    Superb Helmet, MUST BUY FOR THE MONEY - 2y4life   Recommended by Reviewer: Yes
    Pros: [None]
    Cons: [None]

    Rating- Using your basic 1-10 scale or my own MMAPro Wrestling scale.1 Deplorabe. They couldn't pay me enough to wear it regularly unless it was in the 3 figure range lol, then I'd consider it. A Kenneth Allen3 Pretty bad. I would not buy it, again, unless I was paid, I will skip on this helmetfeature. A Shungo Oyama5 Average, maybe I'd buy it again and maybe I wouldn't depending on the circumstances. I think we all know what a 5 is or what average means. A Phil Baroni.7 Pretty good, or above average. I would likely buy it again or the feature is something I could live with and not complain much. A Heath Herringgate keeper.10 Cream of the crop, the holy grail. The Royce Gracie of the 90s or Fedor of the earlymid 2000s or GSP of the late 2000s and early 2010s. Simply put, cannot be defeated.PriceThe RPHA-10 is now available at a few places for 199 on closeout which is ridiculous and a deciding factor in my purchase. This helmet, when it first came out, had an MSRP 359-554 depending on the graphics with the Ben Spies and Jorge Lorenzo Replicas being the most expensive one. Most places are still selling them at 300 for just the solids, ahem RevZilla. So to be able to nab a supposedly great helmet at 50 off was just too good of a deal to let it pass by. 9.510 or Anderson Silva- Those PEDs helped a bitSafetyIsn't this the reason we get these things Well, it's a day old and only 65miles on the noggin so I'll just get to the stats and go to the next area of interest. SNELL M2010 and DOT certified. 810 simply because it is not ECE R22.05 or Robbie LawlerFitComfortThe helmet is obviously a bit more of a race fit helmet but I assume most of us have worn an race fit helmet before. Snug but man this one fit like a glove. Within seconds, I didn't even notice I was wearing. I would say this helmet fits more of a neutral shape, some say round but it is not round like the CL-17. Definitely more neutral or maybe even slightly on the more narrow ovalintermediate oval than a true round. Love the fit, the liner felt better than I remember from trying it on a few months ago the liner is very plush and just has a great quality feel to it. Feels like a soft pillow all around my head the moment I put it on and then it disappears completely, figuratively speaking. I tried on my CL-17 and the Multitec and there was a big change. It also feels better than my old RF-1100 as well.8.510 or Chris WiedmanFace ShiedVisionThe eye port here, vertically is just average if you look at just the dimensions of the. The width of the shield is above average. With that said, there's a difference when you put it on and actually look through the eye port. Unlike my modular Shoei and the CL-17, I can actually see more vertically in this helmet than my previous 4 helmets RF-1100 included. I'm not sure because I measured the vertical visor size and it's basically the same as my CL-17 but once it's on, I can barely see the top of the visor. It's really in the way the helmet sits or wraps around my head. It allows me to see more than my other three helmets. The width is exceptional as well. I can see my nearly my entire peripheral vision with little hindrance. I almost have to turn my head to see the sides of my visor, or the edge of the helmet.Outside of what I consider outstanding vision, it comes with a pinlock ready shield AND a free clear pinlock insert. No need to spend another 30 or more for an insert although a light smoke would've been my preference. 9.510 or Prime motivated BJ PennVentilationAirflowAgain, I wish I had my RF-1100 so I could compare but I don't and so this is where it gets a bit washy. The ventilation and airflow on this is excellent, much better than the Multitec and CL-17. Immediately I could feel the airflow from the top vent, free air just coming in. I want to say the top ventilation was, at the very least, as great as the 1100 but I'm going off what I remember from over a year ago. My head feels massive air coming in and I mean that by helmet standards.With that said, the lower vent feels very substandard. I haven't been on the highway much so maybe at high speeds for a distance and my mind will change but as it stands, very substandard. I felt the 1100 had more air flowing through the chin vent and the CL-17 DOES have a bit more airflow as well. Because of that, the rating will go down quite a bit. If it was just based on the top vent, it'd be a 9. All things considered, still more airflow than the CL-17 but not quite as much as the RF-1100 and slightly above average. 710 or Frank TriggNoise LevelOddly enough, maybe it's the shape of my head but this helmet is noisier than the RF-1100 and my CL-17. It's about the same as the modular Multitec. I was a bit disappointed and this is one area that I don't think will get better with time. Even though it has a great chin curtain, the air doesn't seem to seal around my neck well and that's where the air enters. I've taken my hand and put it around my neck like a single hand chock and it's eerily silent and I don't feel like my neck is that thin so I'm not sure why. This is the one true knock on this helmet and will receive my lowest rating although I wear ear plugs if I ride longer than 10 mins on the highway. 510 or Shonie CarterWeightThis is where this helmet really excels and could be seen in the comfortfit section there's a reason it's so comfortable and while the liner plays a huge role, the weight or lack thereof is equally important. As I mentioned earlier, immediately after putting it on and feeling that soft plush feel, the helmet sort of just vanishes. The vision is great, liner wonderful, and helmet so light that I literally didn't feel the helmet. I must say that I've have never owned a CF helmet so I am not sure how that would feel and I know that would likely be lighter but I looked at the stats this morning and sure enough, I was not deceived by my senses or that new gear feeling. My XL came in at 1576grams3.47lbs. While I don't have my RF-1100, I do have the stats available online. The RF-1100 in XL is 1746grams3.85lbs. The HJC CL-17 in XL came in at 1754grams3.87lbs. While the numbers seem small, I really do feel a HUGE difference. 910 or Chuck LiddellOverall I was hesitant to get another HJC due to the CL-17 feeling like just a decent helmet but nothing special like my two previous Shoei helmets. This RPHA-10 changed my mind completely. I honestly don't believe I could get anything at 199 and get all the things I got here. Overall, I would have to give the helmet 910 or Johnny HendricksIf you want a helmet for 200 or less and not worry about it feeling less than premium, this is definitely the one to get. I will update this in two weeks and see how things go.PS, my heart feels like this helmet is a 9.5 mainly due to how great of a deal it was but my head stabilizes things and tells me it's an 8 right now after 65 miles and two days.

    great helmet - kyledukes   PA Recommended by Reviewer: Yes
    Pros: lightweight, comfortable, ventilation
    Cons: none.

    Got this as my first helmet. I went to a few stores and tried on helmets so I already knew my size. This helmet feels much better than its Competitor helmets, icon and scorpion. I tried alot helmets on. The anti fog feature is nice and the ventilation is cool.

    Nice Helmet - MJK   CO Recommended by Reviewer: Yes
    Pros: Light, ventilated, excellent value on closeout
    Cons: [None]

    I have no complaints. It is nice to have a light helmet and one that exceeds minimum safety standards. Ventilation is better than average and helmet mates well with my goggles. Fit is perfect for me in medium which matches with fit chart. I'd highly recommend this helmet.

    Light weight - Slonol   CA Recommended by Reviewer: Yes
    Pros: Light weight
    Cons: Tight fit on the side of forehead

    To Replace 10 year old Arai RX7, and this is lighter and as aerodynamic as the more expensive helmet. Snell approved. I have a very round head and The HJC is more oval shape than I like. I hope it's broken in more as I ride with it more.

    Velo rider - Jim A., Tucson, AZ   AZ Recommended by Reviewer: Yes
    Pros: Fit matches size. Face shield comes down lower. Strap long enough for my 3 chins
    Cons: Side protection a little skimpy.

    Over all, very good. I especially like the longer face shield. Less buffeting.

    Helmet - Brett McGinnis   NC Recommended by Reviewer: Yes
    Pros: Great visibility, not to heavy and looks great

    HJC RPHA X - Ride Michigan   Recommended by Reviewer: Yes
    Pros: lightweight, comfortable, good ventilation,
    Cons: none

    I used to race off-road and have owned several top of the line helmets. I've been out of dirt biking for several years and just got back in to it this year. I purchased the RPHA X Tempest, wore it during an enduro and kinda forgot about the helmet. I guess you could say it is comfortable if you don't think about it during your ride. The helmet fits well, is lightweight, goggles fit nicely, ventilation is good, cant't beat the price, no complaints Thankfully, haven't tested the crashworthiness of it....yet

    HJC RPHA-10 - Rich L.   MN Recommended by Reviewer: Yes
    Pros: Light, quiet, comfortable, noticeable airflow.
    Cons: Shield whistle when fully open, could use stronger detents for the shield.

    As mentioned in other reviews, this helmet does tend to run a little on the small side. I normally wear a XL and according to HJC's sizing chart for THIS helmet, there is a separate chart for the RPHA series I would need a 2XL to fit my melon. Sure enough, the 2XL fits me like every other XL I've owned. It's a racing inspired helmet, it's supposed to be snug, but if you order the size you normally wear, it will likely be uncomfortably tight. With that out of the way, it's a great helmet and I love it. With the shield down and latched it is the smoothest, quietest helmet I've had. I wear glasses and I typically ride with the shield cracked open slightly or fully upright. In this position I get a mildly annoying wind whistle noticeable with earplugs in and the shield won't stay up and will drop once roadwind speed is high enough. Slightly stronger detents for the screen would be helpful here. The center latch is great easy access with either thumb. Glassessunglasses access is good, no interference from temple padding.So far I've only ridden with it in the heat of summer and the airflow is great. You can feel it pulling heat off the top of your head. I love the CAGE graphic sporty looking without being overly busy or gaudy. Paint quality appears near flawless and it looks to have a decent clearcoat over everything. It should hold up well.

    Pros: Helmet fits great. Perfect size.

    quality, quiet - larry   CA Recommended by Reviewer: Yes
    Pros: great fit, quality and reasonably quiet
    Cons: not quiet enough

    fabulous snug fit makes the RPHA 10 the best HJC helmet yet and the best fitting helmet I have ever worn which includes owning the A brand and the S brand. While wind noise is reduced, it is still not eliminated. For the money, there may be nothing better,

    NICE - marco   Recommended by Reviewer: Yes
    Pros: light weight, air flow, comfort
    Cons: scratches easily,

    I have owned several helmets over the years for racing an open cockpit car. I used an older one when I first got my new bike. The first ride with my FG-17 was a whole new level of comfort. Less wind noise, less lift when you turn your head at speed and GREAT air flow inside the helmet for comfort and anti fogging. I would and will buy another one for my wife to ride with me. They fit snug at first but loosen up over time.

    A Must Have - CBR 1000RR-OKC,OK   OK Recommended by Reviewer: Yes
    Pros: Very Light Weight, Great Ventilation,True Soft Fit,Perfect Vision Capability,No Shimmy at High Speeds
    Cons: None

    This is a true must have for your collection if you can only buy one helmet, buy this one. If your worried about size I'm 23 right above brow line and a Large fit me perfect anything above 23 14 you better move up to a XL, one other thing the manufacturer size specs I believe are a little more accurate so check HJC before buying it from here HJC has really stepped up to the big leagues with the RPHA-10 perfect for the track or taking it on a road trip, 5 stars in each category CR-OKC

    Awesome Helmet - Debbie   MT Recommended by Reviewer: Yes

    HJC RPHA-10 Evoke Helmet - Rich B   Recommended by Reviewer: Yes
    Pros: well constructed helmet comfortable helmet looks outstanding comes with the pinlock system
    Cons: none that I can think of

    Let me start off by saying this is one comfortable helmet. I appreciate the fact that the helmet comes with the pin lock system which costs 26.99 if purchased separately. The graphics on this lid are top notch. I was concerned about the visor and the locking system. After a few times of locking down the shield while driving solved any issues I could have had. You can lock the latch with one hand with gloves on. To completely remove the shield is a breeze also. I like the fact that I can remove most of the padding inside the helmet for cleaning. You simply drop them in the washing machine and let them air dry before reinstalling them. The helmet is Snell and DOT approved which means a lot to me. If there was a shortfall I would say say it is in the ventilation system. I live in Florida and of course it gets hot in the summer. There seems to be no big difference if I open the two top vents all the way as opposed to a lower setting.

    HJC CL-33 Helmets - tdr   UT Recommended by Reviewer: Yes
    Pros: [None]
    Cons: [None]

    Having a large 7 58 and somewhat oval shaped head, I was pleasantly surprised that the XL fit just like it was supposed to - a real worry when buying hatshelmets online. I have never had this type of helmet before full face shield. it is a nice combination between the full face and the skid lid I normally choose from wearing.

    good helmet - Crabsmith   PA Recommended by Reviewer: Yes
    Pros: light weight, comfortable, nice interior, shield latch, cooling features
    Cons: more wind noise than expected

    I wanted a very light weight helmet that was also of good quality. This helmet fits the need very well.The Large fits comfortably, even though I have a narrow is slightly tighter than a normal HJC Large, but I believe this is due to it being designed as a racing helmet. Also, I like the latch mechanism on the face shield, it creates a good seal. The cooling features also seem to work pretty well. The only down-side is that it could be more quiet...not that it's bad...but in this price range I expected less wind noise. Overall a great helmet though.

    Great Helmet - Bret   MA Recommended by Reviewer: Yes
    Pros: Very Light, well ventilated and comfortable
    Cons: Sizing if you are on the edge

    This is a very nice helmet especially for the money. It is as comfortable as my Aria and so far seems as well put together. I am on the lower end of an xl from their sizing chart but is seems like it may end up a little to big after it packs out. Overall though my next helmet will be another one of these just maybe in a large.

    Nice Helmet - Gaston Gagne   NC Recommended by Reviewer: Yes
    Pros: Light weight and comfortable
    Cons: [None]

    I haven't had much of a chance to wear this helmet as it is winter. However, the helmet fits as my previous HJC helmets, so no surprises there. It is significantly lighter than my previous HJC helmets. CompAcc got it to my door in a timely manner.

    Great deal at close out price - Brian   Recommended by Reviewer: Yes
    Pros: Scratch resistant face-shields that are replaceable, generous padding, good value
    Cons: Matte black looks very easy to scratch, HJC logo is on when matte is not supposed to have

    I have to agree with the previous review that the chin strap should be longer and I wouldn't say I have a thick neck. I'll use my new helmet for the first time tomorrow and will update after that experience. I can say that buying from Competition Accessories was a great experience. Product was shown not in stock and still delivered in less than a week. Will purchase again from them for sure.

    Force Helmet - Belkerx3   MO Recommended by Reviewer: Yes
    Pros: Beautiful helmet
    Cons: Fits very tight

    I waited nearly 3 months to receive my new Force helmet. This is a very nice helmet. Fit and finish is very good. I had some trouble fitting my J&M speakers into the shallow speaker pockets. I typically wear an XL HJC helmet. This one is so tight I thought I got the wrong size. I cannot hardly fit my sunglasses due to the tightness. Hopefully it will break in soon and loosen up. It is very tight I do love the high viz color. I would buy another one, it's that good.

    Red, White, and Blue - Rachel   Recommended by Reviewer: Yes
    Pros: Great Style, Light-weight, Excellent Value, Very Comfortable, Pinlock Included, etc.
    Cons: Blue is NOT like photo

    Love the RPHA-10 helmet - see all the Pros. I usually wear top-of-the-line ARAI, but heard about this helmet, tried it on, and I was sold But, it should say Red, White, and Blue-ish Black. The Blue is not bright like the picture, but a deep and dark blue-ish black. I was extremely disappointed when I took the helmet out of the bag and will be taking it back. P.S. there is an R at the forehead, not HJC I liked this. I would recommend the HJC RPHA-10, but not the Zappy color.

    Beautiful Helmet - Big-D   AZ Recommended by Reviewer: Yes
    Pros: Color Scheme is awesome, extremely light weight, very comfortable, allows for perfect fit and visability
    Cons: Sizes run Small

    I first purchased this helmet in a Large. I have several other helmets in various brands and they are all in Large and fit very nicely. However, this helmet in a Large was way too tight, so much so I bought another in a X-Large. Now it fits perfect so I can wear this helmet for really long period with no pain or discomfort from it being too tight. And it is not too big either, the fit is perfect.I would have rated this helmet a 5-Star except because I had worn the first helmet in Large, I was not able to return it and had to purchase a second in XL. Ultimately costing me twice as much. However, I like this helmet so much, it was worth it to me to make the double purchase. The other helmet in Large I gave it to a very good friend that it fit just right.The construction of this helmet meets or exceeds the much higher priced helmets in the 600 price range

    Beautiful Helmet - Big-D   AZ Recommended by Reviewer: Yes
    Pros: Super Light Weight, Great Graphics, Superb Construction, Comfortable once on
    Cons: Size runs a little small, really right putting over head.

    Although my helmet size has always run border line between a Large & Extra-Large, it seems every helmet I have ever bought, the large has always fit just right the way a helmet should fit, while I have bought two helmets in Extra-Large only to have them move around too much, being told they were too big for me.After receiving this HJC RPHA-X Factor helmet in Large, I couldn't wait to slip it on. When first putting it on, it almost wouldn't go over my head. Realizing its new and may need to adjust to my head shape, I forced it over my head. Once on, it fit snug, but comfortable. It doesn't feel overly tight, nor do I think it will make my head sore. The only problem at this point is the initial fitting over my head. It seems the opening is really tight, almost as though it has the opening on a Medium and the shell is a large.I will try it for several rides and see how it feels once broke in. I love the helmet. It is one of the finest looking helmets I've ever owned and I have 11 helmets from several manufacturers.

    The sizing information is provided by the manufacturer and does not guarantee a perfect fit. However, we are happy to assist you with any needed exchanges.

    Note: the RPHA-Max seems to run a little smaller due to the thick padding and smaller overall shell design. Most size exchanges have been to up a size. So if you are on the fence. We recommend thinking about going up a size to start. However, please keep in mind the padding will break in some and a helmet that is a little tight vs. too loose for safety.
