S3 Large volume valve cover Cylinder head insertRef : SPART00324A / 1149031003

The S3 large volume valve cover is an optimisation part designed for motocross and enduro riders seeking a more controlled engine response and a racing look. Machined from aluminium and presented in anodised blue finish, it adds a distinctly competitive aesthetic while maintaining functional lines suitable for extreme off-road use.

Designed to increase the volume of the valve chamber, this cover aims to promote a more linear power delivery and better traction in low and mid-range revs — qualities appreciated in special stages or technical terrain. Its aluminium construction ensures lightness and good resistance to the stresses encountered in off-road use.
