  • SmedeteknologiFremstillet af smedet aluminium, har stemplet til formål at begrænse friktionen i cylinderen. Dets legering er designet til at modstå de gentagne cykler fra motocross og off-road.
  • Brug & kompatibilitetDiameter på 76,96 mm med +0,01 overmål for en passende renovering. Kompatibel især med Yamaha YZ 250 F 2018-2019 og WR 250 F 2018.

Egenskaber

Forged piston kit by Prox

PROX's forged piston is designed for 4-stroke off-road engines and engine reconditioning operations. Its forged aluminum construction aims to minimize friction and withstand the demands of motocross. With its standard compression and segments provided in the kit, it supports the replacement of the piston and segments in the top-end.


Design and materials

  • The forged aluminum construction aims to minimize friction to support the piston operation within the cylinder.
  • The specific alloy is designed to withstand the repeated stresses of motocross and off-road use.

Installation and assembly

  • The diameter of 76.96 mm with a plus tolerance is suitable for reconditioning a top-end requiring this size.
  • The segments are provided in a kit to facilitate the piston replacement with the associated components.
  • The standard compression of 13.5/1 makes it easier to replace with equivalent compression characteristics.
  • Manufacturer reference 01.2417.B and product reference CP1612C

Usage and performance

  • The motocross-adapted design tolerates temperature rises and repeated cycles of off-road use.
  • The finish and alloy facilitate the break-in process and contribute to stable piston behavior within the cylinder.
