Features

WISECO Forged Piston - Manufacturer Ref. W4675M07150

Designed for Yamaha 250 quads and top-end rebuild operations, this WISECO forged aluminum piston offers a precise replacement part for oversized bores. Ideal for maintenance or renewal after wear or re-boring, it retains the necessary dimensions to achieve the correct piston/ring clearance.

  • Diameter: Ø 71.500 mm (71.50)
  • Oversize: +0.05 mm (letter 050)
  • Compression: Standard
  • Material: Forged aluminum
  • Reference: W4675M07150
  • Universal: Quad

This piston is suitable for models such as the YAMAHA YFM 250 BEAR TRACKER (2004-2005) and YFB 250 TIMBERWOLF (2001). When re-boring to +0.05 mm, it allows the engine to be rebuilt with calibrated parts: piston, rings, and clips must be installed while respecting the manufacturer's clearances and break-in recommendations.

Choose this WISECO piston for a part produced through a forging process, designed to achieve precise dimensions and geometry suitable for oversized bores. Always check full compatibility with your engine before installation.
