HJC RPHA 91 - Review & Road-Test - ChampionHelmets.com 

Thank you for your comment, we appreciate it! If you have any further questions or feedback please let us know! What did you think, besides the noise, of the RPHA 91?

@@Championhelmets it'll be used for electric unicycle riding so the weight is a bit high - especially for off-road. So I wonder if HJC will have a Carbon version later.

Thank you, we appreciate your comment! The Neotec 2 performed better on the visor, ventilation and comfort compared to the RPHA 91, and the RPHA 91 did better on material and noise. You can choose the helmet based on your personal preferences.

What did you end up going with? I'm currently looking more art the neotec

That's what I noticed too. On the video of the RPHA91 the wind speed is 105 to 115 for 95db. On the video of the schubert s3 the wind speed in 120 to 125 for 100db. On the video of the LS2 Storm 2 the wind is 140 km/h for 105db... A 30km/h difference in wind speed could explain a 10db noise difference between the LS2 Storm 2 and the RPHA91. They claim the wind speed is 120km/h on both but I really doubt it is. Is the RPHA91 really the most quiet helmet on the market on did it just benefited from good conditions and back wind on the test ? Unless ChampionHelmets bring proof about a scientific method they used to make their results reproductible independently of the weather conditions I think those measurements needs to be taken with a pinch of salt as the conditions of the day could easily introduce an margin error that could put a helmet from great to bad, or the opposite, on their rating.

Thank you Soulia! Shipping to the US takes 3 to 5 business days with express shipping and 4 to 6 weeks with regular shipping. If you have any further questions please let us know!

Thank you Viktor, the helmet indeed has brow vents, which can be opend and closed as well.

@@Championhelmets Thank you very much! It would be very interesting to find out how well they perform, and where exactly do they conduct the airflow inside the helmet! This helmet is very appealing overall!

Thank you! The outer shell sizes are XS-S, M-L and XL-XXL

Thank you Tarik! The RPHA 91 is 2 decibel quieter compared to the RPHA 90S Carbon.

@@Championhelmets do you know if the optics on the visor and sun shield are better on the 90 than 90s? Is the fit different? What is the weight difference?

I'm née to HJC, having my RPHA 70 for around 25 hours each week, after 6 months, no sore spots.

Hello Balazs, Thank you for your question. The biggest difference between the 50B and the 21B is the Intercom Pairing & Voice Command!

+40k kms with the RPHA 90S (probably 2/3 of that under rain) and never had a single drop inside the visor!

Hello Martijn, this is the most quitest helmet we ever tested! 95 decibel is indeed incredibly quiet.

​@Championhelmets how can it be when you reviewed the schuberth c3 which came in the 80's decibels?

@@problemslayer3538that’s what the producer measures in their test conditions The C5 here scored equally to the Neotec 3 at 98db Then, any rider/bike/windshield/ riding position combination is gonna affect your perceived noise, consider that I found my Arai Tour X-4 without the visor and with padded speakers as silent as this Neotec 3 one, because my head conformation blocks almost all the noise even without dedicated flaps

We've got a seperate review on the Carbon version, watch it here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GSWAinfKMbE.htmlsi=xsbKZZGiU4h5Ovq9

Thank you! The biggest difference between the 90s carbon and RPHA 91 is the noise. The RPHA 91 is 2 decibel quieter than the RPHA 90S Carbon.

Coming very soon, keep your notifications on!

Wondering the exact same.

I also have this question.

There could be a Carbon Version in the future just like they did with the RPHA 90S, but we don't know when!

Hello Jorge, the helmet will be available from January 18!

@@Championhelmets thats not true! Fuck HJC

Same here

You ride with the helmet open at such speeds?

English. But It's not his first language as you can hear, but I can clearly understand what he is saying.

Hi Chris, the RPHA 91 is indeed heavier than the RPHA 90s Carbon, this is due to the fact that is isn't made from carbon and has the 22.06 certification! (22.06 certfied helmets are on the heavier side compared to 22.05 certified helmets)

​@@ChampionhelmetsWe should be asking why 22.6? Where's the data showing fatalities from 22.5....thanks to the EU we now have heavier and bigger shells in helmets to accommodate the excess crap....Did we, as riders ask for this? Of course not, just more crap forced upon us...ride free lol.
