My Oakley glasses fit easily inside my other O'Neal helmet. All my Oakley glasses have the straight arms. This Sierra helmet will be my next one. Thanks for the review
Great helmet, nice look, comfort, , nice sun visor. BUT there is always a but . The wind exits on the sides make my life noisy. Annoying. A continuous air flow makes you want to give it away. Oneal should have a system to open and close those exits.
I got my Sierra II last week. Great helmet, and it's true that the only problem is the sun visor is quite difficult to get down. In terms of wind noise it's actually much more quite than my Shark S700, even with the peak on.
Hi, i was wondering how much did you like the oneal sierra over the shark s700, i am about to buy the oneal helmet but unsure if it is the right decision. How good is the sierra in winter/summer? Thanks
Getting back into dirt bike riding and need a helmet for about $100. I liked the O'Neal series 2 Slick matte black but no one has them. Suggestion? 3? Sierra? Will be wearing biking glasses no goggles prob.
Sierra II and Vemar Kona Explorer are the exact same helmets!!! So, is it Vemar who makes the helmets for O´Neal???? I got a Vemar Kona Explorer, and for the price I payed (it´s a little bit cheaper than O´Neal) I must say it´s a great helmet for my use (and price!) It surely is noisy on highway speeds, but it´s a steady noise as long as your head is outside of the buffeting zone of any windscreen... In the buffeting zone, it shakes and vibrates unpleasantly.... The sun visor mechanism gets easier to operate the more you use it, it needs some "running in" time. I use mine without any pin-lock. Fogging haven't been any problem as i just crack the visor a tiny bit open when i see any sign of fogging (i like to get some wind in my face...) Temp range where i´we used it so far have been between 10-32 deg. celsius. I can't say i have felt any affects of the helmet vents, but then again i guess it does the job, since the helmet does not feel overly warm in 32 deg. celsius. Also, it´s a big shell...in sidewinds you can feel the wind twisting and turning. My helmet size is XL. It felt perfectly tight when i first got it, but after some use i think i should have tried size L. Anyways, it´s a great helmet for the price!!!
Great helmet for the money but I have two big issues. It fogs up as soon as I put the visor down, so maybe poor ventilation. Also I find the sun visor distorts my vision so I really don't use it. How do I prevent fogging in this helmet?
Curious if anybody has tried to add Cardo or Sena comms and speakers to this helmet yet.. I'm newish to the KLR650 community and like this helmets looks and am looking at adding a Cardo Slim to it.. thought I remembered reading a comment elsewhere about having to CUT a placement for speakers..
Bruce Meyers you will definitely have to cut the speakers in. I just installed a Sena 30K in mine,but wind noise at highway speeds make it almost unusable. I’m looking for a quieter helmet for comms.
Depends how big your speakers are. I use a freecom 4 unit, and the speakers fit fine in mine. They sit against my ears, but only just so there is no discomfort. Helps with hearing them clearer as well.
Intake vents on the top is a passive, right? Does that mean that I will have a water leaking on my head when I use this on rainy season? Looking to buy this one, thanks in advance.
Are these dual sport helmets w/shield a viable option for a sport ATV rider? I wear glasses, and have a deviated septum making goggles are a bear to wear... The O'Neal appeals to me based on looks and the drop down tinted visor. Can you please compare to LS2 Pioneer?
Yes, it can be a viable option for sport ATV riding. However, a shield is going to fog more easily than goggles, and if the riding conditions are really dusty, you'll want to keep the shield closed. Comparing with the LS2 Pioneer, both have similar shell construction and similar drop down sun visors. The Pioneer has 3 shell sizes compared to the Sierra's 2 shell sizes, so the Pioneer is more compact in sizes XS and Small. The main difference is that the Sierra has a neutral/round oval internal fit, while the Pioneer has a narrow/long oval internal fit around the crown. Therefore, I'd mainly decide based on your head shape. -DrewZilla
RevZilla Right on! Appreciate the feedback. Living in Washington State, rain is prominent and expected which directly correlates to fog... Perhaps I'll stick with what I know and focus more research on eyewear-friendly helmet/goggle combo... Perhaps you could make a suggestion as to where to start?
It's pretty similar feature-wise to the Pioneer, though the Pioneer offers three shells across the size range compared to two shells for the Sierra II. It only makes a difference if you normally wear size small or XS. -DrewZilla
Size indicated by O'Neal is way out , my head size is XXL however oneals XXL is only a large at best compared to similar priced helmets ,, what's going on oneal do you only make kids helmet's ?
I noticed you have 2 vents at the front. One is inside the helmet the other on the exterior. What is the sense of that? To me they are redundant! Any other vent in the helmet that can be regulated?
Im looking for a dirt bike style helmet i like how this has a visor cuz i feel it would be nice to pull up and talk and shit without taking goggles off but i dont like how it is heavy possibility continuing my search
So these dirt helmets with face shields are called dual sport helmets, and we have a large selection. They aren't too heavy either. -DrewZilla *www.revzilla.com/dual-sport-helmets
Yeah, I get mine in and on pretty easily, a lot better than most. Also doest squash the arms against your head which gets very uncomfortable on long rides...
I got this helmet with hope that it would be nicer and better. I have a bell size xs and that was a little tight and according to their size chart I needed a large. So I went form a xs to a large. And this Sierra 11 hurt the hell out of me just putting it on. There was way too much padding and was legit like being reborn it hurt and pulled my hair out everytime I put it on . I also got massive headaches after putting it on and after tkaing it off. It was way tighter than my xs helmet which doesn't even make any sense
Hi, I really love the style of this helmet! Sorry in advance if this is a stupid question but I was wondering if it's possible to wear this helmet with goggles? either way by flipping the visor up all the way or completely removing it? Thanks!
Hey so im new to the moto world. Just got my first oneal helmet O'Neal Unisex-Adult 2SERIES Helmet (SPYDE)…dont really want to wear the googles anymore. Can i put the face shield on my helmet or its specific for that helmet it comes on?
Hi Revzilla, Would you consider this helmet to be a good alternative to my oval Shoei Neotec for my 20% short excursions on fire roads. I do 80% asphalt riding.
We find the Neotec has more of an intermediate oval shape, whereas the Sierra II is a neutral oval between intermediate and round. For me, I can wear a Neotec as well as this Sierra II comfortably, so there's a good chance it should fit you as well. And yes, this is a good affordable option for your 80/20 riding if you don't want to spend all the money on a Shoei Hornet X2. -DrewZilla *www.revzilla.com/dirt-bike/oneal-sierra-ii-helmet *www.revzilla.com/shoei-hornet-x2-helmets
That's not a quick strap mount, just the mounting bolt/rivet for the chin strap. Most have these visible on the exterior, this one is just a bit more ornate than typical. -Zack
On the production version, the ECE sticker is on the back of the helmet next to the DOT label. Even though the version in this video doesn't have the sticker, I just verified our inventory, and the ECE sticker is there. Also, there is the standard ECE tag on the chinstrap. -DrewZilla
Would you advise this helmet to who doesn't do enduro? I have a naked (Duke 390) and I would like a lighter helmet than my AGV K3. Thanks in advance for your answer!
I do not recommend this helmet for street riding. You will get much more wind resistance at speed due to the peak visor. It really is best to stick with a full-face helmet for the street. Also, this helmet is as heavy or even slightly heavier than the AGV K3 SV. -DrewZilla
Yes you can but it wasn't intended to be ridden like that and you would need to replace then bolts for the shield to remain on, even though the shield features would be limited that way. If you have any other questions or concerns, please feel free to reach out to our Gear Geeks at cs@revzilla.com or 877.792.9455. Ride safe, -Pat
My thought for entrepeneurs - devise a 2" wide roll-off system that mounts to the helmet and is motorized and is activated by handlebar mount. This system would solve the terrible vision problem that pro-motocross racers face in extreme muddy conditions. No more pulling in to the mechanics area for new goggles during the race. Roll-offs go across the face shield.

@@RevZilla OMG! Why don't the pros use this in extreme conditions instead of 2 (!) goggles (Ferrandis) and even pulling into the mechanics area for a new set? Is it related to goggle endorsement? It could cost a rider a championship.
@@RevZilla Ok but i think it does come with one in my country because every time i look one up it is already installed on the visor and in the Uk was a preson who reviewed it and said it comes with a pinlock 30
Both would be great options! The O'Neal Sierra II is about a quarter of a pound lighter than the EXO-AT950 and vents more air, which will make it better offroad while the EXO-AT950 has very premium-feeling padding and the convenience of a modular helmet making it more suitable for long touring-style riding. Personally, I would say get the Scorpion unless you live somewhere really hot and sweat a lot, otherwise look at the O'Neal. -DM
@@RevZilla Thanks! I went with the at950 just because I needed it by tonight to take my Riding test. I paid $245 but at least it's modular. And most of my riding will be road 40-75mph... only a few deep offroading outings a year so the weight shouldn't be too bad. Appreciate your feedback
If it fits your head well, then it would be comfortable on a road trip, though for long distances on the highway, you might want to remove the peak visor for better aerodynamics. The peak visor is generally intended to protect you from branches or roost when riding off-road. -DrewZilla
They are two totally different helmets. The Sierra II is a dual sport helmet designed to be used for riding off-road and on-road with or without motocross goggles. The AGV K1 is a helmet for street bikes. If you ride a dual sport motorcycle, the Sierra II is better. If you ride a street bike, the K1 is better. -DrewZilla
Hello. I will buy this helmet. Please help me out guys. Two questions : 1. Can I use any type of bluetooth device? For comunication or music. Wich device fits? 2. It's not such a bad helmet cruising at 120 km/h, is it? And also my head size is 59, should I get the L version?
Yes, you can use most any universal Bluetooth communicator from Cardo, Sena, etc. As for riding at 120 km/h, the peak visor makes it less aerodynamic. You can remove the peak visor for high speed riding if you want. For size, yes, I recommend size large (L). -DrewZilla *www.revzilla.com/dirt-bike/oneal-sierra-ii-helmet
