If possible, I would browse at one of the stores and try a few on to see which fits the head best and feels most comfortable. The Shoei GT air 2 was probable the best fit for my head shape out of the helmets I tried on, Shoei, HJC & AGV.
Round head - Arai. Int oval head - Shoei. Ruroc - forget it when compared to the other two brands. I own 22 helmets I am sad to say. I own all of these three brands and for me, it would be between Arai and Shoei depending on your head shape...
Just one point to add to the comments. Based on the homologations/regulations Arai X concept is ECE 22.05 and Ruroc Atlas 4.0 is ECE 22.06. So we can say Atlas 4.0 is safer than X-Concept...
That is a great question, what would be classic but perform well. Personally I use a K6 but, I think you should watch the reviews on Champion helmets as this was a big factor for my decision. Hope that helped.
Ever notice how high-quality audio products don't need marketing? Sennheiser HD800 series are all hand-made in Germany, as Aria and Shoei are also hand-made in Japan. Or go watch Isle of Mann TT and see what helmets they are using. I dont think you will find rurock used. In fact, there is not enough money in the world for me to use rurock as a daily driver. Look, i have seen many racers/riders use AGV, even them I stay away. They are great Italians made, I think. It's all 100% safety or nothing for the brain. No shortcuts. Rurock, to me, is like only fans 304s. Looks great, but it's not something you take home to and introduce to your parents.
Hello there, I’ve recently purchased an HJC RPHA 71. Fit and finish are superb and it is lightweight. The included pin lock 120 is a value bonus. Ventilation is excellent on top, the front vent is a bit too ineffective when it’s hot. Only gripe is it’s too pretty in pearl white; I only use it when I want to look cool for my girl.
Always an interesting question. I did the same thing about a year ago and ended up with a Kabuto RT33. The Kabuto has been a very comfortable helmet and I would buy it again. One of the reasons that I chose it, was that it was FIM approved. This seemed like possibly a safer option. On your list the Arai is also FIM approved I believe. As for plain white or graphics, I chose graphics as I feel that anything that may catch a drivers eye is a good thing.
Strangely enough, I got the Shoei GT Air2 but I kind of like the Bell from a price point. Bell is still racing impact spec but fell out of popularity, so the price is 30% cheaper just because it isn't popular. It might not suit style as a personal helmet but I would definitely look at it for an occasional passenger. There is not a lot of design angle in the shell, it is designed in the same shape it always is, as rounded off as it can be so that there are no wrenching zones to the neck after the head impact.
AGV is the only brand I'll wear. K6 is fantastically light and unfortunately for the rest of my body, I've tested its quality. I owe AGV my life. The moment that insurance check cleared, I bought the exact same helmet.
Glad to hear you survived a potential disaster Nathan and the K6 kept you here! I hope you're well and I'll check out the K6. Thanks for the recommendation!
It would be nice to get helmets for evaluation. I like full helmets the best once I get them on but the comfort of modulars and the ease of putting them on and off with glasses makes them appealing to me. I'm forcing myself to wear full helmets as much as possible and I'll likely be purchasing a new one soon myself. I agree with your reasoning on the full helmets but the improvement of modular helmet safety is closing the gap towards the full face.....I hope.🙂
Thanks Jerry! I actually put the modern day modular helmets in the same category as the full face helmet. Once that lid is locked down I reckon they're pretty safe.
I have the Arai Concept X and it is my favourite of all my helmets. It fits well and is great at its sizing. Sizing wise my Shoe is tight, Harley helmet spot on, Scorpion helmet is large, and Bell Bullit helmet which is also tight, like the Shoe. I love a quiet helmet too and surprisingly my Arai Concept X is very quiet, and probably pips my Shoe for quietness. However, with the external sun shade I have on it, it will sometimes make a slight hiss in a heavy wind. But that is rare, and takes 30 seconds to detach.
Whatever fits best, naturally. Personally, I am heavily opposed to buying a "brand" in this situation, instead of an item. I fell for a brand name twice already. But while shopping for a spare helmet to give to a passenger from time to time, I discovered that a certain company from Spain makes extremely affordable, yet almost perfect fitting helmets for my head. Now I find myself using an $80 helmet almost exclusively, while a couple of $4-500 pots sit collecting dust. As for noise, again from personal experience, the quieter the helmet, the less ventilation it normally has. Earplugs and the lightest, reasonably priced and certified helmet all day, all the way. $800 is an overkill for my taste. I would rather buy several helmets for different times of year (warmer-colder periods).
I have an Arai. The helmet is extremely comfortable, extremely safe/trusted, and you can got to a gear shop to try it on. Until I see ruroc helmets being used in professional racing and videos of people putting the helmet through safety tests, I will never consider ruroc.
Get the ruroc, the atlas 4.0 is amazing. Really like the fidlock tech. I use the shockwave and that’s been great for communication. The 4.0 is miles away from when they started. I owned the 2.0 and that one I can’t recommend so much. But the 4.0 fixed all the problems I had
I’ve got a few Rurocs myself. Absolutely love mine. The A4 is amazing. There was a gent that did a review and comparison on a few of these companies… I believe his name was chopperfett? If I can find it I will post as and edit.
I don't know if it's very useful because people won't have tested the 2 helmets and everyone will say that their choice is the best without knowing if this is really the case. Not to mention the fact that each brand more or less adapts to a given face shape. The problem with ruroc helmets is that you can't try them on in stores...
Hello mate, I´d say white is the best option in order to be seen and thus have a plus safety wise. I dont own one but if you are willing to spend that much money on a helmet you might also consider looking into buying a klim krios pro. You can take the shield off and I heard they are super comfortable and lightweight. There is also a youtube video of the klim vs either a shoei or arai, I cant remember, its been a while.
The Ruroc is carbon fiber whilst I believe the Arai is not. I love both, but for that type of bike I would want a much wider and full vision. Personally I would go Ruroc.
Hi mate, you decide on the helmet yet? I got my Ruroc 2 days ago. It's perfect! Good fit, nice on noise reduction, and looks very good. I am a M usually and so I got the M/L and it is fine.
I know RUROC feels new because they’ve only entered the motorcycle market in the last few years. But they’ve been making helmets for high speed snow sports, bob sled, speed skiing etc for ages. Those sports have similar crash speeds as motorcycling. RUROC also has ECE and DOT. I know Arai has snell, but it doesn’t mean it’s safer. Ultimately, RUROC provides as much protection as Arai, it’ll all depend on what’s more comfortable to you. PS RUROC looks better 😉
I ride with a Bell Race Star Flex on my Indians(FTR & Sport Chief). I refuse to ever own a Ruroc because of their past shady marketing schemes(fake it til you make it). Ruroc are supposedly better now but just on ethics alone I'd steer clear. Bell on the other hand is extremely high quality & the quietest helmet I've owned & I decat & straight pipe my V-Twins. The transitional lense is a must so there's never a need to swap for day/night or clunky drop shades. So if Bell isn't an option for you this time definitely just go with the Arai or Shoei, with a decorative print ofc ;)
The most important thing is fit, and maybe neither will fit. Personal genetics really. Ruroc seems to be mainly marketing from influencers. The R3 had a poor rep with Ruroc banning forum users for poor reviews. People say R4 is good but.... Hmm. All the silly shapes will be noisy. I've bought a scorpion exo1400 which seems a great balance of spec, price and quality.
I have a Shoei rf1200 and a Ruroc 4.0. I like the style of Ruroc but you are gambling on the production quality and customer service. Shoei and Arai are rock solid if you want something that you know will be what you pay for.
Hey man - how about this.. As you mentioned that you are buying with your own money and want to give your channel an honest unbiased opinion, if you decide to buy the Ruroc and you aren’t completely happy with it we’ll take it back no questions asked? Archie
@Bikes I Like I know you got sights on the Rapide. It's not quite as padded but does look the part. Is more bulkier than the Glampster in the retro line as Arai pad their shells up. Quantic is not as much as a sport style helmet as most and has a more 80s look IMO. Worth a look
The Arai is firming as my favourite. I have seen some coloured options I like but they're the new 2023 colours and not yet available here. But by the time I'm ready to buy they might be good to go!
What about helmets with internal visors or even flip up lids? My go to helmet now is a HJC rev 19. Certified both open and closed. You may like the HJC V90 and V10 models. Do t worry if u can’t get them in aus, if it’s EC certified it’s legal here. Just bring them in from either fcmoto or motardinn.
I have all 3 makes. Putting Ruroc anywhere near in the same conversation as shoei and Arai is a joke.

Arai definitely makes the most comfortable helmets I’ve ever felt.
White reflects heat and is cooler than black. Another advantage is that it makes you more visible and is therefore safer than a dark colored helmet.
If possible, I would browse at one of the stores and try a few on to see which fits the head best and feels most comfortable. The Shoei GT air 2 was probable the best fit for my head shape out of the helmets I tried on, Shoei, HJC & AGV.

Champion helmets? Not familiar with that brand either. Thanks for the recommendation Richard, I'll check them out!
Ruroc looks like it belongs on a Stormtrooper I’d pick the Arai or Shoei. Since you don’t like the Shoei guess it’s the Arai.
Ever notice how high-quality audio products don't need marketing? Sennheiser HD800 series are all hand-made in Germany, as Aria and Shoei are also hand-made in Japan.
Or go watch Isle of Mann TT and see what helmets they are using. I dont think you will find rurock used. In fact, there is not enough money in the world for me to use rurock as a daily driver.

Ah yes the flip lid! I'll check it out Andrew.
Until you put one on, only then will you be able to make the right decision
That's true, which instantly rules out the Ruroc.

Always get the helmet that fits best! A poor fitting helmet won't give the same protection. Nice one.
