ILM Dirt Bike Helmet WS901 (Black White, M) — DOT off-road full-face kit with goggles & gloves

The ILM WS901 is a DOT-certified off-road motorcycle helmet that ships as a ready-to-ride package including tinted goggles, gloves, and a washable balaclava for full-face protection on dirt bikes, ATVs, and motocross tracks.

If you want one-piece, road-legal head protection built for off-road use and delivered with essential accessories, this ILM WS901 kit reduces the time and guesswork of pairing separate gear. The shell meets DOT/FMVS S 218 requirements and comes in multiple sizes to fit a wide range of adult riders. The helmet focuses on airflow, removable comfort liner, and a sun visor that you can tilt to cut glare when light conditions change.

How does the WS901 keep riders comfortable during long trail rides?

The WS901 combines a three-dimensional, breathable inner liner with a channelled vent layout to maintain air circulation and reduce heat buildup. The liner is fully removable so you can wash it after heavy use, helping to control odors and maintain fit.

• Three-dimensional cut liner molds to head shape for ergonomic support
• Multiple intake and exhaust vents direct airflow through the helmet
• Fully detachable, machine-washable inner padding for easy maintenance

What safety and size options are provided for different riders?

The WS901 is built to comply with DOT and FMVSS 218 safety standards and is available in five adult shell sizes to match common head circumferences. Accurate sizing helps ensure the helmet sits correctly for maximum protective benefit.

• Adult-S: 550–560 mm (21-5/8"–22")
• Adult-M: 570–580 mm (22-1/2"–22-7/8")
• Adult-L: 590–600 mm (23-1/4"–23-5/8")
• Adult-XL: 610–620 mm (24"–24-3/8") and 2XL: 630–640 mm (24-3/4"–25-1/4")

What accessories come with the helmet and how do they add value?

Instead of buying gear separately, the WS901 ships as a 4-in-1 kit: gloves for grip and abrasion resistance, a tinted goggle set to manage glare and dirt, and a balaclava-style face mask for wind and dust protection. These pieces are selected to provide a complete off-road setup right out of the box.

• Tinted goggles reduce glare and shield eyes from debris
• Motorcycle gloves improve grip and hand protection on controls
• Balaclava face mask blocks dust and helps with temperature control

How does the adjustable sun visor improve visibility on mixed-light trails?

The top-mounted visoring system includes an easy-to-use adjustment knob so you can change the peak angle while stopped. That flexibility helps reduce direct sunlight and airborne glare without removing your helmet or goggles.

• Tool-free visor angle adjustment via a top knob for quick adaptation
• Peak design blocks sun and redirects mud and roost away from goggles
• Works with goggles installed to maintain eye protection while improving sightlines

Who is this for? The ILM WS901 kit suits off-road enthusiasts who want a single, DOT-compliant helmet that arrives ready for immediate trail use. It’s aimed at dirt-bike and ATV riders who value ventilation, removable comfort liners, and the convenience of bundled goggles, gloves, and a face mask. Choose the correct shell size for a snug fit, and you'll have a helmet designed to balance airflow, comfort, and practical visor adjustments for varied outdoor riding conditions.
