2023 YZ125

On Aug 27, 2022 Last updated Aug 27, 2022

Although nothing has really changed on the 2023 YZ125, we didn’t really expect anything different after last year’s all-new look. But, most two-stroke fans know that Yamaha deserves credit whenever they release next year’s two-stroke model, because that is something that Kawasaki, Honda and Suzuki haven’t done 15 years. It is left to Yamaha to defend Japanese two-stroke honor against the Austrians and Italians. So sit back an enjoy watching the newest Yamaha YZ125 up close and personal.
