Sizing chart
All Vertex 2-stroke pistons are gravity cast from an aluminum alloy with 18% silicon content. 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.
Details:
- All pistons are heat-treated with a T-5 hardening and tempering cycle
- Piston skirts are coated with a high-tech Molybdenum Disulphite coating for faster break-in time and increased piston life
- Gravity-cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston
- Silicone decreases thermal expansion, therefore can be run at tighter tolerances compared with forged pistons
- The high silicone content prolongs piston life by decreasing wear on the piston skirt, also making them less susceptible to rattling or breaking
- Big Bore pistons increase engine?s displacement, torque, and peak horsepower
- Cast piston in original OEM form for Big Bore cylinder
- Piston with chosen bore, standard bore: 49.45 mm
- Piston rings
- Wrist pin
- Circlips
