HJC C91 - Plain
The HJC C91 is a cost-effective flip-up helmet, featuring an advanced polycarbonate shell, ventilation system and internal sun shield.
As the successor to the popular HJC IS-MAX 2, the C91 is designed to meet ECE 22.05 standards, with a high level of impact absorption and structural integrity. The lightweight advanced, polycarbonate shell provides a superior fit and comfort using sophisticated CAD technology, with smooth lines for improved aerodynamic performance.
The chin bar can be raised using a discreet button underneath the centre of the bar, allowing to convert the helmet into an open face.
The HJC's advanced channelling ventilation system (ACS) provides a high level of airflow from front to back to flush heat and humidity, with reduced wind noise. The HJ-17 visor offers substantial peripheral vision with an anti-fog and anti-scratch coating, a user-friendly visor locking system, and an internal drop-down sun shield to block the sunlight.
The C91 is designed to seamlessly integrate the Smart HJC 20B and 10B Bluetooth intercom systems, co-developed with Sena for HJC helmets (sold separately). The removable supercool interior is designed to keep your head fresh and moisture-free throughout your ride, with moisture-wicking and anti-bacterial properties. The C91 is fastened with a simple and secure ratchet strap.

When you order a helmet online we can only accept a return when the helmet is unworn and HAS NOT been used out on the motorcycle. When you receive your helmet, please try it on for around an hour in the comfort of your home, do not go out on the motorcycle with it. If the helmet is too loose or is too tight, get in touch and we will help to provide a return.
Circumference Measurement: Wrap a measuring tape around your head starting from the centre of your forehead. Measure about an inch above your eyebrows and hold tape comfortably snug. Take the length and complete again for good measure. Use the largest of the two readings.
