Terrible product! I purchased two of these helmets and couldn't be more unhappy with my purchase. The helmet chin curtain flew off on the first ride, the helmet sits very high on your face compared to other helmets and feels unprotected. The wind drag on this helmet is insane and anything above 55mph feels like its trying to pull the helmet off your head. (this happens with vents open or closed) The helmet is terribly noisy, the inner visor does not come down far enough compared to other models and isn't very dark. I find the helmet creates pressure points around the ears partly because it sits so high on your head. I have an old HJC IS-16 that is half the price and twice the helmet... If you are spending this much, go the rest of the way and get a Shoei or the like. If you are a city rider this may be ok for you but for me and my 2014 Hayabusa... this is garbage. May 10, 2015
Great lid overall. The only complaint I have with this helmet, is that the chin cover pops off very easily. The little buttons that hold it on are simply not adequate in my opinion. Most of the time I can't get the helmet off without it coming off. Everything else is awesome. Internals are excellent, and the internal visor is very smooth and not too dark. The pinlock system works flawlessly as I would expect. Graphics and finish are very good as well. The vent position provide a positive feel without being too stiff. Not a complaint but simply an observation: YOU WILL NOT WANT THIS HELMET FOR A COMPLETELY UPRIGHT RIDING POSITION. The top vent when sitting bolt upright is extremely loud when open. The air passes over the vent holes when sitting completely upright, instead of flowing into them. It doesn't whistle but it does make it extremely loud. When the vent is closed there is no issue. Definitely a helmet designed for more of a 3/4 position. May 4, 2015
Great helmet, light and comfortable I bought this helmet to replace a Sparx helmet. This one fits perfect to my head, I'd say I'm intermediate oval, pretty snug at first, but perfect now. It is very well ventilated, when I open the top vents I can feel the air in my head. The pinlock visor works extraordinarily well, you can't make it fog up. The sun visor does fog up at standstill, but if you open the front vent it clears quickly when you start moving. You get a lot of wind noise compared to the Sparx, but I guess that is a trade-off when you get a lot of vents, and it is noisy even with vents closed. Earplugs are a must at highway speeds. Quality is top notch, feels very premium, and it is pretty light. The shell is considerably smaller than the Sparx, so you get less of a wobble head look. March 12, 2015

RevZilla Store asked: Why did you choose this?
Christopher Z: Needed a new helmet and was looking for a quieter (which it is compared to the CL-16 [yr2000]) full face with internal visor (which it has). Although, the chin curtain pops off 50% of the time when removing the helmet and when the top vent is open , it gets super loud. Having it partly open is required in temps over 70F, full open around 90F. Apr 19, 2015
