin strap to ensure your helmet remains reliable ride after ride.

Frequently Asked Questions About the HJC C50
