Shoei X-12 Montmelo Marquez Helmet 4.7 5 106 106
Shoei X-12 for $399 can't be beat! This helmet has a great fit-and-finish. I have been riding in a Shoei Qwest (Size XS) for about 3 years now. This helmet has been wonderful! Great visibility, air flow, and durability for track and street riding. The X-12 continued to impress me with Shoei products. I have not yet ridden in it so I can't rate Air Flow or Protection (hopefully don't ever have to rate Protection..) but this helmet is wonderful. The 5 shell sizes really caters to a good helmet fit. I was skeptical going up from an XS to S, even staying with the same brand, but the X-12 fits well based on the sizing chart. If you're thinking Arai vs Shoei and have an intermediate oval to long oval head, you should seriously consider Shoei since they are cheaper than the comparable Arai each time. January 20, 2016
Upgrade to the X-11 Bought this to replace my X-11. Both in size XS with the stock cheek pads. X-12 is more comfortable. It is a bit less long front to back compared to the X-11, which makes it a perfect fit to my intermidiate oval head. More room for the ears and not as tight on the cheeks. X-12 is a bit lighter. X-12 is far loader. I have to use ear plugs even for short rides. It is winter, so cannot compare the vent. However, I did notice more fogging at zero speed. Great aerodynamics and wide FOV on both. Bottom line: I love it. January 20, 2016
Great Helmet Great helmet, comfortable, quiet and flows good air (though you do get a whistle from time to time, and with out the chin vent open the visor fogs up pretty quick). Bought it on closeout so the price was great for a top of the line helmet. Only real downside is that with a sena unit there really isnt any great place for the speakers. I set mine extra low in order to still have room for my ears...works, but may buy the earbud adaptor just for the comfort. January 19, 2016
awesome helmet for Superbike. Shoie has really taking there helmets to be one of the best in todays market. Light weight comfort an best SuperBike race helmets today. January 19, 2016
Race specific helmet I purchased this helmet as an upgrade from my Icon Airframe and also for preparation for the track. The good: The helmet fits and is very snug The vision range is very wide The emergency tabs are a great feature to have and hopefully never have to use. Very aerodynamic and the spoiler is a nice touch The locking visor settings are very convenient The bad: It is VERY loud in commute mode, but as soon as you assume an aggressive position, it's like hitting the mute button. The visor also fogs up very easily. If this wasn't priced so low, I would have preferred to stick with my Icon. December 31, 2015
great helmet but currently too foggy I haven't installed the anti-fog piece of plastic yet, but the helmet gets very foggy. In the city, I have to keep the face shield open 1 setting or else I cannot see anything. I have only had the helmet for 2 weeks, so these are first impressions. I will need to see if they sell a replacement face shield that is anti-fog, if installing the fog-guard doesn't help. December 14, 2015
Best helmet I have ever owned Light, stylish and just feels rock solid - it's very comfortable the it fits perfectly. Great for doing shoulder checks at high speed and the field of vision is better than the GT-Air I previously owned. Can get slightly noisy at high speed but nothing to complain about.

9 plus 3 = 12 yr old motogp wrecker PRO: helmet fits snug in the crotch of a Dainese race suit CON: makes you tend to rub up on RM1's when you're not even a contender October 26, 2015
