Practical for both the track and training, this kit fits many 350 cc motocross bikes — for example, the Husqvarna FE 350 (2021, 2022) and FE 350 Special Edition (2014). Before installation, please check the precise compatibility with your model and the condition of the drivetrain (sprocket carrier, sprocket, and tensioner).
