Shoei X-Fourteen MM93 Black Concept 2.0 Adult Street Helmets
When it comes to the best of the best, Marc Marquez is right at the top of the conversation with regard to motorcycle racers residing here on planet Earth. Seriously. In how many proverbial arenas can the "best" be narrowed to a handful of like, two, maybe three examples. In the world of MotoGP, it is exactly that way, however, and Marc Marquez is right there. In addition to his signature winning style and mind-boggling saves, his attire is equally as recognizable and for 2018, Shoei has introduced the Marquez Black Concept helmet that showcases it in full force.

(Download the following head measuring tape, print, cut and measure your head.)
Each helmet model has small differences in its shape that ultimately affect the fit. For this reason, it is essential to test a helmet before buying it. Test whether it sits on your head properly by putting on the helmet and moving your head to the left and right, as well as up and down while holding the helmet firmly with both hands. If your head can move too freely within the helmet, we recommend that you try a smaller size. If you feel local pressure points, then choose a helmet that is one size larger, or perhaps try on a different model.
Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, repeat for good measure and use the largest measurement.
