The Triumph Speed Triple is a series of motorcycles produced by Triumph Motorcycles. The 1994 Hinckley Triumph was one of the first motorcycles produced in the streetfighter style. The style originated with bikers who, having crashed their race replicas, put the bikes back on the road without fairing, and has since become popularised.

A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a rotor to create friction. There are two basic types of brake pad friction mechanisms: abrasive friction and adherent friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into heat, which must be dispersed.
