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.

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
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
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
Terrible product! I purchased two of these helmets and couldn't be more unhappy with my purchase. The helmet chin curtain flew off on the first ride, the helmet sits very high on your face compared to other helmets and feels unprotected. The wind drag on this helmet is insane and anything above 55mph feels like its trying to pull the helmet off your head. (this happens with vents open or closed) The helmet is terribly noisy, the inner visor does not come down far enough compared to other models and isn't very dark. I find the helmet creates pressure points around the ears partly because it sits so high on your head. I have an old HJC IS-16 that is half the price and twice the helmet... If you are spending this much, go the rest of the way and get a Shoei or the like. If you are a city rider this may be ok for you but for me and my 2014 Hayabusa... this is garbage. May 10, 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
Great lid overall. The only complaint I have with this helmet, is that the chin cover pops off very easily. The little buttons that hold it on are simply not adequate in my opinion. Most of the time I can't get the helmet off without it coming off. Everything else is awesome. Internals are excellent, and the internal visor is very smooth and not too dark. The pinlock system works flawlessly as I would expect. Graphics and finish are very good as well. The vent position provide a positive feel without being too stiff. Not a complaint but simply an observation: YOU WILL NOT WANT THIS HELMET FOR A COMPLETELY UPRIGHT RIDING POSITION. The top vent when sitting bolt upright is extremely loud when open. The air passes over the vent holes when sitting completely upright, instead of flowing into them. It doesn't whistle but it does make it extremely loud. When the vent is closed there is no issue. Definitely a helmet designed for more of a 3/4 position. May 4, 2015

RevZilla Store asked: Why did you choose this?
Christopher Z: Needed a new helmet and was looking for a quieter (which it is compared to the CL-16 [yr2000]) full face with internal visor (which it has). Although, the chin curtain pops off 50% of the time when removing the helmet and when the top vent is open , it gets super loud. Having it partly open is required in temps over 70F, full open around 90F. Apr 19, 2015
