Shoei X-12 Daijiro Helmet 4.8 5 85 85
love this helmet! This helmet is awesome I really fell in love with it. Believe it or not it's a good commuting helmet in my opinion (I ride with it everyday) and an even better track helmet. It's fairly light, comfortable especially for track helmet and quiet when the vents are closed, which brings me to my only little con its a little loud at high speeds when the vents are open, wich for me is almost all the time because I don't like when my visor fogs up I mean who does right. But other than that this helmet is marvelous and would not only recommend it but would buy it again if had the option. December 5, 2014
Its no x11, but its pretty good Good solid fit, and light. Had it for a year now and cant get over the fact that It whistles like a banshee no matter what I do. Required smaller cheek pads out of the box as well. Maybe the x11 spoiled me, no whistling and fit perfect with stock pads. August 31, 2014
Pretty much perfect!!! I bought a shoei x12 because i wanted the best track helmet money could buy and im positive i got it. I take a size L and its a snug, firm fit without being over tight, and the linings are super comfortable. The field of vision is amazing, i can see pretty much everything that i can see without a helmet on. The weight is also really good, not too heavy but not light either which i think is a testament to the quality and durability. I also was told by the lads where i bought it that Shoei wind tunnel test them to 300kmh. The x12 is a little bit louder than my GT-Air as far as wind noise goes, but in my opinion thats a part of the thrill of going fast is hearing that wind screaming by your head. The ventilation is also pretty good, not as good as some but it will still keep your head at a good temp and your visor fog free. I was a little bit spooked by the price tag at first, but after using one i believe they are worth every cent, every time i ride im completely confident my head has the best of the best protection on the market. Overall I honestly can't speak highly enough about the x12. If you have the coin, get one.... August 13, 2014
Nice and cool. I only bought it because I had the money and it was so cool looking. Revzilla didn't have my model so I'm writing this review under the solid model. I've only had Shoe helmets so I don't know any better. I owned the RF-1100 as my first helmet. They didn't have one in stock so I bought the X-12. I thought there was something wrong with it at first because it is so noisy. It sucks because I can hardly hear my iPod over all of the noise. In Albuquerque it's all about air flow. I always recommend shoe. They feel good. They look good. July 22, 2014
I got this helmet at a great price under clearance This is one of the best helmet I've ever owned. I got a MEDIUM size. The helmet is a bit loose on the forehead. It tilts down when I'm in a full tuck position. I think i need to get a Small inferior. Overall, I'm extremely happy with it. July 8, 2014
Excellent, well worth the money Another excellent helmet from Shoei, I upgraded from my RF-1100 after a nasty wreck on the street. I couldn't be happier with this helmet, turns lots of heads on the street while being visible and offering track level protection. It is a touch louder than the RF-1100, but it also flows much more air. The only downside to this helmet is the top vents can be difficult to work with good gloves on, but I usually set them before I leave and am fine. May 6, 2014
Great helmet got the helmet yesterday and hit the roads this morning after mounting a spectra mirrored shield. Love the air flow! Slightly more wind noise than my GT Air June 14, 2014
