Easing the repair process by saving time and money Vertex Pistons Top-End Piston Kits come with everything needed to replace your piston, top-end gaskets, and wrist pin bearing when the time comes.
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.
- 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
- Replica pistons and all rings are OEM replacements
- Piston with chosen bore, A = OEM
- Piston ring(s)
- Wrist pin with bearing
- Gaskets (head, base, intake and exhaust seals)
