The EXO-R420 helmet continues to set a new standard for Scorpion EXO®'s full face street helmets. An all new shell is more aerodynamic and smaller resulting in an ultra-lightweight Snell-approved helmet. The ventilation system uses a large top vent and mouth vents engineered to allow more airflow to the rider's head while maintaining low noise levels. The EXO-R420 features the Ellip-tec™ II face shield with a latching shield locking mechanism located in the lower center of the shield, making the face shield more secure with a tighter seal against the gasket — and it removes without tools.

How to measure
Measure the circumference of your head with a soft tape, starting just above the eyebrow line (about one inch above the brows) and around the largest portion of the back of the head; repeat to confirm and choose the closest size. Roll-off check: with the chinstrap fastened, try to roll the helmet forward — if the eye port comes down past your brow, size down.

Scorpion officially maintains TWO adult charts. Type B models (EXO-GT930, EXO-T520, Covert FX/II, EXO-R430, EXO-XT9000 Carbon, EXO-AT960) shift ~1 cm smaller per label from L upward — a 60 cm head is L in Type A but XL in Type B. cm ranges are canonical (official sources round inches inconsistently). Youth chart is from an older official PDF — re-verify against a current dealer sheet before featuring prominently.
