I can seal the helmet well by closing both front and rear vents and minimize cold air intrusion. I’m torn between another Qwest, a Shoei RF-1200 (review), and the HJC RPHA 11 Pro. They are the emergency pull out cheek pads. We’ve noticed this before on other helmets with fiberglass or composite shells, so it could be a combination of the shell material along with the EPS, the lining and the construction. The helmet meets the DOT standard in the U.S.A. and ECE 22.05 in Europe. We initially assumed that the RPHA 11 Pro would have a “Slightly Narrow” internal shape (according to the webBikeWorld Motorcycle Helmet FAQ), which is typical for a “racing” oriented sport helmet. Sounds crazy, but that’s the situation with way too many motorcycle helmets. Note that all of the helmets reviewed on webBikeWorld have been weighed and the weights are available on the wBW Motorcycle Helmet Weights page. There are fewer choices for solid colors; just black, white and the “Semi-Flat Titanium” shown here. But the composite helmet shell seems to have a slight quirk. But I’ll agree that the RPHA is a step above other HJC models on fit, finish, quality, and features. Large single slider opens the chin vent with a secondary slider on the inside. It’s comfortable, although the padding feels a little thinner than the DS-X1, but this may vary, depending on the head size vs. shell size. The sizing does seem small, however, by about one full size. Or, you can control the amount by moving the inner vent slider to your desired position. You’re In The Right Place. Good face shield design. It’s very rare indeed when there’s so much ventilation that we actually have to close the top vents and with the RPHA 11 Pro, that’s definitely the case (at least in our cool winter weather). Regarding the pricing, the RPHA 11 Pro has a list price of about twice the average HJC helmet, but half of what you’d pay for a Shoei, Arai, Schuberth, etc. In-depth guides to help riders understand what to look for, how to weigh options and make good buying decisions. Top vents also, it’s winter here and we’ve been wearing the helmet in 40 degree weather and it has such good ventilation that the top vents have to be closed or only opened to one notch on the roller. Whether or how long they’ll remain in the lineup is unknown; possibly only until the existing stock is gone, although a new RPHA ST colorway was recently announced, which indicates continued support for the “10” lineup. The RPHA 11 Pro has a double-D ring chin strap attachment system with a plastic snap to hold the excess and adequate chin strap padding. A lot of the negatives aren’t even a factor in racing. Note also that perceived noise levels will vary, depending on the individual. Reviewing motorcycle products for over 20 years. In general, the RPHA 11 Pro is quiet enough and perhaps we can rate it as average to slightly better than average when riding a “naked” or unfaired bike. As a result of our experience we have quit using the RPHA helmets and gone to other brand and model with more room in the front of the helmets. See the webBikeWorld Site Info page. An owner-installable chin curtain is also included; it’s very nicely made but be sure to follow the instructions explicitly when you install it. The noise isn’t unbearable by any means, but it is something to be aware of. My only hesitation is cold weather riding. Excellent selection There's a problem loading this menu right now. The RPS 10 was known as the RPHA 10 in Europe and shortly thereafter, HJC switched from RPS to RPHA in the U.S.A. also. Do you do 35mm cheekpads that I can buy and use on this helmet? Rick’s Reply: Actually, I think the RPHA 11 Pro has very good sealing in the vents. See also the chart that lists the helmets by weight and shape on the wBW Motorcycle Helmet Shapes page. Given how close the chin bar is to the face it’s not surprising now. The features cater to sport riders with an enlarged eye port for an increased view in a tucked position and an outstanding airflow ventilation system. Note that you will need the anti-fog insert however in cold weather, because the standard face shield is apparently untreated, so when it’s locked shut, it will fog. Note that we always wear high-quality, correctly fitted disposable ear plugs when reviewing motorcycle helmets, so your results will certainly vary from ours if you don’t.

This wasn’t expected and it does work, making it easy to slide a pair of sunglasses or eyeglasses inside the helmet. At that time, even the HJC reps at the show couldn’t explain what the new RPS helmet line was all about and how it would fit into the HJC lineup. Outstanding build quality. The RPS 10 was known as the RPHA 10 in Europe and shortly thereafter, HJC switched from RPS to RPHA in the U.S.A. also.
