A motorcycle is a two or three-wheeled motor vehicle steered by a handlebar from a saddle-style seat.
A chariot is a type of cart driven by a charioteer, usually using horses to provide rapid motive power. The oldest known chariots have been found in burials of the Sintashta culture in modern-day Chelyabinsk Oblast, Russia, dated to c. 1950–1880 BCE and are depicted on cylinder seals from Central Anatolia in Kültepe dated to c. 1900 BCE. The critical invention that allowed the construction of light, horse-drawn chariots was the spoked wheel.
Chariot racing was one of the most popular ancient Greek, Roman, and Byzantine sports. In Greece, chariot racing played an essential role in aristocratic funeral games from a very early time. With the institution of formal races and permanent racetracks, chariot racing was adopted by many Greek states and their religious festivals. Horses and chariots were very costly. Their ownership was a preserve of the wealthiest aristocrats, whose reputations and status benefitted from offering such extravagant, exciting displays. Their successes could be further broadcast and celebrated through commissioned odes and other poetry.
A sidecar is a one-wheeled device attached to the side of a motorcycle, scooter, or bicycle, making the whole a three-wheeled vehicle. The combination of a motorcycle with a sidecar is sometimes called a rig, outfit, or hack.
An overhead camshaft (OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block.
An iceboat is a recreational or competition sailing craft supported on metal runners for traveling over ice. One of the runners is steerable. Originally, such craft were boats with a support structure, riding on the runners and steered with a rear blade, as with a conventional rudder. As iceboats evolved, the structure became a frame with a seat or cockpit for the iceboat sailor, resting on runners. Steering was shifted to the front.
Robert Hugh Fearon Anderson was a British Grand Prix motorcycle road racer and racing driver. He competed in Grand Prix motorcycle racing from 1958 to 1960 and in Formula One from 1963 to the 1967 seasons. He was also a two-time winner of the North West 200 race in Northern Ireland. Anderson was one of the last independent privateer drivers in Formula One before escalating costs made it impossible to compete without sponsorship.
A sport bike, sports motorcycle, or sports bike is a motorcycle designed and optimized for speed, acceleration, braking, and cornering on asphalt concrete race tracks and roads. They are mainly designed for performance at the expense of comfort, fuel economy, safety, noise reduction and storage in comparison with other motorcycles.
Circus Maximus is a board game that was originally published by Battleline Publications in 1979, but is better known for the 1980 Avalon Hill edition. The game has become very popular at gaming conventions in an oversized form, with 10-foot (3.0 m)-long boards and baseball-sized chariots.
Crystal Palace Park is a large park in south-east London, Grade II* listed on the Register of Historic Parks and Gardens. It was laid out in the 1850s as a pleasure ground, centred around the re-location of The Crystal Palace -- the largest glass building of the time -- from central London to this area on the border of Kent and Surrey; the suburb that grew around the park is known by the same name.
Gaius Appuleius Diocles was a Roman charioteer. His existence and career are attested by two highly detailed contemporary inscriptions, used by modern historians to help reconstruct the likely conduct and techniques of chariot racing. He has been described in some modern sources as the highest-paid athlete of all time.
Crystal Palace circuit is a former motor racing circuit in Crystal Palace Park in the Crystal Palace area of south London, England. The route of the track is still largely extant but the roads are now mainly used for access to the Crystal Palace National Sports Centre located in the park, and to events within the upper parts of Crystal Palace Park. Some parts of the track are closed off but part is used for an annual Sprint Meeting held on the Spring Bank Holiday weekend, until 2017, when it was held on the August holiday weekend.
A motorcycle fork connects a motorcycle's front wheel and axle to its frame, typically via a yoke, also known as a triple clamp, which consists of an upper yoke joined to a lower yoke via a steering stem, a shaft that runs through the steering head, creating the steering axis. Most forks incorporate the front suspension and front brake, and allow the front wheel to rotate about the steering axis so that the bike may be steered. Most handlebars attach to the top clamp in various ways, while clip-on handlebars clamp to the fork tubes, either just above or just below the upper triple clamp.
Crystal Palace F.C. was a short-lived amateur football club formed in 1861, who contributed to the development of association football during its formative years. They were founder members of the Football Association in 1863, and competed in the first ever FA Cup competition in 1871–72.
Zenith Motorcycles was a British motorcycle and automobile manufacturer established in Finsbury Park, London in 1903, by W. G. Bowers. Automobile manufacture only lasted from 1905 to 1906. The first Zenith motorcycle was the 'BiCar' of 1903, based on Tooley's Bi-Car design, which was purchased by Zenith for its own production. The BiCar was a unique design with hub-center steering and a low-slung chassis with the engine centrally fixed.
The featherbed frame was a motorcycle frame invented by the McCandless brothers and offered to the British Norton motorcycle company to improve the performance of their racing motorcycles in 1950. It was considered revolutionary at the time, and the best handling frame that a racer could have. Later adopted for Norton production motorcycles, it was also widely used by builders of custom hybrids such as the Triton, becoming legendary and remaining influential to this day.
The Brighton Speed Trials, in full The Brighton National Speed Trials, is commonly held to be the oldest running motor race. The first race was held 19–22 July 1905 after Sir Harry Preston persuaded Brighton town council to tarmac the surface of the road adjacent to the beach between the Palace Pier and Black Rock to hold motor racing events. This stretch was renamed Madeira Drive in 1909 and the event is still held there, normally on the second Saturday of September each year. In 1936 Motor Sport described the event as: "undoubtedly the most important speed-trials on the British Calendar."
The Berliner Helicopter was a series of experimental helicopters built by Henry Berliner between 1922 and 1925. The helicopters had only limited controllability but were the most significant step forward in helicopter design in the US, until the production of the Vought-Sikorsky VS-300 helicopter in 1940. The 1922 flights of the Berliner and the de Bothezat H1 were the first by manned helicopters.
Motorcyclewheels are made to cope with radial and axial forces. They also provide a way of mounting other critical components such as the brakes, final drive and suspension. Wheels, and anything directly connected to them, are considered to be unsprung mass. Traditionally motorcycles used wire-spoked wheels with inner tubes and pneumatic tyres. Although cast wheels were first used on a motorcycle in 1927, it would not be until the 1970s that mainstream manufacturers would start to introduce cast wheels on their roadgoing motorcycles. Spoked wheels are usually made using steel spokes with steel or aluminium rims. Cast wheels are predominantly made from an aluminium-alloy, but can also be made from more-exotic materials, such as magnesium content alloy or carbon fibre.
The Stanley Cycle Show or Stanley Show was an exhibition of bicycles and tricycles first mounted by the Stanley Cycling Club in 1878 at The Athenaeum in London's Camden Road. Britain's first series production cars were displayed at this show in November 1896. The 34th and last exhibition was held in the Royal Agricultural Hall, Islington in November 1910. It was supplanted by the 1911 Olympia Motor Cycle Show and, a few weeks before that, Olympia's International Motor Exhibition.
