Manufactured in Italy, Vertex, the premier brand of OEM replacement pistons, is the OEM supplier to KTM and numerous European motorcycle and go-kart manufacturers.

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' four-stroke pistons are forged from the highest quality 2618 aluminum alloy for superior strength and durability. Vertex uses unique piston profiles and compression ratios to maximize power and performance while reducing blow-by and oil consumption.

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
