BMW System 7 EVO vs HJC RPHA 91: the comparison

Are you looking for a practical helmet for your daily rides and want to invest in a modular helmet? Stay right here! We compare these two high-end models for you to help you make the best choice.

BMW System 7 Evo: a premium modular motorcycle helmet from BMW Motorrad

The System 7 Evo modular helmet stands out thanks to its innovative four-hinge design, making it extremely compact even when fully opened. Its shell is made of premium materials, combining 40% carbon fiber, 40% multiaxial fiberglass, and 20% carbon/aramid fiber with epoxy resin, ensuring excellent rigidity while maintaining a lightweight construction.

Thanks to two shell sizes, this helmet offers an optimal morphological fit for every rider. This technical choice ensures superior comfort and a more secure fit, especially for smaller sizes. The inner shell, made of multi-segment expanded polystyrene, offers excellent shock-absorbing properties. Additionally, the integrated MIPS system reduces rotational head movements in the event of an impact, further enhancing rider safety.

The helmet interior has been completely redesigned with new water-repellent materials, ensuring optimal comfort and better moisture management. Ventilation has also been optimized to ensure effective airflow around the head and visor, helping to prevent overheating during hot summer days.

This modular helmet features a double visor consisting of an anti-fog inner visor and an outer visor with a scratch-resistant coating on both sides, ensuring perfect visibility in all conditions. An integrated sun visor, operated via a slider, completes the system to effectively protect against sunlight.

The large rear spoiler improves the helmet's aerodynamics and aeroacoustics, reducing noise and enhancing high-speed stability. The chin bar opens easily via a central button, while the chin strap uses a ratchet closure with integrated neck straps for secure and comfortable fastening.

The visor benefits from optimized mechanics and sealing, ensuring effective protection against bad weather. Finally, the quick and tool-free conversion from full-face to open-face configuration provides great versatility to suit any riding situation.

This modular helmet therefore meets the highest standards in terms of performance, protection, and comfort for motorcyclists.

HJC RPHA 91 Helmet: a practical modular helmet

Designed with PIM EVO (Premium Integrated Matrix) technology, its shell is made from a blend of carbon fiber, aramid, and natural fibers, which gives it excellent impact resistance while remaining very lightweight. This helmet is available from size 54/55 to 62/63, thanks to its four different shell sizes, allowing for an optimal fit to the shape of the head for maximum comfort.

The RPHA 91 is equipped with a removable and washable interior, made from antibacterial fabric that efficiently wicks away sweat. Its ventilation has been optimized with five air inlets and seven exhaust vents to ensure effective airflow and prevent overheating, even on hot days.

This modular helmet features a clear visor with UV protection and anti-scratch treatment. It is also compatible with a Pinlock anti-fog lens, ensuring clear vision in any weather conditions. The micrometric ratchet chinstrap makes it easy to adjust for a quick and secure fit. In addition, it comes with a chin curtain and a nose guard.

In terms of safety, the RPHA 91 complies with ECE 22.06 standards, ensuring maximum protection. Its chin bar locking system is easy to use and provides good acoustic comfort thanks to a tightly sealed base, effectively reducing noise. Finally, this helmet is compatible with Smart HJC 50B and 21B communication systems, allowing for a connected riding experience for modern motorcyclists.

What are the differences between the System 7 Evo and RPHA 91 modular helmets?

Here is a comparison table of the differences between the System 7 Evo and RPHA 91 modular helmets:

The System 7 EVO features an innovative construction with a shell made of 40% carbon fiber, 40% multiaxial fiberglass, and 20% carbon/aramid fiber, combined with epoxy resin. This composition provides exceptional rigidity while maintaining a very light weight, offering optimal comfort even on long rides. In comparison, the RPHA 91 uses PIM EVO technology with a blend of carbon fiber, aramid, and natural fibers, which remains efficient but is less advanced technologically.

A major advantage of the System 7 EVO is the integration of the MIPS (Multi-directional Impact Protection System), which reduces rotational forces on the head in case of impact, significantly increasing rider safety. This feature is not mentioned for the HJC RPHA 91, which puts the System 7 EVO ahead in terms of active protection.

Thanks to its two shell sizes, the System 7 EVO offers a very precise fit, avoiding unnecessary bulk and improving helmet stability. Its interior uses new optimized water-repellent materials for better moisture wicking, while its ventilation is designed to ensure efficient airflow, limiting overheating even in hot weather. The RPHA 91 offers four shell sizes and an antibacterial interior, but comfort and moisture management are slightly less advanced.

The System 7 EVO can be quickly and tool-free converted from a full-face helmet to an open-face helmet, offering ideal versatility for all riding situations. Its dual visor system with an anti-fog inner visor and an anti-scratch outer visor, completed by an integrated adjustable sun visor, ensures optimal visibility in all conditions. The RPHA 91 also offers an internal sun visor and a Pinlock-compatible shield, but the System 7 EVO’s mechanics and sealing are superior.

The large rear spoiler of the System 7 EVO significantly improves aerodynamics and aeroacoustics, reducing noise and ensuring better stability at high speeds. The RPHA 91, for its part, provides good sound insulation.

Which modular helmet should you choose?

The BMW System 7 EVO and the HJC RPHA 91 are two premium modular helmets that stand out for their respective qualities, but the System 7 EVO clearly excels in several key areas, making it a top choice for demanding riders.

While the HJC RPHA 91 is a reliable and efficient modular helmet, the BMW System 7 EVO stands out as the benchmark thanks to its advanced materials, MIPS safety system, superior comfort, optimized aerodynamics, and uncompromising versatility. For riders seeking maximum performance, protection, and style, the System 7 EVO is clearly the helmet of choice.
