Shoei X-12 Daijiro Helmet (Size LG Only) 4.7 5 117 117
Shoei spotless quality, as usual. I use this helmet as an all-around helmet. Shoei is a good fit for my head shape, so I'm coming from a couple other helmets from the brand (Euro-spec XR-1100 & GT-Air). This one is almost as confortable as the GT-Air, same for the sound level, but a little lighter and missing the sun visor. It is every bit up to Shoei standards of spotless quality and finish. It's European counterpart shows also outstanding crash-test results: http://sharp.direct.gov.uk/testsratings/shoei-x-spirit-ii but I don't know how much the actual US version differs from the Euro-spec one.

Good Track Day Helmet I wouldn't cruise to work on the highway with this guy but if you are on the track and want something that won't rip your head off at 140 mph and provide good airflow at those race tracks in the deserts of california than it's a good bet. May 2, 2016
High quality The moment I opened the box I could tell this thing was well made. When I put it on it was definitely snug on my cheeks, but fit perfectly everywhere else. The vision is wide and the visor is, at least initially, so clear it seems like there's nothing covering your eyes. Considering its size, the helmet is incredibly light, I was shocked. With all vents open you can feel the air coming through the helmet, but at speeds lower than 30mph there's definitely a problem with fogging. I have to pop the visor open every time I stop at a light or enter a low speed zone. In spite of the drawbacks, I love this helmet. April 12, 2016
This product is worth it! ordered my first motorcycle helmet and i loved it. it shipped quick. great helmet, it looks awesome. April 5, 2016
All around excellent helmet in terms of comfort, value, function, design and protection. This is my first helmet. I knew I wanted a quality helmet but nothing too expensive. I don't think I can settle for anything less now. The helmet fits me perfectly (Medium) and feels so comfortable to wear. I have a light silver helmet and I think it looks great and is visible enough. The airflow vents help with warmer weather, but in colder winter, spring or fall weather I have to open the face shield slightly in order not to fog up the inside of the helmet (not a huge deterrent). I recommend the X-12 to anyone who rides! March 29, 2016
Excellent Bang for the buck Get one while there are still a few left..You will be hard pressed to find this level of helmet at a price less than this. Cheek pads will break in after a few rides. March 21, 2016
Great product, excellent features I actually have not ridden with this helmet on yet. But for the price,($400) I already know it is a great helmet. Fit for helmets can be particular, but I already know that size L Shoei Helmets fit me well, and this one is no different. So if you typically wear a size L Shoei helmet, this one will fit the same. Sizing is standard to the RF-1100 which is my current helmet. I purchased this helmet due to the interchangeable visors of the RF-1100, and having 5 or 6 visors for that helmet made the decision easy. Shoei makes a great helmet, and I am sure this one won't dissapoint. March 16, 2016
Close out Price due to introduction of X14 Best helmet I've ever worn. This helmet fits me absolutely perfectly. Manufacture date indicates late 2013 while purchased early 2016. Should be fine for the next 3 years of use. A lot of design, technology and perfect fit for $399! March 15, 2016
