Because of a cast piston’s ability to contain higher silicon content compared to forged
pistons, and because twostrokes 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.
Vertex Piston delivery with: Kits include piston, rings, wrist pin and circlips.
