Thanks for the feedback! For our road test we mainly focus on the temperature difference that the helmets are able to achieve. So, though the two helmets were tested at different outside temperatures, we were still hoping the Hornet ADV would have provided a stronger level of ventilation. In addition to this, we have tested numerous helmets in similar 30 degree weather, including the Schuberth C4 Pro and AGV Sportmodular, and have found that they were able to stay cool, being one degree less than the outside. What are your thoughts on the two helmets?

Completely agree. I get the delta calculations but there is a third variable - riders head and heat coming from it. You now have 3 temps to calculate deltas from and it's just not correct way to do it.

Thanks for the feedback! What did you think of the road test for these helmets?

Champion Helmets loved the Road test, the attention to detail is amazing. Thanks to you guys, I bought the Arai and love it

Thanks, we're happy to hear we were able to help!

Our pleasure! For ventilation, we'd definitely go with the Arai Tour X4 over the Shoei Hornet ADV. In addition to this, the Arai will also come with a few extra interior features that will improve the Tour X4's comfort, which round it out as an all around excellent adventure helmet. Thanks for the comment! Besides the ventilation, what did you think of how the two helmets compared?

@@Championhelmets thank you once again, that's another valid point for Tour X4. I did not have the chance to test them but besides ventilation I like Hornet's features: possibility to remove the peak without the tools, possibility to remove / replace the visor without removing the peak and that I can use gogles just with the visor on the upright position. When it comes to the looks that's definitelly point for Arai but this is just my personal preference.

@@szymonchalupka Thanks for the reply! The Hornet ADV certainly does offer a lot of those great features, which only makes the ventilation issue even more of a shame since it is well designed in most other aspects. If you find you have any further questions, we're always happy to help

Thanks for the feedback! The Shoei will certainly do well if you're looking to keep warm. Did you find any of the road test results for the helmet surprising?

Champion Helmets A bit surprised the shoei was significantly warmer, But to be honest I didn’t really have any presumptions before watching the video. Love that you guys are recording the sound level in helmets!

Hey there! Ideally, we do try to test the helmets out in the same conditions, and we keep other factors the same as much as possible to still keep the absolute difference relevant. Would you go for the Arai or the Shoei?

Champion Helmets - I’m still on the fence. I think it will come down to fit ultimately.

@@spiceweasel945 That's fair, and is the best way to ensure the helmet's comfort and safety. If you have any questions down the line, let us know and we'd be happy to help

Spice Weasel 100% . Both are top of the food chain premium helmets. Given that, fitment is most important

Yes, both are just different names for the same helmet. In Europe, it's the Tour X4 while in the US market it's the XD4

Thanks for the feedback! We are hoping to include this more, but are currently looking at the best way to go about it fairly. What did you think of the two helmets we tested out?

Thanks for the feedback! Would you go for the Shoei or the Arai?

The peak mounting on the Hornet was much easier than the Tour X4 since it uses twist screws that you can use with your fingers and you don't need to remove the visor either

Hey there, thanks for the question! The peak on the Hornet is much easier to mount since it uses twist screws that you can operate with your hands and it operates independently of the visor. For the Tour X4 you would need a screw driver as well as the extra side panels for visor only riding and peak riding.

Both helmets are designed to fit communication systems. To date, we have not heard any particular complaints about the fitment of speakers or Cardo systems in either helmet. Thanks for the question! What are your thoughts on the helmets we tested out?

@@Championhelmets after watching your review, I think I will pick Arai, to replace my old trusty Schuberth E1. Thanks for your very informative video. Keep up the good work...👍🏼👍🏼

@@galuhrichata6148 Based on our road test results, we would also lean towards the Arai. Thanks for the reply! If you find you have any further questions, we're always happy to help

When looking at the ventilation of a helmet, we always compare them based on their temperature difference to the outside. We have tested out numerous helmets in both warmer and cooler conditions and still gotten the same strong results as we found with the Arai. In colder conditions, we have also tested out helmets and found that they don't perform as well, as with the Hornet ADV. However, the point on the Arai vents is a good one since there are two always open chin vents, which may let some water in while all the Hornet's vents are adjustable. Thanks for the comment!

6 year of using Rx-7 no problem with ventilation parts/plastics. But we had to change some ventilation int/exh parts for our customers. Weight - all ece-22.06 helmets (if they have) are now 6-12% heavier except Arai, which stayed the same. So weight is not an issue anymore 🥰

It shows the difference between inside and outside temperature, makes total sense to me. And it's a road test not a science article, chill the f out.

Thanks for the feedback! We do our best to try and always bring the facts. Especially since its so difficult to tell how a helmet performs on the road. What did you think of how the two helmets compared?

If it is possible to get a proper fit after changing the liner of the Tour X4, then that would be the option we would go for. As was shown in our test, the Shoei Hornet did not offer a high level of ventilation with a 6 degree difference. When we tested out the Airoh Commander (the results of which will be released soon) we also found it had a poor ventilation result with a 12 degree difference to the outside. Both the Shoei and the Airoh seem to suffer from not having large or enough brow vents to adequately bring air into the helmet. Thanks for the question! Besides airflow, what are your thoughts on the two helmets?

And finally I ordered the arai tour x4. Luckily I have a friend who show me all the specifics about the arai and I am very impressed. For the last 3 years I used to ride with a shoei nxr and I was a big fun of shoei. Now that I know some more things about how arai make its helmets I changed my mind. Thanks a lot for your help!!

@@christopherp.5201 With such a strong level of features and the time Arai have put into the helmet, it's certainly a formidable option compared to the competition. We're always impressed with how Arai manage to pack so much into just the interior alone. Thanks for the reply! If you find you have any further questions, we're always happy to help

It is possible that helmets perform differently on other bikes due to different fitments, riding positions, and fairings. Nonetheless, the data we collect is always the data that we show. We do our best to bring fair tests for all helmets, which means using the same setup between helmets and checking the average airspeed to ensure a proper comparison. Both the Arai and Shoei were tested with airspeeds ranging between 110-120 km/h, and both showed an average result of 102dB on our meter, which has also proved about standard for the majority of adventure helmets that we've tested so far.

We do our best to make sure that our road tests are controlled by using the same bike, sensors, speed, highway, and positioning. We were hoping for a better result from the Hornet ADV as well, however the data we presented is the data we recorded. Thanks for the comment!

For our road tests we try to keep them as comparable as possible so the material, weight, and visor categories are independent of our rider. For ventilation, we place the thermometer between the liner and the helmet's EPS and for noise we do the same but place the microphone in the ear of the helmet so we try to reduce the impact of fitment. Though it is true that different people will experience the helmet a bit differently depending on the fit. Would you go for the Arai Tour X4 or the Shoei Hornet ADV?

Champion Helmets Thank you. Makes sense. Both are top of the food chain. I like the Shoei. Appreciate the feedback.

Thanks for the suggestion! We'll add the helmet to our review list, though we unfortunately don't sell it. How do you think it would compare with the Shoei and the Arai?

I've not tried the BMW helmet yet. From what I've heard around its a pretty good comfortable helmet. I think the testing you guys are doing will help a lot of us thinking of something else then the Aria or Shoei

@@stefangerber4415 Thanks, we're happy to help out with our tests!

Thanks again

Thanks for the suggestion! We'll look into adding the AX-9 to our calendar. Of the Tour X4 and the Hornet ADV, which would you go for?

@@Championhelmets I have a Shoei head, Arai its an awesome helmet, but between those, I prefer the one from Eitaro

@@motoexplora6235 A decent choice, if there's anything else we can help with, just let us know

@@Championhelmets can u tell me why Schuberth helmets are so over rated? i had a C3 Pro, bought the C4 and never understood why its so popular

@@motoexplora6235 It's mainly because they perform very well, when we took it out on our road test, it turned out to be one of our top modular helmets in terms of ventilation, noise isolation, and comfort, which also made it a good helmet in terms of value for money, and we found this hard to argue with. While there were issues with the C4 including ventilation and visor problems, these have been solved with the addition of the C4 Pro. While sometimes things may be a bit overhyped or related to personal preferences, the C4 Pro is a great helmet and performs on par with other helmets like the Shoei Neotec 2. At the moment we haven't had a chance to road test more of Schuberth's line, so we have yet to see how the rest of their helmets perform

Yes

Thanks for the question! If you prefer to wear goggles, then the Shoei Hornet ADV may be a better choice since it has a groove for the goggle strap in the back and the visor lifts higher so you can fit goggles easier without having to remove the visor.

Thanks for the suggestion! Though we unfortunately don't stock Nexx helmets, and likely won't be able to get our hands on them, we do have the Klim Krios Pro scheduled in for a road test. What did you think of the two helmets' performance?

@@Championhelmets Of the nexx xwed 2 they say that it is one of the best in everything, the only negative would be the anchoring system of the viewfinder apparently it is very weak. Of the klim krios pro they say that it is safer thanks to the koroyd. I would like to know how quiet, aerodynamic, sail effect, pros and cons, I would like to know your opinion, thank you!

That's fair enough. Just looking at the helmet, the Krios Pro does seem like it is definitely able to stand on its own in the premium end of the market alongside the Arai and Shoei. Especially with the Koroyd offering such a light weight with a high level of safety. Though we haven't taken it out on our road test yet, it is amazing in terms of weight and the chin strap is excellent since it is so easy to use. However, the interior is not as plush as some of the competition and there seem to be irregularities in the carbon fiber weave, but we'll have a better idea of the helmet once we've taken it out. If you have any further questions, we're always happy to help

Thanks for the comment! If you're planning to mount a GoPro on the chin bar, the Hornet would definitely be easier since it's smoother and you wouldn't lose as much of the chin ventilation as on the Tour X4. Did any of the results surprise you?

The GoPro mount is the big deal breaker for me. It was strange that the black Arai helmet stayed cooler inside than the white Shoei.

The temperature difference was likely in the Arai's favor since it had many very large vents that were based on the same system as the RX-7V. So not only was the chin vent larger, but there was a lot more in terms of forehead ventilation and exhaust vents
