BSA B31
The BSA B31 is a motorcycle that was produced by Birmingham Small Arms Company. The BSA B31, introduced in 1945, was the first new model introduced by the company after the Second World War. Based on pre-war designs, it used a single cylinder four stroke engine that displaced . Initially, it had a rigid frame and telescopic forks, the first use of such on a BSA. It developed about , adequate for the roads of the day and enough to deliver a top speed of around .There was a competition kit available for the original rigid model B31 and B33. It was immediately popular and was soon joined by a version, the BSA B33 and competition equivalents, the BSA B32 and BSA B34; the side-car versions, with stiffer suspension and different final demultiplication, were known as BB31 and BB33. Plunger rear suspension was offered later, with a swingarm rear suspension frame available from 1954. The model continued in production until 1959, by which time the traditional Lucas magdyno had been rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ignition Coil
An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system that transforms the battery's voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. Some coils have an internal resistor, while others rely on a resistor wire or an external resistor to limit the current flowing into the coil from the car's 12-volt supply. The wire that goes from the ignition coil to the distributor and the high voltage wires that go from the distributor to each of the spark plugs are called spark plug wires or high tension leads. Originally, every ignition coil system required mechanical contact breaker points and a capacitor (condenser). More recent electronic ignition systems use a power transistor to provide pulses to the ignition coil. A modern passenger automobile may use one ignition coil for each engine cylinder (or pair of cylinders), eliminating fault-prone spark plug cables and a distributor to ro ...

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 ...

Overhead Valve Engine
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 succe ...

Sidecar
A sidecar is a one-wheeled device attached to the side of a motorcycle, scooter, or bicycle, making the whole a three-wheeled vehicle. A motorcycle with a sidecar is sometimes called a ''combination'', an ''outfit'', a ''rig'' or a ''hack''. History Jean Bertoux, a French army officer, secured a prize offered by a French newspaper in 1893 for the best method of carrying a passenger on a bicycle. The sidecar wheel was mounted on the same lateral plane as the bicycle's rear and was supported by a triangulation of tubes from the bicycle. A sprung seat with back rest was mounted above the cross-member and a footboard hung below. A sidecar appeared in a cartoon by George Moore in the January 7, 1903, issue of the British newspaper '' Motor Cycling''. Three weeks later, a provisional patent was granted to Mr. W. J. Graham of Graham Brothers, Enfield, Middlesex. He partnered with Jonathan A. Kahn to begin production. One of Britain's oldest sidecar manufacturers, Watsonian, was fou ...

BSA M33-10
The BSA M33-10 was a British motorcycle made by BSA at their factory in Small Heath, Birmingham in 1933. Development The M33-10 was developed as a 5.95 hp side valve based on the earlier BSA Sloper The BSA S-Series of motorcycles, most commonly known as the BSA Sloper, were a series of motorcycles produced by the Birmingham Small Arms Company (BSA) from 1927 to 1935. Launched in 1927, the 493cc overhead valve engine was slanted, and the m ... with capacity extended to 595cc to make it more suitable for use with a sidecar. In 1934 M33-10 was replaced by the M34-12 'de Luxe' side valve and the M34-13 overhead valve 'de Luxe' models, both of which had 5.95 hp engines.

BSA Gold Star
The BSA Gold Star is a motorcycle made by BSA from 1938 to 1963. They were 350 cc and 500 cc single-cylinder four-stroke production motorcycles known for being among the fastest bikes of the 1950s. Being hand built and with many optional performance modifications available, each motorcycle came from the factory with documented dynamometer test results, allowing the new owner to see the horsepower (bhp) produced. The Gold Star was almost continuously developed over its lifetime by BSA's engineers and riders, who improved its capabilities and increased output from its essentially simple push-rod petrol engine than had been thought possible. It was highly successful across almost all areas of motorcycle sport for well over a decade and is still regarded as a design icon of its era. Origin In 1937, Wal Handley lapped the Brooklands circuit at over on a BSA Empire Star, and was awarded one of the traditional Gold Star badges. That inspired BSA to produce the BSA Gold S ...

Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swingarm
A swingarm, or "swinging arm" (UK), originally known as a swing fork or pivoted fork, is a single or double sided mechanical device which attaches the rear wheel of a motorcycle to its body, allowing it to pivot vertically. The main component of the rear suspension of most modern motorbikes and ATVs, it holds the rear axle firmly, while pivoting to absorb bumps and suspension loads induced by the rider, acceleration, and braking. Originally motorcycles had no rear suspension, as their frames were little more than stronger versions of the classic diamond frame of a bicycle. Many types of suspension were tried, including Indian's leaf spring suspended swingarm, and Matchless's cantilevered coiled-spring swingarm. Immediately before and after World War II, the plunger suspension, in which the axle moved up and down two vertical posts, became commonplace. In the latter, the movement in each direction was against coiled springs. Some manufacturers, such as Greeves, used swingarm d ...

Suspension (motorcycle)
A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations. The typical motorcycle has a pair of fork tubes for the front suspension, and a swingarm with one or two shock absorbers for the rear suspension. Front suspension The most common form of front suspension for a modern motorcycle is the telescopic fork. Other fork designs are girder forks, suspended on sprung parallel links (not common since the 1940s) and bottom leading link designs, not common since the 1960s. Some manufacturers (e.g. Greeves) used a version of the swinging arm for front suspension on their motocross designs. A single-sided version of the idea is also used in motor scooters such as the Vespa. The hub-center steering as developed by Ascanio Rodorigo, on a concept associated to Massimo Tamburini is a complex front swingarm alternat ...
