Description

This Wossner piston kit is built for Honda CR250R and ATAC250 models from 1984 to 1985, featuring a 66.50 mm bore with an actual piston diameter of 66.44 mm. Forged in Germany, it is designed for strength and efficient thermal performance, promoting effective heat transfer from the combustion chamber to the cylinder walls. The piston’s elliptical profile ensures uniform bearing contact during thermal expansion, helping to distribute thrust loads evenly and reduce the risk of piston failure.

Features

Forged piston for increased structural integrity
Engineered for optimal heat transfer efficiency
Elliptical shape reduces localised pressure under heat expansion
Manufactured in Germany
