Elevating the performance of the KLIM F5 helmet—the most intelligently ventilated and impressive lightweight motorsports-engineered helmet in the world—isn’t going to be easy. But thanks to a custom integration with Koroyd energy absorption technology and MIPS’ rotational force mitigation, KLIM has managed to do just that.
This is the next-level F5, and thanks to Koroyd and MIPS, the KLIM F5 now enjoys increased energy absorption efficiency and rotational force mitigation while maintaining the F5’s massively ventilated and lightweight legacy.
For the most active, high-intensity riders on the planet, KLIM’s F5 Koroyd + MIPS is the absolute best. And now, the absolute best is DOT certified.

KLIM + KOROYD
In typical
KLIM fashion, they are taking the technological lead and are the first to incorporate Koroyd technology in a motorsports helmet.
Koroyd is installed in the inner liner, replacing EPS foam at the key impact areas. The unique structure of
Koroyd’s extruded welded tubes creates an unparalleled and consistent engineered core. This core excels at reducing peak G-force transmission while remaining ultra-light and porous.
Koroyd has extremely consistent energy absorption properties—compressing upon impact in a controlled, decelerating process that significantly disperses final impact forces.
