ILM MO325 open face helmet with dual visor

BigBike weighed size XL with both visors at 1492g. That is heavier than a typical open-face helmet, so if you wear a helmet for hours at a stretch it is worth knowing up front.

On sizing, BigBike tried the helmet on a 59cm head and size L fit without pressing the cheeks, which matches the chart placing 59 to 60cm in L.

BigBike stocks four sizes, M, L, XL and XXL, for heads from 57 to 64cm. The weight above is for size XL and the try-on is for a 59cm head, so for other measurements send your head size on Zalo or come to the shop to try it on.

The MO325 has two visors. The outer one is clear and covers the face, while the sun visor sits inside the shell. A lever drops or retracts the sun visor so you never touch the visor itself, and it holds at each stop.

That means when you ride from sun into a tunnel, or as daylight fades, you switch between tinted and clear on the move rather than stopping to change sunglasses.

The outer visor has Pinlock pins, but no Pinlock insert comes with the helmet. If you often ride in rain or early mist, buy an anti-fog insert to fit on the pins.

The MO325 has a glasses channel at both temples, so the arms slide in without the cheek pads clamping them. If you wear glasses, still bring them to the shop and try the helmet on to be sure.

Speaker pockets are built in on both sides, so the MO325 takes an SCS intercom. Note: an open-face helmet leaves your face exposed, so keep the volume moderate and stay aware of the traffic around you.

ILM divides the liner into four separately adjustable zones so you can add or remove padding to suit your head shape, and the liner comes out for washing. The strap closes with a micrometric buckle, and the vents open and close as you choose.

Choose the MO325 when you ride both in the city and on long tours, like an open face, and want an internal sun visor, speaker pockets and a glasses channel in one helmet.

Look at another model if a light helmet you can wear all day without neck fatigue is your priority, or you need a closed chin bar for long high-speed roads.

The smallest size BigBike stocks is M, for a 57 to 58cm head. If your head is smaller or falls between two sizes, come to the shop and try it on before deciding.
