HJC RPHA 10 Buzzsaw Helmet 4.8 5 218 218
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
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
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.

Gregory H: The biggest reason was the graphic. Secondly, I know HJC makes a fantastic helmet at a price that doesn't shatter your wallet, just bends it a little. Lastly, I've tried it and several other models and outside of SHARK helmets it had the best interior lining. Oct 7, 2013

Darren P: I purchased the Sena SMH10R Bluetooth/ intercom communicator and installed it in the Buzzsaw Helmet. It works well, the speakers fit fine and the microphone works well! I have a small sized helmet and there is just enough room for the speakers to fit....and I am borderline small/medium in the HJC size chart. The helmet did not come with any specific inserts for speakers, etc Jul 15, 2014

A shopper asked: I have a hjc cl-16. How does this helmet fit as compared to that. I wear a large in the cl-16 model. I was told that this style runs a little smaller in size and I may need a xl due to the close nose fit? Dec 9, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Ahmad S: Yes absolutely, l too usually have a size large for helmets, but was more comfortable with XL on HJC helmet. The main problem lies at the accessory part covering the nose, where size large pushes against my nose at high speeds, whilst is comfortable with XL size. Fortunatel this part is removable so the problem isn't bothering me as much now... Dec 9, 2013
