ILM Carbon Fibre Off-Road Dirt Bike Helmet (M) — DOT-Certified Motocross Helmet, 4-in-1 Set with Goggles Gloves Mask

The ILM WS901 is a DOT-certified off-road helmet that ships as a complete 4-in-1 set—helmet, tinted goggles, gloves, and a balaclava—designed for motocross, ATV, and trail riders.

Built to meet DOT (FMVSS 218) safety requirements, the WS901 blends a lightweight carbon-fibre look with rider-focused features: an adjustable sun visor, a removable washable liner, and a multi-vent system. The package includes accessories intended to reduce dust, wind, and glare so you can spend more time riding and less time swapping gear.

How well does the ILM WS901 protect riders?

The WS901 is engineered to satisfy DOT/FMVS S 218 standards for motorcycle helmets, offering head protection for on- and off-road use. Its shell design and EPS impact liner work together to manage impact forces while the included chin retention system keeps the helmet secure during active riding.

• Meets DOT/FMVS S 218 certification for road-legal protection
• EPS impact-absorbing liner integrated inside the hard shell
• Secure retention strap for a snug, stable fit during motion

Which sizes are available and how should I choose?

The helmet comes in a range of adult sizes from S through 2XL to fit different head circumferences precisely. For the best fit, measure the circumference at the widest part of your head and match it to the manufacturer’s size chart to avoid pressure points or 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")

What comfort and ventilation features keep you cool on long rides?

Comfort is prioritized with a three-dimensional, breathable inner liner that conforms to head contours and is fully removable for washing. A network of intake and exhaust vents channels airflow through the helmet to remove heat and moisture so you stay comfortable during warm or strenuous rides.

• Detachable, washable 3D-cut liner for hygiene and fit tuning
• Strategically placed vents for continuous air circulation
• Padded interior surfaces designed to reduce hotspots on longer outings

How do the included goggles, gloves and visor improve rideability?

The WS901 package is intended to be ride-ready: tinted goggles reduce glare and shield your eyes from dust, gloves enhance grip and control, and an adjustable sun visor lets you fine-tune shading without tools. Those accessories are particularly useful when conditions change rapidly on trails or tracks.

• Tinted goggles: glare reduction and dust protection
• Gloves: improved grip and hand protection for better control
• Balaclava mask: wind and dust barrier, comfortable under-helmet layer
• Top-mounted visor knob: quick angle adjustments to block sun

Who is this for? The ILM WS901 is aimed at recreational and amateur riders who need a DOT-compliant helmet with practical accessories out of the box. It suits motocross and ATV enthusiasts who want a single purchase that combines visibility control, dust mitigation, and washable comfort features—available in a wide size range to fit most adult riders.
