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's four-stroke pistons are forged from the highest quality 2618 aluminum alloy for superior strength and durability.

GP Racer Choice:
This piston stands out for the exclusively machined T-Bridge, inspired by F1. Its racing profile and the special shape of the head allows for the maximum compression ratio with a great performance implementation without any loss of reliability. The piston kit is completed with nitride ring set and a DLC coated pin.

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
  • Forged piston developed with Vertex technology and high compression
  • Due to the higher compression, power and torque can be improved across entire rpm range
  • Compression: 13.7:1
Kit includes:
  • Piston with chosen bore
  • Standard bore: 76.95 mm
  • Piston rings
  • Wrist pin
  • Circlips
