Single Segment VERTEX 46 mm (manufacturer reference: 53010004600N8) — replacement part designed for motocross machines. This unique 46 mm diameter segment restores the seal between the piston and cylinder, an essential condition for clean combustion and consistent engine response. Designed by VERTEX, a specialist in high-performance components for engine endurance, it is aimed at demanding riders who maintain their engine block.
Ideal for motocross riders and workshops looking for a reliable part for engine block restoration. It does not alter the engine geometry: it simply restores the seal and limits compression losses related to the wear of the previous segment. Before installation, check the condition of the piston and cylinder and follow the manufacturer's installation recommendations.
