Racer X caught up with Amsoil Honda’s Carson Mumford out at his private test track in Adelanto, California, getting some Supercross practice in before the 2017 Monster Energy Cup in Las Vegas.

Unfortunately, he sustained a broken collarbone in a practice crash last weekend and will be sitting the race out. Mumford will be jumping up to the 250F after he returns to riding. Speedy return Carson.
