WÖSSNER Pro Series Forged Piston (manufacturer ref. 8713DA) — Designed and machined in Germany for off-road use, this forged piston is aimed at riders looking for a robust and precise engine part for their YZ 250 F. Its forged aluminium design provides density and material homogeneity conducive to stable engine behaviour, while the skirt benefits from an anti-friction treatment to limit wear and tear during revving.
This piston is suitable for cross and motocross use, compatible notably with YAMAHA YZ 250 F (CG27/CG33) 2009–2011 models. The finish and machining meet Wössner standards for a precise fit in the cylinder, making installation easier during engine preparation or top-end refurbishment.
Motoblouz reference: please ensure to check the oversize (letter A) and bore tolerances before installation to guarantee a proper fit for your engine.
