VERTEX segment Ø78 mm, designed for original replacement on motocross bikes. This segment sold individually is aimed at riders who maintain their top-end and are looking for a reliable replacement part from VERTEX, a brand recognized in the competition and off-road world.
Intended to restore the seal between the piston and cylinder, this segment helps maintain compression and ensures proper gas evacuation. Ideal during an engine overhaul or for a one-time replacement after wear, it fits into top-end work (piston, sleeve, cylinder) on builds or for regular maintenance.
Manufacturer reference: 590278000005. Before installation, check the axial and radial play as well as the condition of the cylinder to ensure correct fitting and optimal longevity.
