Grand Prix motorcycle racing is the highest class of motorcycle road racing events held on road circuits sanctioned by the Fédération Internationale de Motocyclisme (FIM). Independent motorcycle racing events have been held since the start of the twentieth century and large national events were often given the title Grand Prix. The foundation of the Fédération Internationale de Motocyclisme as the international governing body for motorcycle sport in 1949 provided the opportunity to coordinate rules and regulations in order that selected events could count towards official World Championships. It is the oldest established motorsport world championship.
Supermoto is a form of motorcycle racing held on race tracks that alternate between three kinds of track surfaces: the hard packed dirt of flat track, the irregular jumps and obstacles of motocross, and the paved tarmac of road racing. Supermoto was originally conceived by Gavin Trippe in 1979 as a segment of the TV show Wide World of Sports. It was something like an all-star game, in which the best riders from the three separate genres of motorcycle racing could temporarily leave their normal race class to come together and compete for the title of best all around racer. Today supermoto is a distinct genre of its own and riders in the other classes do not routinely cross over into supermoto.

The term "Universal Japanese Motorcycle", or UJM, was coined in the mid-1970s by Cycle Magazine to describe a proliferation of similar Japanese standard motorcycles that became commonplace following Honda's 1969 introduction of its successful CB750. The CB750 became a rough template for subsequent designs from all three of the other major Japanese motorcycle manufacturers. In 2011, the New York Times said lightning struck for Honda "with the 1969 CB 750, whose use of an inline 4-cylinder engine came to define the Universal Japanese Motorcycle."

The Kawasaki GPz750 Turbo was a sportbike manufactured from late 1983 to 1985, with two model years – the 1984 E1 and the 1985 E2. Differences were minor, a twin "push/pull" throttle cable for the E2 and different brake caliper stickers. The bike was manufactured in Japan, with parts also shipped to the US and assembled in Kawasaki's Nebraska plant for the US/Canada market to bypass the import tax levied on bikes over 700cc at the time by the US government, a protectionist move designed to save Harley-Davidson which was having financial problems at the time.
A big bang engine has an unconventional firing order designed so that some of the power strokes occur simultaneously or in close succession. This is achieved by changing the ignition timing, changing or re-timing the camshaft, and sometimes in combination with a change in crankpin angle. The goal is to change the power delivery characteristics of the engine. A regular firing multi-cylinder engine fires at approximately even intervals, giving a smooth-running engine. Because a big-bang engine has uneven power delivery, they tend to run rougher and generate more vibration than an even-firing engine.
