Bell MX-9 MIPS Dirt Helmet - Gloss Twitch DBK 24 Black/White (Medium)

The Bell MX-9 MIPS Dirt Helmet is built for off-road realities where roost, rocks, and mud are part of the ride. Its tough polycarbonate/ABS shell pairs with an integrated MIPS energy management system to help manage impact forces while you stay focused on the trail ahead. Whether you’re riding a fast line through dusty turns or navigating rough washouts, this helmet blends protection with comfort, so you can ride longer with confidence.

Smart protection meets all-day comfort

The MIPS energy management system works to reduce rotational motion during angled impacts, while the shell’s rugged construction handles trail debris and speed. The Flying Bridge Visor adjusts for sun, weather, or glare, and the built-in air intake vents work in concert with Velocity Flow ventilation to keep you cool from front to back.

• Lightweight polycarbonate/ABS shell with MIPS energy management for responsive protection
• Fully adjustable Flying Bridge Visor with air intake vents and Velocity Flow ventilation for cooling performance
• Removable interior liner that is washable and anti-microbial for easy upkeep
• Three shell and EPS sizes provide a precise, secure fit across head shapes
• DOT certified and FMVSS 218 compliant, backed by an industry-leading five-year warranty

In real-world riding, a helmet that breathes and fits well makes a big difference. The MX-9’s ventilation channels move air through the helmet to help you stay comfortable during long sessions, while the visor adjusts to shield you from sun or spray. The combination of protective construction and a tailored fit helps you stay focused on the ride instead of fussing with gear.

Care, maintenance, and everyday use

The interior liner is removable for washing, and its anti-microbial properties help keep odors at bay between washes. When you need to hose it off after a muddy ascent or a sandy descent, cleaning is straightforward and quick.

• Removable interior liner for easy cleaning and quick refresh between rides
• Anti-microbial lining helps control odor and bacteria between outings

Sizing is designed to accommodate different head shapes with three shell and EPS options. This flexibility, along with a robust five-year warranty, helps provide long-term value. Availability, color options, and pricing may vary by region, so check with your local Bell dealer for current details.
