The answer is, the newcomer and carbon version of the Schuberth C5. This carbon upgrade is 136 grams lighter than the original C5, and with this weight it manages to be the lightest modular helmet on the market today.

Combining affordability with a lightweight design, the YEMA YM-925 makes it very tough for any other modular helmet to compete. Though it’s made from ABS, which usually adds weight to helmets for extra durability, this one comes at only 3.7 pounds, making it the lightest and most affordable option on the list.

Conforming to current D.O.T. and ECE 22.05 standards, the Lazer Monaco Carbon is an extraordinarily light piece. Weighing in at a airy 1350-1500 grams depending on size, the maker claims it to be the lightest modular on the planet. And it feels as such. Multiple 300-500 mile days have resulted in virtually no neck fatigue amongst its testers here.
