Shoei X-12 Streamliner Helmet (Black/White/Blue size LG only) Videos

Since its introduction in 2003, the X-Eleven has been the motorcycle-racing helmet that all others are judged by. For this year, Shoei engineers were faced with the grueling task of improving on what is already considered to be the best-performing racing helmet ever conceived. Born from racing, the all-new X-12 Streamliner Helmet combines Shoei’s 50 years of helmet building experience with the very latest technology and most advanced materials to bring you the racing helmet of the future. Throughout its history, Shoei has relied on feedback from professional racers around the globe to continually improve its products, and everything learned along the way has now culminated in the finest motorcycle racing helmet ever developed-the all-new X-Twelve!

Shoei X-12 Streamliner Helmet (Black/White/Blue size LG only) 4.8 5 46 46
x-12 kiyonari dragon helmet I bought my x-12 at a great deal kiyonari red dragon. Looks and feel amazing, took a while to break in but after that the helmet fits like a glove on my head. Coming from Arai corsair v, this helmet for me seems lighter and much quieter and changing shields easy compared to my arai. I would recommend this helmet, best money can buy!!!! November 16, 2012
I would buy it again I am confident that this helmet will protect me. It feels solid, it fits great and looks good. The airflow inside the visor does a great job of keeping the visor clear November 15, 2012
I love this Helmet!! I Owned a Shoei x-11 for quite some time and, after crashing in it on the track, I was concerned about spending so much money on a x-12. However, now that I have the helmet, I have no regrets. I have ridden in other helmets, Arai, Scorpion, Suomy, Icon, but Shoei is by far my choice brand. The fit is excellent, the quality of the air flow and noise reduction is great, and the extra features like the emergency cheek pad release tabs, chin curtain, breath guard, and overall style of the helmet, makes it the best helmet i have ever own.

Fantastic helmet This helmet is very comfortable - the fit is great. Ventilation is pretty good, but it could honestly be better. Noise leve is OK, but I wear earplug anyway. Styling is fantastic - I love how this helmet looks, and it also feels very light (even though it's supposed to be heavier than its predecessor). I crashed in this helmet once in a highside, and had no head injuries, so it did its job very well. August 27, 2012
Shoei, I will never waver again! I will never buy another brand again! I've been riding for 43 years, owned 71 bikes, and many helmets. Way back when, starting with Shoei, I thought Hemet's were much alike..Wrong. After wearing out my Shoei X9, I tried a lesser but very popular brand, Scorpion. I was ok with the Lid but because the X9 was so used up the newness of the scorpion was nice. So when it was time to replace it I read the reviews of all the new helmet's and their tech, Revzilla your the best at vidieoing all you sell. I did own the very first model BellStar around 1970, so I thought I'd give the new Rs1 a try. It is probably a great helmet but not for me. Hot spots on the crown and kind of thin in the liner, not super quality and very loud. So my brother is Aria faithful so I gave the new RX-Q a shot. It was comfy inside, but the shield would not stay up above 20 mph and terribly loud past 30 mph even with all the vents closed. Very frustrated at this point. I tried on the Shoei RF1100 and the Quest, they both felt pretty good but still not perfect. All the reviews said how loud the X12 was, also that it is a race only helmet but I bought one anyway. I don't know why I was suprised. The fit was spot on right out of the box. Comfort and quality is absolutely heaven. Materials and craftsmanship are excellent. venting is very effective, emergency pad removal, and this is by far the quietest helmet I have ever owned bar none. I will only wear ear plugs on the very long rides. I don't know if the late build date has anything to do with it, but this hemet is quiet, and worth every dollar. My main ride is the BMW 1200RT but I also have a BMW HP2 Sport so you know my head is in the direct wind flow. August 16, 2012
Definitely a race helmet Great helmet. I came from using Supmy Spec1R Extreme, and in comparison to that helmet, the shoei gives an overall better quality in comfort and airflow. One thing that I didn't like about the x12 was the fact that it was considerably noisy compared to my old helmet. Can't complain though since its a race helmet with mutltiple air channels July 2, 2012
Great comfort, Great style Purchased the Shoei X-12 Glory 2 Helmet for my husband for his birthday. Its stylish, has great airflow and is lighter and more comfortable on his head and neck than his Shark. June 9, 2012
Top of the line helmet, and looks fantastic! I previously owned a Shoei RF-1000 Troy Lee Designs helmet a few years ago. I bought another bike last year, and have always wanted to get back into a Shoei. I had been wearing an Arai Corsair V, and wanted to try out the Shoei X-12. And of course, it doesn't disappoint. Pros: - GREAT look. Sleek and stylish. You really stand out with this. - Comfortable. Nice fitment. - Vision is excellent. - Lightweight - SUPER easy release of visor! VERY VERY easy (much easier than the Arai) Cons: - Noisy at high speeds. Slight whistle - Vents are GOOD, but not great. - Visor movement is a little rough when opening, not so smooth as the Arai. Overall, a great helmet. It's light, feels great and has superb vision. You definitely get what you pay for! June 4, 2012
