Description

The Wossner piston kit 8011D050 features a 54.69mm (+0.50 oversize) bore, tailored for KTM 125cc two-stroke engines produced between 1987 and 1993. This high-performance forged piston is designed to enhance heat dissipation and structural reliability. Its elliptical profile helps ensure even distribution of pressure and thrust loads, reducing the risk of piston distortion under high thermal expansion. The component is precision-engineered in Germany, reflecting consistent build quality and performance reliability.

Features

High-strength forged piston construction for enhanced durability
Engineered for efficient combustion heat transfer to the cylinder wall
Elliptical design distributes bearing surface and thrust loads evenly
Made in Germany to high engineering standards
