Vertex Piston Kit SX85 03-24/TC85 17-24/MC85 21-24 - Single Ring 0.8 RACE EVOLUTION (46.97)

Because of a cast piston’s ability to contain higher silicon content compared to forged pistons, and because two strokes have lower cylinder pressures when compared to four-strokes, cast pistons are ideal for two-stroke engines.
Vertex pistons are gravity cast from an aluminum alloy with 18% silicon content.

Silicon is important because:

It decreases thermal expansion, which changes the geometry after the piston reaches operating temperature.
With low thermal expansion characteristics, Vertex pistons can be run at tighter tolerances compared with forged pistons.
This creates better power and performance, also making them less susceptible to rattling or breaking.

Silicon gives the pistons better wear characteristics and prolongs piston life by decreasing wear on the piston skirt.
