ONeal Sierra RS Adventure Helmet in Echo Black Neon Yellow - ONeal Motocross Enduro Helmets

Think ahead. Protect your greatest asset – While none of us go riding thinking we are going to crash hard and smack the ole noggin, we all know it happens. Having the right helmet is critical. All ONeal helmets are designed using the technologies allowing your head to stay cool with multiple vents and ultra plush liners. The latest in manufacturing techniques helps our helmets to surpass the World’s toughest safety standards.

Designed for riders who demand both performance and protection, the Sierra RS Helmet is built for dynamic riding - whether you're carving through twisty mountain roads or pushing the limits on open highways. Its sporty, snug fit provides a secure, stable feel that minimises helmet movement, giving you greater confidence, balance, and control even at high speeds.

Crafted with aerodynamics in mind, the Sierra RS reduces wind resistance and drag, helping you maintain momentum while staying comfortable and focused. The advanced internal padding system ensures a personalised fit while enhancing shock absorption and noise reduction for a more enjoyable ride.

Visibility is key - and the Sierra RS delivers. Equipped with a clear main visor for sharp, unobstructed views and a secondary integrated sun visor, this helmet adapts to changing light conditions on the go. Ride into the sunrise or through unpredictable weather with confidence, knowing your vision remains crisp and protected.
