The X-Fifteen is SHOEI's race flagship — the helmet their MotoGP and World Superbike riders actually wear. The AIM+ shell is shaped in SHOEI's wind tunnel for stability at full tuck, with an eyeport raised so you can see where you're going in a race crouch, not just where you've been.
The CWR-F2R racing shield locks down with a double shield lock and includes a Pinlock anti-fog lens, and E.Q.R.S. cheek pads allow safe helmet removal by first responders.

How to measure
Pass a soft tape measure horizontally around your head about one inch (2.5 cm) above the eyebrows — the largest measurement around the forehead. Move the tape slightly up and down to find the largest reading. If you fall between two sizes, try the smaller size first.

One official SHOEI US chart for all adult models; fit can feel different between models at the same size, and size runs vary per model (3XL only on select models). SHOEI publishes no US youth street chart. 2XL/3XL appear as XXL/XXXL on SHOEI's own chart — normalized here to match our size filter vocabulary.
