Since its introduction in 2003, the X-Eleven has been the motorcycle-racing helmet that all others are judged by. For the 2010 model 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-Twelve 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!

Size Chart for the Shoei X-12 Motegi Marquez Helmet
Wrap a tape measure horizontally around your forehead. Select the helmet that is the closest fit to that size.
A helmet should fit snug on your head. If it moves while wearing, it is too large. If it is painful to wear, it is too small.
