How does the ILM WS901 keep me safer on trails and tracks?

The WS901 meets DOT and FMVSS 218 standards for impact protection and retention performance, giving you regulatory-level safety for street-legal and off-road use. The carbon-fibre-style shell balances strength and reduced weight to lower rider fatigue during long sessions.

What comfort features help during long or hot rides?

• Strategically placed vents for continuous cooling airflow
• Ergonomic interior shaping to minimize pressure points

How do the included accessories improve visibility and protection?

Each WS901 ships with tinted goggles, a balaclava face mask and a pair of riding gloves so you’re ready to ride straight from the box. The adjustable sun visor helps block glare while the goggles protect eyes from debris and bright light.
