Product Video

LS2 FF327 Challenger CT2 is all about fit, finish, function & performance. It has carbon shell made from exclusive wide-weave carbon fiber for a very light, but strong shell. It has uniquely developed hand layups with advanced, computer-controlled technology to build the ultimate high-performance shell. LS2 uses laser technology to cut all holes in the shell with tight tolerances & high precision.

The eye port gasket on the Challenger uses another LS2 proprietary double injection technology. It also comes with fully adjustable dual intake ports at the top matched via channeled EPS to closeable exhaust ports at the rear. The rider will enjoy true, dynamic airflow when paired with flow separator spoiler & side vents. The adjustable chin vent is dual-ported to keep the shield free from fog, while also keeping the rider cool and comfortable. The Challenger uses an optically correct Class A polycarbonate visor with wide eye port for maximum vision.

The high performance, flat shield securely locks closed and is easily changed using our advanced quick release system. The LS2 FF327 Challenger CT2 utilizes Pinlock Max, ensuring clear vision under the worst of conditions.

How to choose the right size of LS2 FF327 Challenger helmet?
All helmet brands have different sizing as compared to others. Please see the size chart for each product and choose size as per the chart.

How should the helmet fit?
Your helmet should fit snugly and square on your head. Make sure that it is not tilted too far back or forward on your head. Cheek pads touch, but do not press uncomfortably. Make sure there are no gaps around your forehead or back of the neck. With the straps securely fastened, shake your head slightly from side to side and back & forth. If it moves or feels loose, then it is too big. Also remember that the inner liner will compress a little with use, so a new helmet should fit as tight as you can comfortably wear.

How are LS2 helmets as compared to other brands like Axor, SMK?
LS2 has been manufacturing helmets from quite a long time and is also used by riders in Moto3 and Moto2. Ls2 mainly scores higher in its shell design which is light weight & aerodynamic.
