Scorpion EXO is known for innovation and quality. It all starts with owning their own helmet factories. Allowing them to control every detail from R&D to production. It also gives them the confidence to stand behind every helmet with a full 5 year warranty. Keeping cost down and value way up, the R420 helmet proves you can have it all on budget.Scorpion EXO continues to set a high standard with the EXO-R420. The advanced polycarbonate shell is lighter and more aerodynamic than earlier models, resulting in a SNELL-approved helmet that is ultra-lightweight. The aero-tuned ventilation system is designed to allow more airflow to the rider's head and maintain low noise levels by using specially engineered, larger vents at the top and mouth. The EXO-R420 also features the new Elliptec II faceshield, which features a latching shield locking mechanism at the lower center of the shield. This provides a tighter seal against the gasket and keeps the faceshield more secure.
