HJC RPHA ST Helmet - Solid 4.2 5 23 23
Chin courtain ruins it Overall pretty good helmet, good style, comfortable. Wouldn't buy it again for 2 reasons considering it's high price. -Chin courtain locking is horrible, a little touch on it and it flies off, it's a matter of time before I loose it, very rarely I take helmet off without it flying off, and I have to be carefull when putting it on to not slide my chin on it too much otherwise it comes off too. -When locking Visor it makes loud snap noise that hurts you ears January 16, 2016
Great helmet for the price Moving from HJC's CL-17 as my main helmet - the first thing that struck me is how light this helmet feels. The fit was a bit tight, but this is a medium and I'm right between M and L - so I don't think this helmet is sized small. Also, unlike the CL-17, this model's medium and large size share the same shell - so if break-in isn't enough to loosen it up to a comfortable level, I can always swap out the liner and pads. So I decided to keep it and take to the roads, which I did. The vents are a lot easier to find and manipulate than the small ones on the CL-17. The sun visor is easy to operate with a gloved hand also - though not as easily as the integrated sun-shield in the IS-33 (which uses a spring loaded slider along the crown of the head to deploy and a button to retract). The fact that there is included a pin-lock insert in the box is awesome. Easy to install and it just works. No muss no fuss no fog. While this helmet does seem to block out more engine and road noise than the CL-17 there is a lot more wind noise caused by the top vent. When I reached up to the vent with my hand, the noise stopped- but unfortunately the noise was the same whether the vent was closed or open once I took it away. Leaning forward into more of a 3/4 position did lessen the noise, but that's not going to work for me. One of the main reasons I chose this helmet was it's billing as a touring helmet good for 3/4 to upright riding, so the wind-noise is a disappointment. I'd still recommend it though, in every other way, it fits the bill. September 23, 2015
Not bad The helmet is light weight and looks good. I was hoping ventilation would be a little better. Overall a good helmet though. August 31, 2015
Love it. Joe Rocket Prime, Biltwell Bonanza, a cheap Scorpion can't remember the model. This is a list of my other helmets. While I don't feel totally in love with the graphics of this helmet I am in love with everything else it offers. Very lite, great field of view, hi viz naming a few of the things it does exceptionally well. I wanted the Scorpion t1200 but Ben told pinlock was the way too go for true fog proofing. I'm glad I followed his advice. Helmet feels solid and graphic is done well. I'm not an expert, never had a 300+ helmet but it is totally worth every penny. I've put about 250 miles in it so far. September 1, 2015
Worth it Worth every penny. I have the high viz yellow one and it looks sick, fits my head perfectly, im 6'2" 190# and I wear a 7 1/2 hat, i got the Large in this helmet. Ive never worn a super expensive helmet but this one is the lightest ive ever worn. I ride a Honda Grom so i wanted a helmet that was super bright and visible. This def does the trick. I love the pop down sun visor so i dont have to swap out visors or wear sunglasses. You'll get a ton of compliments with this. August 31, 2015
Nice upgrade from my entry-level helmet I'd purchased an HJC CL-16 about two years prior, and am happy that I've upgraded to this RPHA and retire the CL-16 for passengers. I've been commuting and taking a few 2-3 hour rides on the weekend, and overall have been happy. It beats my previous helmet in every category and I enjoy the center latch for the visor and drop down shades. The fit is more snug than I'm used to, but I believe it'll loosen a little once I break in the cheek pads a little bit. Got the blue reflective shield to complete the look - love it. July 8, 2015
Like it better than my old Shoei... Fit is good. Pinlock faceshield works as advertised, as do the integral shades...I threw the chin thingy away... July 6, 2015
Overall a decent helmet I upgraded to the RPHA ST from my IS-16. I'll compare the two now. Pros: I love the included pinlock shield and center locking mechanism! It is more of a round oval which gave me that little bit extra room so my Scala Rider mic is not pressing against my face like with the IS-16. The internal visor works differently than the one in the IS but works effectively and the stock tint is fine for my rides in and out of sun/shade. Cons: I personally don't feel extra air flow over the IS-16. I do get blasted with air with my stock bike screen though so some air comes up into the helmet from there vs through the RPHA's vents. The lever for the visor is smaller and on the side, a bit harder to access with gloves compared with the center lever on the IS-16. I'm sure they moved the lever to try to improve airflow. No cut-outs for comm speakers. Padding feels thinner. Worst aspect for me is the deep groove the forehead pad leaves on my forehead for hours after wearing it. There is a large horizontal seam through the middle of the thin pad. I mostly commute to work and would prefer to look 'normal' soon after the ride. Maybe it is a badge of honor. Overall it is a decent helmet. If I didn't need the more oval shape, though, I would have tried the IS-17 and paid for the pinlock upgrade which would have saved a few dollars. June 22, 2015
