Superbike World Championship
Superbike World Championship (also known as WorldSBK, SBK, World Superbike, WSB, or WSBK) is a silhouette-class road racing series based on heavily modified production motorcycles, also known as superbike racing. The championship was founded in . The Superbike World Championship consists of a series of rounds held on permanent racing facilities. Each round has two full length races and, from 2019, an additional ten-lap sprint race known as the Superpole race. The results of all three races are combined to determine two annual World Championships, one for riders and one for manufacturers. The motorcycles that race in the championship are tuned versions of motorcycles available for sale to the public, by contrast with MotoGP where purpose built machines are used. MotoGP is the motorcycle world's equivalent of Formula One, whereas Superbike racing is similar to sports car racing. Europe is Superbike World Championship's traditional centre and leading market.

Circuito De Jerez
Circuito de Jerez – Ángel Nieto (formerly known as Circuit of Jerez and Circuito Permanente de Jerez), is a racing circuit located close to the city of Jerez de la Frontera, south of Seville and deep within the sherry-producing region in the south of Spain. The project was led by the Spanish engineer Manuel Medina Lara, based on a preliminary idea from Alessandro Rocci. Circuit history The circuit opened on 8 December 1985. During 1986 the circuit hosted the first international motorcycle event in Spain in March and the Formula One Spanish Grand Prix in April. The circuit's relatively remote location hindered significant spectator turnout, although up to 125,000 can be accommodated. Because of this, F1 moved to Barcelona following the 1991 race. In 1992, the track eliminated four corners to create the long right hander ''Curva Sito Pons''. Due to the hosting of the European Grand Prix in 1994, a new chicane was created (the ''Senna'' curve) at the corner where Martin Don ...

Highsider
A highsider or highside is a type of motorcycle accident characterized by sudden and violent rotation of the bike around its long axis. This generally happens when the rear wheel loses traction, skids, and then suddenly regains traction, creating a large torque which flips the rider head first off the side of the motorcycle or over the handlebars. The initial traction loss may be caused by: * New tires with wax or similar compounds on the sides of the wheel, or smooth tire on the edges giving low grip on first usage until the asphalt sands the rubber a little bit * Locking the rear wheel through excessive braking * Incorrect downshifting technique, producing excessive engine braking (even if the motorcycle has a slipper clutch) * Applying too much throttle when exiting a corner * Oversteering the bike into the turn by shifting weight to the front wheel and using balance to drift the rear wheel sideways * Exceeding the lateral grip through too much speed (although, this is more lik ...

Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake ai ...

Inline-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...
