HJC RPHA ST Helmet - Solid 4.1 5 8 8
Nice light helmet Big improvement over my HJC IS-16 in all areas. Absolutely zero fog on the vizor here in cold MN. May 18, 2015
This helmet is a great value I purchased this helmet as I needed to replace my 5 year old helmet. The HJC ST fits very nice, not too snug and not loose. The vents are very effective at keeping my head cool on the highway. The helmet is a little louder than my previous helmet but its worth it as the additional vents are nice. Rode 150 miles so far and I am happy with this helmet. May 11, 2015
Couldn't be happier for the quality and price If you're looking for a mid-level cruiser/touring helmet without spending the money on a getting a low-level Shoei or Arai this helmet is great. It's lightweight, comfortable and provides good ventilation. I think its quiet, but I'm also coming from a non-DOT half helmet. I think it might be more of a round head fit, whereas my head is slightly longer/more oval shaped. Pair it up with a dark-smoke windscreen and you're cruisin' in style. April 27, 2015
Good Helmet for the Price This helmet is an upgrade from the HJC CL-Max II. I wanted to go with a full face rather than a modular to get a quieter helmet. It turns out this helmet is not that much quieter. Only slightly so I still need to wear ear plugs. The helmet does require some break in time but was only a couple of days and now feels really good and slightly on the tight side. The venting is good, especially the top and exhaust vents. I can really feel the air flow on the top of my head. The chin vent doesn't seem to move much air however and I'm thankful for the pinlock shield (which works really well). As another reviewer noted, my biggest and only complaint is the chin curtain. I think this is a really poor design. It is difficult to install and my thumbs were sore from pushing in the pins/buttons. It has also popped off when I either put on or take off the helmet. Big annoyance and I curse it every time it comes off. Good thing the chin curtain isn't why I purchased the helmet.Overall I really like the looks, comfort, pinlock, and drop down visor. I've tried the Shoei GT-Air and I think the HJC is a great alternative to the GT-Air and definitely at a better price point. I'm happy with this helmet. March 13, 2015
A solid lid I've had this helmet for a few weeks now and I only have a few nitpicks. 1st, the chin curtain was a royal pain to get in and have it stay there. Though I have gotten to the point where I can get it in every time, it seems like it doesn't take much for it to come out. Hopefully it doesn't pop off while going down the road. 2nd, the flip down visor fogs up really quick on cold days though I suppose that is expected. I plan to treat it with some anti-fog. 3rd, I wish they had more options for graphics (I ended up just going with matte black). Last I'll just make a note that this isn't the quietest helmet out there by any stretch but it is much quieter than the Scorpion I had previously. Other than those bits it's a great helmet for the money. It's a sharp lid, it's relatively quiet, it's comfortable, it's light, the sun visor works great (when it's not fogged up), it comes with a pinlock and locking shield with solid detents. Again, it's a great lid overall and I would recommend it to anybody looking for the same features I was as this has them all for a good price. November 20, 2014
Great Bang for the Buck! For the money you really can't ask for any better. Purchased this to upgrade from my intro level Bell Arrow, and it's much more aerodynamic and quiet. Also wanted the internal sun visor so I wouldn't have to switch out the lenses on longer rides and it works like a charm. I was looking at this helmet and the Shoei GT-Air because it's hard to find a high quality, truly functional full face with the internal sun visor in the lower price ranges and now that I've put some miles on it I'm happy with my choice and the amount of money I was able to save running with the HJC as opposed to the much more expensive Shoei. No complaints! November 4, 2014
Boom, here's your bang for the buck! I purchased this helmet based on certain criteria but mostly due to my desire for an internal sun visor. After considering the Shark Speed-R, Nolan N86 and Shoei GT Air, I ultimately went with HJC's RPHA ST. My decision was based on a review from a UK supplier called Two Wheel Centre (see their YouTube video). The RPHA ST is also the test-winner of the new MOTORRAD Magazine helmet test, in front of such prestigious models like the Schuberth S2, X-lite X-702 GT and Shark Speed-R. I've ridden nearly 400 miles with it now and can say that it's a very comfortable and well-made helmet. My only gripe would be that there is significant wind noise while at freeway speed, even with earplugs. I'm assuming that the noise is coming from the unusual side air foils, which help vent the helmet very well. The external shield is high-quality and crystal-clear and the internal sun visor is sufficiently smoked for me. All in all it's a great helmet, despite the wind noise, considering it's a couple of hundred less than its comparable alternatives. Once ordered, they had it to me the very next day... thanks for the great customer service Revzilla! October 25, 2014
Lightweight Helmet With Great Features I purchased this helmet as a replacement for a Shark Evoline - I know that they're very different. I was focused on getting a substantially lighter helmet that would still have the drop down sun visor - or some similar sun blocking feature - and an effective means of preventing fogging. The sunvisor isn't as dark as I would like, but it does remove the glare well and allows it be deployed a little later into the evening than normal. The mechanism is solid and the coverage is great! The pinlock system is AMAZING! I've tried to make this system fog and I can't. In fact, the only fog that forms is on the sunvisor, not the main shield. Watch the instructional video on how to install the pinlock system and it should be fairly easy. Other good features are that the shield engagement and lock is positive and easy to operate. The vents are effective and also easy to operate. The shield disengagement mechanism is also very user friendly. It also worked well for me with a Sena SMH10R Intercom. There was plenty of room for the speakers. The only negatives I have are somewhat subjective. The rubatone matte black gets oily really easily when handled but that's to be expected. When I fitted my intercom system into the helmet, a couple of the snaps for the liner on the helmet side seem to be coming loose from taking the liner in and out. This is the only quality escape I've noticed though. When I first tried the helmet on, there were a couple pressure points at the rear #where the snaps are) and a little pressure at the front) probably because my head isn't as round as I thought. After wearing it for a couple hours in the house, leaving it over night then trying it the next day, I found that it already started to break-in. It seems like the helmet has a considerable amount of break-in give. Overall I couldn't find another helment with these features in this price range. I'm very impressed. October 24, 2014

A shopper asked: I'm trying to decide between the RPHA ST and the less expensive IS-17. One of the main complaints from reviewers of the IS-17 is that the internal sun shield isn't dark enough. Have you found the shield on the RPHA ST to be adequate? I wear prescription glasses/sunglasses and I'm trying to eliminate the switching.

More generally, if anyone has cross-shopped the IS-17 and RPHA ST, I'd be interested to hear your thoughts. Thanks!
