Superbike World Championship is a silhouette road racing series based on heavily modified production sports motorcycles.

Road racing is a North American term to describe motorsport racing held on a paved road surface. The races can be held either on a closed circuit or on a street circuit utilizing temporarily closed public roads. The objective is to complete a predetermined number of circuit laps in the least amount of time, or to accumulate the most circuit laps within a predetermined time period. Originally, road races were held almost entirely on public roads. However, public safety concerns eventually led to most races being held on purpose-built racing circuits.
