Vehicle assignment
The piston is assigned to the Yamaha WR 250 F (CG 22), built in 2005. The assignment explicitly includes this model and this complete year range.
Selection note
The diameter of 76.97 mm, the bore diameter of 77.01 mm, the marking B and the oversize +0.01 are particularly relevant for the selection of parts. In addition, the compression ratio of 12.5:1, the three piston rings and the forged double bridge characterize the specific design. If these technical features match the intended application, the piston can be clearly classified based on its specification.
