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.
