WÖSSNER Forged piston, manufacturer reference: 8003DA. Forged aluminum piston, made in Germany for 2-stroke and 4-stroke engine parts. Designed for rebuilds or oversize installations, it offers the necessary dimensions for a precise fit in oversized cylinders.
This piston is aimed at riders looking for a machined engine part with controlled tolerances: skirt treated to reduce friction against the sleeve, geometry adapted for oversize bore A. Ideal for work on small displacement engines where assembly precision affects the sealing and longevity of components.
Common applications: Cross and Roadster. Examples of compatible models: YAMAHA DT 125 MX (1993), YAMAHA DT 125 LC (1991), YAMAHA TY 125 (1989). Before installation, check the bore size, piston/sleeve clearances, and consult a professional for installation if necessary.
