A sportbike, or sports bike, 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 other motorcycles. Soichiro Honda wrote in the owner's manual of the 1959 Honda CB92 Benly Super Sport that, "Primarily, essentials of the motorcycle consists in the speed and the thrill," while "Cycle World's" Kevin Cameron says that, "A sportbike is a motorcycle whose enjoyment consists mainly from its ability to perform on all types of paved highway – its cornering ability, its handling, its thrilling acceleration and braking power, even (dare I say it?)
 its speed."
Silver Streak is a fictional superhero character created by Joe Simon that first appeared in "Silver Streak Comics" #3 (cover-dated March 1940), from Lev Gleason Publications.
 He is believed to be the second-ever comic book superhero whose primary power is speed; All-American Publications' The Flash preceded him by two months.
 However, Silver Streak beat out National Allied Publications' Johnny Quick (who debuted in 1941) as the first superhero whose two powers were speed and flight.
 Silver Streak has a kid sidekick called "Mercury" (soon changed to "Meteor"); he is also assisted by a hawk named "Whiz".
A speedster is a superhero whose powers primarily relate to super-speed.
 Primary abilities shared by all speedsters include running at speeds far in excess of human capability (to varying degrees) and resistance to the side effects (air resistance, inability to breathe, dynamic shock resulting from contact with objects at high speed, etc.) that result from such velocity.
 In almost all cases, speedsters are able to physically attack opponents by striking them while at high speed to impart huge amounts of kinetic energy without suffering harm, although this has on rare occasion been lampshaded by characters discovering that they cannot do this and suffering severe injury from the attempt.
 A variety of other powers have been attributed to speedsters depending on the story, the origin of the power, and the established continuity and rules of a given universe.
