HJC RPHA ST Rugal Helmet 4.3 5 31 31
Good airflow I have a RPHA ST Zaytun in Hi-viz/black (size XL). It fits well, I purchased thicker cheek pads as I have a thin face. The helmet does rather well in that wind resistance is minimized compared to my older helmet. Shoulder checks on the highway/interstate require much less effort. The airflow is fantastic but the wind noise, a bit on the noisy side of things. The interior is plush and comfortable. I managed to fit my Fusar F7 headset into this helmet. It is a bit of a snug fit, but it is not tight, nor uncomfortable. The sun visor moves rather quickly - snapping in and out of place with the operation of a lever on the left of the helmet. This is something that whacks into my nose when I engage it and I feel the design can be improved upon. The matt paint on this helmet looks incredible. July 20, 2016
Great Helmet I was looking at a lot of the cheaper alternatives to this helmet but quickly realized it was worth the money. I love this helmet, it fits great is quiet, but haven't worn it going over 60 mph yet. great air flow. I would recommend this to others. June 26, 2016
Great helmet for the price With this helmet you're getting fantastic value at a much lower price than you'd expect. If Arai or Shoei look out of your budget, HJC's RPHA helmets might be a great option for you. April 19, 2016
LUV the HJC RPHA ST RPHA helmets are advertised to provide superior protection which is what matters most to me in a helmet. The flip down visor was worth the additional cost over other RPHA helmets, particularly useful as I ride with glasses to correct for nearsightedness and the visor covers my glasses (and looks very cool). Shield and visor go up and down easily. Shield is easy to remove and replace. Good air flow through the helmet. RPHA ST is light and super comfortable for a full face helmet. I tried a Shoei GT Air before buying the HJC RPHA ST and like the HJC RPHA ST MUCH better; I think my head is a bit too round for the Shoei and it gave me a headache during the trial wear. I like the way the RPHA looks. May 11, 2016
Best HJC Purchase Could not believe the comfort once I tried it on in the store. I tried on some Icon Helmets but they are more of a oval fit. This helmet is snug and right away I knew it was going to break in perfect. May 4, 2016
Loving this helmet I was looking for an upgrade from my CL-17. I decided to stick with HJC since I know them to fit my more rounded head pretty well, and I'm not disappointed. The fit is even better than my old helmet even though this one is still new. The seal around the visor is noticeably quieter than what I am used to. Vents are very easy to use as well. Only problem I had this this helmet was installing my Sena 3S-W. There just wasn't a way that I was going to get the speakers to fit by my ears comfortable without cutting into the foam where I needed the speakers to go. April 28, 2016
Good buy for the money Went from a Shoei to this HJC and I really like the fit and it seems quieter to me April 22, 2016
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
