Per the maker's page, the ILM MF509 is a full-face racing helmet with a dual visor system, certified to DOT FMVSS 218 and ECE 22.06. BigBike weighed size L with the visor fitted at 1.567g. Priced at 5.850.000d, it suits riders commuting or touring who often meet sun, rain and need the included Pinlock anti-fog insert.
Real-world check
BigBike weighed a size L with the visor fitted at 1.567g. The shop noted that a rider with a 57 cm head found size L slightly loose with light wobble, though not overly heavy. Choosing a size by its letter alone is therefore not enough.
Per the maker's page, this model comes in two interior structures for two head shapes. Riders who often feel pressure at the temples should tell BigBike in advance so the shop can prepare the alternative for a try-on.
One rider's impression does not represent every head shape, so you should try the exact helmet on before buying.
Labels and standards
BigBike checked the rear label and found DOT together with ECE 22.06. The maker's page lists DOT FMVSS 218 and ECE 22.06 for the MF509, while the box label reads DOT/ECE CERTIFIED. The sources agree on the two systems.
On unboxing, the shop noted 4 intake vents, 3 exhaust vents, a fabric bag, a Pinlock 70, a balaclava, a manual and a sticker. A tinted visor is only included with certain helmet colours. The actual colours match the maker's photos, which helps you compare before deciding.
Certification information does not replace picking the right size, fastening the strap properly and checking the helmet before every ride.
Visor system
The included Pinlock handles the moments when the shield fogs up in rain or cold air. You do not have to crack the visor open and take water in the face. The dual visor system lets you drop the sun visor when leaving a tunnel or riding into the afternoon sun, without stopping to swap the outer shield.
The shop checked the actual stock and found speaker pockets, ready for an SCS intercom. Before a group trip, bring your unit to the shop to check speaker position and fit. The tinted visor comes only with certain colours, so ask before deciding if you want dark eyewear.
Venting and fit
Vents at the chin, front, top and rear feed air through several points. Stuck in midday traffic, you open them all; in cold weather, you close them to cut the direct draft. The visor lock is for open stretches of road, keeping the shield in its closed position against the wind.
If long rides usually leave pressure at your temples, tell BigBike in advance. The shop will prepare the alternative interior for a try-on, check the pressure points and only then settle the size with you.
Model choice
Choose the MF509 if you want a full-face racing helmet with a dual visor, a Pinlock included in the box, and you are ready to check the interior structure before buying. It suits riders who often pass tunnels, meet the afternoon sun or ride in weather that fogs up a visor.
If you prefer a clearly oval interior, look at the AGV K1S; the shop weighed size L with the visor at 1.554g.
Both figures are size L weights on the shop's scale, so they can be compared, but fit for your head shape still needs a try-on.
BigBike weighed the actual stock, size L with visor, and recorded 1.567g.
The maker states a Pinlock 70 anti-fog insert is included in the box.
Per the maker's page, the dual visor system pairs a clear outer shield with a drop-down sun visor.
The maker's page lists a visor lock that keeps the shield in the closed position.

A tinted visor is only included with certain helmet colours, so ask before choosing a colour.
With two interior structures available, you should try the helmet on before settling on a size.
