Sports bikes

A sport bike, aka "sportbike" and "sportsbike", is a motorcycle optimized for speed, acceleration, braking, and cornering on paved roads,typically at the expense of comfort and fuel economy by comparison with more standard motorcycles.
 

Some sport bikes are marketed as race replicas, implying that the model sold to the public is identical to the one used in racing, or at least is closer to the racing version than non-replica models. Suffixes R or RR applied to model codes can be interpreted as standing for replica or race replica.
