Troy Lee Designs SE4 Polyacrylite Mono Helmet
Engineered for riders who demand premium protection without premium pricing, the SE4 Polyacrylite Mono Helmet redefines value in motocross gear. Priced $200 below the SE4 Composite and $400 under its carbon fiber sibling, this model delivers industry-leading safety features at an accessible rate—ideal for amateur racers, trail riders, or budget-conscious professionals seeking reliable head protection.

Advanced Protection System
The polyacrylate outer shell combines impact absorption with durability, excelling on uneven dirt tracks where energy dissipation matters most. Paired with Troy Lee’s triple-density EPS foam core, this system absorbs shocks across varying speeds while remaining 15% lighter than traditional poly shells. A fully integrated Mips slip-plane layer adds rotational impact defense—a critical feature for riders navigating jumps or tight corners at high speeds.

Climate-Responsive Design
Stay focused during intense rides with 22 strategically placed vents that channel airflow through the helmet’s interior. The moisture-wicking 3D mesh liner actively manages sweat buildup during 2-hour endurance races or scorching summer trail sessions. Emergency-release cheek pads ensure quick removal while maintaining a secure fit during 40+mph downhill sprints.

– Breakaway polycarbonate visor (meets ASTM F1849 standards)
– Stainless steel D-rings rated for 300+ lbs tensile strength
