Cast vs. Forged
What’s better and why:

Four-stroke engines have much higher cylinder pressures when compared to two-strokes and are generally manufactured from forgings. To handle the internal pressures of a four-stroke engine, Vertex’s four-stroke pistons are forged from the highest quality 2618 aluminum alloy for superior strength and durability. Vertex uses unique piston profi les and compression ratios, offered in A, B, C and D sizes, to maximize power and performance while reducing blow-by and oil consumption.

Aiding in the break-in process and reducing wear, every Vertex piston has a Molybdenum Disulphide (MOS2) coating on the piston skirt.
