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
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
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
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
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
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
