The ILM HS711 is a 3/4 helmet with a chin bar that detaches by push-button clips, DOT and ECE 22.06 printed on the label, priced at 3,400,000đ. One mirrored sun visor, no clear visor. BigBike weighed size L with chin bar and visor at 1404g. Suits riders who want one helmet worn two ways, not those who put chin protection first.
Two setups
Stuck in traffic on Hanoi Highway on the way to work, a helmet that switches between open face and closed face suits riders who stop often. The ILM HS711 is a 3/4 helmet with a detachable chin bar, used in two setups. With the chin bar on, the closed shape keeps out dust and insects. With it off, it goes back to a 3/4 with a peak. The helmet's certification covers the 3/4 setup. The removable chin bar does not shield like the chin of a one-piece full-face.
Anyone who puts chin coverage first should choose a one-piece full-face, not the HS711 for its closed look with the chin bar on.
Weight and size
BigBike weighed size L with the chin bar and visor at 1404g. The figure applies only to the setup weighed. When you turn or tilt your head, the actual fit still has to be checked on the rider's own head.
BigBike tried a 59cm head in size L and found it loose, not snug, and the helmet rocked, so at 59cm try both M and L before deciding. Use the printed size chart only as a first filter.
BigBike has only weighed size L with the chin bar and visor fitted. Other sizes and the chin-off setup have not been weighed, so try the helmet on instead of guessing from the current figure.
Chin bar and visor
A rainy Saigon afternoon or a night ride is when a dark sun visor needs planning ahead. The chin bar uses push-button clips on both sides, removed by hand with no tools. BigBike staff tested fitting and removing it. Chin bar off, it is a 3/4 with a peak. Chin bar on, it gives a closed face.
The mirrored sun visor flips up and down by hand and sits under the peak when raised. The helmet has no clear visor and no Pinlock. The dark visor cuts visibility at night or in afternoon rain. The visor carries a glasses-friendly mark, so try it on with the frames you wear. Note: fit or remove the chin bar and move the visor only when the bike is stopped.
Buckle and intercom
Bao Loc pass has early morning fog, so get used to the buckle and intercom before the trip. BigBike staff counted on unboxing: 2 intake vents on the brow, 2 on the crown and 1 large exhaust at the rear. The liner comes out for washing.
The micro buckle works for daily use, but BigBike staff found it a bit hard to fasten with gloves on. Practice the motion while the bike is stopped. This ILM helmet has speaker pockets on both sides and takes an SCS intercom. When following navigation or talking, keep the volume moderate so you still hear what is around you.
Choose or not
Choose the ILM HS711 if you want one helmet worn two ways for commuting and touring. Chin bar off when you want an open face, chin bar on when you want to keep dust and insects out. The sun visor comes built in, and it carries a glasses-friendly mark.
Do not choose the HS711 if you want chin coverage like a one-piece full-face. Also skip it if you often ride at night without planning a clear visor, or if you only want to read the chart and pick a size without trying it on.
BigBike weighed size L with the chin bar and visor, and the try-on was on one rider. If you sit between M and L, come to the shop and try both before deciding.

Measure your head with a tape across the brow and the widest point at the back, snug but not tight. BigBike tried a 59cm head in size L and found it loose, not snug, and the helmet rocked, so at 59cm try both M and L at the shop or send your measurement over Zalo, do not pick from the chart alone. The box holds the helmet, the detachable chin bar, a manual and a fabric bag.
