ILM WS901 Dirt Bike Helmet vs HJC CS-MX 2 Helmet

Buy the ILM WS901 if you ride off-road in the US and want a complete kit out of the box: it carries DOT and FMVSS 218 certification, comes with goggles, gloves and a balaclava, and has a knob-adjustable sun visor. The HJC CS-MX 2 is the better-built helmet for pure motocross: an injected polycarbonate shell, ECE 22-05 certification, the ACS channeling vent system and a washable Nylex liner, and owners call it light and sturdy. The ILM wins on included gear and US legality; the HJC wins on shell quality, ventilation design and finish.

  • Choose the ILM WS901 if you need a DOT-approved helmet for trail, ATV or dual-sport riding and want goggles, gloves and a face mask included.
  • Choose the HJC CS-MX 2 if you ride motocross or enduro, already own goggles, and want a lighter, ECE-certified shell with a proven venting system.

What reviewers say

ILM WS901 Dirt Bike Helmet

Owners generally call the WS901 a solid value for casual trail and ATV use, praising the included goggles, gloves and balaclava and the washable liner. Complaints center on sizing running small and on wind noise and visor rattle at speed.

What people mention
  • SizingCriticisedSeveral owners say the fit runs small and recommend measuring the head and sizing up.
  • BundlePraisedBuyers like getting goggles, gloves and a balaclava in the box instead of buying them separately.
  • VentilationPraisedRiders report the vents keep the head cool on hot summer rides.
  • NoiseCriticisedWind noise becomes noticeable at higher speeds, more so than on pricier helmets.

HJC CS-MX 2 Helmet

Owners rate the CS-MX 2 as a solid, light MX helmet for the money. They like the washable liner and ventilation and accept that goggles are a separate purchase.

What people mention
  • WeightPraisedOwners describe it as super light and sturdy for a polycarbonate helmet.
  • VentilationPraisedRiders say the front and rear ACS vents keep air moving on warm rides.
  • LinerPraisedThe removable Nylex interior is easy to wash and stays fresh.
  • VisorCriticisedBuyers note it ships without a visor and needs MX goggles.

Questions and answers

Which is better for ATV and trail riding?
The ILM WS901. It is DOT certified, has an adjustable sun visor for changing light, and ships with goggles, gloves and a balaclava. The HJC is built for motocross tracks.
Which helmet lasts longer?
The HJC CS-MX 2 has the edge on shell quality. Its injected polycarbonate shell and Nylex liner are built to a higher finish, and owners describe it as sturdy. Replace any helmet after a crash.
Is the HJC worth stepping up to from the ILM?
If you ride motocross and already own goggles, yes. You get a lighter polycarbonate shell and the ACS vent system. If you need DOT certification or included gear, stay with the ILM.
Can I use the HJC CS-MX 2 on the street in the US?
It is ECE 22-05 certified, not DOT. Many US states require DOT for street use, so check your state rules before riding on public roads.
Do both helmets fit goggles?
Yes. The ILM ships with tinted goggles and has a goggle-compatible opening. The HJC has a wide eyeport sized for MX goggles, but you buy them separately.
Are the liners washable on both?
Yes. Both have removable, washable liners. The ILM uses a 3D-cut material; the HJC uses Nylex.
