ILM WS901 Dirt Bike Helmet Kit - Black/White L with Goggles, Gloves & Balaclava, DOT-Certified Ventilated Liner

The ILM WS901 is a DOT-certified adult dirt bike helmet kit that bundles a ventilated, removable-liner helmet with tinted goggles, riding gloves, and a balaclava for complete off-road protection.

This all-in-one motocross set is designed for ATV, MX, and trail riders who want a ready-to-ride solution that balances safety, comfort, and utility. The WS901 meets DOT/FMVS 218 standards and comes in several head sizes so riders can find a close, secure fit. Key design elements include an adjustable sun visor, a quick-release goggle interface, and a washable interior that keeps the helmet fresh after repeated use.

How does the WS901 protect me while riding?

The WS901 shell and certification mean the helmet has passed regulatory impact tests for motorcycle use. It provides coverage across the cranium and jawline typical of off-road helmets, while the included goggles and balaclava protect eyes and face from dust, debris, and wind.

• DOT and FMVSS 218 approved shell for road-legal protection
• Full-face off-road profile shields chin and temples
• Tinted goggles reduce glare and keep out airborne debris
• Balaclava adds wind and dust barrier for face and neck

What ventilation and comfort features help on long rides?

Vent placement channels fresh air in and warm air out to limit heat build-up. The interior liner uses multi-dimensional cut foam and breathable fabric to support the head while managing moisture. When it gets dirty, the liner can be removed and washed to restore comfort.

• Multiple intake and exhaust vents for continuous airflow
• Three-dimensional cut liner for ergonomic fit and breathability
• Fully detachable, washable pads for hygiene and odor control
• Padded chin strap secures helmet without pressure points

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

The tinted goggles clip in securely and reduce glare and dust while maintaining a wide field of view. The visor angle is adjustable via a top knob to block sunlight at different elevations, and the gloves supply grip and hand protection during active riding.

• Adjustable sun visor blocks glare and adapts to sun angle
• Tinted, anti-dust goggles fit with helmet contours for stable vision
• Riding gloves improve throttle and brake control
• Mask reduces inhaled dust and keeps skin shielded from wind

Which sizes are available and how should I choose?

The WS901 is offered in five adult sizes with precise millimeter ranges to help you find the right fit. Measure the circumference around the largest part of your head and match it to the sizing chart. A proper fit is snug without pain; if the helmet shifts, move to the next size up.

• 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 this is for: The ILM WS901 package is aimed at recreational and sport-oriented off-road riders who want a complete, ready-to-use protection kit. It suits ATV and motocross enthusiasts who value a ventilated, washable helmet and the convenience of bundled goggles, gloves, and a balaclava. Choose the correct head measurement for a secure fit, and replace components when damaged or after heavy impacts—this product helps reduce exposure to wind and debris but doesn't eliminate risk.
