Hi, Tonly44 a YZ is a motocross bike designed to run flat out that being said if you are strolling down some scenic trail at a slow pace or letting the bike idle for a few minutes your header pipe will turn cherry red, why you ask? It is not a street bike, it is designed for competition and weight is a major factor all necessary components are of the smallest and lightest design necessary to maintain performance under extreme conditions ie. small radiator and inside frame oil reservoir that doesn't get cooled, the majority of your riding needs to be at high speed.
