HJC RPHA 90S Modular Helmet Review

We can’t get enough of modular helmets here at Rider. The protection of a full-face helmet combined with the convenience of a flip-up chinbar is really hard to beat. Add in the premium features of a helmet like HJC’s RPHA 90S, and you cover all the bases: safety, comfort, aerodynamics, ventilation, versatility, and ease of use.

Based in Korea, HJC is the world’s largest helmet manufacturer. RPHA, which stands for Revolutionary Performance Helmet Advanced and is pronounced “arfa,” is HJC’s premium line of full-face and modular helmets. The 90S shell is made of HJC’s proprietary, lightweight Premium Integrated Matrix (P.I.M.) Plus that blends carbon and carbon-glass into a hybrid fabric. My medium-sized 90S weighs 3 pounds, 11 ounces, which is comparable to other premium modular helmets we’ve tested.

The interior is 3D-engineered to reduce noise, and combined with the aerodynamic shell, neck roll, and chin curtain, the helmet does a good job of dulling wind noise. The 90S has a plush, removable comfort liner, recessed ear pockets, and channels to accommodate glasses. The anti-scratch faceshield is Pinlock-ready (an anti-fog insert comes in the box), and a sliding lever on the lower left edge of the helmet deploys or retracts the drop-down sunshield. Vents on the chinbar, crown, and rear of the helmet are easy to open or close with gloved hands. Airflow through the helmet is decent but could be better (though that would increase wind noise; I wear earplugs most of the time, so it’s a trade-off I’d be happy to make). Sold separately are Sena-made Smart HJC 20B and 10B Bluetooth communication systems that integrate into a port inside the rear of the helmet.

I’ve been wearing the RPHA 90S for about a month on bikes ranging from a Triumph Speed Triple naked sportbike to the Honda Gold Wing. There is no EPS padding built into the chinbar, but it does latch closed with metal pins and locks securely. The chinbar’s release tab and the center locking mechanism for the faceshield are both easy to find and use on the fly, though with the faceshield cracked open the mechanism ends up in my line of sight. Otherwise, vision is very good through the large eyeport. I appreciate the plush liner for the chinstrap, which secures with a traditional D-ring. The 90S was comfortable, quiet, and user-friendly during 12-hour days in the saddle with highs in the triple digits. Can’t ask for much more than that.

  1. I am sure that at some point Snell will need to bow to the pressure and develop and test modular helmets and assign a safety rating higher than DOT.

  2. With new helmets, the first question I have is: what is the head shape? If it won’t fit, it doesn’t matter. I’d love an alternative to my Arai Signet X in a modular style.
