VERTEX Cast Piston designed for small single-cylinder motocross bikes: a robust and reliable replacement part to restore the sealing and precision of your 50 cm³ engine. Machined from an aluminum alloy, this EF oversize piston maintains the original profile and is aimed at riders and workshops looking for a solution compatible with Beta/KTM 50 engines.
Suitable for KTM/Beta 50 and similar models (usage references indicated for 50 cm³), this piston is installed as a replacement during an EF oversize re-bore. Before installation, check the piston-ring clearance and the condition of the cylinder to ensure proper break-in and a long lifespan. An essential replacement part to restore displacement and engine performance after wear or re-boring.
