ILM WS901 Dirt Bike Helmet Kit — Matte Black L with DOT Certification, Goggles & Gloves

The ILM WS901 is a DOT-certified off-road helmet kit that pairs a lightweight motocross shell with goggles, gloves and a balaclava for full-face protection during dirt biking and ATV rides.

Designed for riders who need reliable head protection plus practical accessories in one purchase, the ILM WS901 kit combines an FMVSS 218/DOT-compliant helmet shell with a detachable, washable liner, an adjustable sun visor, tinted goggles, breathable gloves and a face mask. Available in multiple adult sizes, the package aims to simplify gear selection by delivering coordinated components built for comfort, airflow and everyday off-road use.

How does the ILM WS901 protect my head and face while riding?

The WS901 helmet meets DOT and FMVSS 218 standards for impact protection and retention. Its full-face motocross profile shields the chin and jaw while the included goggles and balaclava guard eyes and lower face from dust, debris and wind.

• DOT/FMVSS 218 certified shell for validated impact performance
• Full-face design covering chin, jaw and temple areas
• Tinted goggles reduce glare and seal against dust
• Balaclava adds wind protection and moisture control

Will the ILM helmet stay comfortable on long or hot rides?

Comfort is addressed through a three-dimensional cut inner liner that conforms to your head and is fully removable for washing. Multiple vents create a continuous airflow path to move heat out and draw fresh air in, helping keep riders cooler during extended or high-exertion sessions.

• Detachable, washable breathable liner for hygiene and fit
• Strategic venting for intake and exhaust airflow
• Ergonomic interior shape to reduce pressure points
• Lightweight materials to lessen neck fatigue

How do the goggles, gloves and visor improve visibility and control?

The kit’s tinted goggles protect eyes from glare and flying debris while fitting comfortably under the helmet’s opening. An adjustable sun visor lets you tune the shade angle quickly to block direct sunlight, and the included gloves provide grip and dexterity for throttle, brake and clutch control.

• Tinted goggles cut glare and shield against dust and bugs
• Top- mounted knob adjusts visor angle without tools
• Gloves designed for grip, flexibility and ride feel
• Mask reduces wind chill and stabilizes goggles under high-speed airflow

What size should I choose and how accurate are the fit options?

ILM offers the WS901 in five adult sizes with head circumference ranges to help you pick the best fit. Measure around the largest part of your head and compare to the provided millimeter ranges to select a size that places the helmet snugly without excessive movement.

• 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")
• Adult-2XL: 630–640 mm (24-3/4"–25-1/4")

Who is this for: The ILM WS901 kit is aimed at recreational and utility riders who want a ready-to-go off-road package—motocross, trail, ATV and general dirt riding—without buying accessories separately. It suits riders who prioritize certified protection, washability, ventilation and the convenience of a coordinated helmet, goggles, gloves and face mask in one purchase.
