The RZ-63S uses a long-oval shape, narrower side-to-side and longer front-to-back than a round or intermediate-oval helmet, so the same labeled size can feel different than it does in another brand or model. Measure your head against FAST RACER's official sizing chart and check for even crown contact and secure cheek support. If you're between two sizes, size up: a helmet that's too small won't fit correctly no matter how you adjust it, while going up a size still gives you a safe, usable fit
