This spare part is intended for the refurbishment of the cylinder head during a cylinder-piston disassembly. This VERTEX cylinder head gasket is designed to replace the gasket provided in VERTEX cylinder-piston kits and helps restore the seal between the cylinder head and the cylinder during a rebuild. Ideal for maintenance, servicing, or preparing a motocross engine where every gasket matters.
Before installation, check the condition of the mating surfaces (cylinder head and cylinder), clean them, and adhere to the torque specifications recommended by the manufacturer. Compatible with many motocross models; examples among the most common include: YAMAHA YZ 250 (2026), FANTIC XX 250 (2026), and YAMAHA YZ 250 (CG23, 2023).
For any cylinder head intervention, prefer suitable parts and follow workshop procedures to ensure a clean and safe operation of your machine.
