HJC RPHA 10 Combust Helmet 4.8 5 140 140
Great Helmet for the price This helmet was well recommended for all of owners that I met. I bought it and it's really a great helmet, I have a old Arai and I don´t have any complain about the quality. The airflow is really nice too. April 13, 2015
Hellz yeah. Really happy with this purchase. All around amazing lid. VERY light, but still DOT, and SNELL certified. Great field of vision. Fit is spot on, and I do mean spot on. Its going to be snug, but thats what it should be. very quite, and the aerodynamics are well done (no lifting off your head at speed). The venting is alright, and Im sure there are other helmets that are a bit better, but I doubt they are quite so track ready in design. Easy off screen with pinlocks is great, and the lock is simple but as stated in vid feels solid. The ratchet knob vents on top are ok. I think the 6 position rotation is more of a novelty, and would have preferred a more simple mechanism, but it doesnt detract from the helmet. If youre looking for an aggressive, safe, all around well made helmet under $500 then this is it. April 7, 2015
Incredible helmet compaires to much more expensive ones. I've owned several Arai helmets over they years, but finding new ones that fit has been challenging. The RPHA-10 fits me like the old Arai Quantum e, the HJC with it's light weight shell and excellent airflow actually edges out the Arai for me. Once you add in price, HJC has a real contender in the RPHA helmet line. If I had to give any bad points to it, it would be for the lack of preplanning in the helmet series for limited Bluetooth comms. I went ahead and used a soldering iron to open a hole in the neck roll to run the wires effectively. And speaker placement behind the cheek pads could use better design. I placed mine behind the pad, which works well, and keeps the speakers off the ears. All said, as long as HJC produces the RPHA-10 I will be buying them. March 31, 2015
Great upgrade from older helmets I have a few 10 year old helmets - HJC and Shoei - that have served me well but it was time for an upgrade. I found the RPHA 10 Cage on clearance for $250 and bought it. The finish and quality is a significant step up from the older helmets I have. This is the first helmet I have ever worn that I can feel positive air flow onto the top of my head through the vents. I guess helmet venting has come a long way and this one directs nice cool air onto the top of my head. However, there is a trade off to this, which is that when I'm riding in colder temps of 30-40 degrees, I can still feel very cold air leaking onto the top of my head even with the vents closed. Even so, I still love this helmet! April 14, 2015
GREAT HELMET I was very happy with the helmet. I am now on my second RPHA 10. ( red and white, and now the lorenzo ghost ). I couldnt be happier with it and I love the pin lock option. No fog in my vision is amazing being in high humidity area. Have recommended this helmet to many people. April 13, 2015
Great Mid Tier Helmet Wanted an upgrade my from KBC, but wasn't quite ready for the jump to SHOEI or Arai. The HJC RPHA-10 was the perfect choice. Same quality as the top line helmets, yet a fraction of the cost. Definitely recommend this helmet. April 13, 2015
I love this helmet I purchased this helmet after trying several different ones. This one has that race feel and superior comfort. No noise other than the sound of your bike revving at high rpms. As for wind there was no resistance while riding at higher speeds almost as if it was cutting the air as you rode. So after long periods your neck didn't feel wore out. Also the interior of the helmet almost feels like silk on your skin compare to cheaper helmets. I am extremely pleased with this helmet and honestly would recommend this to anyone. April 10, 2015
Overall good helmet for the price. I like the features of the helmet, everything is easy to operate. Very comfortable material. It seems true to size, but does have a smaller light weight feel. The cheek pads seem like they will need to be broken in, they are the only part of the helmet that seems a little tight at first. This helmet replaced my Shoei RF800 that I've had for the past 15 years. April 6, 2015
