Shoei X-12 Motegi Marquez Helmet

The 2013 MotoGP Season saw Marc Marquez take his first ever MotoGP Championship in his rookie year - the youngest rider ever to do so. Marquez took the MotoGP paddock by storm, winning six races, finishing on the podium in 18 different rounds, qualifying on pole at nine of those rounds and setting eleven fastest laps of the race. In the 17th round of the 2013 MotoGP Championship in Motegi he brought with him a special graphic helmet with a special Japanese flag design in honor of Honda's home race and for good luck as he looked to clinch the championship title.

Born from racing, the Shoei X-Twelve 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 Marquez Motegi Helmet (Size XL Only) 4.7 5 98 98
Loud but good racing helmet Maybe I've been spoiled by Arai. I've owned a mid-tier Shoei before and thought it was a pretty good and comfortable helmet. I bought this helmet because it was incredibly comfortable. Unfortunately it is very loud. Shoei admits that. Other than that, the helmet is great, pretty standard functionality, quality construction. You can pop-out the padding, it has good aerodynamic qualities, it's fairly light (noticeably lighter than my Arai), great visibility, and has good build quality. I'm just not excited by it because it's a Marquez theme and since the latest MogoGP championship, I can't stand the guy. November 20, 2015
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
Excellent helmet Love the Shoei X-twelve! The helmet is stylish, light, had a great vision field and has emergency pull tabs, which is the best feature out there in my opinion. October 26, 2015
Shoie x12 Awesome helmet. Will recommend if your looking for a good helmet at a good price. August 4, 2015
Excellent helmet, Great protection. Raced with Shoei X-12 for 2 years till major crash. Sent into Shoei for evaluation and the said it was toast. The protection of the helmet is out-standing. Fit was overall a little tight (medium), but broke in over time. The ventilation was a little on the short side and the helmet is subject to fogging, beware if you race in the rain. Visibility is adequate, but not up to AGV Corsa which has a little more visibility when in the head down position. Buffeting at high speed is adequate, but tends to lift slightly. The protection of the Shoei X-12 is outstanding and their customer service is excellent. Yes it is an excellent helmet and would recommend it. July 27, 2015
Luxury meets safety It is like being in one world while your body and motorcycle operate in another. The cheek pads break in at 1000 miles, it is a racing helmet, so it is stiff there. I like everything about this helmet. I would be typing all day to explain how awesome. I feel much safer than with my old Fox V3 (Moto) or HJC. This helmet brings out the hooligan. I normally wear an extra large and this fit perfect in XL. I bought the blue mirrored shield to go with it, no chips yet! May 23, 2015
Best helmet Have had this helmet for about a year and best investment I made style is awesome and looks great always getting compliments June 1, 2015
Not worth the money Heavy, loud, fogs up, cheek pads and liner wear out very quickly. I've had much cheaper helmets that have been much better quality. Don't waste your money. April 19, 2015

tine l: my son loves this helmet. Fits perfect and does his job. Sep 30, 2015
Ronald P: Because the X12 is the best helmet on the market and Marquez is the best rider on the planet! Aug 11, 2014
A shopper asked: Hi,

Planning to order the X12 but unfortunately dont have the option of trying it before purchasing online. Measured my head above the eyebrows and it turned out to be between 59.5-60.5 cm. As per the sizing chart I should be ordering the size L.

Can anyone suggest if this is a good idea or will the L be too small?

I normally wear the L in AGV K3 and it fits snug. XL in AGV and GMax becomes a comfortable but not really a race fit.

Daniel L: My head measured in at 59.5cm and I tried on the Shoei X-12 Marquez Helmet in Large. This fit my head perfectly. Really wonderful. By comparison I own the Arai Corsair V Black Frost Helmet in XL. This fits snugly, but not as snug/comfortably as the X-12!

I'm definitely getting this one once it's in stock.

Hope this helps.
