Is the HJC RPHA 11 a Quiet Helmet?

 

Perhaps, you have been smitten by the appearance and outstanding features of the HJC RPHA 11 helmet. And you are considering buying it besides a modular motorcycle helmet. But you aren’t so sure about its performance, especially the nose level.

 

Therefore, how does the noise level of HJC RPHA 11 compare to a flip-up helmet? Is it so noisy, quiet, or moderate? Let’s comb through its features and find out how noisy or quiet it is.

 

What Type is the HJC RPHA 11 Helmet?

 

The RPHA 11 is a full-face helmet. However, it has a provision for pulling the visor up or down minus the chin bar. And with the shield open, you enjoy fresh air and an unobstructed view. 

 

Its overall design makes it ideal for sports performance. Below are other vital features of the RPHA 11 helmet:

 

ECE 22.05 Certified

 

Its overall design conforms to or supersedes the ECE 22.05 standards. Specifically, the ECE certification concentrates on its wind penetration ability, structural integrity of the chin bar, and energy attenuation. 

 

And according to SHARP’s rating, the HJC RPHA 11 has a score of 3/5. According to SHARP’s testing the helmet’s safety protection should have been better on either side of the helmet. That explains the average score of 3/5.

Reinforced PIM+ Shell

 

As the sports helmet, the RPHA features a shell that boasts PIM+ technology. The helmet mixes the carbon hybrid fabric and carbon to produce a shell that has an extra shock resistance ability. However, it does that and still maintains a lighter weight. 

 

Wind Tunnel Tested Aerodynamic Shape. 

 

HJC designs and tests the helmet in its wind tunnel to ensure it presents an aerodynamic shape that meets the industry standards. The wind tunnel testing checks on the helmet's wind penetration, noise level, and ventilation. 

 

Multi-Cool Removable Liner

 

The RPHA 11 sports helmet has a removable liner that wicks away the moisture to keep the rider cool. Further, the liner has an antibacterial ability and ensures a fresh feeling helmet interior. 

 

Advanced Channeling Ventilation System

 

Ventilation is a critical factor in sports helmets. HJC understands that and uses the advanced channeling ventilation technology in the RPHA 11. The numerous vents at the chin, just above the eyebrows level and forehead maintain adequate air circulation. 

 

The RPHA 11 features removable cheek pads and toolless visor replacement. 

 

5 Year Warranty

 

The high-quality design of the helmet allows the manufacturer to provide a 5-year warranty against the product. Alternatively, the warranty also spreads to 7 years from the date of manufacture. In comparison to the warranty period the company offers on even the best modular motorcycle helmet, RPHA series helmets attract higher warranty period.

Which Features Does the HJC RPHA 11 Have that Influence Its Noise Level?

 

Usually, the noise level of a helmet depends on the following factors:

 

Its Aerodynamic Performance

 

Poor sealings, for example, from below the neck region, ventilation, and a tiny gap between the shield and the helmet body

 

Empty Speaker Pockets 

 

As per the HJC RPHA 11, these are the feature that influences its noise performance;

 

Multiple Vents

 

The design of this helmet is such that it has vents at the eye browse level, forehead, and chin region. These openings let in air and thus contribute to the noticeable noise level. 

 

Flip-Up Visor

 

Although it’s a full-face helmet, RPHA has a shield that opens up. Hence in the open-face position, it allows plenty of air to rush into the helmet. 

 

Chin Curtain

 

To minimize noise level, HJC incorporates a chin curtain in the helmet. The helmet cuts down the amount of air rushing in through that vent.

 

Improved Aerodynamic Performance

 

As most users agree, the RPHA has an improved aerodynamic shape that gives it less wind resistance. Thus, as you turn your head, you experience less wind opposition.  

 

How to Make the HJC RPHA 11 Quieter 

 

From the features highlighted, the RPHA 11 helmet is neither too loud nor quiet. It has a moderate noise level. However, you can further bring down its noise level by practicing the following:

 

Adjusting the Vents

 

The chin and forehead vent on the RPHA 11 helmet are adjustable. Thus, you can cut down its noise level by balancing between keeping you ventilated and not letting in excess air. 

 

Tight Visor Seal

 

Poor sealing of the visor contributes to high noise levels. Therefore, before beginning your ride, close down the visor tightly. Fortunately, HJC provides a lock to keep the visor secure at high-speed rides. In addition, ensure the chin curtain is in its rightful place.

 

Using Earplugs

 

Another alternative to managing the noise level of the helmet is putting on a pair of earplugs. Doing so shields off a considerable amount of noise and lets you concentrate on what matters most; riding.

 

Wearing Balaclava

 

Some volume of air also rushes into the helmet via the base of the hood. A brilliant way to manage the problem is wearing a balaclava, face mask, or wind blocker. Such devices cover the base of the helmet and, therefore, block unwanted air from seeping into the helmet. 

 

Getting the right fitting HJC RPHA 11 Helmet

 

The HJC RPHA 11 helmet is moderately noisy. But if you settle on a hood that is a little big for your head, the noise worsens and might become intolerable. A better option is choosing the right fitting lid with the maximum snug fit you can tolerate. 

 

Verdict on the Noise Level of HJC RPHA 11

 

Having looked into the top features of the RPHA 11, we conclude that the full-face helmet has a moderate degree of noise. However, if you want the HJC helmet that has better noise management, then the RPHA 11 Pro version fits the bill.   

 

But if you already have the RPHA 11, there are a few tricks for improving its noise performance. Always ride the helmet with the visor locked down. Adjust the vents to minimize the volume of air rushing into the helmet. 

 

Consider investing in balaclava, face musk, or wind blocker. Alternatively, you can wear earplugs to keep off the noise. You can further visit the Helmet Gurus for other tricks of minimizing noise level in a motorcycle helmet.
