Yamaha WR 250 F (CG 24) [2006] - forged pistons

VERTEX forged pistons for Yamaha WR 250 F

The VERTEX forged piston is designed for the Yamaha WR 250 F (CG 24) built in 2006. As a component of the upper engine area, the piston takes over the moving seal in the cylinder and is designed for a high-compression design.

Properties of the piston

• Piston type: forged
• Material: aluminum
• Piston compression: highly compressed
• Diameter: Ø 76.94 mm
• Bore diameter: 77.00 mm
• Letter oversize: A
• Oversize: STD
• Version: 4T

The forged aluminum construction and the specified high compression characterize this piston for use in four-stroke engines. The dimensions support targeted selection when checking the cylinder bore and piston tuning.

Vehicle assignment

The forged piston fits the Yamaha WR 250 F (CG 24), built in 2006. This assignment must be compared with the model name and year of manufacture when selecting.

Technical selection aid

The piston diameter of 76.94 mm, the bore diameter of 77.00 mm and the code letter A are particularly relevant for the assignment. The STD specification describes the designated oversize version. This allows the technical piston dimensions to be systematically compared with the existing engine before ordering.
