HJC RPHA 10 Combust Helmet 4.8 5 218 218
This is a very good helmet at a very good price. I have used this helmet the HJC RPHA 10 Evoke for about three months. the helmet has very good air flow for the hot summer months, and for the cooler months like now with the vents closed the helmet is air tight and very warm. the helmet is light and does not move around in the wind even when you are behind a truck on the highway, and that makes it a whole lot easier on the neck on a long ride. All in all the HJC RPHA 10 is a high quality helmet and I would highly recommend this helmet to anyone needing a new one!! November 17, 2015
A Great Helmet for a Great Price This is a great quality helmet that is DOT and SNELL certified for a great price. It flows air well through the mouth and top vents. The liner in super comfortable and easily removable for washing which is a plus. The shield has a great seal which keeps out water when getting caught in the rain. One issue the helmet has is fogging, but that is only if you do not install the pinlock insert. The helmet feels secure at high speeds and there is minimal buffeting. The best part is that the black/orange buzzsaw graphic matches my KTM perfectly! October 28, 2015
Lightweight with good protection This helmet is comfortable, lightweight and runs a tiny bit small for a large. It took a little break in time before it fit my large head well. It comes with a pinlock shield and an insert, and once that was installed, there was no issue with fogging. I gave mine the roughest test, which was a 130 mph crash. I went down hard but the helmet did it's job and I did not have a concussion. I've just purchased another one to replace the rashed helmet. I've never liked a helmet enough to do that in my 30 years of riding. October 26, 2015
Great Lid Fit for me --- right on. Style --- right on. Value compared to the high enders --- way up there. I've only had two issues, one the shield mechanism failed and could not be repaired in the field so I had to use duct tape to keep it on until I could get to a shop. Even there, they had to pull a part from an existing helmet to fix this one. When I got home ZLA sold me a repair kit for the future. The other issue...noise. If the top vents are open, this helmet roars. If they are closed, it roars less but then it gets hot. Be careful about pressure on the adjustable wheels for the vent, they are not strong and fail easily with even slight pressure. BTW, the metallic silver shield, the expensive one, lasts about one hour before the coating fails. October 26, 2015
Great Product First helmet, did run a bit smaller compared other helmets I have tried on. I would think normally i would be a large but medium fit a bit more snug. i went with a medium and glad i did. As it started breaking in it feels really comfortable. The helmet is also very light, i almost forgot i have it on. Definitely worth the money. October 19, 2015
Amazing value! Sure Arai and Shoei make great helmets but who wants to pay for a label? Super god looking, good air flow, stable at speed and a price other companies can't touch save maybe Scorpion. The pinloc insert makes the shield essentially fog proof. I personally love the graphics and I can wear it all day long since it's so light. Save you money and get an RPHA10! You won't regret it. Thanks Revzilla for the price and fast delivery. October 12, 2015
A good helmet that many will be happy with This helmet is great, it looks good, fits well, and has a few nice features. Pros: + Two open/close vents on top of head to allow air to flow, they allow for partial open to allow "some" air to get through. + Comes with pins on the shield for insertable anti fog plates - my purchase came with an anti-fog insert, I put it in approx 3 weeks after getting the helmet, and wow, I wish I put it in right away. It doesn't fog even if I intentionally blow on the inside of the shield. + Padded, high quality straps + Removable padding to facilitate washing pads + Fairly good price Note that I have no idea how well this helmet does what it is designed for: Protecting your head in a collision/crash. I hope that it stays that way, but so far, I believe I can trust this helmet would keep me safe if so needed. October 12, 2015
Great alternative to Shoei or Arai! The good: Graphics and finish are excellent, exactly what you'd expect from a "high end" lid. Fit is good, for comparison I usually wore a Medium in Shoei's and Arai's, and a medium is what I have in the RPHA-10. Comfort liner is soft, and doesn't irritate my skin anywhere. A big plus for one with irritable skin. The bad: Airflow could be better, and the shield tends to whistle at times. The anit-fog insert is a kind of a pain to install/uninstall. And when it is installed it tends to make contact with the shield here and there, creating an effect similar to when tint bubbles up in auto glass. Not very pleasing. So, I just use an anti-fog spray, which seems to work just fine as long as it's applied often. Overall, I'm very happy with this helmet. HJC just needs to do some fine tuning for the next generation.

A shopper asked: My wife measures my head at 23 inches. The chart says I should be in a size large, the top range being 23 1/4. Do the charts run true, that the L won't be too small? I appreciate Revzilla's generous return policy, but I live in Ontario, and am concerned about border fees if I have to return something and then receive a replacement.
I will be riding upright, i.e. cruiser style, (I'm a new rider) and am wondering if this is the right helmet for that type of riding, or is there a more appropriate make/model? Any additional comments about the Combust itself would also be appreciated. :-)

Gary T: I don't recall how large my head is, but I ordered based on their chart and found it to be accurate and a good fit. Of course, the shape of your head can also affect how well it fits, in addition to just the size. Fortunately, I was able to try one on at a local motorcycle shop to ensure a good fit before ordering, but if you can't do that, I think their sizing runs pretty true.

I ride a Star Raider cruiser and I like the full face helmet for winter (I live in Arizona) or long distance riding. I also have a Scorpion EXO-C110 half helmet that I wear when it is hotter or I'm going shorter distances. However, keep in mind that even when it's hot, the full face helmet is much quieter and getting hit with bugs in the face at 70 MPH doesn't really feel good wearing a half helmet, but I do like having the flexibility of both options.

Overall, I've been happy with the helmet. I've had it for two years and it's held up well. I've used the pinlock, and in my experience, it isn't perfect, but is certainly better than nothing.

Sebastien P: I bought that helmet a couple of years ago and I'm very pleased with it.
I'm 23 1/4 and the size L is perfect for me. The internal shape is neutral to slight narrow.
What I like:
- the external shape of the shell
- the quality of paint and awesome design
- relatively quiet
- the shield mechanism and central locking
- the soft and cool liner
- the Pin-Lock
- the very light weight
- the overall quality
- the price

What I'm not crazy about:
- the ventilation specially at the chin. Works better on 3/4 position than upright

Would I buy it again? Absolutely.

Hope this helps.

S I: Hi, my head size is 23", I own a HJC RPHA 10 Combust Helmet large, it fits
just perfect, also my head shape is round and so it's the helmet, probably that explains why, I also own helmets like shoei, scorpion exxo and others, this is a really comfortable helmet.
I ride a Suzuki Hayabusa witch is a sport touring bike so I have to lean a little to the front and the helmet feels just fine. It is a beautiful looking helmet and light weight too.
You won't regret buying this helmet.
Good luck

William R L: I found the chart to be right on. I ordered the size HJC recommended and it fit perfectly. It's very light, easy to put on and take off and very comfortable as well.Not to mention it's awesome to look at. I ride a Goldwing and feel the helmet is perfect for my riding style. It's very quiet, with very little wind noise, even on the highway. May 21, 2015

Shawn H: Sizing runs true. I ride mostly upright and the helmet performs great. Live the liner, very cool and comfertable. Shield works great, I like the center lock and if it's not locked it is cracked just enough to prevent fogging. Haven't used the included pin lock yet. Very happy with the helmet May 21, 2015
