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 Honda CB750 is an air-cooled, transverse, in-line-four-cylinder-engine motorcycle made by Honda over several generations for year models 1969–2008 with an upright, or standard, riding posture.

The Honda CR series was a line of two-stroke off-road motorcycles made by Honda from 1973 to 2007. They are racing motorcycles with countless trophies in the 125, 250 and 500 motocross classes.

The Honda RVF750R RC45 was a fully faired racing motorcycle created for homologation purposes for the Superbike World Championship by Honda Racing Corporation. The RVF750R was the successor to the VFR750R RC30. Like its predecessor, the RVF750R featured a DOHC liquid-cooled V4 4-stroke engine with gear driven cams and a single-sided swingarm, but unlike the RC30 it utilized electronic fuel injection, in a setup very similar to the production 1992 NR750. The US spec engine had a 749.2cc capacity and was rated at 101 horsepower; the European version was rated at 118 horsepower. A simple rewire modification to the PGM-FI box increased power in the US engine up to the 118 hp. It was manufactured from 1994 until 1995 and sold in limited numbers, followed by the VTR1000R SP-1 RC51 in 2000. Unlike the VFR750R RC30 and VFR750F from which the engine was originally derived the gear drive for the cams was moved from the centre of the engine in between the cylinders to the one side allowing a slightly narrower engine.
The Honda NSR500 is a road racing motorcycle created by HRC and debuted in 1984 for the Grand Prix motorcycle racing's 500 cc class. Honda won ten 500cc World Championships with the NSR500 from 1984 to 2002, with six in a row from 1994 to 1999. With more than 100 wins to its credit, the NSR500 is the most dominant force in modern Grand Prix motorcycle racing. The 1989 NSR500 that won Honda's third 500 World Championship with Eddie Lawson exemplifies the overwhelming power, acceleration and raw speed that has always been synonymous with Honda's 500 cc two-stroke V4.

The Dunstall Norton was a Norton motorcycle made by Paul Dunstall, a specialist tuner of the 1960s and early 1970s twins originally using some parts from Norton's Domiracer project when the Birmingham factory was closed in 1963. In 1966 Dunstall Motorcycles became a motorcycle manufacturer in its own right so that Dunstalls could compete in production races, and set a number of world records before sales of the Dunstall Nortons declined in the 1970s consistent with the demise of the British motor cycle industry and a corresponding rise in Japanese imports.

The Honda VF750F is a street bike designed by Honda from 1983 to 1985. It has an 86 hp (64 kW), liquid-cooled, V4 engine which sports dual overhead cams (DOHC). The V4's were started a year before with the 1982 Honda Magna VF750C and Sabre VF750S but were adapted for the VF750F in 1983 by reducing the six speed transmission to a five speed because of the change from shaft drive to chain. This reduced the available space in the transmission thus changing to a five speed.
Bridgestone motorcycles were a division of the Bridgestone Tire Co. of Kyōbashi, Tokyo, Japan that produced mopeds and motorcycles from 1952 to 1970. Initially producing power assisted bicycles, the division moved on to producing mopeds and then motorcycles. The motorcycles were technologically advanced and powered by two-stroke engines. The high technical specification resulted in the machines being more expensive compared to other manufacturers models. Production was stopped in 1970 to protect the supply of tyres to other manufacturers.
The Transatlantic Trophy was an annual series of motorcycle races between the United Kingdom and America held from 1971 to 1988 and again in 1991.

The Suzuki T500, variously known as the Suzuki T500/Five, Suzuki Charger, Suzuki Cobra and the Suzuki Titan during its model life, is a 492 cc (30.0 cu in), two-stroke, twin-cylinder motorcycle produced by the Japanese Suzuki company between 1968 and 1975. The model was developed as a larger version of the Suzuki T20 which was intended to compete with the large-capacity British twins in the American market. When introduced it was Suzuki's largest displacement machine. Overengineering of the engine led to the bike gaining a reputation for reliability, and being virtually bulletproof. A total of over 100,000 units were sold during the model's production.
