HJC RPHA 10 Buzzsaw Helmet 4.8 5 210 210
Great helmet I originally had this helmet in black so I knew getting this one would fit right. I have a weird shaped head where only HJC and Arai's fit. Its a great helmet and fits great. My only complaint is that its a bit loud. Sometimes I close the vents to cut down on the noise level. My friend borrowed my helmet and said it was super loud compared to a different one he was using. I've only been able to fit into these Rpha 10's so I don't have anything else to compare them to. Overall great helmet, looks great and the fit is comfortable. Super easy to switch out the shields to a darker one for daytime use. October 5, 2015
Excellent value Love the helmet - clean simple design and good features. The 3 vents provide some good venting. Face shields are relatively inexpensive and very easy to swap out. The interior cushioning easily comes out for cleaning/washing. I would guess the sizing runs a bit small - I needed a large and I don't really have a 'large' head by comparison. September 21, 2015
best helmet I've ever owned This helmet is extraordinary and given the price, it makes you wonder why most helmets are not manufactured this way. The inner liner feels smooth against the skin and airflow feels amazing when all vents are open! The noise level in my opinion is a medium so you still need to wear ear plugs. If HJC can make this helmet quieter it will be just as good if not better than any high end Shoei or Arai. Overall this is the best helmet I've ever owned and will most likely buy another when the time comes. September 21, 2015
Comfortable Safety...wish it had better "racing" visibility I've gone thru 2 of these helmets. This one and the Graffitti. The comfort outways the faults. First the bad, when I'm gridding up and the 3 sign is out, I really like to put the visor up. However, the 2 board always seems early and the 1 is also rushed and I need to get the visor down and snapped quick. This visor is a little hard to snap shut with my race gloves. An average problem, basically I like to stick my neck way out lining up a turn. The top of the helmet is a little lower than I wish it was. Basically Looking left and right is useless during a race. You're not worried about traffic you always look forward or "up". Up being that you're hanging off the side of the bike and craning your neck "up" to look forward. The top of the visor opening could be a little more to make that easier. It's hard on my neck. The good, comfort, comfort, comfort. This helmet rocks. The great, I've gone thru two of these because me head has hit the pavement twice. The first time was upwards of 140mph and I barely felt it. My arm felt like the hand of God reached down and slapped me into the track but my head barely registered the fall. The second time I didn't feel a thing. Thru the few faults this helmet rocks simply for comfort and protecting my dome. Love it. A similar fall in my "helmet not to be mentioned" and I saw stars. September 14, 2015
A great buy with decent features. I wanted full face helmet for an up coming trip, so I decided on the RPHA 10 based on price and overall reviews. Since it was a closeout, I assume because of the color, it was about $100 off the regular sale price. My head size was right on the border of a medium-large at 22 7/8" so I opted for the large. I have never been able to wear a medium in a full face helmet. I think it was a good choice. It still fits fairly snug after breaking it in so I'm glad I went with the large. It's about average on noise but it is very light in weight. I had hope it would be a little quieter but still a good value with the include pin lock shield. September 14, 2015
Just what I wanted I have had this helmet for a few months now, and can finally tackle a review. It is great. The visor seals well, the helmet vents good, and it's a lot quieter than my old HJC FS-6s helmet. I would not hesitate to recommend this helmet or purchase again if I neeeded to. September 9, 2015
Great Value, especially at sale price I bought the rpha 10 evoke in black at a sale price of $240. I was on the face between this and a Bell RS1 that I got to try on in a store. With the arpha being priced for so much less, I decided to give it a try and i'm glad I did. I've purchased 2 other full face helmets before this one. A GMAX GM78 (decent for an entry-level helmet) and a Lazer Monaco Pure Glass modular helmet. (Very nice for touring or group rides) this is my basis of comparison when it comes to airflow, noise level and comfort. This helmet has a very comfortable interior, small profile, snug fit that still feels good even after a few hours, and a small first detent for around town. The latch on the front works well but I usually ride with it unsecured to allow the shield to stay fog-free. I have a 23 inch head measurement and a large fit perfectly. I also have an intermediate oval head shape. The rpha is quieter than both of my other helmets but I still need earplugs for longer rides. As far as style goes the evoke pictures didn't impress me online but it does look pretty good in person. The graphic is definitely gray and silver even though it can look gold in videos and some pictures. I bought the dark smoke shield to go with it and it looks pretty bada$$. are thinking about getting this helmet I strongly recommend it, especially at the sale price. September 5, 2015
Outstanding look This helmet looks and feels awesome. Interior is high quality and easily removable. July 17, 2015

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

Ahmad S: I am not sure if its called plus version, but l can assure you it has all the things you mentioned above including pinlock, chin curtain, different pins & the windbreaker.. It is also very comfortable, light and highly effective even at extreme speeds of about 180 mph = 290 km/h.. I recommend it Jan 10, 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
