Harley-Davidson XR-750
The Harley-Davidson XR-750 is a racing motorcycle made by Harley-Davidson since 1970, primarily for dirt track racing, but also for road racing in the XRTT variant. The XR-750 was designed in response to a 1969 change in AMA Grand National Championship rules that leveled the playing field for makes other than Harley-Davidson, allowing Japanese and British motorcycles to outperform the previously dominant Harley-Davidson KR race bike. The XR-750 went on to win the most races in the history of American Motorcyclist Association (AMA) racing. The XR-750 is associated with the careers of racers Mark Brelsford, Cal Rayborn, and Jay Springsteen, and was the favorite motorcycle of stunt performer Evel Knievel. Knievel used the bike from December 1970 until his final jump in January 1977. An XR-750 was included in the 1998 '' The Art of the Motorcycle'' exhibition, and one of Knievel's bikes is in the Smithsonian's National Museum of American History ''America on the Move'' exhibit. * * ...

BSA (motorcycle)
BSA Company Limited is a motorcycle manufacturer which purchased rights to the BSA name from Birmingham Small Arms Company's successor, Dennis Poore's Manganese Bronze Holdings, upon the liquidation of Norton Villiers Triumph in 1978. In October 2016, India's Mahindra Group purchased BSA for £3.4 million in an effort to reintroduce motorcycles bearing the famous BSA name. Origin When NVT Motorcycles Limited was liquidated in 1978, its management, then under William Colquhoun, formed a new company (BSA Company) and bought from NVT the rights to the BSA motorcycle brand. Military motorcycles BSA Company produced military motorcycles (with Rotax engines) and motorcycles for developing countries (with Yamaha engines) under the BSA name. In the latter case, the old "Bushman" name was recalled to duty; it had previously been used on high ground clearance Bantams sold to the likes of Australian sheep farmers. Having moved from Small Heath to Coventry in 1973, Colquhoun moved the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homologation (motorsport)
In motorsports, homologation is the type approval process through which a vehicle, a race track, or a standardised part is required to go for certification to race in a given league or series. The process of testing and certification for conformance to technical standards is usually known as type approval in English-language jurisdictions. The regulations and rules that must be met are generally set by the series's sanctioning body. The word is derived from Greek , . When a car loses the homologation form, that is, it becomes a historic vehicle, it can no longer be part of a competition and can only be used in historic competitions. Requirements In racing series that are "production-based", meaning that the vehicles entered in the series are based on production vehicles for sale to the public, homologation not only requires compliance with a racing series's technical guidelines (for example engine displacement, chassis construction, suspension design and such), but often i ...

Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the power an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. The formula is: : \text = \text \times \frac \times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flathead Engine
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1950s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucas Industries
Lucas Industries plc was a Birmingham-based British manufacturer of motor industry and aerospace industry components. Once prominent, it was listed on the London Stock Exchange and was formerly a constituent of the FTSE 100 Index. In August 1996, Lucas merged with the American Varity Corporation to form LucasVarity. After LucasVarity was sold to TRW the Lucas brand name was licensed for its brand equity to Elta Lighting for aftermarket auto parts in the United Kingdom. The Lucas trademark is currently owned by ZF Friedrichshafen, which retained the Elta arrangement. History Foundation In the 1850s, Joseph Lucas, a jobless father of six, sold paraffin oil from a barrow cart around the streets of Hockley. In 1860, he founded the firm that would become Lucas Industries. His 17-year-old son Harry joined the firm around 1872. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceriani
Ceriani, formerly Arces, was an Italian company that designed and fabricated motorcycle frames and suspensions. The company was founded by Arturo Ceriani in 1951. Arces is an acronym derived from Arturo Ceriani S.r.l. In the European motorcycle industry, it was common for many smaller parts companies to exist, each responsible for creating individual parts to later be assembled into a complete motorcycle. Within a few years of its creation, Ceriani's company was able to successfully make a name for itself by manufacturing components noted for their quality and vision. In 1964, under the leadership of Arturo's son Enrico Ceriani, the companies operations were expanded. Enrico accelerated the expansion by moving the company to a new and more modern plant in Samarate. From 1964 the company was known within the industry as ARCES (an acronym of ARturo CEriani Samarate) but the brand identity was maintained and the company continued to be known as Ceriani by consumers.

Motorcycle Frame
A motorcycle frame is a motorcycle's core structure. It supports the engine, provides a location for the steering and rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the pivoting front fork, while at the rear there is a pivot point for the swingarm suspension motion. Some motorcycles include the engine as a load-bearing stressed member; while some other bikes do not use a single frame, but instead have a front and a rear subframe attached to the engine. Materials In the early days, motorcycles were little more than motorised bicycles, and consequently frames were tubular steel. While the use of steel tubing is still common, in modern times other materials, such as titanium, aluminium, magnesium, and carbon-fibre, along with composites of these materials, are now used. As different motorcycles have varying design parameters (such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
