2020 HUSQVARNA FC 450 ROCKSTAR EDITION

CYLINDER HEAD

The SOHC cylinder head is incredibly compact and light with the camshaft located as close to the center of gravity as possible, significantly improving handling while its shorter valve timing improves bottom end performance and responsiveness. A new optimized rocker arm design features increased stiffness and reduced inertia on both intake and exhaust.
