Wiseco Piston Kit 56mm Bore Gas Gas EC 125 2002-2007 Honda CR125R 1995-2003 Yamaha YZ125 1997-2004 762M05600

When you're pushing a 125cc 2-stroke to its limits, your piston is doing the heavy lifting—and OEM units simply can't handle sustained high-RPM demands. The Wiseco 762M05600 GP Series delivers the strength and precision you need to build reliable power without constant rebuilds. This is the kit serious riders choose when durability and performance matter equally.

Built from aerospace-grade forged aluminum with an Electra-coated crown, this piston resists thermal stress and wear that typically ends stock pistons prematurely. The ArmorGlide coating further reduces friction losses, meaning cleaner combustion and more usable horsepower. Whether you're racing Gas Gas, Honda CR125R, or Yamaha YZ125, you get the exact bore diameter and fitment needed for a straightforward bolt-on upgrade.
