Troy Lee Designs - SE4 Polyacrylite Yamaha OW-22 MIPS Helmet

SE4 Polyacrylite Yamaha OW-22 MIPS Helmet is a Troy Lee Designs dirt bike helmet built for off-road riders. The SE4 platform remains a favorite for riders who want a planted fit and serious motocross-ready coverage. The Polyacrylite shell helps keep the price more approachable while still delivering the coverage riders expect. The Yamaha OW-22 graphic gives it a distinct finish that stands out in the pits, on the trailhead rack, or in the garage. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.

That dirt-focused shape gives riders a secure feel in fast sections, chopped-up braking bumps, and long afternoons when comfort starts to matter as much as outright protection.

Why We Like It: it feels race-ready without sounding overbuilt, which is exactly what we want from a dirt bike helmet.

Why It’ll Work for You: This is the kind of motocross helmet that fits naturally into a regular rotation because it is easy to wear, easy to clean, and easy to trust.

Variants / Options: multiple sizes and colorways available; check the selector for current stock.
