It�s all about the rubber: Heidenau has developed a high-quality compound with a high natural rubber content, resulting in a resilient tyre built to go the distance. Tread design: The K60�s interrupted block chevron pattern delivers solid off-road performance while remaining smooth and stable on the street. Fitment: Available in most common enduro sizes across various manufacturers, either as a K60 or a K60 Scout. Every Scout is a K60, but not every K60 is a Scout. If your rim requires an inner tube, a quality tube can be safely used with any K60 Scout.
