BSA B40
The BSA B40 was a series of unit construction single-cylinder OHV four-stroke motorcycles made by the Birmingham Small Arms Company. Developed from the BSA C15, the machines were produced between 1961 and 1967 for civilian use. Military versions were manufactured from 1967 to 1970. Around 14,000 machines were built in total. Overview As a reaction to the emergence of high-tech, high performance Honda lightweights that were starting to appear (Mike Hailwood had won the 1961 Lightweight TT on a DOHC, twin-cylinder, 125 cc machine), BSA increased the performance its lightweight by boring the C15 out to 350 cc. The 67 mm bore of the C15 was increased to 79 mm to give a capacity of 343 cc for the new B40 model. Although the bottom end was beefed up, it still retained the plain big end. Concerns over reliability led to the compression ratio to be reduced to 7:1. A new cast iron barrel was produced with the pushrod tunnel built in. The engine produced at 7,000 rpm. C15 cyc ...

BSA Motorcycles
BSA motorcycles were made by the Birmingham Small Arms Company Limited (BSA), which was a major British industrial combine, a group of businesses manufacturing military and sporting firearms; bicycles; motorcycles; cars; buses and bodies; steel; iron castings; hand, power, and machine tools; coal cleaning and handling plants; sintered metals; and hard chrome process. A government-organised rescue operation in 1973 led to the takeover of BSA-Triumph motorcycle operations by Norton-Villiers, later known as Norton Villiers Triumph. At its peak, BSA (including Triumph) was the largest motorcycle producer in the world. In the late 1950s and early 1960s poor management and failure to develop new products in the motorcycle division led to a dramatic decline of sales to its major USA market. The management had failed to appreciate the importance of the resurgent Japanese motorcycle industry, leading to problems for the entire BSA group. When Norton Villiers Triumph was liquidated in ...

1962 BSA B40 At Long Melford 26th Annual Vintage Rally 2009
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Roller Bearing
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls on to it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them. See " bearings" for more on the historical development of bearings. A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called "rollers" tightly fill the space between t ...

Motorcycle Trials
Motorcycle trials, also known as observed trials, often called simply trial/s (with or without the plural "s"), is a non-speed event on specialized motorcycles. The sport is most popular in the United Kingdom and Spain, though there are participants around the globe. Modern trials motorcycles are distinctive in that they have evolved to become extremely lightweight, lack seating (they are designed to be ridden standing up) and have suspension travel that is short, relative to a motocross or enduro motorcycle. Motorcycle trials is often utilized by competitors in other motorcycle sports (such as enduro, motocross or road racers) as a way to cross-train, as trials requires fine throttle, balance, and machine control. Characteristics The event is split into sections where a competitor rides through an obstacle course while attempting to avoid touching the ground with their feet. The obstacles in the course may be of natural or constructed elements. In all sections, regardless of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enduro
Enduro is a form of motorcycle sport run on extended cross-country, off-road courses. Enduro consists of many different obstacles and challenges. The main type of enduro event, and the format to which the World Enduro Championship is run, is a time-card enduro, whereby a number of stages are raced in a time trial against the clock. Time-keeping enduros In a traditional time-keeping enduro, riders leave together in groups or rows, and each row starts at a certain minute. The object of the event is to arrive at pre-defined checkpoints according to a strict schedule. Early or late arrivals result in the riders' scores being penalized. Throughout a day there will also be allocated periods for refuelling and servicing the machine. Penalties apply for not meeting defined times or for outside-assistance when not permitted.Brief History of Enduro', Enduro 411, AMA Western Checkpoint Enduro Championship, retrieved 20 February 2012 Enduros and rallies There are two different types of ...

Telescopic Fork
A telescopic fork is a form of motorcycle front suspension whose use is so common that it is virtually universal. The telescopic fork uses fork tubes and sliders which contain the springs and dampers. The main advantages of the telescopic fork are that (i) it is simple in design and relatively cheap to manufacture and assemble; (ii) it is lighter than older designs using external components and linkage systems; and (iii) it has a clean and simple appearance that bikers find attractive. Telescopic forks sometimes have gaiters to protect the fork tubes from abrasion and corrosion. A more modern (and more expensive) version of the conventional telescopic fork is the inverted or "USD" (upside-down) fork. BMW's patented telelever front suspension appears at first glance to be conventional telescopic fork, but the fork tubes contain neither springs nor damping. Instead, a wishbone and an inboard monoshock perform suspension duties, and the forks serve to locate the front wheel an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pushrod
A valvetrain or valve train is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. The intake valves control the flow of air/fuel mixture (or air alone for direct-injected engines) into the combustion chamber, while the exhaust valves control the flow of spent exhaust gasses out of the combustion chamber once combustion is completed. Layout The valvetrain layout is largely dependent on the location of the camshaft. The common valvetrain configurations for piston engines - in order from oldest to newest - are: * Flathead engine: The camshaft and the valves are located in the engine block below the combustion chamber. * Overhead valve engine: The camshaft remains in the block, however the valves are located in the cylinder head above the combustion chamber. * Overhead camshaft engine: The valves and camshaft(s) are in the cylinder head above the combustion chamber. Components The valvetrain consists of all the compo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...
