WÖSSNER Forged Piston – Manufacturer Ref. 8003D050
Designed and machined according to Wössner's expertise, this forged aluminum piston is aimed at riders seeking a robust engine part for cylinders with the specified base diameter. Machined for an oversize of +0.50 (letter 050), it features a piston diameter of Ø 56.440 mm, to be paired with a recommended bore of 56.50 mm. Standard compression and a skirt treated with anti-friction to reduce wear at contact compared to a raw skirt.
Original WOSSNER part, manufactured in Germany by specialists in engine components. Compatible notably with older 125 cc trail and enduro models — for example, YAMAHA DT 125 MX (1993), YAMAHA DT 125 LC (1991), and YAMAHA TY 125 (1989) — to be verified according to your engine's cylinder measurement. Ideal for engine refurbishment operations where the +0.50 size is required; ensure that the clearances and assembly are checked by your preparer or mechanic.
